In the context of its work on traffic light systems for tram line E of the Toulouse light transit system, SPIE Sud-Ouest has chosen SPIE Belgium's Infrastructure Division to supply control equipment to detect the progress of trams along their route.
The Audio Identification System (AISY) provided by SPIE Belgium will comprise 15 point control devices and 285 road junction control devices.
For SPIE Belgium, this contract worth €425,000 marks a new success for its AISY system developed in 1983.
This system is used to detect the movements of public transport vehicles and optimises traffic flow.
Using induction loop technology, it enables equipped vehicles to control traffic lights and access barriers, etc.
Commands to be executed are transmitted by a black box on board the vehicle and are received by a loop laid in the road.
In Belgium, this black box has been installed on 5,000 De Lijn vehicles and the 920 road junctions have been equipped to respond to the signals emitted.
SPIE is also responsible for the system's maintenance.
In the Netherlands, the towns of Uithoorn, Spijkenisse and Schiedam have equipped their bus stations with this system.
The first city in France to adopt the system was Bordeaux, which purchased it in 2001 to equip its entire city centre in order to optimise the smooth running of its light transit system.
An extension phase is planned in 2009 and the Infrastructure Division is holding itself in readiness to start work on this project.
The city of Marseille equipped its junctions with the system for its tram network in 2006.
The Toulouse contract provides SPIE Belgium with another excellent reference.
