Equipment Package: Rail Operations Coordination

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: NJDOT TEOC
Processes: 1.1.3 - Generate Predictive Traffic Model
1.6.2.1 - Exchange Data with Rail Operations
1.6.2.3 - Manage Rail Traffic Control Data
User Service Requirements: 1.0 - TRAVEL AND TRAFFIC MANAGEMENT
1.2 - EN-ROUTE DRIVER INFORMATION
1.2.3 - DI shall provide an In-vehicle Signing capability.
1.2.3.2 - The DI In-vehicle Signing function shall include a long term capability to serve more of the traveler's needs.

1.6.2.5 - The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions.
1.6.2.5.2 - The data process function shall process traffic data to generate near term predictions of traffic conditions.
1.10 - HIGHWAY RAIL INTERSECTION
1.10.2 - HRI shall provide interfaces between highway and rail management functions.
1.10.2.1 - HRI shall provide information management interfaces between highway and rail to coordinate traffic, demand and schedules.
1.10.2.2 - HRI shall provide the capability for interactive real-time interfaces.
1.10.2.2.2 - HRI shall provide the capability to interface with traffic management functions for highway traffic coordination.
