In recent years, highway construction and development at the same time , there are also many problems. One hand, part of the highway can not meet the growing needs of the traffic to its change expansion ; highway the other hand, the need for routine maintenance and clean-up. Therefore , the construction maintenance operations become more frequent. Transportation organizations need in order to ensure the safety of the construction workers and the safe operation of the vehicle , and to improve the service level of the highway construction section , this play better highway during construction of a highway construction zone . Using the Vissim simulation software program of highway traffic organization through the results of analysis and evaluation , which highway construction zone traffic organization programs to optimize . From the construction zone traffic characteristics , traffic organization plan design , highway construction zone traffic simulation and evaluation system to study four aspects of optimization and simulation evaluation on highway construction zone traffic organization programs . First, the introduction of highway construction form of different construction , and analysis of the construction zone traffic characteristics , vehicle operating characteristics , as well as roads , traffic flow characteristics . Secondly , according to the principles of the Organization of the highway construction zone traffic , respectively, from the length of the work area , the speed limit , and traffic safety and management facilities set three aspects on highway construction zone traffic organization design and traffic simulation system processes , depending on the traffic organization plan for the establishment of a corresponding simulation model , establish a reasonable highway construction zone traffic organization plan evaluation system , and select the evaluation indexes . Finally, the combination of specific instances of using Vissim to simulate the traffic organization plan , analysis and evaluation of the programs , compared to the level of service of the construction area in the simulation of different options , in order to determine the optimal solution .
