    • PROBLEM TO BE SOLVED: To provide a simulator capable of quantitatively evaluating the introduction effect of a front lamp system.SOLUTION: A simulator capable of executing a simulation of simulating actual traffic flow for a prescribed period set beforehand includes a traffic environment reproduction part, a driver simulation part, and a vehicle reproduction part. The traffic environment reproduction part allocates vehicle characteristics so that a prescribed proportion of vehicles are loaded with the front lamp system. In the case that simulation time is nighttime, when there is an oncoming car to one vehicle which appears in a road traffic environment, the driver simulation part calculates equivalent veiling luminance of a driver of the one vehicle in consideration of a light distribution state of a front lamp of the oncoming vehicle, and determines whether or not a driver is capable of identifying a pedestrian using the equivalent veiling luminance.
