The Traffic Safely Control Technology Research Of Mountain City Plane Intersection

Plane intersection is the city road network capacity and the difficulty of traffic safety. Coming from different directions of traffic flow in here continually cross, rivers, shunt, plane intersection place, the traffic situation is very complicated, which is produced traffic conflict and traffic accident multiple point, therefore in the intersection safety status for the whole city traffic safety level has a very important impact. Especially for mountain city character, plane intersection design is usually by topography condition limit, this plane intersection traffic safety guarantee in bring the great difficulty. Therefore, the mountain city road plane intersection geometric conditions, factors such as road conditions on traffic safety accident and conflict characteristic research for the full use of intersection place time and space resources, alleviate the growing urban traffic pressure, improving the traffic and safety of the system capacity has an important role.The paper first introduces the mountain city road plane intersection of research methods and achievements, and through introducing mountain urban road traffic safety situation, current situation and existing problems, and application of the mechanism of accident theory to analyze the traffic the cause of the accident, it is the result of many factors.Secondly, through the mountain city complex geometry, mark line, pavement quality factors on the capac ity of intersections, carried on the detailed analysis of the safety, this paper mainly analyzes the plane intersection place motor vehicle and motor vehicle, vehicle and pedestrian traffic conflict characteristics.Again, based on mountain urban transportation mouth safety factor analysis, using the traffic conflict technology theory, based on the traffic ChongTuDian, traffic flow, and other influence factors for consideration, respectively get ChongTuDian potential risk model, traffic flow influence model and other factors correction model and will last three model integration, the establishment of intersection safety evaluation total model.Finally, in order to reduce intersection in traffic accidents and improve the urban overall traffic safety level for the purpose, from the canalization and other intersection safety facilities, this paper puts forward the mountain city intersection safety improvement measures.
