Summary:PURPOSE: A system and a method for measuring weight of a traveling vehicle in consideration of change of speed and lanes are provided to accurately measure a weight of a vehicle even though the centroid of the vehicle is inclined toward the left side or right side because a weight value measured by a piezo-sensor is revised according to an acceleration value. CONSTITUTION: A system for measuring weight of a traveling vehicle in consideration of change of speed and lanes comprises three piezo sensor groups(P10,P20,P30) arranged lengthways side by side at constant intervals, a pair of loop sensor groups(L10,L20) arranged in the outer side around the piezo-sensor groups at constant intervals, a pair of the piezo sensor groups(P40,P50) arranged in the outer side of the loop sensor groups at constant intervals, a pair of the loop sensor groups(L30,L40) arranged in the outer side of the piezo sensor groups at constant intervals, and a server. The server receives information from loop sensor groups and calculates a weight of a vehicle by multiplying left and right bias correction coefficients by the weight of the left and right wheels.
