It is an integrated transportation management system that effectively integrates advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground transportation management system. It is a comprehensive transportation management system that plays a role in a large range and in all directions, and is real-time, accurate and efficient.

[0003] In related technologies, an electronic traffic checkpoint includes surveillance cameras installed on electric poles beside traffic lanes. The monitoring points are distributed at road intersections and key sections where traffic and pedestrian flows are relatively concentrated. The road traffic conditions are uploaded to the road monitoring command center in real time through image transmission channels. The center's on-duty personnel can use this to promptly understand the road conditions in each area, so as to adjust the vehicle flow at each intersection and ensure smooth traffic.
