Study On Layouting Algorithm Of Sharing Bike Parking Point

A series of traffic problems has brought about with the emergence of Shared bikes.At present,there is little research on the location of sharing bike parking spots in China.It has the characteristics of no pile and parking freedom for sharing bikes.Based on the domestic urban traffic problems and the status quo of research on external shared bicycles,the planning of shared bicycle parking location are researched.First of all,the importance of the development of shared bicycles in urban transportation are explained and analyzed.The function positioning of shared bicycles and the necessity of establishing shared parking spots are discussed,combining the social and economic benefits of shared bicycle systems and the development of bicycle traffic in urban public transport systems.Secondly,the factors affecting the sharing of bicycle parking are analyzed,based on the characteristics of renting.Sharing bikes is regard as a form of transportation.The stochastic utility theory are used to establish a parking demand forecasting model.A questionnaire survey are conducted on the choice of transportation modes for Beijing residents.The parameters of demand forecasting model are calibrated and the results of model parameters calibration are obtained,by analyzing the results of the questionnaire.Thirdly,the commonly used location methods in China and the characteristics of shared bicycle parking sites are analyzed.The model of parking location selection is established with the objective of minimizing the total walking distance from the starting point to the parking point.The improved genetic algorithm are used to solve the model by MATLAB programming,and the optimal solution set of Shared bicycle parking site location are obtained.Finally,the feasibility of the model method is verified by an example.The optimal scheme for site selection and layout of Shared bicycle parking spots is obtained,by calculating the instance.The results are verified by using the traditional mathematical method combined with global search to discuss and obtain the theoretical value.The opinions and suggestions of actual arrangement of parking facilities are put forward.
