PURPOSE: A traffic estimation system and a traffic parameter securing method using the same are provided to calculate the full length of a vehicle, the full width of the vehicle, the overall height of the vehicle, the wheel track of the vehicle, a wheel base, the number of shafts, the overhang of the front and rear of the vehicle by combining a laser sensor, a piezo sensor, and a laser scanner. CONSTITUTION: A first piezo sensor part(100) is laid under the ground perpendicular to the driving direction of a road. A second piezo sensor part(200) is laid in parallel with the first piezo sensor part. A first laser sensor part(300) is installed to face the ground perpendicular to the driving direction. A second laser sensor part(400) is installed to face the ground perpendicular to the driving direction. A laser scanner part(500) is installed on the ground between the first piezo sensor part and the second piezo sensor part perpendicular to the driving direction. A sloped piezo sensor part(600) is laid to form a predetermined angle with the second piezo sensor part. [Reference numerals] (AA) Control part; |
