Research on reasonable influence scope during road construction based on microscopic simulation
In order to determine effectively the reasonable traffic influence range during city road construction, the microscopic simulation analyses the change of intersection delay,which is caused by road construction, taking five lanes in east - west and four lanes in south - north as study object, on the conditions of different saturation based on Vissim. According to compare intersectiondelay data before and after construction,this paper determines whether the road construction produces influences on the delay of vehicle in the intersection significantly,under the condition of 95%confidence interval, which applies t test,further more decides the reasonable influence scope of road construction. Compared with the influence scope of road construction,which is determined by Webster signal cycle method, it is found that the sensitivity of the determination method,which is based on t test, for the influence scope of construction is higher,determining effectively the reasonable influence scope of road construction.
