An Optimized Design Scheme for Roundabout Traffic Management

Roundabouts have since become increasingly common. Statistically, roundabouts are safer for drivers and pedestrians than both traffic circles and traditional intersections. However, in the actual life, now roundabout faces the challenge that the traffic flow exceeds the limit. In order to decrease the construction cost and maximize the benefits, in accordance with the analysis of the roundabout capacity and traffic signal control, the author put forward a self-suitable red light adjustment scheme based on BP neural network. At last, integrating the roundabout traffic management system actually investigated, selecting the data to do the test to prove the validity of the mentioned scheme.
