PROBLEM TO BE SOLVED: To provide an accident spot identification device capable of responding to a change in predetermined information and accurately identifying an accident spot, should such change occur.SOLUTION: An accident spot identification device includes storage means, identification means, obtainment means, first calculation means, determination means, second calculation means, third calculation means and first correction means. The determination means compares a DC resistance measurement value obtained by the obtainment means and a DC resistance total value calculated by the first calculation means, and determines whether the DC resistance measurement value is larger than the DC resistance total value. The third calculation means divides a difference between the DC resistance measurement value calculated by the second calculation means and the DC resistance total value by the number of connecting points interconnecting individual devices, to thereby calculate a contact resistance value indicating a value of DC resistance at each of the connecting points. The first correction means corrects an error in the stored information by using the calculated contact resistance value. |
