Evaluation of Traffic Calming Techniques in Local Areas of Tehran Using Microsimulation (Case Study: Narrowing, Traffic Circle)

The increasing growth of traffic on urban roads and the excessive attention to the design of cars on roads have reduced the role of pedestrians and cyclists and increased the number of accidents on local streets. Thus, traffic engineers and urban planners can take a long step toward improving the comfort and quality of life in neighborhoods and human-centered cities by developing and designing roads based on increasing the safety of pedestrians and cyclists. Traffic calming can be set as strategies that can be effective in achieving the above goals. In this study, one local area without traffic calming is selected, and then using the PTV Vissim Microsimulation model, we evaluate narrowing and traffic circle performance on it. Simulation results show us narrwong is better than traffic circle because of greater impact on deceleration, less emission and fuel consumption.
