Rail transportation as one of the major transportation modes along with significant advantages such as economic savings in fuel consumption, reduced air pollution and close to environmental standards have increased the importance of this segment of transportation and has led to the continuation and development of the rail transport sector in the country. The proper utilization of this sector as well as the necessary investment can be effective in efficient utilization of the transit situation in the rail transportation sector of the country.
The main objective of this paper is to use the panel's data econometric techniques in assessing demand for transit in the Iranian transportation sector and to estimate the demand function using the gravity model. In the estimated model, five variables: 1. The amount of transit goods carried in the rail transport sector of the country, 2. The tariff rate for transit in the rail transportation sector, 3. The transit time for transportation in the railways, Gross domestic product of Russia, India, Turkey, Kazakhstan, Turkmenistan and Uzbekistan, 5. Geographic distance between countries of Russia, India, Turkey, Kazakhstan and Turkmenistan and Uzbekistan and Iran is considered.
The results of the estimation show that the tariff variable is statistically significant and its coefficient is 0.27. Also, the time variable is also significant with a coefficient of 1.27. Both of these variables yield expectations and say that with a one percent increase in tariff rates and transit times, the transit demand in the rail transportation sector will decrease by 0.27% and 1.27%. There is a direct and significant relationship with the coefficient of 0.24 between GDP in the countries of Russia, India, Turkey, Kazakhstan, Turkmenistan and Uzbekistan and the demand for transit in the transportation sector of the country.
