The creation of a centralised control system at bus network scale and its integration into the existing road traffic control system requires sophisticated tools, which proved too time-consuming to develop within the MOBILIS project. The centralised approach was therefore postponed.
Instead, the measure focused on developing and implementing two bus priority systems. Two bus lines were equipped with a priority request system in order to assess the advantages and constraints of the system for both public transport and private car flows.
In the first trial, a radio call priority system was used, which functions via an onboard command box that communicates codes to the traffic light controller.
The second trial focused on buses in the high-quality corridors, which were equipped with beams that activate electromagnetic loops to obtain priority at traffic lights.
