Across the rural sections of Colorado, CDOT broadcasts information about weather and traffic conditions on AM 530, using a series of transmitter towers and repeater sites. The system effectively provides immediate site specific weather information. In addition, announcements can be programmed for road closures, traveler forecasts, and changing traffic conditions. Spring and summer rain storms in rural sections of Colorado often create flash flood conditions. This proactive high-water warning system has greatly reduced vehicular accidents at several critical channel crossings across Colorado.
Steep mountain grades present problems for commercial vehicle operators.
Several attempts to communicate these dangers to commercial vehicle drivers have been made. Applications such as static warning signs, truck speed limits, and educational videos at state weigh stations have all been used to minimize this condition. First, the trafAc loop detectors trigger the system. Then, WIM determines the truck weight, speed, and axle configuration. Currently, British Columbia, Oregon, and West Virginia are designing and constructing similar systems.
