Traffic engineering principles are integral to the safe and efficient movement of people and products across the commonwealth.
Traffic engineering is the phase of Virginia Department of Transportation (VD)T) which deals with safe, economical, and efficient traffic movement on roads, streets, and highways, their networks, terminals, and abutting lands.
2011 Virginia Supplement to the Manual of Uniform Traffic Control Devices (Revision 1)
On July 30, 2013, the Federal Highway Administration (FHWA) found VDOT’s Revision 1 to be in substantial conformance with the 2009 Manual of Uniform Traffic Control Devices (MUTCD).
For more information regarding the 2011 Virginia Supplement to the MUTCD (Revision 1)
Revision 1 is effective Sept. 30, 2013, for daily operations. Revision 1 will be effective Jan. 1, 2014, for projects advertised for bid on, or after Jan. 1, 2014.
On the above noted date(s), all projects are to be constructed in accordance with the plans and the most current adopted editions of the Virginia Department of Transportation Road and Bridge Specifications, the Virginia Department of Transportation Road and Bridge Standards, the Virginia Supplement, the Virginia Work Area Protection Manual (WAPM) and the MUTCD.
In case of conflict between the MUTCD and the Virginia Supplement, or the Virginia Work Area Protection Manual, the adopted editions of the Virginia Supplement and the Virginia Work Area Protection Manual and subsequent revisions shall govern.
A list of editorial revisions and clarifications that constitute Revision 1 of the Virginia Supplement to the 2009 MUTCD is at:
The WAPM, which replaces Part 6 of the 2009 MUTCD in its entirety, is the current version.
This version became effective on Jan. 1, 2012. For more information:
2009 Manual on Uniform Traffic Control Devices, with Revisions 1 and 2, May 2012
The most current version of the MUTCD is the 2009 edition with Revisions 1 and 2 incorporated, dated May 2012, can be found at:
A document describing how the 2009 edition with Revisions 1 and 2 incorporated (May 2012) differs from the 2009 Edition (December 2009) is available at:
Highway Safety Improvement Program
The 2005 Safe, Accountable, Flexible, and Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU; Public Law 109-59) establishes a new core Highway Safety Improvement Program (HSIP) that is structured to make significant progress in reducing highway fatalities and serious injuries.
The HSIP incorporates the previous Hazard Elimination Safety Program (named HES under TEA-21st) with the Bicycle and Pedestrian Safety Program under § 23 USC Section 148, and defines set-aside funds for Highway-Rail Grade Crossing Safety Program under § 23 USC Section 130.
VDOT has developed a Highway Safety Improvement Program (HSIP) for Virginia that involves the identification of high crash locations, an analysis of hazards, problems and countermeasures, and the prioritization and scheduling of improvement projects.
This program includes:
- Highway Safety Program (HSP), previously called HES
- Bicycle and Pedestrian Safety Program (BPSP)
- Highway-Rail Grade Crossing Safety Program (H-RGCP)

Road Safety Assessments
A Road Safety Assessments (RSA), also known as Road Safety Audits, are defined as a more formal examination of existing highways or design projects in which a team of independent and multidisciplinary examiners analyzes the site crash history and develops potential safety countermeasures.
The overall objective is to identify crash trends for roadway users and recommend measures to mitigate them.
VDOT has identified the RSA as a critical strategy to design and construct engineering improvements for several of the emphasis areas in Virginia’s Strategic Highway Safety Plan.
These include intersection and roadway departure crashes.
VDOT’s Traffic Engineering Division promotes RSA as the foundation of providing excellent transportation safety planning and recommends its inclusion throughout the project development / delivery process.
In cooperation with VDOT’s Transportation Mobility Planning Division, and as a first step, RSA procedures have been integrated into the Strategically Targeted Affordable Roadway Solutions (START) program.
To systematically implement Rasps in Virginia, the Traffic Engineering Division has developed RSA guidelines and tools to bring together relevant RSA resources for all stakeholders.

Traffic Monitoring Program
VDOT conducts a traffic monitoring program where traffic count data are gathered from sensors in or along streets and highways and other sources.
From this data, estimates of the average number of vehicles that traveled each segment of road are calculated.
Traffic volume estimates - County by county statistics that include more than 100,000 segments of roads and highways, ranging from several mile sections of interstate highways to very short sections of city streets.
