Abstract:
The average delay time of the nodes (intersections and roundabouts) in dynamic traffic flow is one of the major key elements of predicting travel time. On the contrary, determining and updating the average delay time of the dynamic traffic flow in regard to calculation of travel time has received very limited attention, even though most of the current techniques use the historical data for their static calculations. Average delay time of the intersections and roundabouts needs to be updated due to the changing of the dynamic traffic conditions.The aim of this study is to propose a method which leads us to finda formula for average dynamic delay time of intersections and roundabouts. The proposed method calculates the dynamic average delay time by using the output of the SIDRA intersection software (micro simulation transportation one) and finds the relationship among the effective parameters on average delay time by using optimized GMDH software. Hence, for evaluating the accuracy of our suggested formula we compare the amount of average delay time which obtain from Highway Capacity Manual (HCM) instruction as one of the acceptable methods among the other manuals and the real one and our purposed formula. Numerical analysis by SPSS also indicates that the solution approach can be applied in practice in any size networks
