Advanced multi-modal routing approach for pedestrians

Multiple transportation modes should be considered in advanced traveler information systems. This paper presents an advanced multi-modal route planning approach considering accurate walking guidance with multi-criteria evaluation. Walking has been usually ignored in current traveler information services. A walkway network is established automatically with spatial manipulation and semantic analysis on road network and pedestrian facilities, which further used for building logical integrated multi-modal network. Then a mode priority based multi-modal, multi-criteria dynamic route planning approach is proposed. A user-free combination of transportation modes with user specified route criteria is implemented to provide more practical, feasible and personalized solutions on route planning. With absorbing dynamitic traffic information into the route planning algorithm, the characteristic of dynamic traffic change has been considered in our research.
