Audi Backs Traffic Project To Get Cars Talking To Traffic Lights, Minimize Time Spent At Stops

Audi has thrown its weight behind "Travolution," a German traffic light communication management system trying to smooth traffic flow and reduce congestion. The system works by way of 46 smart traffic lights installed in Audi's home town of Ingolstadt which communicate with specially equipped Audi A5s and A6s. The cars interpret the information from the lights and display an ideal speed to the driver which leads to smooth sailing through green lights as opposed to hitting the reds. The lights also interpret traffic density and adjust timing to reduce times at the line - and therefore minimization of fuel-sapping "stop-start" traffic. Sounds like a plan to us

AUDI BACKED ‘TRAVOLUTION’ PROJECT GETS THE GREEN LIGHT New traffic management system enables communication between cars and traffic lights to reduce ‘stop-start’ inefficiency * Audi lends its support to ‘Travolution’ project aimed at streamlining urban traffic flow through interaction between cars and traffic lights to minimise fuel-sapping ‘stop-start’ traffic * Travolution software can alert Audi drivers when a light is due to change to green, and calculate the speed that should be maintained in order to pass through in the green phase * System also reduces duration of stops by improving synchronisation and traffic light phasing across the network Frustrating, fuel-sapping stops at red traffic lights could soon be the exception rather than the rule thanks to a new initiative being championed by Audi aimed at streamlining urban traffic flow and reducing CO2 emissions. The experimental ‘Travolution’ system, developed with Audi support by traffic management experts in the brand’s German home town of Ingolstadt, will not only improve synchronisation and phasing of traffic light networks to reduce stopping times, but could also dramatically reduce the number of actual stops needed by creating a communications link between cars and the traffic light network. Communications modules built into each traffic light are able to send messages to cars in the vicinity, alerting them to the time remaining until their next green phase. The car’s onboard system is then able to calculate the speed which the driver must maintain in order to pass through the light during this green phase, and displays this via the Multi Media Interface display. A network of 46 of the ‘intelligent’ traffic lights has been installed in the centre of Ingolstadt, the software to which they are all linked optimising their phasing to bring stopping times down to a minimum, reducing fuel consumption and pollution in the process. Of the 46 light gantries, three have been upgraded to enable communication with the specially modified A5 and A6 Avant models provided by Audi as part of the 1.2-million Euro pilot project. A further 20 cars and 50 light installations are to be incorporated as the project evolves.
