Through traffic flow research and construction environment analysis, this paper formulates ascientific and reasonable comprehensive traffic guidance reform plan, including planning bypass sections,setting up temporary traffic signs and lines, optimizing traffic signals and other measures, and carryingout monitoring and analysis on the sections where traffic guidance reform measures are implemented. Theresearch results show that the comprehensive traffic guidance reform technology effectively alleviates thetraffic pressure during the construction of urban large flow main roads, and improves the road capacityand traffic safety level. After the implementation of traffic guidance reform measures, the traffic flow ofthe bypass section changes greatly, the speed of the vehicle remains at a high level, the traffic flowdensity increases greatly, the pedestrian flow increases, the number of traffic accidents in the constructionsection decreases, and the driver’ s satisfaction increases. It shows that the bypass section plays adiversion role during the construction period,which effectively reduces the traffic burden of theconstruction section and is conducive to maintaining the stable operation of the entire regional trafficsystem.
