PTV manages Strasbourg’s traffic flow to improve air quality

PTV Group's signal control system has helped Strasbourg’s Eurométropole reduce nitrogen oxide emissions by 8% and particulate matter by 9% in a project which set out to slash emissions by decreasing stop-and-go traffic along one of the city’s main arterial roads. The simulation also cut vehicle stops by 9%. Called PTV Epics, the software tool controlled the waiting times for all road users at the traffic lights, reducing 85% of all cases to 45 seconds, which would otherwise only apply to 35% of road

3264 PTV Group's signal control system has helped Strasbourg’s Eurométropole reduce nitrogen oxide emissions by 8% and particulate matter by 9% in a project which set out to slash emissions by decreasing stop-and-go traffic along one of the city’s main arterial roads. The simulation also cut vehicle stops by 9%.


Called PTV Epics, the software tool controlled the waiting times for all road users at the traffic lights, reducing 85% of all cases to 45 seconds, which would otherwise only apply to 35% of road users.

Frédéric Reutenauer, project officer and vice president project management & services at PTV Group, said: “PTV software helps optimize signal control programs in order to minimize waiting times at traffic lights and thus reduce the number of stop-and-go waves. We used the traffic simulation software PTV Vissim to visualize the effect on traffic by analysing the traffic flow at six signalized intersections of Avenue de Colmar located south of Strasbourg.”

    Alan Dron looks at changes in bus propulsion as cities look to improve air quality and seek to reduce maintenance costs. Despite the ending of various incentives to adopt alternative fuels, the introduction of electric buses by US transit authorities is picking up speed as performance improves, costs drop and air quality considerations become increasingly significant. More US bus manufacturers are introducing zero-emission models and some recent contracts will see many more passengers getting their first

    Europe’s leading traffic police chiefs are struggling with the challenge of how best to manage the region’s road network in an era of austerity. Things are changing fast, and not for the better, reports Geoff Hadwick. Europe’s road safety record is under threat. Police budgets are being slashed, staff numbers are falling and a long-term trend towards ever-fewer road deaths has ground to a halt. The line on the graph has flat-lined. Does Europe’s road network face a far more dangerous future? Lower and
