Study On Organization And Capacity Of Waiting-area For Through Vehicles At Grade Intersection

At-grade intersections were the capacity bottlenecks of road, and traffic congestion problems becomed to a very severe level. Traffic congestion has been a point to a line, from local to large-scale spread. Urban traffic problems not only affected the city's efficiency and quality of life and brought a series of social problems such as environmental problems, which has become one of the important factors for the city's economic development constraints. Therefore, in solving the urban traffic congestion and improving the overall network capacity under the premise of how to improve the intersection capacity and operating efficiency will be extremely important. To address the widespread problem of traffic jams, this article make use of the intersection region to organize free transport, the use of low-cost, the efficiency of traffic organization and traffic control methods to solve the problem of traffic congestion, improve the operation of road vehicles.In this paper, it discussed the grade-intersection which was setting waiting-area for through vehicles of the channelization design, organization and capacity. Paper introduced the research background, research and study at home and abroad and the technology methods. And it introduced the channelization of the definition of traffic and channelization design some method of signal cross-plane T-junction and intersection signal design method of channelization, in the conventional design method of lines to be made by the first stop line post-design method. Traffic organization, introduced the concept of optimization and some way of thinking, through secondary to pedestrians crossing the street and started the second vehicle design, gives the signal cross-plane T-junction and traffic signal intersection the methods proposed straight Region to be Region and turn left at the same time to be applied to planar cross a signalized intersection approach organizations. At this stage by introducing the use of domestic regular intersection capacity calculation method of calculation focuses on the norms of the law of the city formula, through the static and dynamic analysis of two methods, derived from the straight line area to be increased on the signalized intersection the formula for calculating the capacity, and to be calculated by simulating the application of Region provides a theoretical support. Survey data combined with the subject of the Dong Road, Wuhan City Road and Friendship Road intersection and parrots and Hanyang Avenue question by setting Region, drainage and intersection, and optimize the traffic organization and effective to improve the traffic capacity of intersections, vehicle in the intersection to reduce delays Department.The last, sum-up the work, in which the primary work, the final conclusion, the significance and the applied fields of this dissertation are briefly depicted, the subsequent work need to be accomplished is also conceived.
