Dynamic Analysis of Parameters Affecting the Utility of Rail Transit Corridor, Case Study: Sarakhs - Bandar Abbas Corridor

In recent years، transit has been growing at a low rate in Iran; now more than 90 percent of freight transit through Iran territory is transported by road transportation; that is not in line with national transportation policies especially with the national law of fuel management in witch share of rail transportation must be at least 30% of the transit market. This small portion of rail transit is mainly because of low utility of railway corridors. In this study، the parameters affecting the utility of railway transit corridors are investigated، using a system dynamic approach and a utility function for railway transit corridors are presented. Then، using actual data of Sarakhs - Bandar Abbas rail transit route; transit demand in this corridor is simulated up to 2025. Finally، some scenarios are proposed to increasing the utility of the route. The results shows that increase in speed، reducing the train stoppages time and reducing the railway access charge، can significantly increase the route utility and consequently the demand for the route.
