Optimization and restructuring of the road resource with construction materials based on road environment Xiaodong Tan1, a, Xiaoyi Yang2, b , Piwei Song3,c 1,2,3 School of Mechanical Engineering, Dalian Jiaotong University, China a 416808171@qq.com, byangxiaoyi0826@163.com, c775704875@qq.com Keyword: traffic congestion,road occupation rate,restructuring Abstract: For most of the cities will appear traffic congestion on the work the peak of the big gap in both directions of traffic between the same road sections in china, comparative analysis of the collected traffic flow on urban road sections on the flow and the value of road occupation rate and statistical derivation.Proposed the concept of restructuring on the road environment.
For most of our cities will appear traffic congestion on the work the peak of the big gap in both directions of traffic between the same road sections, by taking advantage of the road reorganization of resources and the idea of network topology on the road environment to restructuring,to exist road resources to optimal control theory to improve road traffic congestion phenomenon and improve the utilization rate of the road to save construction materials .[1] Data acquisition of traffic conditions characteristic In this paper, use the fixed traffic detectors to acquire the parameters of the road.Traveling in both directions on the section of the road install a detector respectively.
Fig. 2 The original road traffic flow Fig.3 Reorganization of the road traffic flow Conclusion This paper presents a new concept on the road to restructuring with construction materials based on road environment, the rule of reorganization discriminant based on the specific state of the road, theoretically improve the resource utilization of the road, while alleviating the crowded state of rush hour on the road.

Principle A lot of evidences [4, 5] about the hot deformation of different metals and materials suggested that the power law and the exponential relationship correlate strain rate with steady state flow stress σ of the materials at low and high stress levels as follows, respectively low stress : = A 1σ n1 (1) high stress: = A 2exp (βσ) (2) where n1 and β are temperature-independent constants.
