Intelligent Transportation Systems (ITS) is
defined by USDOT federal regulations as“…electronics, communications, or information processing
used singly or in combination to improve the efficiency or safety of a
surface transportation system ”(see 23CFR Part 940 – ITS Architecture and Standards).
The basic goal of ITS programs is to use modern computer and communications
technologies to provide for more efficient and effective management of existing
transportation systems. When integrated into the transportation system
infrastructure, and in vehicles themselves, these technologies help monitor and manage traffic flow,
reduce congestion, provide alternate routes to travelers, enhance productivity, and
save lives, time and money.
Examples of ITS include the following:
systems - Provides information on traffic conditions, accidents and
other incidents, weather information, etc. directly to travelers,
enabling them to make more informed decisions on routes.
Traffic management systems
- Employs a variety of detectors, cameras, and other systems to
monitor traffic, optimize traffic signal timings on major arterials,
and other means to control traffic flow.
Incident Management Systems – Provides traffic operators with tools to allow
quick and efficient response to accidents, hazardous spills, and other
Emergency Vehicle Pre-Emption Devices – Carried on ambulances, fire trucks
and other emergency vehicles, it enables such vehicles to remotely change
traffic signals for safe and speedy passage through intersections (usually by
advancing or extending “green” time so traffic can move through ahead of
Automatic Vehicle Location – GPS-based vehicle tracking system, used on
buses, paratransit vehicles, long-haul freight trucks to monitor vehicle location
and provide location information to dispatchers and transit patrons.
The underlying principle for ITS deployment is adherence to established standards
and an overall framework that can allow all elements of the transportation network to
function and interact as one system. This is achieved through the National ITS
Architecture, which provides a common framework for planning, defining, and
integrating ITS; and through
Regional ITS Architecture, which is the regional
framework for ensuring institutional agreement and technical integration for
implementation of ITS projects. Federal policy provides that regional ITS
architecture should be consistent with the transportation planning process for
Statewide and Metropolitan Transportation Planning.
The Commonwealth of Virginia is divided into five regions for ITS planning and
project development. The Richmond Regional TPO along with Tri-Cities Area MPO,
portions of the Fredericksburg Area MPO, and rural area jurisdictions are covered by VDOT’s Central Region. ITS program development and project deployment for
jurisdictions in the Central Region is provided through VDOT’s
Region ITS Architecture Implementation Plan and
Virginia Central Region ITS
Architecture Maintenance Plan. The Implementation Plan covers the process for
ITS deployment, project sequencing, developing various levels of agency/jurisdiction
cooperative agreements, and establishing standards for exchange of information
among ITS systems. The Maintenance Plan establishes the agency responsible for
ITS architecture maintenance, defines the ITS Architecture
maintenance process, the architecture update process, and defines the ITS
Architecture Maintenance Committee.
ITS Work Group
The Richmond Region
ITS Work Group was established under the MPO’s Technical Advisory Committee (TAC) to provide
planning and programming support and assistance for TAC on ITS related matters.
Members are appointed by TAC members for their respective
jurisdictions/agencies. Representatives from the Crater Planning District
Commission and the FHWA Virginia Division office are included in the work group. The
work group’s duties and responsibilities are subject to TAC review, consideration and
The primary responsibilities for the ITS/TAC
Work Wroup are as follows:
Provide a regional forum for discussion of ITS related issues, projects, plans
Facilitate and promote use and maintenance of the VDOT Central Region ITS
Promote and assist in integrating the ITS architecture into the regional planning
Provide recommendations to TAC on ITS projects, programs and services for
development and/or funding consideration.
