Experts say costs are dropping to install smart work-zone systems, thanks to lower prices for gear and greater availability of portable systems.
One of the applications of intelligent traffic systems (ITS), smart work zones are currently best suited for freeways and expressways with higher speeds, multiple lanes and sometimes chaotic traffic.
Prices are dropping for the electronics, computers, and communications equipment used to collect traffic information, process it and then act on it, says Ken E. Johnson, a Minnesota Department of Transportation engineer who specializes in work-zone traffic control.
“The technologies are getting such that it will be less costly to install intelligent work-zone systems,” Johnson says, adding that there are now different and less expensive ways to detect what traffic is doing, from LIDAR (light detection and ranging) to Bluetooth sensors to Doppler systems. “For project managers who are considering using them, the price has dropped quite a bit.” Click here to continue reading…
