ROADSIDE PORTION TRAFFIC AMOUNT CALCULATION DEVICE AND ROADSIDE PORTION TRAFFIC AMOUNT CALCULATION METHOD

摘要

A roadside portion traffic amount calculation device is provided with a positional information acquisition unit which acquires positional information; a positional information distribution determination unit which refers to road information stored in a road information storage unit and determines a passage roadside portion which is a roadside portion where user locations exist, on the basis of the positional relationship between the user location indicated by the positional information and the road, with respect to each piece of the positional information; a positional information summarizing unit which counts, for each roadside portion, the number of the pieces of the positional information of which determination regarding the passage roadside is performed by the positional information distribution determination unit, and summarizes the roadside traffic amount which is a user traffic amount per roadside portion; and a processing result output unit which outputs the roadside traffic amount summarized by the positional information summarizing unit. Thereby, the traffic amount of pedestrians at each roadside can be obtained.
