Traffic Management Impact On Capacity Of Urban Road Sections

In order to solve the transportation problem which is worse to worse, many cities begin to use the advanced traffic control method, but road section capacity study has not followed, The existing calculation of capacity ignored the impact of traffic management,so the basis lacks when we do the urban road designs work, it easily caused the whole capability to be too large and the partial capability to be too small. To solve this problem, the paper firstly discuss shortcomings of the capacity calculation,then summary the impact factors of road traffic capacity, including road conditions, traffic conditions, traffic management and environmental conditions.Then try to find out the method of the computation of traffic management brings influence to the urban road capability, thus provides the reasonable selection of traffic management, in order to improve the road capacity.This article improves the present traveling capability computation which neglect the factor of traffic management, proposed that under the present traffic management level,we must consider the influencing factor of the traffic management, and gives an example to calculates its influence magnitude. The 2nd,3rd chapters of the paper firstly analyze some concepts for capability related and the computational method, has made the upholstery for follows example road section traveling capability computation. The 4th chapter has analyzed the road section traffic management mathod and proposed the traffic survey plan. The 5th chapter carries on to analyzes the present situation road section capability and calculates the influencing factor the size of traffic management the present situation, latter,in order to compare,the paper carries on the analysis of the capability and the traffic control influencing factor after implementing the suggestion. The 6th chapter carries out the Traffic Emulation to examine the example analysis.
