AHB25: The Traffic Signal Systems Committee

Welcome

Welcome to the web site of the Traffic Signal Systems Committee (TSSC), a technical standing committee AHB25 (previously A3A18) of the Transportation Research Board (TRB) of the National Academies. TSSC is concerned with provision of the safe and efficient movement of people and goods on surface streets through the use of traffic management systems.

The Traffic Signal Systems Committee membership is listed on the Membership page. Anyone interested in Traffic Signal Systems is welcome to become a Friend of the Committee. You can sign up on the Membership page under Contact Information/ Join Committee Friends.

Committee communication takes place primarily through our E-mail list (Listserv). Please sign up to join the list if you haven't yet done so. Members and Friends who have already signed up and do not receive e-mail from the list, please notify the Webmaster.

The scope of the Committee's activities include:

• system design, implementation, operations, and maintenance;
• development of traffic operations centers;
• development of traffic management strategies;
• integration and operational evaluation of surface street systems with freeway, traveler information, and transit systems; and
• incorporation of surface street systems into Intelligent Transportation Systems (ITS).

Announcements --Summer Meeting

The summer meeting of the TRB Traffic Signal Systems (TSS) Committee will include a Workshop on Traffic Signal Logic Using Advanced Sensor Information (NCHRP Project 3-66). The workshop will focus on the operation of coordinated traffic signals and how advanced sensor data can be used to address issues related to controller logic and quality of service. The summer meeting will also include a Tutorial Workshop on using UML to model traffic signal control logic, a technical field tour of the Michigan Field Operational Test (FOT) of Vehicle Infrastructure Integration (VII), and TSS Committee and Sub-Committee Meetings.
