Evaluation and Improvement of Carrying Capacity of a Traffic System

Abstract

This paper proposes indicators to evaluate the operating conditions of the traffic system. Through the evaluation, find the key problem nodes in traffic system and apply specific improvement measures to improve them. For evaluation of traffic capacity, use “3 steps method” to forecast the traffic volume in the traffic system which means based on current data multiply the nature increase coefficient to forecast the nature increase of the traffic volume, then add the new traffic volume created by new buildings to get the total traffic volume in future. Then, use specific indicators to evaluate the traffic conditions and find bottlenecks in the traffic system. After that, improve the capacity of the traffic system by improve the capacity of bottlenecks. Finally, evaluate the traffic condition again and test the improvement effect by comparison.
