A Multi-criteria Route Planning Approach Considering Walking Guidance
|
Abstract:
Representing the different transportation modes with independent map layers has been widely adopted in GIS for transportation related applications. Such a data model can surely meet the requirements of visualization and data management, but the independent map layers representation makes it rather difficult to generate the inherent connectivity relationships between the transportation modes, and consequently results in the multi-criteria route planning difficult to be implemented. In this paper, a logically integrated multi-modal transportation network model is firstly presented, and a technical flow for seamless transfer among transportation modes such as private driving, bus, subway, walking etc. Then a multi-criteria route planning approach considering accurate walking guidance is proposed, in which a transparent combination of transportation modes in multi-criteria route planning is realized. It is argued that the proposed approach can provide practical, feasible and personalized travel information services.
