Research On The Directional Method Of One-way Road In The City

With the fast development of the economy of our country, the promotion of the urbanization process, urban population is increasing constantly, the owning amount of motor vehicle is increasing doubly. The city traffic question becomes the bottleneck restraining the city from developing further. In order to solve the problem that urban traffic jam , traffic pressure are big, the text directs against the existing road networks of the city, put forward and adopt the urban road to realize the method of the one-way traffic alleviates the traffic pressure, by analysed that implements the necessity , rationality , validity of the one-way traffic; Through implementing the road under two kinds of situations of two-way traffic and one-way traffic, the difference of the complexity of its crossing, the highway section is different from traffic capacity of the crossing, point out the urban road implements the superiority and feasibility of the one-way traffic The research is in carrying on one-way traffic design of urban road, how to carry on rational orientation to the highway section, make road this among the network , crossing complexity reduce , vehicle pass through speed increases, the traffic capacity of the road improves, the vehicle makes a detour in less distances. Structure model by method through mathematics, research model ask and solve the method and directional step of road. To urban road picture that network form, is it is it talk about relevant knowledge to pursue to utilize, construct Hamildon return circuit, look for the minimum return circuit , utilize BFS law and construct the law of enclosing to carry on orientation to the side in all pictures, thus got orientation of purely one-way road to pursue .Improve its one-way network finally, shorten the vehicle and make a detour in the distance , design the comparatively rational one-way road network. In order to book the traffic result backward and appraise one-way to the road further, this literary grace appraises the result with the analytic approach of the level, structure the index system rationally, have fixed the weight through a large amount of materials and practice. Regard Changsha as the instance , has carried on the directional design of the road , and appraise traffic result to it.
