Urban mobility problems demand clarity. Intersections remain the most common sites for crashes, congestion, and violations.

Q: I read yet another answer of yours about damaged sensors. Some intersections use wire loops buried in the roadway and some use cameras mounted with the traffic lights. Out of curiosity, how do they ...

Many red lights fail to detect smaller vehicles like bikes and scooters due to sensor limitations. Inductive loops, common in traffic signals, rely on sufficient metal mass to register a vehicle.

A video-detection traffic sensor system uses video cameras mounted on the mast arm of a traffic signal to "see" a vehicle approaching the intersection. When a vehicle enters the camera's "detection ...

Q: Stephen Wysong of Hemet said he has noticed over the years that most people seem unaware of the magnetic loop sensors embedded in the roadway at signaled intersections. He has seen overly cautious ...

Utilizing their SureCross Wireless Network and their M-GAGE Wireless Sensor Node, Banner Engineering Corp managed to create an efficient and reliable vehicle sensing system. The M-GAGE detects ...
