            1.   The use of vessel tracking and tracing in inland navigation
      1.1.   Introduction
      In maritime navigation, IMO has introduced the automatic identification system (AIS). All seagoing vessels on international voyage falling under SOLAS convention Chapter 5 have to be equipped with AIS since the end of 2004. The guidelines for the planning, implementation and operational use of River Information Services define Inland-AIS as an important technology. Because of mixed traffic areas it is important that the standards, technical specifications and procedures for inland shipping are compatible with already defined standards, technical specifications and procedures for seagoing navigation.
      To serve the specific requirements of inland navigation, AIS has been further developed to the so called Inland AIS technical specification while preserving full compatibility with IMO's maritime AIS and already existing standards in inland navigation.
      In this document chapter 1 describes the functional specifications related to vessel tracking and tracing in inland navigation. In chapter 2 the inland AIS technical specification is described, including the standard inland tracking and tracing messages. An overview of definitions of services and players is given in Appendix A: Definitions.
      The purpose of the introduction chapter is to define all necessary functional requirements related to vessel tracking and tracing in inland navigation.
      An overview of fields of interest and users is provided and particularly the information needs for each field of interest are described. The functional specifications are based on rules and regulations for navigation, based on discussions with experts and based on existing experiences.
      Three groups of information are distinguished:
      
                  —
               
               
                  Dynamic information, information changing very often in seconds or minutes.
               
            
                  —
               
               
                  Semi-dynamic information, information changing just a few times a voyage.
               
            
                  —
               
               
                  Static information, information changing less then a few times a year.
               
            For each group of information different ways of information exchange can be identified:
      
                  —
               
               
                  Vessel Tracking and tracing systems shall exchange particularly the dynamic information.
               
            
                  —
               
               
                  Electronic reporting devices, like email, are meant to exchange the semi-dynamic information.
               
            
                  —
               
               
                  Data bases are meant to provide static information which can be retrieved via Internet or other data carries.
               
            In the paragraphs below that information is described in detail which can be exchanged by vessel tracking and tracing systems between ships and between ships and shore. The information needs are described relating to tracking and tracing. However, for most of the tasks additional information like geographical information, detailed cargo information, address information is required. This kind of information will be provided by other systems.
      1.2.   Scope
      The table below gives an overview of the fields of interest dealt with in this document. Each field of interest is split up into tasks and for each task the users are defined.

         Note: the order of the information needs within each task does not imply different importance of the information. The accuracy of the information needs is summarised in a table in the last paragraph.
      1.3.   Navigation
      Vessel tracking and tracing can be used to support the active navigation on board.
      The process navigation can be split up in three phases:
      
                  —
               
               
                  navigation, medium-term ahead,
               
            
                  —
               
               
                  navigation, short-term ahead,
               
            
                  —
               
               
                  navigation, very short-term ahead.
               
            For each phase the user requirements are different.
      1.3.1.   Navigation, medium term ahead
      Navigation a medium term ahead is the navigation phase in which the skipper observes and analyses the traffic situation looking some minutes up to an hour ahead and considers the possibilities of where to meet, pass or overhaul other vessels.
      The traffic image needed is the typical ‘looking around the corner’ feature and is mainly outside the scope of the on board radar range.
      Exchanged traffic information consist of:
      
                  —
               
               
                  identification,
               
            
                  —
               
               
                  name,
               
            
                  —
               
               
                  position (actual),
               
            
                  —
               
               
                  speed over ground,
               
            
                  —
               
               
                  course over ground/direction,
               
            
                  —
               
               
                  destination/intended route,
               
            
                  —
               
               
                  vessel and convoy type,
               
            
                  —
               
               
                  dimensions (length and beam),
               
            
                  —
               
               
                  number of blue cones,
               
            
                  —
               
               
                  loaded/unloaded,
               
            
                  —
               
               
                  navigational status of the vessel (anchoring, mooring, sailing, restricted by special conditions, …).
               
