This report presents results from the 2010 National Occupant Protections use Survey (NOPUS) Controlled Intersection Study,

Located in the center of downtown Rome, New York, Fort Stanwix currently experiences several transportation-related issues affecting visitor access to the park and overall visitor experience. As a follow-up to a 2006 Alternative Transportation Study, the goals of this report are threefold: 1) to update the 2006 study's existing conditions report to reflect recent changes that have occurred in and around the park, 2) to evaluate five specific areas of concern to the park, which were identified in the 2006 study, and 3) to identify opportunities to a) address these areas of concern; b) improve visitor experience at the park; and c) strengthen the park's relationship with the city by furthering city and county goals. The five areas of concern to the park are nonmotorized trail connections, vehicular signage and wayfinding, parking, pedestrian access, and shuttle feasibility. Findings for each of these focus areas are summarized.

This work describes the statistical analyses based on data for calendar years 1995 to 2007 from the Fatality Analysis Reporting System (FARS) and the General Estimates System (GES) of the National Automotive Sampling System (NASS) estimate the long-term effectiveness of antilock brake systems (ABS) for passenger cars and LTVs (light trucks and vans) subsequent to the 1995 launch of public information programs on how to use ABS correctly.

The Crash Outcome Data Evaluation System (CODES) is a program facilitated by the National Highway Traffic Safety Administration as a component of its State Data Program. CODES uniquely uses probabilistic methodology to link crash records to injury outcome records collected at the scene and en route by emergency medical services, by hospital personnel after arrival at the emergency department or admission as an inpatient and/or, at the time of death, on the death certificate. CODES is designed to foster and cultivate crash-outcome data linkage for highway safety applications at the State level, supporting State Highway Safety Offices, State Public Health and Injury Prevention Departments, State Emergency Medical Services Agencies, State transportation departments, and other such agencies; and to facilitate participation in NHTSA coordinated multistate studies using linked data at the Federal level. This document is intended to inform traffic safety professionals, from those in CODES programs to those in the agencies they support, as well as all others interested in traffic safety, on best-practice applications available through linked CODES data.

This purpose of this report is to determine the effect of rear turn signal color on the likelihood of being involved in a rear-end crash. Federal Motor Vehicle Safety Standard No. 108 allows rear turn signals to be either red or amber in color. Previous work on this subject includes laboratory experiments and analyses of crash data that suggest amber rear turn signals are beneficial. The present study was designed around the concept of "switch pairs" - make-models of passenger vehicles were identified that had switched rear turn signal color, and crash involvement rates were computed before and after the switch.

The objective of this study is to analyze passenger vehicle crashes involving children up to 15 years old. The Fatality Analysis Reporting System (FARS), and National Automotive Sampling System (NASS) General estimates System (GES) were consulted to establish restraint usage trends over a 5-year period from 1998 through 2002. The study is intended to provide a better understanding of where to focus future safety efforts designed to improve highway transportation for children.

This report was one in a series of pedestrian safety synthesis reports prepared for the Federal Highway Administration (FHWA) to document pedestrian safety in other countries. Australia is a federation of States and Territories, and government responsibilities broadly mirror that in the USA. Local government is responsible for 80 percent of the road network, though the less heavily traveled parts. Australia is highly urbanized (notwithstanding large tracts of sparsely populated land). Almost 40% of the population lives in Melbourne or Sydney, and another 20% in Brisbane, Perth, and Adelaide. Australia has been a pioneer of traffic calming in the form of Local Area Traffic Management, particularly in residential neighborhoods. Innovations are evident in the traffic signal area. Puffin crossings with infrared detectors seem promising. Pelican crossings are likely to find ready application, and having them set up for double cycle operations appears to offer benefits. Australia was particularly innovative in developing the "safe routes to school" program, which integrates education, route selection, and engineering treatments to increase pupil safety. Also in development is the "walk with care" program designed for the elderly.

