Orlando International Airport APM
IT-ATP (CBTC) signalling system compatible with unattended operation
The Orlando International Airport in Florida, U.S.A. has witnessed a
substantial increase in the number of business travelers as well as
tourists visiting theme parks in the surrounding area. In order toaccommodate the influx of passengers, a project has been executed to
expand and modernize airport facilities and connect interurban railway
services to the intermodal transit complex (South Airport Complex).
Our company has delivered the IT-ATP (CBTC) signalling system thatsupports unattended operation for APM (Automated People Mover) at
approximately 2.3km railway line constructed between the existing
airport terminal and new South Airport Complex.

Signalling System Overview
The Signalling system of APM for Orlando International
Airport consists of IT-ATP (Information Technology ‒Automatic Train Protection), which is Kyosanʼs CBTC(Communications-Based Train Control) system product.
IT-ATP is a train control system that detects trainʼs location
using on-board equipment, and allows bidirectional
continuous radio communications between the train andground. IT-ATP offers train protections such as train location
detection, train interval control, overturning prevention,overspeed protection, train separation protection, zero
speed detection, etc. In addition, since the system isdesigned for unattended operation, the Automatic Train
Operation (ATO) function enables the train to stop at astation with an accuracy of ±150mm.
Furthermore, the system has a function to stop the train
immediately in case of emergency such as a fire on station
and when the doors leading to the evacuation passage
along the railway line are open. In the central control room,
the system enables centralized monitoring of operating
conditions, equipment conditions, train conditions, etc.

Safety is secured for train location detection, train intervalcontrol, route control, point control, platform door control,
train door control, etc., through the use of equipment
compliant with SIL4.
Compared to the train control based on continuous loop
coil method, the number of devices has been substantiallyreduced to achieve space & energy saving as well as
enhanced maintainability.

2.4 GHz band radio is used for bidirectional communication
between the ground and train, which does not require aradio station license. In addition, the use of LCX (LeakyCoaXial cable) allows stable communication resistant toradio interference.
