TOS Ramp Metering Plugin Update for I-80 ICM, Contra Costa County, CA

Traffic Operation System (TOS) is the current ramp metering system deployed in Bay area, California. Under this project, CLR Analytics upgraded the TOS ramp metering plugin from Paramics version 4 to version 6.0. The metering control logic and queue override strategy were further checked for correctness. Some Paramics UI was also added to the plugin in order for users to see ramp metering locations through Paramics graphical interface.
