Abstract:
1. A route search system for receiving a provision request from a route search terminal installed on a first vehicle, to transmit route search information related to a route including at least one link, comprising: an information provision subsystem for acquiring information in response to the provision request from the route search terminal; an environmental load calculation unit for calculating, based on the information acquired by the information provision subsystem, a first environmental load generated by the first vehicle which has the route search terminal installed thereon and which runs along each link related to the information acquired by the information provision subsystem, and a second environmental load which is generated by at least one second vehicle running along each link and which is varied to account for the first vehicle traveling along each link, wherein, the environment load calculation unit sums up the first environmental load and the second environment load at each link over the route to obtain a summed up value and select the route with the smallest summed up value.
