Nissan project in Beijing demonstrates Dynamic Route Guidance reduces fuel consumption and CO2 emissions
September 13, 2013
Results from Nissan’s New Traffic Information System Model Project in Beijing (earlier post) have demonstrated that Dynamic Route Guidance System (DRGS) can help alleviate traffic congestion and reduce fuel consumption. A simulation based on the project results suggested that when 10% of all traffic in Beijing used DRGS, due to reduced traffic congestion, travel speed throughout the city would increase by approximately 10% and both fuel consumption and CO2 emissions would decrease by approximately 10%.
DRDS distributes real-time traffic information from the traffic information center to onboard devices via telematics; the onboard devices show drivers the fastest route on the display. This large-scale project, involving 12,000 vehicles, is the first to demonstrate and measure traffic dispersion effects in a real setting.
