ATMS03-Surface Street Control (Market Package*)

Market Package Graphic       Transaction Set Diagram

Description

This market package provides the central control and monitoring equipment, communication links, and the signal control equipment that support local surface street control and/or arterial traffic management. A range of traffic signal control systems are represented by this market package ranging from fixed-schedule control systems to fully traffic responsive systems that dynamically adjust control plans and strategies based on current traffic conditions and priority requests. This market package is generally an intra-jurisdictional package that does not rely on real-time communications between separate control systems to achieve area-wide traffic signal coordination. Systems that achieve coordination across jurisdictions by using a common time base or other strategies that do not require real time coordination would be represented by this package. This market package is consistent with typical urban traffic signal control systems.

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. Benefits are well established for this Market Package and existing technologies and institutional arrangements support its deployment. Interjurisdictional issues which may be associated with broader implementations are also resolvable based on the success of existing wide area implementations. The arrival of the NTCIP standard further facilitates advanced implementations.
