THE STUDY OF A METHOD FOR SMOOTHING TRAFFIC FLOW BY RAMP CLOSURE ON URBAN EXPRESSWAYS

The Metropolitan Expressway has a length of 263.4 km and an average of 1.16 million vehicles use it per day. However, traffic congestion is becoming frequent in the Inner Circular Route and other routes radiating from it, because the network is unfinished. The Metropolitan Expressway Public Corporation has done traffic management as a way of reducing traffic congestion and smoothing traffic flow with the cooperation of the police. However, the traffic condition has been changing due to the expansion of the network, increase in traffic, and so forth. Also, because the effect of the current technique for smoothing traffic flow has decreased, a review of the current technique is needed. Therefore, a new technique was examined in this study which involves closing entrances which normally were never closed, so special attention was placed on Hakozaki Rotary, one of the merging sections of outbound Route 6, which is one of the bottlenecks of the Inner Circular Route. A trial was made by closing the Hakozaki and Hamacho entrances, and the effect of it in the smoothing of traffic flow at the expressway and negative impact on the surface streets near the entrances were analyzed.
