Traffic Operation of Interchange and Surface Streets Improved by Access Management Techniques

To improve the traffic operation of the interchanges and surface streets,the reasons that cause traffic jam in this area are analyzed.The weaving length from the ramp terminal to the downstream intersection is insufficient is the main reason;besides,there are other reasons that make traffic operation worse,such as the bad ramp terminal layout,the lack of considerations of vicinal building access layout,the insufficiency of the vicinal intersection capacity,and etc.Through the Access Management techniques,some methods are found to relieve the jam;literature review is done about the standards of minimum distance between the ramp terminal and the closest intersection.Available way is brought forward to improve the traffic operation of interchange and surface streets.
