Available in PDF, EPUB and Kindle. Book excerpt: Congestion on our nation's highways, especially in urban areas, is a serious problem that is growing steadily worse. In Virginia, it is estimated that 28 percent of the daily vehicle miles of travel (VMT) occurring during peak hour traffic is congested (volume/service flow ratio> 0.75). Further, it is estimated that the cost of urban area congestion in Virginia will amount to more than $4 billion in the year 2000. Transportation professionals in Virginia need to be cognizant of and familiar with congestion-reducing measures so as to implement them at every opportunity. Accordingly, this research was conducted to (1) develop a categorical list of congestion- reducing measures, and (2) document the implementation of and experiences with these measures in Virginia. The latter included a subjective evaluation of each measure's effectiveness, cost, and barriers to implementation. The scope was limited to a literature review and a survey of transportation officials in Virginia. Based on the literature, 53 congestion-reducing measures were categorized by whether they manage the existing supply of transportation facilities, add to that supply, manage the existing transportation demand, or control demand growth. Experiences with these measures were documented from the survey of transportation professionals in Virginia. Conclusions were reached regarding the effectiveness, cost, and ease of implementation of individual measures as well as categories of measures.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to define a performance measure(s) that could be used to show congestion levels on critical corridors throughout Virginia and to develop a method to select and calculate performance measures to quantify congestion in a transportation system. Such measures could provide benchmarks or base values of congestion to aid in measuring changes in the performance of the highway system. A general method was developed to monitor congestion using performance measures and the intelligent transportation system information from the Virginia Smart Travel Lab. Two performance measures were selected for investigation: total delay and the buffer index. These performance measures were applied to evaluate congestion levels on the roadways in the Hampton Roads region of Virginia. Each measure shows a different dimension of congestion. In general, total delay is better suited for use by transportation professionals because it is given in units of vehicle-minutes and applies to all vehicles on a segment of roadway. The buffer index is suitable for use by the public because it addresses individual vehicle trip travel time and can be used for trip planning. The buffer index is also important to transportation professionals as a measure of variability. This research provides information on the changing state of congestion on selected corridors throughout Virginia. It will help the Virginia Department of Transportation determine the best ways to measure congestion and provide a way to compare congestion over periods of time to ascertain if the delay has grown worse or improved. This research can also help establish a benchmark for traveler delay on Virginia's roadways.

Available in PDF, EPUB and Kindle. Book excerpt: Persistent daily congestion, which has been increasing in recent years, is commonly experienced for several hours or more during the morning and evening on Virginia's urban freeways. Many of these roadways are at or near capacity, which causes severe delays and backups. One solution to reducing recurring congestion is to add capacity by building more lanes; however, this is usually the last resort as it is an expensive and time-consuming approach. Another strategy proposed to combat recurring congestion is to manage the current freeways so that they operate more efficiently. Reducing congestion through better managed freeways has numerous documented benefits, including reducing travel times, smoothing the traffic flow, increasing average fuel economy, shortening the rush hour period and reducing vehicle queuing. The highway operational strategies implemented to reduce recurring congestion have shown promising results abroad where there is an extensive use of active traffic management systems. To prove the effectiveness of a better managed freeway in mitigating recurring congestion, this study tested the effectiveness of an active traffic management system on a simulated model of I-66 and I-95 in Northern Virginia. Hard shoulders, variable speed limits, and ramp metering are several active traffic management systems simulated in this study. The simulation model was based on the geometric characteristics, ramp volumes, vehicle flows, and speeds of actual recorded conditions. Compared with the simulated control conditions, the results of the study indicated improvements in average fuel economy, travel delay, delay of the onset of congestion, and reduction of queues. The two active traffic management systems, i.e., variable speed limits and hard shoulders, showed the highest potential for reducing recurring congestion and should be considered as potential countermeasures in congested corridors. Although the capital costs of implementing these strategies would be high, the return on investment in the first year of operations is estimated at $500,000, with the potential to grow to as much as $8 million annually in subsequent years.

This book was released on 2002 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to evaluate the Virginia Department of Transportation's (VDOT's) Residential Traffic Calming Guide. A 2-year pilot program served as a means to evaluate the Guide. The results of the evaluation enabled VDOT to strengthen its Guide based, to a large extent, on the lessons learned in the pilot program and to prepare for effective statewide implementation of this customer service-oriented program. This report documents the activities of the pilot program and VDOT's Residential Traffic Calming Committee, which administered the program. Numerous conclusions were drawn by the researchers based on specific experiences during the pilot program. The conclusions ranged from the usefulness of specific elements of the Guide, actions that worked well for a particular county, the description of side effects from having the pilot program in place, lessons learned from specific traffic calming projects, and a list of other activities that have occurred under the moniker of traffic calming. The recommended changes to the Guide that were identified during this effort and incorporated in the latest version of the Guide are described. An implementation plan outlines a suggested approach to transition from a pilot to a statewide program. The plan emphasizes the Guide as a component of a residential traffic management program.