            The update rate is depending on the task and differs from the situation in which the ship is involved. (The maximum update rate is two seconds.)
      1.3.2.   Navigation, short-term ahead
      Navigation a short-term ahead is the decision phase in the navigation process. In this phase traffic information has relevance for the process of navigation, including collision avoidance measures if necessary. This function deals with the observation of other vessels in the close surroundings of the vessel. Exchanged traffic information consists of:
      
                  —
               
               
                  identification,
               
            
                  —
               
               
                  name,
               
            
                  —
               
               
                  position (actual),
               
            
                  —
               
               
                  speed over ground (accuracy 1 km/h),
               
            
                  —
               
               
                  course over ground/direction,
               
            
                  —
               
               
                  heading,
               
            
                  —
               
               
                  intention (blue sign),

                  —
               
               
                  dimensions (length and beam),
               
            
                  —
               
               
                  number of blue cones,
               
            
                  —
               
               
                  loaded/unloaded,
               
            
                  —
               
               
                  navigational status of the vessel (anchoring, mooring, sailing, restricted by special conditions, …).
               
            The actual traffic information on position, identification, name, direction, speed over ground, course, heading and intention (blue sign) will be exchanged continuously at least every 10 seconds. For some routes the Authorities will set a predefined update rate (maximum two seconds).
      1.3.3.   Navigation, very short term ahead
      Navigation a very short term ahead is the operational navigation process. It consists of execution of the decisions that were made beforehand, on the spot and monitoring its effects. The traffic information needed from other vessels especially in this situation is related to its own vessel conditions, such as relative position, relative speed, etc. In this phase following highly accurate information is needed:
      
                  —
               
               
                  relative position,
               
            
                  —
               
               
                  relative heading,
               
            
                  —
               
               
                  relative speed,
               
            
                  —
               
               
                  relative drift,
               
            
                  —
               
               
                  relative rate of turn.
               
            Based on the abovementioned requirements it became clear that from today's point of view very short term navigation can not make use of tracking and tracing information.
      1.4.   Vessel traffic management
      Vessel traffic management comprises at least of the below defined elements:
      
                  —
               
               
                  vessel traffic services,
               
            
                  —
               
               
                  lock planning and operation,
               
            
                  —
               
               
                  bridge planning and operation.
               
            1.4.1.   Vessel traffic services
      Within vessel traffic services different services can be distinguished:
      
                  —
               
               
                  an information service,
               
            
                  —
               
               
                  a navigational assistance service,
               
            
                  —
               
               
                  a traffic organisation service.
               
            In the next paragraphs the user needs related to traffic information are described.
      1.4.1.1.   Information service
      
      An information service is provided by broadcasting information at fixed times and intervals or when deemed necessary by the VTS or at the request of a vessel, and may include for example reports on the position, identity and intentions of other traffic; waterway conditions; weather; hazards; or any other factors that may influence the vessel's transit.
      For the information services an overview of traffic in a network or on fairway stretch is needed. The traffic information will comprise vessel information like:
      
                  —
               
               
                  identification,
               
            
                  —
               
               
                  name,
               
            
                  —

                  —
               
               
                  course over ground/direction,
               
            
                  —
               
               
                  limitations on navigable space,
               
            
                  —
               
               
                  destination/intended route,
               
            
                  —
               
               
                  vessel and convoy type,
               
            
                  —
               
               
                  dimensions (length and beam),
               
            
                  —
               
               
                  number of blue cones,
               
            
                  —
               
               
                  loaded/unloaded,
               
            
                  —
               
               
                  number of persons on board (in case of an incident),
               
            
                  —
               
               
                  navigational status of the vessel (anchoring, mooring, sailing, restricted by special conditions, …).
               
