Different types of existing roadside systems are<br/>identified:<br/><br/>a. Roadside Substation (RSS): a system deployed along high-ways<br/>and includes sensors (loops), control logic and actuators. The<br/>system can run as a stand-alone closed loop system i.e. run standalone<br/>local traffic control functions (e.g. traffic jam tail detection and<br/>warning via Variable Message Signs) or can be controlled by the<br/>TMS;<br/><br/>b. Traffic Light Controller (TLC): a TLC is a specific type of roadside<br/>system. It includes the input from loop detectors or other sensors, a<br/>control logic, and the actuation of the traffic lights. A TLC can be<br/>run as a stand-alone closed-loop traffic control system. A TLC can<br/>also be controlled by a central TMs, e.g. in green wave applications<br/>between different TLC’s. A TLC is deployed on urban road or can<br/>be deployed at highway access roads for access control;<br/>
