Traffic Signal Programs

Through traffic signal programs based on objectives and performance measures, program stakeholders can adeptly identify management and operations (M&O) strategies that may be considered during planning for operations. M&O strategies like centralized traffic signal systems and adaptive signal control technology applied at the local, regional, or State level may contribute to the accomplishment of operations objectives outlined in a transportation plan. For example, a traffic signal coordination program may be one project a region implements to reduce delay on a network in combination with other strategies. When seeking to implement a traffic signal program, signal engineers need to be able to articulate the objectives of their specific project within the context of the broader operations objectives for their region; this will increase the likelihood of the project being programmed in the transportation improvement program.

Regional cooperation in traffic signal operations offers significant potential benefits. Regional traffic signal operations programs (RTSOP) are one of several concepts for transportation operations that agencies can use to address operational issues at the regional level. RTSOPs represent the collaborative efforts of what may be a combination of State, county, and city departments of transportation; transit agencies; metropolitan planning organizations; and other stakeholders to address regional mobility issues, particularly on arterial networks that span multiple jurisdictions. By working collaboratively, participating stakeholders can achieve significant benefits by addressing traffic signal operational issues from a regional perspective.
