ATMS15-Railroad Operations Coordination (Service Package*)

Description

This service package provides an additional level of strategic coordination between freight rail operations and traffic management centers. Rail operations provides train schedules, maintenance schedules, and any other forecast events that will result in highway-rail intersection (HRI) closures. This information is used to develop forecast HRI closure times and durations that may be used in advanced traffic control strategies or to enhance the quality of traveler information.

Associated Objectives and Performance Measures

Objective Performance Measure
Annual rate of change in regional average commute travel time will not exceed regional rate of population growth through the year Y. Average commute trip travel time (minutes).
Improve average travel time during peak periods by X percent by year Y. Average travel time during peak periods (minutes).
Maintain the rate of growth in facility miles experiencing recurring congestion as less than the population growth rate (or employment growth rate). Percent of lane-miles (or rail) operating at LOS F or V/C > 1.0
Reduce excess fuel consumed due to congestion by X percent by year Y. Excess fuel consumed (total or per capita).
Reduce hours of delay per capita by X percent by year Y. Hours of delay (person-hours).
Reduce hours of delay per capita by X percent by year Y. Hours of delay per capita.
Reduce hours of delay per driver by X percent by year Y. Hours of delay (person-hours).
Reduce hours of delay per driver by X percent by year Y. Hours of delay per driver.
Reduce the annual monetary cost of congestion per capita for the next X years. Cost (in dollars) of congestion or delay per capita.
Reduce the number of hours per day that the top 20 most congested roadways experience recurring congestion by X percent by year Y. Hours per day at LOS F or V/C > 1.0 (or other threshold).
Reduce the percentage of facility miles (highway, arterial, rail, etc.) experiencing recurring congestion during the peak period by X percent by year Y. Percent of lane-miles (or rail) operating at LOS F or V/C > 1.0
Reduce the regional average travel time index by X percent per year. Travel time index (the average travel time during the peak period, using congested speeds, divided by the off-peak period travel time, using posted or free-flow speeds).
Reduce the share of major intersections operating at LOS Z by X percent by year Y. Percent of intersections operating at LOS F or V/C > 1.0
Reduce total energy consumption per capita for transportation by X percent by year Y. Total energy consumed per capita for transportation.
Reduce total fuel consumption per capita for transportation by X percent by year Y. Total fuel consumed per capita for transportation.

 
Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The Rail Operations system sends train schedules, maintenance schedules, and other information that supports forecast of highway-rail intersection closures (railroad schedules) to the Traffic Management Subsystem. The Rail Operations also notifies the Traffic Management Subsystem of railway-related incidents or other advisories (railroad advisories).

  2. When an equipment problem is identified or anytime conditions require attention, the Traffic Management Subsystem will notify (hri advisories) the Rail Operations. The Traffic Management Subsystem will control equipment (hri control data) at highway-rail intersections. The Traffic Management Subsystem may use surveillance cameras to monitor the intersections, gates or signals to control traffic through the intersections or signs or signals to display information on train crossings to travelers. Further functions are provided by ATMS13, Standard Railroad Grade Crossing, and ATMS14, Advanced Railroad Grade Crossing.

  3. The status of highway-rail intersection equipment (hri status) including both the current state and mode of operation and the current equipment condition is monitored by the Traffic Management Subsystem. The status can be requested (hri request) by the Traffic Management Subsystem or the Roadway Subsystem can send it when warranted, either when a problem is detected or on a set interval.

  4. The Traffic Management Subsystem can share the current and/or expected status of highway-rail intersections (road network conditions) with an Information Service Provider.
