Physical Object: Traffic Management Center

TMC Multimodal Crossing Management


'TMC Multimodal Crossing Management' remotely monitors and manages multimodal crossings, including draw bridges and other crossings between highway traffic and other modes. Equipment controlled includes warning lights, gates, dynamic message signs, and other systems that provide driver information and control traffic at multimodal crossings. Railroad grade crossings are covered by other functional objects.

This functional object is included in the "Traffic Management Center" physical object.

This functional object is included in the following service packages:

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


# Requirement
01 The center shall remotely control traffic signal controllers for use at major multimodal crossings.
02 The center shall remotely control driver information systems (such as dynamic messages signs, highway advisory radios (HAR), and equipment that controls warning lights and gates) to notify drivers of closure durations and times at multimodal crossings.
03 The center shall collect operational status for the equipment at multimodal crossings.
04 The center shall collect fault data for the equipment at multimodal crossings for repair.
05 The center shall distribute multimodal crossing information to other centers for dissemination to travelers.


The following table lists the standards associated with the functional object itself (as opposed to standards associated with an interface).
