Real-Time Information Reduces Accidents and Congestion in Work ZonesAbstract:
This article discusses a way to reduce accidents and congestion in work zones by using a new device called the Adaptir (Automated Data Acquisition and Processing of Traffic Information in Real-Time), a technology developed by the Scientex Corp with support from the FHWA and the Maryland State Highway Administration (MSHA). This system measures traffic speeds using Doppler radar at several points within and upstream of a work zone. The data are then sent to a centralized control system, which analyzes the data to pinpoint patches of traffic congestion and delay and then selects the appropriate message to post on a variable message sign- or series of signs- just upstream of the site. This system is currently being tested in Kentucky and the article lists contact people for more information.
