Traffic simulation system and traffic simulation program
First Claim
1. A traffic simulation system in which vehicle models, which simulate vehicles, are moved in a road system model that simulates a road system including a plurality of roads and intersections that connect the roads, the traffic simulation system comprising:
- a memory; and
a processor configured to function asan entering vehicle model presence judging unit for judging a presence or an absence of an entering vehicle model, which is a vehicle model that enters from a road in the road system model to a different road thereof via an intersection;
a calculating unit for calculating a velocity after entering the different road for the entering vehicle model that has been judged by the entering vehicle model presence judging unit to be entering the different road on a basis of a density of the vehicle models in the different road after the entering vehicle model has entered the different road; and
a setting unit that only sets the velocity calculated by the calculating unit for the entering vehicle model that has entered the different road, the setting unit does not change the velocity of other vehicle models travelling the different road ahead of the entering vehicle model in the travelling direction of the different road,an entry-origin-velocity calculating unit for calculating velocities of the vehicle models in an entry-origin road for the entering vehicle model after the entering vehicle model has entered the different road, on a basis of density of the vehicle models in the entry-origin road; and
an entry-origin-velocity setting unit for comparing the entry-origin-velocity calculated by the entry-origin-velocity calculating unit with the velocity of each of the vehicle models in the entry-origin road before the entering vehicle model has entered the different road, and for setting the velocity of each of the vehicle models in the entry-origin road after the entering vehicle model has entered the different road on the basis of a result of the comparisons.

Abstract
In a traffic simulation in which vehicle models, which simulate vehicles, are moved in a road system model including links, which simulate the smallest segment of roads divided by intersections, etc., and nodes, which simulate the intersections, turning points of the roads, etc., the presence/absence of an entering vehicle model that enters a different link from a link in the road system model via the node is judged; the velocity of the entering vehicle model after entering the different link is calculated on the basis of the density of the vehicle models in the different link after the entering vehicle model has entered the different link; and the calculated velocity is set only for the entering vehicle model that has entered the different link.
