PROBLEM TO BE SOLVED: To provide a probe car system which efficiently collects measurement data from an on-vehicle FCD machine by using a beacon. SOLUTION: A machine 121 mounted on a probe car which selects the combination information (1) of measurement information measured during running of the car and road section reference data representing a measurement section or the sole information (3) of the measurement information and uploads the selected one and a center device which collects the measurement information from the machine 121 mounted on the probe car through the beacon 123 are provided to the beacon 123. In this system, when the probe car 121 runs on a road provided with the beacons 122 and 123, only the measurement information is transmitted in case that the car passes below the beacon 123 on the downstream side, and accordingly the data quantity of the measurement information is increased, and detailed measurement information is transmitted. When the probe car 121 runs on a detour, the locus of running of the car on the detour and the measurement information are uploaded to the beacon 123 on the downstream side, and accordingly the center device makes use of them as the measurement information of the detour.
