Abstract：With rapid economic development and accelerated urban expansion in Lhasa,both numbers of pedestri-ans and vehicles have been increasing,leading to congestion at certain intersections,which has disrupted pedestrian travel and vehicle operation,and affected social economic development.Therefore,relevant optimization research is needed.In response to unreasonable road design and signal timing,this paper has selected the intersection of Jiangsu East Road and Linju North Road in Lhasa as the research object.The traffic flow of the corresponding road entrance direction is obtained by manual counting as the basic data.The current intersection simulation data is obtained by us-ing VISSIM and SYNCHRO simulation software.Based on the current intersection situation,corresponding chan-nelization and signal timing optimization schemes are proposed,which are analyzed and verified by simulation soft-ware.Through the comparison of data before and after optimization,the optimization schemes have effectively im-proved the operational efficiency of road intersections and reduced the conflicts between pedestrians and vehicles,providing reference for optimization of other intersections in Lhasa.