            The competent authority will set the predefined update rate.
      1.4.1.2.   Navigational assistance service
      
      A navigational assistance service informs the master on difficult navigational or meteorological circumstances or assists him in case of defects or deficiencies. This service is normally rendered at the request of a vessel or by the VTS when deemed necessary.
      To provide individual information to a skipper, the VTS operator needs an actual detailed traffic image.
      The contribution of vessel tracking and tracing is:
      
                  —
               
               
                  identification,
               
            
                  —
               
               
                  name,
               
            
                  —
               
               
                  position (actual),
               
            
                  —
               
               
                  speed over ground,
               
            
                  —
               
               
                  course over ground/direction,
               
            
                  —
               
               
                  intention (blue sign),
               
            
                  —
               
               
                  destination/intended route,
               
            
                  —
               
               
                  vessel and convoy type,
               
            
                  —
               
               
                  dimensions (length and beam),
               
            
                  —
               
               
                  draught,
               
            
                  —
               
               
                  air draught (in case of obstacles),
               
            
                  —
               
               
                  number of blue cones,
               
            
                  —
               
               
                  loaded/unloaded,
               
            
                  —
               
               
                  navigational status of the vessel (anchoring, mooring, sailing, restricted by special conditions, …).
               
            Any other information needed is environmental, geographic information and Notices to Skippers.
      The actual traffic information on identification, position, direction, speed, course and intention (blue sign) has to be exchanged continuously (every three seconds, almost real time or another predefined update rate set by the competent authority).
      All other information had to be available on request of the VTS operator or in special occasions (on event).
      1.4.1.3.   Traffic organisation service
      
      A traffic organisation service concerns the operational management of traffic and the forward planning of vessel movements to prevent congestion and dangerous situations, and is particularly relevant in times of high traffic density or when the movement of special transports may affect the flow of other traffic. The service may also include establishing and operating a system of traffic clearances or VTS sailing plans or both in relation to priority of movements, allocation of space, mandatory reporting of movements in the VTS area, routes to be followed, speed limits to be observed or other appropriate measures which are considered necessary by the VTS authority. The requirements on the traffic image for the traffic organisation service are the same as described in paragraph 1.4.1.2 Navigational assistance service.
      1.4.2.   Lock planning and operation
      In the next paragraphs the lock planning processes — long- and medium-term — and lock operation process are described.
      1.4.2.1.   Lock planning, long-term
      
      Lock planning a long-term ahead is dealing with the planning of a lock some hours up to a day ahead.
      In this case the traffic information is used to improve the information on waiting and passing times at locks, which are originally based on statistical information.
      Traffic information needed for long term lock planning is:
      
                  —
               
               
                  identification,
               
            
                  —
               
               
                  name,
               
            
                  —
               
               
                  position (actual),
               
            
                  —
               
               
                  course over ground/direction,
               
            
                  —
               
               
                  ETA at lock,
               
            
                  —
               
               
                  RTA at lock,
               
            
                  —
               
               
                  vessel and convoy type,
               
            
                  —
               
               
                  dimensions (length and beam),
               
            
                  —
               
               
                  draught,
               
            
                  —
               
               
                  air draught,
               
            
                  —
               
               
                  number of blue cones,
               
            
                  —
               
               
                  navigational status of the vessel (anchoring, mooring, sailing, restricted by special conditions, …).
               
            ETA should be available on demand or should be exchanged when a by the competent authority predefined deviation of the originally ETA is exceeded. RTA is the response on an ETA report.
      1.4.2.2.   Lock planning medium-term
      
      Lock planning a medium-term ahead is dealing with the planning of a lock up to two or four lock cycles ahead.
      In this case the traffic information is used to map the arriving vessels to the available lock cycles and based on the planning to inform the skippers about the RTA (requested time of arrival).
      Traffic information needed for medium term lock planning is
      
                  —

                  —
               
               
                  course over ground/direction,
               
            
                  —

                  —
               
               
                  dimensions (length and beam),
               
            
                  —

                  water levels.
               
            In the next paragraphs, the provided information is described.
      1.9.1.   Weather warnings (EMMA)
      The European ongoing project ‘EMMA’ (European multiservice meteorological awareness system) is dealing with standardisation of weather warnings. Standardised symbols for meteorological warnings have been developed within the EMMA project and can be used for the display of messages on the Inland ECDIS screen.
      EMMA is not going to provide continuous weather information, but only warnings in case of special meteorological situations. The warnings are provided for regions.
      Only km/h (wind), oC (temperature), cm/h (snow), l/m2h (rain) and m (distance to be seen by fog) may be used for weather warnings.
      The following information is needed:
      
                  —

                  —
               
               
                  type of weather warning (see Appendix B),
               
            
                  —
               
               
                  minimum value,
               
            
                  —
               
               
                  maximum value,
               
            
                  —
               
               
                  classification of warning,
               
            
                  —
               
               
                  direction of wind (see Appendix B).
               
