Using the integrated passenger and vehicle simulation in evaluation of subway scheduling strategies (Case study of line one- Tehran subway)

Each variation in public transportation system has a direct effect on passengers travel time. It’s due to the integrated, direct and continuous relationship between passengers and public transportation system. In addition to, reduction in travel and waiting time for passengers will increase the use of public transport systems in a metropolitan. On the other hand, now a days, using simulation software, is one of the strongest and most acceptable tools for traffic analysis. In this study the AIMSUN (Advanced Interactive Microscopic Simulator for Urban and non-urban) and Legion software has been used for simulation of pedestrian travel time between a group of urban subway stations from Gheitarieh to Shahid Haqqani. The pedestrian flow in each station, waiting time, boarding, alight and travel time inside the vehicle has been considered too. According to the current schedule of trains, sum of the waiting time for pedestrian will be 15% more than the schedule with 5 minutes headway. Also the 4 minutes headway will cause the 45% decrease in passengers waiting time.
