1. A vehicle support information system mounted in a vehicle, the vehicle support system comprising:

  • a man-detecting unit detecting a man in a travelling direction of the vehicle;

    a vehicle-position detecting unit detecting a position of the vehicle;

    a communication unit;

    a man-position/waiting-score calculating unit determining the man detected by the man-detecting unit to be at least one potential-crossing-man who may cross the road, calculating an absolute position of the at least one potential-crossing-man as a man position using relative position information regarding the at least one potential-crossing-man relative to the vehicle and position information regarding the vehicle obtained by the vehicle-position detecting unit, measuring waiting time of the at least one potential-crossing-man to cross the road, calculating a waiting score, which is an index of waiting time for the at least one potential-crossing-man, and storing the calculated result in a man-position/waiting-score storing unit;

    a stopping-vehicle determining unit determining whether or not the vehicle should be stopped, based on the man position and the waiting score of the at least one potential-crossing-man;

    a travelling controller for stopping the vehicle when the stopping-vehicle determining unit determines that the vehicle should be stopped; and

    a man-crossing-signal display unit displaying information to inform the at least one potential-crossing-man whether or not the at least one potential-crossing-man can safely cross the road, based on an instruction of the stopping-vehicle determining unit,whereinthe man-position/waiting-score calculating unit outputs the man-position/waiting-score to the communication unit.
