Rail Operations Coordination Equipment Package

 Architecture Geographic Scope

Description:

 This equipment package provides strategic coordination between rail operations and traffic management centers. It receives train schedules, maintenance schedules, and any other forecast events which will result in highway-rail intersection (HRI) closures from Rail Operations. The provided information is used to develop forecast HRI closure times and durations which may be applied in advanced traffic control strategies or delivered as enhanced traveler information. This equipment package includes the processing and algorithms necessary to derive HRI closure times and the communications capabilities necessary to communicate with rail operations and interface to the traffic control and information distribution capabilities included in other Traffic Management Subsystem equipment packages.

 

Included in:

 City of Brownsville TMC
City of Harlingen TMC
City of McAllen TMC
TxDOT Pharr District TMC

Processes:
1.1.3Generate Predictive Traffic Model
1.6.2.1Exchange Data with Rail Operations
1.6.2.3Manage Rail Traffic Control Data
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.2EN-ROUTE DRIVER INFORMATION
1.2.3DI shall provide an In-vehicle Signing capability.
1.2.3.2The DI In-vehicle Signing function shall include a long term capability to serve more of the traveler's needs.
1.2.3.2.3The In-vehicle Signing function shall provide the capability to utilize data from roadside environmental sensors as inputs to warning messages.
1.6TRAFFIC CONTROL
1.6.0ITS shall include a Traffic Control (TC) function. 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, and (4) Provide Information. This will also include control of network signal systems with eventual integration of freeway control.
1.6.2TC shall include a Traffic Surveillance function.
1.6.2.5The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions.
1.6.2.5.2The data process function shall process traffic data to generate near term predictions of traffic conditions.
1.10HIGHWAY RAIL INTERSECTION
1.10.2HRI shall provide interfaces between highway and rail management functions.
1.10.2.1HRI shall provide information management interfaces between highway and rail to coordinate traffic, demand and schedules.
1.10.2.2HRI shall provide the capability for interactive real-time interfaces.
1.10.2.2.2HRI shall provide the capability to interface with traffic management functions for highway traffic coordination.
