VEHICLE TRAFFIC CONTROL SYSTEM AND ON-VEHICLE COMMUNICATION EQUIPMENT TO BE USED FOR THE SAME

Japanese Patent JP3764712

B2

PROBLEM TO BE SOLVED: To provide a vehicle traffic control system which makes work record and operation record collectable, to which positional information and acceleration information are added at low costs even while using the existing analog tachograph and on-vehicle communication equipment to be used for the same.
SOLUTION: Analog tachograph output information or acceleration sensor output information are transmitted from the vehicle side together with positional information, time information and vehicle specification information by using the analog tachograph output information accompanied by state change of operations and works to be obtained from the analog tachograph 13 or the acceleration sensor output information accompanied by sharp acceleration change as a trigger. Then, the analog tachograph output information or the acceleration sensor output information, the positional information, time information and the vehicle specification information are received and stored on the side of the management center. Consequently, the positional information and more exact acceleration information conventionally omitted in the information to be obtained from the analog tachograph 13 are made it possible to be obtained on the side of the management center.
