Keeping the time table is getting more and more difficult with the increasing local traffic. The public transport companies and the local governments try to give preference to the public transport. They set limits to cars driving in the centre of the city, form bus lanes, etc.

Our company developed a complex technological solution, which increases the average speed of the vehicles of the public transport and decreases the journey time. The function is called „Green way request”.

The main point of the function is that vehicles may request green light in the appointed junctions from the traffic light controller. This means, that the vehicle may intervene in the operation of the traffic light contoller directly. The traffic light contoller gives preference to this vehicle according to a pre-programmed plan (strategy). Therefore the green signal for this vehicle will be extended and the running time of the transversal traffic will be decreased with a few seconds. If the vehicle does not need to wait 60-90 seconds at every traffic light, the whole journey time may be decreased significantly. The route may be more punctual, predictable and faster with 5 to 10 controlled junctions. The whole journey time may be decreased with 5 to 7 minutes.

The process of the operation

Each on-board computer has a GPS receiver, knows its own location, speed, route number, route and the current deviation from the time table. If the vehicle is late and comes near to a junction with Green way request module, it requests the green signal in advance (30 seconds) through GPRS connection. The green way card in the traffic light controller starts to time the green signal according to the estimated arrival time of the vehicle. 10 seconds before entering the junction the vehicle performs a narrow range check-in just in case. The system is also able to manage stops right in front of a junction.

We developed the green way card with the help of traffic experts and producers of traffic light controllers. Therefore it is compatible with many traffic light controllers. According to the installations the function decreases the average journey time and speeds up the public transport.
