Abstract: According to OD traffic volume of the peripheral node of the construction area, with the method of distribution of capacity constraint, we can calculate the surrounding traffic volume after the occupation. Referring to the threshold values of traffic impact degree classification, we can determine the degree and scope of surrounding roads by presence construction. In the construction-influencing zone, based on the status quo of traffic and road conditions, with constrain on the reliabilities of the path travel time, we can calculate the minimum dredging traffic and surplus bearing capacity of road. We can expand the scope of guidance from the construction section step by step until meeting the constraints of travel time reliability. At last the traffic flow of the construction roads can be controlled in the acceptable range. This can reduce influence on the presence construction to traffic.
