1. A driving environment evaluation system, comprising:
- at least one processor comprising;
a driving environment information acquisition section, which acquires driving environment information, which is information on a driving environment of a movable body from an image taken by a camera mounted on the movable body or from an object detected by a millimeter-wave radar;
a position acquisition section, which acquires a position where the driving environment information is acquired; and
a driving environment evaluation section, which quantitatively evaluates ease of traveling of a driving environment of the movable body based on an analysis of driving environment information acquired by the driving environment information acquisition section,wherein the driving environment evaluation section is configured to evaluate the ease of traveling of the driving environment of the movable body through an analysis of an element of the acquired driving environment information, which changes dynamically at each position, whereinthe driving environment evaluation section evaluates the driving environment through process steps of;
a) calculating a basic score by a quantitative evaluation of structural factors of a road to be evaluated, based on road map data containing information on a road map registered therein;
b) quantifying minus factors that reduce the ease of traveling based on an analysis of a road environment, a traffic condition and a weather condition of a driving environment indicated by the driving environment information; and
c) calculating an index that quantitatively evaluates the ease of traveling by subtracting quantified values of the minus factors that reduce the ease of traveling from the basic score.
