Methods to Plan Travel Routes of Cycling Under Different Travel Demands

Currently,studies on route planning of cycling commonly contain issues as lack of considering different demands or low accuracy of solutions,which cannot satisfy the growing demands of cycling.A method to plan travel routes is developed to provide more selections of cycling routes according to various demands.Regarding trips for commuting,business,and entertainment as main purposes,through literature research,field investigation,and factor analysis,main travel demands including travel time,travel safety,and travel environment are confirmed.Then their relative influencing factors are analyzed.Data of bicycle lanes of Xicheng District in Beijing is used to process numerical calibration and algorithm description.Methods to plan travel routes under influences of a single demand or complex demands are studied respectively.Different paths are recommended according to specific travel needs.The impacts of crossing streets improve recommended precision under travel time requirements.The differences between a single demand and complex demands can provide more options for cycling.
