Abstract

A vehicle detection system includes a transverse detector arm, two vertical detector arms, a radiation source, a plurality of transverse detectors, and a plurality of vertical detectors. The transverse detector arm may be disposed on the ground. Two vertical detector arms are disposed at both ends of the transverse detector arm. The radiation source is located above the transverse detector arm. A plurality of transverse detectors are disposed within the transverse detector arm and are laid along a length direction of the transverse detector arm for receiving ray emitted by the radiation source. The plurality of vertical detectors are symmetrically disposed on the two vertical detector arms, and each of the vertical detectors is disposed towards a center point of the radiation source for receiving ray emitted by the radiation source.
