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.
