Abstract


Of highway built in the 1990s , has been close to or more than the design life . The highway traffic has exceeded the designed capacity , traffic congestion or subgrade and pavement damage . Therefore , on the highway expansion to continue services for economic and social activities , is the main task and pressing issues of China 's highway construction in the current and future period . During the renovation and expansion , traffic organization is neither excessive reduction of the construction area traffic capacity , and protect the vehicle safe passage Highway science and technology workers concerns and the need to solve the key technical problems . In this paper, based on the analysis of relevant research , analyze the characteristics and applicability of various renovation and expansion mode , and the renovation and expansion construction area to define and control zoning , using statistical analysis , traffic flow characteristics of traffic engineering principles in the construction area study . In the analysis of traffic flow organization influencing factors on the basis of proposed road network based on the point , line, surface three levels of organization method of traffic flow and construction zone traffic parameter design method , relying on engineering targeted traffic for renovation and expansion construction area stream organization scheme . To VISSIM simulation platform , the establishment of the road network , the sections of the simulation model , combined with the actual traffic flow data simulation and modify the programs of the organization of traffic flow . Finally , optimize traffic flow organization . The research results have reference value in the construction area traffic flow organization , traffic safety is of great significance to improve the capacity of relying construction area sections to protect .