The National Highway Traffic Safety Administration (NHYSA) began to evaluate its federal Motor Vehicle Safety Standards (FMVSS) in 1975. By October 2004, NHTSA had evaluated the effectiveness of virtually all the life-saving technologies introduced in passenger cars, pickup trucks, sport utility vehicles and vans from about 1960 up through the later 1990's. A statistical model estimated the number of lives saved from 1960 to 2002 by the combination of these life-saving technologies. FARS data for 1975-2002 document the actual crash fatalities in vehicles that, especially in recent years, include many safety technologies. Using NHTSA's published effectiveness estimates, the model estimates how many people would have died if the vehicles had not been equipped with any of the safety technologies. In addition to equipment meeting specific FMVSS, the model tallies lives saved by installations in advance of the FMVSS, back to 1960, and by non-compulsory improvements, such as the redesign of mid and lower instrument panels. FARS data have been available since 1975, but an extension of the model allows estimates of lives saved in 1960-1974. The annual number of lives saved grew quite steadily from 1960 to 2002, when most cars and light trucks were equipped with numerous modern safety technologies and belt use on the road.

Statistical analyses based on FARS and NASS CDS data from 1997 to 2009 found that a vehicle equipped with electronic stability control (ESC) had a smaller likelihood of being involved in a crash than a similar vehicle without ESC. This analysis estimates the magnitude of that reduction for different types of crashes and for different types of vehicles.

Work zone planning and management has become increasingly challenging because of increasing travel demand and an aging roadway network infrastructure facing both more frequent maintenance and major rehabilitation projects. Road-operating organisations across the nation are increasingly motivated to reduce congestion impacts resulting from road work, particularly on roadways where congestion is already a recurrent feature even before road work begins. This book provides a work zone analysis and work zone modelling and simulation from traffic analysis tools volumes.

This book may be of use to traffic engineers and researchers who are concerned with the conspicuity of traffic signs. The Manual on Uniform Traffic Control Devices advises that, "Signs should be placed on the right side of the roadway where they are easily recognised and understood by road users". Guidance is provided on the spacing and prioritisation of signs, and in some conditions, additional steps may be needed to ensure that signs are conspicuous. This book also provides federal regulations that have been put in place to ensure that traffic signs are visible at night, and discusses impacts on state and local agencies of maintaining traffic sign retroreflectivity.

This guidance is provided to assist transportation planners and environmental practitioners in the use of corridor and subarea planning to inform the National Environmental Policy Act (NEPA) review process. This document responds to the need for additional guidance on how best to use corridor and subarea planning to bridge the transportation planning and NEPA processes as described in Appendix A to 23 Code of Federal Regulations (CFR) Part 450 - Linking the Transportation Planning and NEPA Processes.

This publication will introduce you to materials, criteria, and procedures for rapid repair of uncontrolled cracks and spalls in rigid pavements by using epoxy resin grouts, mortars, and concretes. Seven crack conditions that encompass most of the crack types that will be encountered will be discussed. This course is applicable to the repair of rigid pavements on roads and airport runways and taxiways.

The Manual on Uniform Traffic Control Devices, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public traffic. The MUTCD is published by the Federal Highway Administration (FHWA) under 23 Code of Federal Regulations (CFR), Part 655, Subpart F. The MUTCD, which has been administered by the FHWA since 1971, is a compilation of national standards for all traffic control devices, including road markings, highway signs, and traffic signals. It is updated periodically to accommodate the nation's changing transportation needs and address new safety technologies, traffic control tools and traffic management techniques. On May 14, 2012 final rules adopting Revisions 1 and 2 of the 2009, MUTCD were published in the Federal Register with an effective date of June 13, 2012. These are also included in this manual

This report was one in a series of pedestrian safety synthesis reports prepared for the Federal Highway Administration (FHWA) to document pedestrian safety in other countries. This review reports research in six areas of pedestrian safety: 1) Interventions to prompt pedestrians to watch for turning vehicles. 2) Improving pedestrian signals for better indication of clearance interval. 3) Use of pedestrian-activated beacons at uncontrolled crossings. 4) Use of advance stop lines. 5) Increasing conspicuity of crosswalks. 6) Use of multiple interventions to increase motorist yielding to pedestrians. Research results are presented and a comprehensive list of references is provided.

