Claims (1)

[Scope of Utility Model Registration Claim] A system that displays passing zones based on the distance between each intersection, the signal cycle length, the ratio of green light time and red light time of traffic signals, and the design speed, and the signal display timing and design speed. A system diagram creating means for creating a diagram, and calculating and storing actual distance data, speed data, time data, and intersection position data from the number of rotations of a car's tires, the outer circumference of the tires, the travel time, and the intersection passing signal. A driving trajectory that compares the stored intersection position data with the intersection position in the system diagram, corrects errors in the distance data, and creates an actual driving trajectory from the corrected distance data and time data. A driving situation evaluation device comprising: a creation means; and a writing means for writing the created actual travel locus and speed data into a system diagram.
