Abstract:

This article discusses about the Virginia Smart Road that is frequently used by automobile researchers to test new ideas and concepts. The Virginia Smart Road is a unique, state-of-the-art, closed test-bed research facility managed by the Virginia Tech Transportation Institute and owned and maintained by the Virginia Department of Transportation. Over two-dozen major non-proprietary research projects use the Smart Road for testing in a given year. Participating organizations include heavy hitters such as car manufacturers, the Department of Transportation, the National Highway Traffic Safety A

Abstract:

This paper summarizes the work conducted by the Virginia Department of Transportation on self-consolidating concrete (SCC). Initially, a laboratory study with locally available materials was conducted to develop and evaluate the properties of SCC, including flow, segregation, strength, permeability, resistance to cycles of freezing and thawing, and drying shrinkage. Studies at two precast plants followed. Then, one of the precast plants furnished SCC for an arch bridge. The other plant fabricated two bulb T-beams with SCC. Studies also were conducted with cast-inplace SCC. A structures pad at

Abstract:

Bridges are a cultural resource that must be considered for historic significance under the Historic Preservation Act of 1966. The Virginia Transportation Research Council conducted pioneering studies of Virginia’s early metal truss bridges and concrete and masonry arch bridges during the 1970s and 1980s. However, no comprehensive evaluation of nonarched concrete bridges in Virginia had been undertaken, and it had become standard practice to evaluate these bridges on a case-by-case basis as projects arose that might affect them. Most of these studies were done by outside consultants, a time-co

Abstract:

The 1991 Americans with Disabilities Act Accessibility Guidelines required installation of a detectable warning surface (raised truncated domes) on sidewalk curb ramps to alert visually impaired persons to potential hazards at pedestrian crossings. In 1994 the requirement was temporarily suspended for 2 years. Whether visually impaired persons need (or want) detectable warnings on ramps and whether domes are the best option continue to be debated. The Virginia Department of Transportation's current standard requires an exposed aggregate (gravel mixed into concrete) surface on curb ramps. Seven

ABSTRACT Natural Bridge, in Rockbridge County, Virginia, is a geological arch carrying U.S. Route 11 over Cedar Creek. The area has significant historical and cultural importance; it is listed on the National Register of Historic Places and is a Virginia Historic Landmark. Until 2015, the arch and area below were privately owned and operated, with only the pavement structure of U.S. Route 11 held by the Virginia Department of Transportation. Since then, the arch and area below have been leased to the Virginia Department of Conservation and Recreation, potentially transferring liability to the

Abstract:

Although during the past several years significant progress has been made in improving safety on U.S. highways, the frequency and severity of crashes continue to be of concern. A better understanding of the factors associated with crashes will facilitate the identification of suitable countermeasures that could further reduce the occurrence of crashes. Results are presented from a study that determines how the characteristics of speed, flow, and geometry affect the crash rates for two-lane highways. Deterministic models that relate the crash rate with the mean speed, standard deviation of spee

Abstract:

This article explores some issues connected with how state departments of transportation develop research programs. The focus is on alternative processes for soliciting and prioritizing problem statements. Issues examined include how to increase the strategic direction of the solicitation and prioritization process and how to facilitate diverse participation in problem-statement development. Processes used in New York, New Jersey, and Virginia are explored.

Abstract:

The Virginia Department of Transportation (DOT) is responsible for maintaining more than 57,000 mi of roadway; a major part of that responsibility is implementation of Virginia DOT's anti-icing program. In FY 2003, the agency purchased more than 570,000 tons of sodium chloride; this salt is stored at nearly 300 locations statewide. This study's objectives were to assess the quantity and quality of salt-contaminated water generated from storm water runoff at Virginia DOT's road salt storage facilities and to evaluate management and treatment alternatives to reduce costs and better protect the e

Abstract:

In September 2015, the Virginia Department of Transportation instituted an active traffic management system on I-66 in Northern Virginia. I-66 is a major commuter route into Washington, D.C., that experiences significant recurring and nonrecurring congestion. The active traffic management system sought to manage existing capacity dynamically and more effectively with hard shoulder running, advisory variable speed limits, lane use control signs, and queue warning systems. An initial before-and-after analysis of the system’s operational effectiveness was performed with probe-based travel time da

Abstract:

All-way or multiway stop signs are perhaps the most controversial form of residential traffic control. Because stop signs are thought of as a panacea for many traffic problems, residents are likely to request all-way stop signs more frequently than any other form of control. The Virginia Department of Transportation receives requests to install all-way stop control (AWSC) on residential streets primarily to slow traffic and to reduce cut-through traffic volumes. The effectiveness of AWSC as a residential traffic management technique is evaluated. A comprehensive review of the literature and a

Abstract:

Cracking continues to be the number one concern about bridge deck construction. Rarely is a deck without cracks constructed. Transverse cracking mainly attributable to drying shrinkage is common in bridge decks and has been observed in many bridge decks newly constructed by the Virginia Department of Transportation (DOT). Shrinkage-reducing admixtures (SRAs) in concrete reduce shrinkage and are one of the most effective ways of reducing shrinkage cracking. A low modulus of elasticity and high creep also help minimize cracking. Lightweight concrete (LWC) has a lower modulus of elasticity, highe

abstract: Drawing on two contrasting images of the "highway to nowhere" in Baltimore and a stretch of the Blue Ridge Parkway in Virginia, this essay throws a spotlight on the politics of planning and designing roads in mid-twentieth century America. It examines the intertwined roles of race, class, and profession, focusing on the relationship between race and infrastructures as a systemic issue underlying individual decisions and policies. Race and infrastructures are prominent political topics now that the U.S. federal Department of Transportation is awarding grants to study tearing down inte