Federal Motor Vehicle Safety Standard 214, "Side Impact Protection" was amended to assure occupant protection in a 33.5 mph crash test and phased-in to new passenger cars during model years 1994-1997. A Thoracic Trauma Index, TTI(d) is measured on Side Impact Dummies seated adjacent to the impact point. Manufacturers upgraded side structures and affixed padding in cars to improve TTI(d). Later, they installed two types of side air bags - torso bags and head air bags - for additional occupant protection in cars and LTVs. This report provides statistical analyses of 1993-2005 crash data from the Fatality Analysis Reporting System (FARS) and the General Estimates System (GES) estimate fatality reductions for these technologies.

Electronic Stability Control (ESC) is a safety technology designed to enhance a vehicle's stability and control in all driving situations ESC first became available in the United States in 1997 Statistical analyses of 1997-2004 crash data from the Fatality Analysis Reporting System (FARS) and 1997-2003 crash data from the State data files estimate reductions with ESC for various types of crash involvements

On February 16, 2012, about 8:15 a.m., near Chesterfield, New Jersey, a Garden State Transport Corporation 2012 IC Bus, LLC, school bus was transporting 25 students to Chesterfield Elementary School. The bus was traveling north on Burlington County Road (BCR) 660, while a Herman's Trucking Inc. 2004 Mack roll-off truck with a fully loaded dump container was traveling east on BCR 528, approaching the intersection. The bus driver had stopped at the flashing red traffic beacon and STOP sign. As the bus pulled away from the white stop line and entered the intersection, it failed to yield to the truck and was struck behind the left rear axle. The bus rotated nearly 180 degrees and subsequently struck a traffic beacon support pole. One bus passenger was killed. Five bus passengers sustained serious injuries, 10 passengers and the bus driver received minor injuries, and nine passengers and the truck driver were uninjured. Major safety issues identified in this investigation were school bus driver fatigue, sedating prescription medications, medical conditions, and commercial driver's license medical examinations; truck driver speed, oversight of overweight commercial vehicles, brake maintenance, and final stage manufacturing air brake system installation; connected vehicle technology; and school bus occupant injuries and school bus crashworthiness. The National Transportation Safety Board makes recommendations to the Federal Motor Carrier Safety Administration; National Highway Traffic Safety Administration; states of California, Florida, Louisiana, New Jersey, New York, and Texas; National Truck Equipment Association; National Association of State Directors of Pupil Transportation Services; National Association for Pupil Transportation; National School Transportation Association; School Bus Manufacturers Technical Council; National Safety Council, School Transportation Section; and Herman's Trucking Inc.

Another objective of this report is to add to the understanding of stormwater-runoff quality and quantity in an urban environment.

In SAFETEA-LU Section 1808, Congress required the U.S. Department of Transportation, in consultation with the Environmental Protection Agency (EPA), to evaluate and assess the direct and indirect impacts of CMAQ-funded projects on air quality and congestion levels to ensure the program's effective implementation. Phase II of the CMAQ Evaluation and Assessment responds to that request by exploring different practices and approaches that select agencies Nationwide use in CMAQ project selection and implementation. The study team conducted 1-day site interviews with Metropolitan Planning Organizations (MPOs) and State Departments of Transportation (DOTs) at seven locations around the country. The Phase II Report highlights effective CMAQ implementation practices and identifies benefits, challenges, and opportunities encountered by the agencies interviewed as they program CMAQ funds from the information collected and analyzed during the site visit interviews.
