INFRASTRUCTURES * USA: Tired of waiting for a late bus? ... NOW NEW: Traffic signal optimization !
* D.C. - Buses will get priority with technology that holds lights at green
Washington,DC,USA -The Washington Business Journal, by Michael Neibauer -Nov 25, 2014: --The District is planning a major initiative to improve timeliness — one that could prove so effective, buses end up running early... The D.C. Department of Transportation is in search of a contractor to install transit signal priority (TSP) equipment at 103 signalized intersections... TSP systems, according to reams of federal research, can significantly improve bus travel times... As a bus approaches a TSP intersection, it sends a cellular signal to the traffic controller box, which automatically (without any human intervention) reviews the current traffic conditions and tweaks the signal timing. It can extend a green light by five to 10 seconds, said Wasim Raja, a DDOT traffic signal engineer, or sometimes bring the green up early... The Washington region was awarded a $58.8 million TIGER grant in 2010, from which the TSP system will be financed... That same grant is partly responsible for Alexandria's new dedicated Route 1 bus lane, D.C. traffic signal optimization, the Takoma-Langley Transit Center, replacement PRTC buses, and TSP systems on University Boulevard and Route 1 in Maryland, Van Dorn Street and Leesburg Pike...
