Abstract

In the urban transportation network as the traffic signals went green at the intersection of the upper hand, a group of vehi-cles move together and arrive at the next intersection, almost in group. If, at the same time as the group arrives, the signal of the corresponding route at this intersection is green, the total delay and stop of the vehicles will be significantly reduced and the intersection efficiency will increase significantly. The same strategy was implemented on the political vehicles in the study, so that the delay and stop time for them could be reduced. In this study, part of the political vehicle route from Saad-Abad Palace to the presidential office on Pasteur Street is considered. In this study, various strategies were developed to prioritize the vehicles in the Aimsun simulator software. Then, to detect the arrival of these vehicles to the intersection, two identifiers were embedded, one before the intersection and the other after it was installed. Among the results of this study are the following: There is an average increase in the average travel time for a scenario with an extra green time of 10 se-conds and 15 seconds. The average delay time was 7 seconds for the additional green time scenario of 10 seconds and the average delay of 6 seconds for the sub-scenario of 15 seconds increased. The average number of stops per vehicle in-creased by 0.1 stops per vehicle in both cases.
