ATMS07-Regional Traffic Management (Market Package*)

Market Package Graphic       Transaction Set Diagram

Description

This market package provides for the sharing of traffic information and control among traffic management centers to support regional traffic management strategies. Regional traffic management strategies that are supported include coordinated signal control in a metropolitan area and coordination between freeway operations and arterial signal control within a corridor. This market package advances the Surface Street Control and Freeway Control Market Packages by adding the communications links and integrated control strategies that enable integrated interjurisdictional traffic management. The nature of optimization and extent of information and control sharing is determined through working arrangements between jurisdictions. This package relies principally on roadside instrumentation supported by the Surface Street Control and Freeway Control Market Packages and adds hardware, software, and fixed-point to fixed-point communications capabilities to implement traffic management strategies that are coordinated between allied traffic management centers. Several levels of coordination are supported from sharing of information through sharing of control between traffic management centers.

Early Deployment

This market package has been identified as an early deployment due to a promising combination of low risk implementation characteristics, developing public or private markets for the package, and tangible system or user benefits. Traffic control strategies are increasingly regional in scope with emphasis on improving flow along major travel corridors. The potential benefits of integrated regional strategies have been clearly established through many trial implementations. Such implementations are also one of the focus areas within the Metropolitan ITS Infrastructure Initiative (see section 4.1). The peer-to-peer interjurisdictional arrangements and regional communications internetworking that enable regional control strategies facilitate implementation of many of the other traffic control and traveler information Market Packages.
