查询词典 Ring-fence

Taking the ring intersection at Bell Tower of Xi′an as an example,optimized signal timing scheme is proposed with the help of traffic simulation software VISSIM,and then the scheme is evaluated. The results of analysis indicate the scheme can reduce the vehicle delay and improve the traffic capacity of the ring intersection effectively,which validate that applying microcosmic simulation software VISSIM in signal timing of ring intersection is feasible.
