A simulation analysis of traffic flow elements for restricted truck lanes on interstate highways in Virginia / by Hoel, Lester A.(CARDINAL)323578; Peek, Jennifer L.; United States.Federal Highway Administration.(CARDINAL)139839; Virginia.Department of Transportation.(CARDINAL)291718; Virginia Transportation Research Council.(CARDINAL)195142;

Includes bibliographical references (pages 26-27).Final report.In recent years, increases in truck traffic on Virginia's highways have raised issues concerning safety and capacity on interstates such as I-81 and I-95. Lane restrictions represent a strategy that is intended to reduce conflicts between trucks and cars and facilitate traffic flow. Field experiments to determine the effects on existing traffic under lane restrictions for an interstate freeway segment are usually not feasible, and an alternative approach was selected. In this study, the simulation model FRESIM was used to estimate various traffic flow elements. The purpose of this study was to analyze changes in traffic flow elements (density, lane changes per vehicle, and speed differential) under conditions of restricted and unrestricted truck lane configurations. Prior to application of the simulation model to actual sites in Virginia, a scenario analysis was completed. The scenario analysis tested the variability of each traffic flow element considering the following variables: traffic volume, percentage of trucks, percentage of total volume by lane, presence or absence of lane restrictions, and grade. A statistical paired-sample t test was used to determine significant differences in the values of the three traffic flow elements when lane restrictions were applied. An analysis was also completed for three case studies in Virginia, located on I-81 near Buchanan, Christiansburg, and Wytheville. Two types of restrictions were tested: restricting trucks from the left lane and restricting trucks from the right lane. From the results obtained in this study several conclusions were drawn: (1) restricting trucks from the left lane with steep grades causes an increase in speed differential and may decrease density and the number of lane changes, (2) restricting trucks from the right lane causes an increase in the number of lane changes, and (3) site characteristics dictate the effects of truck lane restrictions. Based on the results of this study, it is recommended that (1) trucks be restricted from the left lane when grades are 4 percent or greater and (2) trucks not be restricted from the right lane. The study results did not support removal of truck lane restrictions in Virginia.Performed by the Virginia Transportation Research Council and sponsored by the Virginia Dept. of Transportation in cooperation with the Federal Highway Administration, under contract no.

Development of relationship between truck accidents and geometric design, phase I / by Miaou, Shaw-Pin,1955-(CARDINAL)311207; United States.Federal Highway Administration.Office of Research and Development.(CARDINAL)312001; Oak Ridge National Laboratory.(CARDINAL)157858;

Includes bibliographical references (pages 139-144).Introduction -- Literature review -- Data and summary statistics -- A Poisson regression model -- A negative binomial regression model -- Data needs -- Sample size requirements -- Appendix A -- References.Final report;The purpose of this study was to establish empirical relationships between truck accidents and highway geometric design. First, statistical frameworks based on Poisson and negative binomial regression models were proposed. Preliminary models were then developed using accidents and road inventory data from the Highway Safety Information System (HSIS). Three roadway classes were considered in the model development: rural Interstate, urban Interstate and freeway, and rural two-lane undivided arterial. The maximum likelihood method was used for estimation of model parameters. Information criterion, asymptotic t-statistic, and goodness-of-fit test statistics were employed to evaluate the estimated models. The model results based on data from one of the HSIS States--Utah, were used for analysis and for suggesting areas in which the quality and quantity of the existing HSIS data can be enhanced to improve the developed models. Despite the limitations in existing Utah data, some encouraging preliminary relationships were developed for horizontal curvature, length of curve, vertical grade, length of grade, shoulder width, number of lanes, and annual average daily traffic (AADT) per lane (a surrogate measure for vehicle flow density).Performed by Center for Transportation Analysis, Oak Ridge National Laboratory under contract no.

Streetfight : handbook for an urban revolution / by Sadik-Khan, Janette,author.(CARDINAL)625447; Solomonow, Seth,author.(CARDINAL)625449;

Includes bibliographical references (pages 299-335) and index.As New York City's transportation commissioner, Janette Sadik-Khan managed the seemingly impossible and transformed the streets of one of the world's greatest, toughest cities into dynamic spaces safe for pedestrians and bikers. Her approach was dramatic and effective: Simply painting a part of the street to make it into a plaza or bus lane not only made the street safer, but it also lessened congestion and increased foot traffic, which improved the bottom line of businesses. Real-life experience confirmed that if you know how to read the street, you can make it function better by not totally reconstructing it but by reallocating the space that's already there. Breaking the street into its component parts, Streetfight demonstrates, with step-by-step visuals, how to rewrite the underlying "source code" of a street, with pointers on how to add protected bike paths, improve crosswalk space, and provide visual cues to reduce speeding. Achieving such a radical overhaul wasn't easy, and Streetfight pulls back the curtain on the battles Sadik-Khan won to make her approach work. She includes examples of how this new way to read the streets has already made its way around the world, from pocket parks in Mexico City and Los Angeles to more pedestrian-friendly streets in Auckland and Buenos Aires, and innovative bike-lane designs and plazas in Austin, Indianapolis, and San Francisco. Many are inspired by the changes taking place in New York City and are based on the same techniques. Streetfight deconstructs, reassembles, and reinvents the street, inviting readers to see it in ways they never imagined.

Prediction of the expected safety performance of rural two-lane highways / by Harwood, Douglas W.(CARDINAL)312183; United States.Federal Highway Administration.Office of Safety Research and Development.; Midwest Research Institute (Kansas City, Mo.)(CARDINAL)143054;

Includes bibliographical references (pages 107-119).Introduction -- Overview of the accident prediction algorithm -- Base models -- Accident modification factors -- Sensitivity analysis results -- Implementation of the accident prediction algorithm within the IHSDM -- Conclusions, recommendations, and future enhancements -- References -- Bibliography -- Appendices.Technical report.This report presents an algorithm for predicting the safety performance of a rural two-lane highway. The accident prediction algorithm consists of base models and accident modification factors for both roadway segments and at-grade intersections on rural two-lane highways. The base models provide an estimate of the safety performance of a roadway or intersection for a set of assumed nominal or base conditions. The accident modification factors adjust the base model predictions to account for the effects on safety for roadway segments of lane width, shoulder width, shoulder type, horizontal curves, grades, driveway density, two-way left-turn lanes, passing lanes, roadside design and the effects on safety for at-grade intersections of skew angle, traffic control, exclusive left- and right-turn lanes, sight distance, and driveways. The accident prediction algorithm is intended for application by highway agencies to estimate the safety performance of an existing or proposed roadway. The algorithm can be used to compare the anticipated safety performance of two or more geometric alternatives for a proposed highway improvement. The accident prediction algorithm includes a calibration procedure that can be used to adapt the predicted results to the safety conditions encountered by any particular highway agency on rural two-lane highways. The algorithm also includes an Empirical Bayes procedure that can be applied to utilize the safety predictions provided by the algorithm together with actual site-specific accident history data.Performed by Midwest Research Institute and sponsored by the Office of Safety Research and Development, Federal Highway Administration.
