Welcome to the Traffic Management Channel, a special section that provides the user an in-depth look at the multiple aspects of traffic management — straight from sources of ROADS & BRIDGES magazine and our Transportation Management & Engineering supplement.

 

Topics covered include intelligent transportation systems, traffic signals, traffic monitoring, intersection safety, traffic design software, electronic tolling and congestion pricing.

All-Electronic Tolling-1

Using a system that complies with open standards is essential for systems and data to be interoperable.

,

Whether in a HOT lane or a managed lane, AET provides a complete management platform and real-time diagnostics.

,

OCR software must be able to take into account other distinguishing characteristics besides a license plate.

,

Identifying a car and mailing a bill to the owner may not always be worth the value of an inexpensive toll.

autonomous vehicles 1

Driverless-vehicle innovators are not waiting for transportation authorities to build “smart” highway infrastructure.

,

GM’s Super Cruise does adaptive cruise control and lane centering, using cameras and sensors to automatically steer and brake.

,

By shifting vehicle control over to electronics, driverless-vehicle technology destabilizes the legal regime.

,

The deployment of driverless-vehicle technology will require highway authorities to understand how driverless vehicles \"see.\"
