| New solar-powered tag readers  To improve traffic management in New York state and across the country, a team of transportation researchers will be testing an array of wireless, solar-powered readers to monitor traffic flow. The units will be deployed to collect traffic data during the morning commute on busy Capital Region roads. The portable units, which are based on the same technology as E-ZPass tag readers, could be used to provide valuable data for a variety of applications, from decreasing congestion in work zones to assisting emergency evacuations. The reader is powered by solar panels, collects data on a laptop computer, and then sends the information wirelessly back to a server.The portable device sits on a trailer that can be transported by a vehicle with a normal-duty hitch. Planners could deploy a network of readers to monitor driving route choices, helping them decide where to place new roads or other construction projects, such as malls and housing developments. write your comments about the article :: © 2006 Construction News :: home page |
