Transit means moving goods or passengers through a country which is neither their origin, nor destination. It is one of the most important revenue sources in many countries in the world. Iran is located on the north- south and east- west railway transit corridor. Bandar Abbas- Sarakhs railway corridor is the most important railway corridor in Iran.
Currently in Iran, about 10% of freight transit is done through rail transportation which is not in line with the transportation policies that based on them about 30% of freight transit should be done through rail transportation. However, Iran's railway network is very wide and we can increase the share of railway in freight transit. Therefore it is important to recognize the effective factors which increase the share of rail transit.
The purpose of this research is recognizing the factors increasing the utility of railway transit corridors and improving the competitive position of railway in freight transit. So the concepts of utility and transit are described in first place, then the factors affecting the utility of railway transit corridors from the perspective of the owner of goods are determined by making a literature review and investigating the opinions of experts. These factors include transportation cost, commercial speed, reliability, safety, the system of tracing wagons and service frequency. Then a utility function for Bandar Abbas- Sarakhs corridor is presented based on the mentioned factors. At last, a dynamic model to evaluate the utility of the mentioned corridor is developed and after verifying the validation of it, the model is simulated by vensim PLE software for 20 years.
The results of simulation show that simultaneous improvement in reliability, the system of tracing wagons and commercial speed and also giving discount on the cost of transportation according to the demand of the owner of goods can increase the utility of Bandar Abbas- Sarakhs corridor.