            This information is only exchanged in special events, in case of extreme weather conditions.
      1.9.2.   Signal status
      Vessel tracking and tracing systems can be used for the transmission of status of traffic signals in inland navigation. The information to be exchanged consists of:
      
                  —
               
               
                  the position of the signal,
               
            
                  —
               
               
                  an identification of the kind of signal (single light, two lights, ‘Wahrschau’, etc.),
               
            
                  —

            2.   INLAND AIS TECHNICAL SPECIFICATION
      2.1.   Introduction
      In maritime navigation, IMO has introduced the automatic identification system (AIS). All seagoing ships on international voyage falling under SOLAS convention Chapter 5 have to be equipped with AIS since the end of 2004.
      The European Parliament and the Council have adopted Directive 2002/59/EC (2) establishing a community vessel traffic monitoring and information system for seagoing vessels carrying dangerous or polluting goods using AIS for Ship Reporting and Monitoring.
      AIS technology is considered as a suitable way that can also be used for automatic identification and vessel tracking and tracing in inland navigation. Especially the real time performance of AIS and the availability of worldwide standards and guidelines are beneficial for safety related applications.
      To serve the specific requirements of inland navigation, AIS has to be further developed to the so-called Inland AIS technical specification while preserving full compatibility with IMO's maritime AIS and already existing standards and technical specifications in inland navigation.
      Because Inland AIS is compatible to the IMO SOLAS AIS it enables a direct data exchange between seagoing and inland vessels navigating in mixed traffic areas.
      Using AIS for automatic identification and vessel tracking and tracing in inland navigation provides the following features:
      AIS is:

                  interoperability.
               
            The purpose of this document is to define all necessary functional requirements, amendments and extensions to the existing maritime AIS in order to create an Inland AIS for use in inland navigation.
      2.2.   Scope
      The AIS is a ship-borne radio data system, exchanging static, dynamic and voyage related vessel data between equipped vessels and between equipped vessels and shore stations. Ship-borne AIS stations broadcast the vessel's identity, position and other data in regular intervals. By receiving these transmissions, ship-borne or shore-based AIS stations within the radio range can automatically locate, identify and track AIS equipped vessels on an appropriate display like radar or Inland ECDIS. AIS systems are intended to enhance safety of navigation in ship-to-ship use, surveillance (VTS), vessel tracking and tracing, and calamity abatement support.
      Several types of AIS stations can be distinguished:
      
                  (a)
               
               
                  Class A mobile stations to be used by all sea going vessels falling under the IMO SOLAS chapter V carriage requirements;
               
            
                  (b)
               
               
                  Class B SO/CS mobile stations with limited functionality to be used by e.g. pleasure crafts;
               
            
                  (c)
               
               
                  Class A derivatives, having full class A functionality on VDL level, may deviate in supplementary functions and can be used by all vessels not falling under IMO carriage requirements (e.g. tugs, pilot vessels, inland vessels (to be called Inland AIS in this document),
               
            
                  (d)
               
               
                  base stations, including shore based simplex and duplex repeater stations.
               
            The following modes of operation can be distinguished:
      
                  (e)
               
               
                  ship-to-ship operation: all AIS equipped vessels are able to receive static and dynamic information from all other AIS equipped vessels within the radio range;
               
            
                  (f)
               
               
                  Ship-to-shore operation: data from AIS equipped vessels can also be received by AIS base stations connected to the RIS centre where a traffic image (TTI and/or STI) can be generated;
               
            
                  (g)
               
               
                  Shore-to-ship operation: safety related data from shore to vessel could be transmitted.
               
