Prioritizing Routing Factors Affecting UrbanTrain Lines

Today, traffic and traffic congestion in big cities has become a problem for most countries. Due to rapid population growth and increasing welfare indicators and vehicle ownership rates, and, on the other hand, urban traffic space limitations, traffic problems in most over-populated cities exist or are emerging. Public transport systems play an important role in reducing traffic. One of these methods includes urban railway lines which transport a large number of passengers daily. Thus, pathways and their impacts on traffic of every area are of significant importance. Accordingly in this paper, first, indicators affecting the routing of lines and the amount of traffic flow are explained, then, the importance of each parameter has been determined using AHP method. Results indicate that geographic factors with 63.7% stand first, transport factors with 15.3% stand second, social factors with 11.4% stand third, engineering factors with 6% stand fourth and economic factors with 3.6% are in the final stage, which shows that the influence of geographic factors on the amount of traffic in routing urban train rail way sis the greatest.
