TRAVEL TRACK GENERATION DEVICE, TRAVEL TRACK GENERATION METHOD, TRAVEL TRACK GENERATION PROGRAM AND RECORDING MEDIUM

摘要

The purpose of the present invention is to provide a travel track generation device capable of providing an optimal travel track for each travel lane. The present invention comprises: a storage unit that stores road demarcation information for demarcating a road which includes travel lanes demarcated by one or more vehicle lanes, and node information and link information for each travel lane going in the same direction and demarcated by the road demarcation information; and a determination unit that determines, on the basis of the node information and link information, track information relating to the travel route for each travel lane. The determination unit comprises: an evaluation unit that references the road demarcation information to evaluate whether there are a plurality of travel lanes in the road corresponding to the track information; and a track information correction unit that corrects the track information for each travel lane on the basis of the road demarcation information as well as the node information and link information, if the evaluation unit has evaluated that there are a plurality of travel lanes.
