Optimization Research on the Fiscal Subsidy Mode for Intercity Railway Based on Environmental Cost

The characteristics of Intercity Railway include safety, reliability, low carbon and environmental protection, therefore the government's fiscal subsidy for intercity railway is beneficial to reduce energy consumption and pollution emission, and further to realize the public welfare goal of reducing the environmental cost of transportation system. In this paper, firstly the authors take the environmental cost of traffic system, enterprise benefits of intercity railway and intercity passenger demand into consideration, and establish a bi-level programming model, which the decision-level aims at the minimum environmental cost and the maximum enterprise benefits and the execution-level aims at passenger flow assignment. Then they use genetic algorithm to figure out the optimal operating frequency in the bi-level programming. Following that they propose the fiscal subsidy modes for intercity railway and calculate the optimal operating frequency of intercity trains under the different fare subsidy rate. Lastly the authors analyze the results and obtain the optimal fiscal subsidy model for intercity railway with the comparison of the total expenditures of government subsidies. The model is verified by an example of case in the end and the research of this paper provides a theoretical reference for the government fiscal subsidy policy.
