User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.10Highway-Rail Intersection
1.10.3At all HRIs with active railroad warning systems, HRI shall manage the traffic in the intersection.
1.10.3.1HRI shall be capable of augmenting the intersection with standard highway traffic signal devices.
1.10.3.3HRI shall provide an Intelligent Intersection Controller (IIC) function to manage highway and rail traffic in the intersection.
1.10.3.3.2IIC function shall control active railway warning devices, including flashing lights and physical barriers for highway and walkway lanes at HRIs.
1.10.3.3.3IIC function shall provide an intersection surveillance system to derive the real-time status of traffic in the intersection.
1.10.4HRI shall include a Standard Speed Rail (SSR) Subservice to manage highway and rail traffic at HRIs for rail lines with operational speeds less than 80 MPH.
1.10.4.1SSR shall include active railroad warning systems at designated HRIs.
1.10.5HRI shall provide a High Speed Rail (HSR) Subservice for HRIs on rail lines with operational speeds between 80 and 125 MPH.
1.10.5.1HSR shall include active roadside message devices to provide highway closure information at HSR HRIs.
1.10.5.2HSR shall provide special safety features to enhance safety.
1.10.5.2.2HSR shall include a positive barrier function( e.g. four quadrant gates) to close the intersection to highway traffic for rail lines operating at speeds over 110 MPH.
1.5.2TSI shall include an Information Access function that allows travelers to access the available information.
1.5.2.5Information Access shall provide the capability for travelers to access the TSI information via any of, but not limited to, the following methods:
1.5.2.5(a)Highway advisory radio.
1.6TRAFFIC CONTROL
1.6.0ITS shall provide a Traffic Control capability. Traffic Control provides the capability to efficiently manage the movement of traffic on streets and highways. Four functions are provided which are (1) Traffic Flow Optimization, (2) Traffic Surveillance, (3) Control Function, and (4) Provide Information. This will also include control of network signal systems with eventual integration of freeway control.
1.6.3Traffic Control shall include a Control Function.
1.6.3.3The Device Control Function shall provide the capability to exercise control over those devices utilized for traffic control.
1.6.3.3.1Device Control shall include the capability to control traffic signalization, including rapid modification of signalization parameters to respond to traffic requirements.
1.6.3.3.2Device Control shall include the capability to control dynamically traffic signing.
1.6.3.3.4Device Control shall include the capability to exercise dynamic control over the infrastructure (such as reversible-lanes, turning restrictions, etc.).
1.6.3.4Device Control shall communicate control data to the following devices.
1.6.3.4(a)Traffic signals.
1.8TRAVEL DEMAND MANAGEMENT
1.8.0Travel Demand Management will generate and communicate management and control strategies that will support and facilitate the implementation of TDM programs, policies and regulations. It consists of two major functions which are (1) Increase Efficiency of Transportation System and (2) Provide Wide Variety of Mobility Options.
1.8.2TDM shall include a processing function.
1.8.2.8The processing function's generation of management and control strategies for HOV facilities shall include as factors, but not be limited to, the following:
1.8.2.8(a)Auto occupancy requirements.
1.8.2.8(b)Priority for selected vehicle types at ramps.
1.8.2.8(c)Priority for selected vehicle types at signalized intersections.
1.8.3TDM shall include a sensors/control function.
1.8.3.1The sensors/control function shall provide the capability to gather information needed for the generation of management and control strategies to include, but not be limited to the, following:
1.8.3.1(c)Vehicle occupancy.
5.0EMERGENCY MANAGEMENT
5.2EMERGENCY VEHICLE MANAGEMENT
5.2.3Emergency Vehicle Management Service shall be provided by a Signal Priority System.
