Yunex Traffic is installing a traffic light phase assistant in Darmstadt, Germany, which generates real-time traffic data to create a green wave for traffic flow. Yunex's assistant, which will be incorporated into the city's DAnalytics project, will inform road users, via the company's recently launched Signal2X smartphone app, about the optimal travel speed they should maintain to ride the green wave. A so-called green wave occurs when a driver travelling at a specific speed along an urban road sees, in the distance, a progressive cascading of green lights at intersections. The idea is to coordinate the traffic lights to allow for continuous traffic flow over several intersections in one main direction without a driver having to stop and wait at red lights. By not stopping, there is a reduction in noise, vehicle emissions and energy use which creates a healthier environment along the route and nearby city areas. |