            A characteristic of AIS is the autonomous mode, using SOTDMA without any need for an organising master station. The radio protocol is designed in a way that vessel stations operate autonomously in a self-organised manner by exchanging link access parameters. Time is divided into one minute frames with 2 250 time slots per radio channel which are synchronised by GNSS UTC time. Each participant organises its access to the radio channel by choosing free time slots considering the future use of time slots by other stations. There is no need for a central intelligence controlling the slot assignment.
      An Inland AIS station consists in general of the following components:
      
                  (h)
               
               
                  VHF transceiver (one transmitter/two receivers);
               
            
                  (i)
               
               
                  GNSS receiver;
               
            
                  (j)
               
               
                  data processor.
               
            Universal ship-borne AIS, as defined by IMO, ITU and IEC, and recommended for the use in inland navigation uses self-organised time division multiple access (SOTDMA) in the VHF maritime mobile band. AIS operates on the internationally designated VHF frequencies AIS 1 (161,975 MHz) and AIS 2 (162,025 MHz), and can be switched to other frequencies in the VHF maritime mobile band.
      To serve the specific requirements of inland navigation, AIS has to be further developed to the so called Inland AIS while preserving compatibility with IMO's maritime AIS.
      Vessel tracking and tracing systems in inland navigation shall be compatible with maritime AIS, as defined by IMO. Therefore, AIS messages shall contain:
      
                  (k)
               
               
                  Static information, such as official ship number, call sign of vessel, name of vessel, type of vessel;
               
            
                  (l)
               
               
                  Dynamic information, such as vessels position with accuracy indication and integrity status;

                  Inland navigation specific information, e.g. number of blue cones/lights according to ADN/ADNR or estimated time of arrival (ETA) at lock/bridge/terminal/border.
               
            For moving vessels an update rate for the dynamic information on tactical level can be switched between SOLAS mode and inland mode. In inland waterway mode it can be assigned between two seconds and 10 minutes. For vessels at anchor it is recommended to have an update rate of several minutes, or if information is amended.
      AIS is an additional source for navigational information. AIS does not replace, but supports navigational services such as radar target tracking and VTS. AIS has its strength as a means of surveillance and tracking of vessels equipped with it. Due to their different characteristics, AIS and radar complement each other.
      2.3.   Functional requirements
      2.3.1.   General requirements for Inland AIS
      Inland AIS is based on the maritime AIS according to IMO SOLAS regulation.
      Inland AIS shall cover the main functionality of IMO SOLAS AIS while considering the specific requirements for inland navigation.
      Inland AIS shall be compatible to the IMO SOLAS AIS and shall enable a direct data exchange between seagoing and inland vessels navigating in a mixed traffic area.
      The following requirements are complementary or additional requirements for Inland AIS, which differs from the IMO SOLAS AIS.
      2.3.2.   Information content
      Generally only tracking and tracing and safety related information shall be transmitted via Inland AIS. Taking into consideration this requirement, Inland AIS messages shall contain following information:
      Items marked with ‘*’ have to be handled differently as for seagoing ships.
      2.3.2.1.   Static ship information
      
      The static ship information for inland vessels shall have the same parameters and the same structure as in IMO AIS as far as it is applicable. Not used parameter fields shall be set to ‘not available’.
      Inland specific static ship information shall be added.
      Static ship information is broadcast autonomously from ship or on request.

      2.3.3.   Reporting interval of information transmission
      
      The different information types of Inland AIS shall be transmitted with different reporting rates.
      For moving vessels in inland waterway areas the reporting rate for the dynamic information can be switched between SOLAS mode and inland waterway mode. In inland mode it can be assigned between two seconds and 10 minutes. In mixed traffic areas like seaports it shall be possible to decrease the reporting rate for dynamic information by the competent authority to ensure a balance in reporting behaviour between inland vessels and SOLAS vessels. The reporting behaviour shall be switchable by TDMA commands from a base station (automatic switching by TDMA telecommand via message 23) and by commands from ship-borne systems, e.g. MKD, ECDIS or on board computer, via interface, e.g. IEC 61162 (automatic switching by ship-borne system command). For static and voyage related information it is recommended to have a reporting rate of several minutes, on request, or if information is amended.
      Following reporting rates are applicable:
      
