Freeway Rebuilding has become the current road construction hot spots, the highway during the renovation and expansion takes the original lane, would inevitably lead to the original crossings change in a short period of time, resulting in a sharp decline in capacity. Construction zone traffic organization Freeway expansion of the main part of this paper, the renovation and expansion highway renovation and expansion project construction period influencing factors, re-analysis of the renovation and expansion of expressway traffic organization Freeway Rebuilding traffic organization programs determine provide ideas. Papers on the basis of analysis of the research status at home and abroad, the main content of this paper. Segment traffic flow characteristics influence factors and construction of the highway during the renovation and expansion project, followed by a highway expansion project by the analysis, summarized and summed up the advantages and disadvantages of various expansion treasure Freeway and west expansion mode choice example. Secondly, highway expansion to the center, based on the analysis of its sphere of influence, the shunt from the external and internal traffic organization analysis. Follow the principle of traffic organization under the premise, first introduced the external traffic diversion organizational design, analysis freeway shunt models, diversion road network as well as induction, shunt and control point set for analysis to determine the diversion program, at the same time west treasure Freeway Rebuilding external shunt, for example, be applied. Finally, the West highway expansion construction zone traffic organization plan to the organization, and the renovation and expansion construction zone traffic organization project evaluation. Freeway Rebuilding internal traffic organization design, based on the nature of the works and the construction characteristics, the internal organization of the design is divided into four construction phases: 1, roadbed construction early; roadbed construction late; 3, road construction period; 4, traffic engineering and facilities and landscape green construction period along and west of highway expansion the internal organization of design and planning, for example on the main line sections Interchange section of the overpass sections of renovation and expansion construction organization. Finally, the evaluation of the traffic organization plan from the start, building evaluation index system, after the screening to determine the standard, and to determine the dynamic comprehensive evaluation method to analyze the results of the evaluation, and dynamic comprehensive evaluation method to evaluate the case, evaluation by verified This thesis is about the correctness of the design and evaluation of highway construction traffic organization plan.
