TRAFFIC EVALUATION APPARATUS, COMPUTER PROGRAM, TRAFFIC EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a traffic evaluation apparatus, a computer program, and a traffic evaluation method which can make a comparison of a traffic evaluation index before and after evaluation conditioning.

SOLUTION: A traffic simulator 10 comprises: a simulator engine unit 11 which performs computations on the basis of a calculation expression indicating a moving model of vehicles; a traffic volume calculation unit 12 which calculates an occurring traffic volume and an extinguishing traffic volume on the basis of a given OD traffic volume; an estimated congestion length calculation unit 13 which calculates (estimates) an estimated congestion length in each link on the basis of the calculated traffic volume; a start point/end point generation unit 14 which generates a start point traffic volume and an end point traffic volume for adjusting the estimated congestion length, on the basis of a difference between the estimated congestion length and an actually measured congestion length; a storage unit 18 which stores predetermined information; and an evaluation condition setting unit 19 which sets evaluation conditions for evaluating a traffic state quantity.
