### Requirements for System Development  
To enable the development of a system that can organize transportation using safer, more reliable, more economical, and more comfortable vehicles, it is necessary to implement the achievements of many fields and, in particular, follow the requirements of, and possibly

These protocols allow a new level of service delivery to be achieved. Services can be arranged in vehicles using the DSRC and the WAVE technology by allowing requirements of ITS development to be achieved, and by promoting road safety, more optimal traffic management, and provision of more comfortable services for drivers. The connection between the vehicle and the roadside units (RSUs) allows the necessary communication. In vehicles, it is possible to equip several types of onboard units (OBUs), and other units are dedicated external application units (AUs) [23; 41; 42]. The ad-hoc networking domain consists of vehicles that are equipped with an OBU. Vehicles can communicate with other vehicles by creating the structures of information, which change directly for the drivers, and comprise the MANET, which allows full distribution of information between vehicles via communication using precise coordination. RSUs can connect to the infrastructure using networks or Internet access points, thus providing the OBU with the ability to access the infrastructure of the network [19; 20; 41; 42; 23]. Attention has been paid to different types of possible transportation scenarios (in cities, across rural areas, crossing border points, uploading at terminals, etc.). In particular, the construction of identification algorithms for the recognition of different situations is needed to assess their importance for transportation management in an online regime. These methods are influenced by the service provision process for drivers. For analyzing warnings, we constructed algorithms that consist of the assessment of conditions of unpredictable situations for which warnings are needed (collisions, lane changing, etc.). To realize these algorithms, it is necessary to include the capability of emergency video transmission and other strategies for the prediction of events. These algorithms can help in the forecasting and re-planning of transportation circumstances, thus resulting in a system with greater predictive abilities for transportation management. The assessed information is disseminated, and the smart system is able to provide the information directly to drivers or receive it in the automatic active safety systems of DWs. Services that provide comfort and entertainment are considered to be less important, and are thus not related to road safety. These types of services can be provided in normal driving situations and can help to improve the comfort of drivers (and/or passengers). Services provided at comfort areas can supply meteorological and traffic information, in addition to the details regarding the location and prices of the nearest petrol stations, hotels, etc. The taxonomy of the VANET can be divided into a number of areas, such as field-level planning, control of the processes' operational performance, and online access during the transportation processes. Architecture of an Intelligent Adaptable Service Delivery System for Cargo Transportation Process Management  
The development of an intelligent adaptive service delivery system (IASDS) requires the integration of the immediate environmental identification and data management techniques. A more detailed conceptual architecture of the smart service provision system is proposed in our previous works [3; 7; 8]. Recently, special attention has been paid to the field of changing the topology of mobile networks and the development of algorithms for restricting the provision of unnecessary information.