                  Static ship information:
               
               
                  Every six minutes or when data has been amended or on request
               
            
                  Dynamic ship information:
               
               
                  Depends on navigational status and ship operating mode, either inland waterway mode or SOLAS mode (default), see Table 2.1
               
            
                  Voyage related ship information:
               
               
                  Every six minutes, when data has been amended or on request
               
            
                  Traffic management information:
               
               
                  As required (to be defined by competent authority)
               
            
                  Safety related messages:

                  Assigned between two seconds and 10 minutes
               
            2.3.4.   Technology platform
      The technical solution of Inland AIS is based on the same technical standards as IMO SOLAS AIS (Rec. ITU-R M.1371-1, IEC 61993-2).
      The use of Class A mobile station derivates or Class B ‘SO’ mobile station derivates using SOTDMA techniques are recommended as platform for Inland AIS. The use of the Class B ‘CS’ using CSTDMA techniques is not possible, because it does not guarantee the same performance as the Class A or Class B ‘SO’ equipment. Neither can the successful transmission to radio link be granted nor does it provide the capability to send the Inland AIS specific messages defined in this technical specification.
      As long as no Class B ‘SO’ devices are available, Inland AIS Mobile equipment is a derivative of the maritime AIS Class A mobile equipment according IMO SOLAS regulation.
      2.3.5.   Compatibility to IMO Class A transponders
      Inland AIS transponders must be compliant to IMO Class A transponders and must therefore be capable of receiving and processing all IMO AIS messages (according to ITU-R M.1317-1 and IALA technical clarifications on ITU-R M.1371-1) and in addition the messages defined in Chapter 2.4 of these standards.
      The DSC transmitting (tx) capability and the provision of an MKD are not required for Inland AIS transponders. The manufacturers may remove the respective hard- and software from the Class A transponders.
      2.3.6.   Unique identifier
      In order to guarantee the compatibility to maritime vessels, the Maritime Mobile Service Identifier (MMSI) number must be used as a unique station identifier (radio equipment identifier) for the Inland AIS transponders.
      2.3.7.   Application identifier for Inland AIS application specific messages
      To serve the information requirement for inland navigation application specific messages are used.
      The application specific messages consist of the Standard AIS framework (message ID, repeat indicator, source ID, destination ID), the Application Identifier (AI = DAC + FI) and the data content (variable length up to a given maximum).
      The 16-bit application identifier (AI = DAC + FI) consists of
      
                   
               
               
                  10-bit designated area code (DAC): international (DAC = 1) or regional (DAC > 1)
               
            
                   
               
               
                  6-bit function identifier (FI) — allows for 64 unique application specific messages.
               
            For Inland AIS application specific messages the DAC ‘200’ is used.
      2.3.8.   Application requirements
      It is necessary to input and display Inland AIS messages (binary coded). This shall be handled by an application (preferably with a GUI capable of interfacing the AIS transponder) at the Presentation Interface (PI), or in the transponder itself. Possible data conversions (e.g. knots into km/h) or information concerning all ERI codes (location, ship type) shall be handled there.
      Furthermore the transponder or the relevant application shall be capable of storing also the inland specific static data in the internal memory, in order to keep the information when the unit is without power supply.
      In order to program the inland specific data into the transponder the input sentences listed in Appendix D: Proposed digital interface sentences for Inland AIS are proposed.
      The Inland AIS equipment shall provide as a minimum an external RTCM SC 104 interface for the input of DGNSS correction and integrity information.

