NCDOT to install advance traffic warning system on I-277

The North Carolina Department of Transportation (NCDOT) is to install an advance warning system on the Interstate 277 (I-277) outer loop between Tryon Street and Interstate 77 in Charlotte, North Carolina. This system will detect traffic data such as volume and speed, alerting motorists to backups that frequently occur on the ramp from I-277 outer to I-77 north.

The 4775 North Carolina Department of Transportation (NCDOT) is to install an advance warning system on the Interstate 277 (I-277) outer loop between Tryon Street and Interstate 77 in Charlotte, North Carolina.

This system will detect traffic data such as volume and speed, alerting motorists to backups that frequently occur on the ramp from I-277 outer to I-77 north.

The $188,000 project was awarded to Consolidated Power of Mooresville, who will install the detection warning system, consisting of two microwave vehicle detection (MVD) units and two flashing LED beacons.  The MVD units will collect traffic data and send it to a processor on site for analysis; the system will then send a message to activate one or both of the flashing beacons.

Once traffic reaches speeds below 20 mph, the first beacon near the I-77 North exit ramp will activate. If traffic continues to back up toward Tryon Street, the second beacon will be activated. The contract also requires additional signage warning motorists of slow or stopped traffic.

NCDOT operates other similar detection systems on NC 58 in Carteret County, on I-26 in Polk and Henderson Counties, and on I-40 in Iredell County.

    A fledgling advanced lane management assist system can take the guesswork out of selecting the right lane on a congested freeway, as its inventor Robert Gordon explains. As drivers we’ve all done it and control room staff see it all the time – motorists on congested freeways switching into what they perceive is a faster lane, only to come to a halt a few moments later and watch vehicles in the other lanes continue to move past. Now, by re-analysing readily available data in an advanced lane management as

    The Port Mann Bridge in Vancouver is a prime example of how the latest ITS systems enable new infrastructures to be built and paid for while still providing additional user benefits. Vancouver has 2.2 million inhabitants and, like so many major cities, is divided into two by a river, the Frazer river. This combination makes Vancouver the second most congested city in North America and the most congested in Canada. Through the middle of the city runs the Trans-Canadian Highway 1 which crosses the Frazer Riv

    Are co-operative systems and personal privacy mutually exclusive? Not necessarily, says Neil Hoose. But the more advanced the application, the greater the concession of privacy may have to become. ITS Stockholm in 2009 and the Cooperative Mobility Showcase event which took place alongside Intertraffic in Amsterdam in March this year both featured live, on-street demonstrations of safety and driver information applications that used Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communications,
