The urban traffic system is gradually changing from a single mode to interconnected multi-mode. In order to express the multi-mode traffic network system more accurately and meet the requirements of personal route planning and time prediction, this paper selects Oracle spatial network data model as the modeling foundation. The model takes Wuhan City as an example, and selects the road network, bus network and railway network to construct a multi-mode traffic network. Also the schedule of bus lines and subway lines is added to allow the travelers to find the quickest path to destination and to estimate the time required for the route.