               Vessel traffic services (VTS)
         Vessel traffic service is a service implemented by a competent authority, designed to improve the safety and efficiency of vessel traffic and to protect the environment.
         The service shall have the capability to interact with the traffic and to respond to traffic situations developing in the area.
         VTS services — VTS shall comprise at least an information service and may also include others, such as a navigational assistance service, or a traffic organisation service, or both, defined as below:

                     a navigational assistance service is a service to assist on-board navigational decision-making and to monitor its effects. Navigational assistance is especially of importance in reduced visibility or difficult meteorological circumstances or in case of defects or deficiencies affecting the radar, steering or propulsion. Navigational assistance is given in due form of position information at the request of the traffic participant or in special circumstances when deemed necessary by the VTS operator,

            VTS area is the delineated, formally declared service area of the VTS. A VTS area may be subdivided in sub-areas or sectors. (Source: IALA VTS guidelines)
         
            Navigational information is information provided to the skipper on board to support in on-board decision-making. (Source: IALA VTS guidelines)
         
            Tactical traffic information (TTI) is the information affecting the skipper's or the VTS operator's immediate decisions with respect to in the actual traffic situation and the close geographic surroundings. A tactical traffic image contains position information and specific vessel information of all targets detected by a radar presented on an Electronic Navigational Chart and — if available — enhanced by external Traffic Information, such as the information delivered by an AIS. TTI may be provided on board of a vessel or on shore, e.g. in a VTS Centre. (Source: RIS guidelines)
         
            Strategic traffic information (STI) is the information affecting the medium and long-term decisions of RIS users. A strategic traffic image contributes to the planning decision capabilities regarding a safe and efficient voyage. A strategic traffic image is produced in a RIS centre and delivered to the users on demand. A strategic traffic image contains all relevant vessels in the RIS area with their characteristics, cargoes and positions, reported by VHF voice reporting or electronic ship reporting, stored in a database and presented in a table or on an electronic map. Strategic Traffic Information may be provided by a RIS/VTS centre or by an office. (Source: RIS guidelines)

         Example of signal status
         C.1   Light status
         
            
         The examples show a grey background in a square of a fixed size of about 3 mm x 3 mm at all display scales with a ‘post’ like it is used for the present static signal in the presentation library. The white point in the centre of the post indicates the position and the post itself allows the user to read the direction of impact. (At a lock, for example, there are often signals for vessels leaving the lock chamber and vessels entering the lock chamber on the inner and the outer side of the door construction) However, the manufacturer of the display software can design the shape of the symbol and the background colour.
         The status of a signal can be ‘No light’, ‘white’, ‘yellow’, ‘green’, ‘red’, ‘white flashing’ and ‘yellow flashing’ according to CEVNI.
         C.2   Signal forms
         
            
         
            
         
            
         
            
         
            
         For each of these signals there are a lot of possible combinations of lights. It is required to use:
         a number to indicate the kind of signal, and
         a number for each light on a signal to indicate its status:
         
                     1 =
                  
                  
                     no light,

         Appendix D
         PROPOSED DIGITAL INTERFACE SENTENCES FOR INLAND AIS
         D.1   Input sentences
         The serial digital interface of the AIS is supported by existing IEC 61162-1 sentences and new IEC 61162-1 like sentences. The detailed descriptions for the digital interface sentences are found in either IEC 61162-1 edition 2, or in ‘Publicly Available Specification’ IEC PAS 61162-100.
         This appendix contains draft information used during the development of Inland AIS in order to input the inland specific data (see) into the Inland AIS shipboard unit. New IEC 61162-1 sentences have to be specified. Prior to an adoption of approved sentences for Inland AIS by IEC 61162-1, proprietary sentence shall be used.
         D.2   Inland waterway static ship data
         This sentence is used to enter inland navigation static ship data into an Inland AIS unit. For setting the inland static ship data the sentence $PIWWSSD with the following content is proposed:
         
            
         
                     Note 1

               D.3   Inland waterway voyage data
         This sentence is used to enter inland navigation voyage ship data into a Inland AIS unit. For setting the inland voyage related data the sentence $PIWWIVD with the following content is proposed:

            Remark: The former proposed input sentence $PIWWVSD, used in Inland AIS units developed prior this standard, contains the parameter field ‘blue sign’ which may raise conflicts with the parameter field ‘regional application flags’ in the $—VSD sentence according IEC 61162-1:VSD-AIS Voyage static data.
         It shall no longer be implemented in new AIS transponders. However, for compatibility reasons, it shall be supported by external applications.
