Abstract:An analysis is made of the farerelated factors of existing lines of URT,including passenger traffic volume,ticket revenue,transportation cost and exterior benefit to make the fare of urban rail transit (URT) more reasonable.A calculation method of reasonable fare is proposed based on the idea to maximize the operating efficiency.Taking the passenger traffic and fares data of Shanghai Metro Line 5 as the case data,the method is applied to finding the reasonable fare of Line 5.The empirical study results show that although high price can increase the ticket revenue of URT,the cost per passenger and the operation cost gradually increase along the ticket price; although lower price results in the ticket revenue reduction,the unit passenger’s transportation cost and the operation cost decrease gradually and the operation efficiency increases simultaneously.Therefore,it’s proposed that mazimizing operation efficiency of URT should be set as the basis of a reasonable fare.
