Safe driving evaluation system and safe driving evaluation program
First Claim
1. A safe driving evaluation system comprising:
- a traffic signal information acquisition unit that acquires traffic signal information that indicates a display status of a traffic signal present ahead in a traveling direction of a vehicle;
a zone determination unit that determines the vehicle is within a prescribed stop supplement zone set up in front of a traffic signal installation point at which the traffic signal is installed;
a red light determination unit that determines a red light encounter, which is a state where the vehicle is within the stop supplement zone and the traffic signal information indicates that the traffic signal is red;
a stop supplement unit that performs a stop supplementary operation with respect to a driver in order to stop the vehicle at the traffic signal installation point, based on a driving operation of the vehicle during the red light encounter; and
a percentage calculation unit that calculates a stop supplement percentage as a ratio of a stop supplement frequency, which is a number of times the stop supplementary operation is performed, to a red light encounter frequency, which is the number of times the vehicle has the red light encounter.

Abstract
Safe driving evaluation systems, methods, and programs acquire traffic signal information that indicates the display status of a traffic signal present ahead in the traveling direction of a vehicle, determine the vehicle is within a prescribed stop supplement zone set up in front of the traffic signal installation point, and determine a red light encounter, which is a state where the vehicle is within the stop supplement zone and the traffic signal information indicates that the traffic signal is red. The systems, methods, and programs perform a stop supplementary operation with respect to a driver in order to stop the vehicle at the traffic signal installation point based on a driving operation of the vehicle during the red light encounter, and calculate a stop supplement percentage.
