Study On Bike-and-Ride System

The trip by bicycle possesses very high proportion in a lot of big cities of our country. Large amount of bicycles produce disturbances to the motor vehicles that arouses a series of problems such as traffic jams or road accidents, which brings a heavy traffic pressure to the city center. Therefore, resolving the bicycle traffic problem will be the key to promote city sustainable development. According to the real situation of our country, two schemes should be carried out together to solve this problem. First one, from the angle of traffic supply, planning and building city cycle-traffic network to regulate its traffic behavior; Another one, from the angle of traffic demand, carrying out the travel demand management (TDM) to control the long distance bicycle trips. Recent years, there have been a lot of researches on cycle-traffic network, but the research on TDM for bicycle has not been paid attention. Bike-and-Ride (B&R) is an important treatment for the urban travel demand management, which could make the bicycle become a feedering mode for mass transit to reduce the demands of long distance trips and relieve the traffic pressure of the city center. At present, the research on this aspect is so few, so this paper spreads out under this background.In the paper the developing condition and tendency of the bicycle traffic and the problems caused by bicycles are analyzed firstly. Based on above analysis, the necessity of carrying out B&R scheme is pointed out. Secondly, according to analyze the successful examples about Bike-and-Ride of foreign cities, the requisites that could carry out the B&R scheme are discussed. Comparing the relevant indexes in our cities with these requisites, the feasibility of carrying out Bike-and-Ride in our cities is put forward on condition that the public traffic would be devoted major efforts in our country.In aspect of B&R system planning, using the planning theory of foreign cities' car park-and-ride system for reference and combining with characters of the Bike-and-Ride system, the theory and method of B&R system planning is summarized.Bike-and-Ride demand predicting and bicycle parking lot location are two key parts of B&R system planning. As the aspect of demand predicting, the paper deduces the model of transfer passenger stream by the Max Use theory. Then with logically choosing feature variables, the paper establishes the BL model. According to design the SP (stated preference) questionnaire, variables datum are collected. Using above datum, the model is calibrated. Finally, one real example is used to demonstrate the whole process of the model construction and demand predicting. As the aspect of bicycle parking lot location, considering different station have different characters, the stations are divided three typical groups and the method of bicycle parking lot location is explained respectively. Additionally, The TOPSIS method is used to locate the best position from all of prepared lots at the same station entrance.
