Since it began in 2004, the Traffic Signal Optimization Program (TSOP) has completed 112 projects that involved over 1,100 signalized intersections in the region. Projects launched through this program provide technical assistance to member agencies. This helps to improve traffic signal coordination and enables optimization and review of operations through simulation modeling.
What is signal coordination and optimization? This involves implementing the best possible timing settings that govern the operation of a traffic signal. The goal is to respond to the demands of motor vehicles, bicycles, and pedestrians in a safe manner. Signal optimization leads to minimizing stops and delays, fuel consumption and air pollution emissions. It helps with maximizing the progression along an arterial.
Why is it necessary to optimize signals? Traffic signal optimization is one of the most cost-effective ways to improve traffic movement and make our streets safe and efficient. Signal optimization is performed for the following reasons:
Signal optimization projects produce benefit to cost ratios as high as 40 to 1.
The TSOP has been championed by the MAG Intelligent Transportation Systems Program to provide traffic engineering assistance for refining signal operations across the MAG region. Typical TSOP projects cost about $30,000, with projects involving multiple agencies or coordination with freeways costing as much as $50,000.
Get e-mail updates! /
In an effort to make information delivery faster, MAG has implemented an e-mail notification system that will make it easier to receive documents such as agendas, minutes and reports. Through a free subscription service called GovDelivery, MAG member agencies and the public will have better access to information that is posted on the MAG Web site.
The subscription service monitors specific Web pages for changes, and when a change is detected, the service sends an e-mail to subscribers notifying them of the change. Users can choose to subscribe to as many of the pages as they wish. There are about 130 monitored pages on the MAG Web site.
As a subscriber, you can choose not only what information you receive, you can also choose how often you receive it—immediately, daily, or weekly.
To subscribe, simply click on the link on the page that says “Sign up to receive email updates.” Users can also click on a Quick Subscribe link on various pages to see a full list and subscribe to any of the MAG pages. To subscribe, only a few pieces of information will be required, such as e-mail address, delivery preferences and organization.
Look for the red envelope icon on pages of interest.
