摘要

Transit Signal Priority (TSP) systems have largely been deployed using localizedrncommunications between the vehicle and the intersection for which priority treatment isrndesired. This has been accomplished using a wide variety of short range, wirelessrncommunications technologies requiring an infrastructure at the intersection and equipment onrnthe vehicles. Such an infrastructure can be costly and in a City such as New York, with therndensity of intersections (there are over 12,400 intersections connected to the central system)rndeployment of TSP is cost prohibitive.rnDuring the past 3+ years, New York City has invested in the deployment of a city-wide,rnwireless network, dubbed NYCWiN, which provides ubiquitous wireless communications forrnboth vehicles and the traffic controllers. This paper describes a TSP system being deployedrnby New York City Department of Transportation (NYCDOT) that eliminates the need forrnlocalized TSP infrastructure by leveraging the existing in-vehicle systems to provide locationrnbased TSP request generation which originates within the vehicle and is transmittedrnwirelessly to the Traffic Management Center (TMC). The TMC can then validate the request,rnapply a set of business rules developed by NYCDOT, and transmit a specific TSP requestrnmessage to the Traffic Controllers using the same wireless network.rnSince the transit vehicles are now being purchased and equipped with on-board automaticrnvehicle location systems, automated fare systems, traveler information systems, and vehiclernmonitoring systems, adding another on-board “sub-system” to manage the TSP requestsrneliminates the need for the costly intersection based infrastructure.rnThis paper describes the design of the centrally managed TSP system and the adaptations tornthe National Transportation Communications for ITS Protocol (NTCIP) to support thisrnapproach.rnThis project started in July of 2010 and was in testing as of September, 2011, and is expectedrnto be completed by the end of the year - including operational tests on a route in lowerrnManhattan.
