Physical Object: ITS Roadway Equipment

Roadway Multimodal Crossing Control

Overview

'Roadway Multimodal Crossing Control' monitors multimodal crossings and monitors and controls traffic control equipment in the vicinity of the crossing. Equipment controlled includes warning lights, gates, dynamic message signs, and other systems associated with multimodal crossings. It manages draw bridges and miscellaneous other crossings between highway traffic and other modes. Railroad grade crossings are covered by other functional objects.

This functional object is included in the "ITS Roadway Equipment" physical object.

This functional object is included in the following service packages:

This functional object is mapped to the following Functional View PSpecs:

Requirements

# Requirement
01 The field element shall include sensors to monitor requests from non-highway traffic to cross at multimodal crossings for specified durations (such as draw bridges and miscellaneous other interference crossings between highway traffic and other modes such as river traffic, aircraft, etc.); the sensors are under center control.
02 The field element shall include signals to control traffic at multimodal crossings on surface streets, under center control.
03 The field element shall include driver information systems (such as dynamic messages signs, highway advisory radios (HAR), and equipment that controls warning lights and gates) that advise drivers at multimodal crossings, under center control.
04 The field element shall provide operational status for the sensors, signals, and driver information systems equipment at multimodal crossings to the center.
05 The field element shall provide fault data for the sensors, signals, and driver information systems equipment at multimodal crossings to the center for repair.
06 The field element shall forward all requests for right-of-way at multimodal crossings to the controlling center.
