The Cost And Benefits Analysis Of Urban Bike-sharing Service System

The public bicycle service system present rapid develop ment trend in the world, and it’s even more amazing in C hina, this is mainly because we adopts the model of government- leading, the government invested huge funds to the construction of system,at the same time pay operators high subsidies to maintain ope ration, and it causes the consensus of "public bicycle is too expensive" in society, so the article studied the cost and benefit of the public bicycle.First, the article established the Binomial- Logit choice model based on the travel chain, the results show that there are five factors affect the behavior of the travel cho-ice, and travelers are more sensitive to the convenience of bicycle, and by improving the public bicycle site coverage can effectively improve the usage of public bicycle.Secondly, in the case of a limited sample data, the article predicts the usage of public bicycle by establishing GM(1,1) model and improved model, and use the MATLAB to calculate the models, the results show that GM(1,1) model has a better effect.Thirdly, the article analyzed the composition of whole life cycle of public bicycle service system, and present calculation modles which are maneuverable and easy to c alculate the cost and benefit.Finally, the article applied theory and methods to calculate the Xi’an public bicycl e service system’s cost and benefit. The results showed that operational efficiency is much higher than the cost of system, and confirms the value of public bicycle service system.
