A traffic flow simulator configured to simulate a traffic flow of a plurality of simulation vehicles generated in a road network. The traffic flow simulator includes: a route selection unit configured to select a route for each of a plurality of the simulation vehicles in accordance with a predetermined route selection model; and an index calculation unit configured to calculate a traffic evaluation index of the road network by causing each of a plurality of the simulation vehicles to move on the road network in accordance with the route. The route selection unit records, into a storage unit, a first route selected during execution of a first mode below and a second route selected during execution of a second mode below, the first and second mode being a work mode in which the traffic flow is simulated under a first and second setting condition.

Traffic flow simulator, simulation method of traffic flow, and computer program

This traffic simulator is provided with a simulator engine unit for performing computation on the basis of a formula representing a movement model for a vehicle, a traffic volume calculation unit for calculating a generated traffic volume and a removed traffic volume on the basis of a given OD traffic volume, an estimated congestion length calculation unit for calculating (estimating) an estimated congestion length for each link on the basis of the calculated traffic volume thereof, an origin and destination generation unit for generating an origin traffic volume and an destination traffic volume to adjust the estimated congestion length on the basis of the difference between the estimated congestion length and the measured congestion length, a storage unit for storing predetermined information, and an evaluation condition setting unit for setting evaluation conditions for evaluating the traffic various quantities metrics.
