Available in PDF, EPUB and Kindle. Book excerpt: In addition to fatalities and injuries resulting from truck involved accidents, excessive costs and delays caused by these accidents and incidents have prompted several operating agencies to consider various strategies to reduce the truck accident/incident problem. This study was undertaken to identify truck accident countermeasures implemented in different areas of the U.S. Issues considered when selecting countermeasures for review in this study included urban freeway volumes of 95,000 vehicles per day or higher, a significant number of trucks in the traffic stream (typically 5% or more), and countermeasures involving road design. The study omitted countermeasures directly related to the vehicle and the driver. This project included the following steps: literature search, telephone survey, and field visits to selected sites. The information collected by this project is intended to assist agencies in identifying, selecting, and implementing truck accident countermeasures. Experiences with the following truck accident countermeasures are included in the report: lane restrictions, separate truck facilities, ramp treatments, truck diversions and bans, reduction of shoulder parking, urban truck inspection stations, incident response management, differential speed limit, increased enforcement, tall barriers, and mainlane treatments.

Book excerpt: Research into the types, severity and causes of crashes involving heavy vehicles in urban Australia was carried out and countermeasures were recommended to reduce the incidence and severity of such crashes. The project included literature review, mass data analysis, detailed post crashes analysis of fatal crashes, analysis of accident black spots and in depth investigation. The study found significant deficiencies in driver, rider and pedestrian behaviour which directly relate to the causation of severe crashes. The critical importance of the traffic engineering design of controlled and uncontrolled intersections has been highlighted. The design of heavy vehicles for operation in urban areas also needs improvement and measures to reduce heavy vehicle aggresivity and to redress deficiencies in the driver's field of view are needed.

Download or read book Crash Causal Factors and Countermeasures for High risk Locations on Multilane Primary Highways in Virginia written by Nicholas J. Garber and published by . This book was released on 2009 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2004, a total of 95,020 vehicle crashes occurred on highways under the jurisdiction of the Virginia Department of Transportation (VDOT). Of these, 39,847 crashes occurred on primary highways, and 345 of these were fatal crashes. VDOT's traffic engineers continue to place increasing emphasis on identifying causal factors for crashes to enhance the selection of appropriate and effective countermeasures. The purpose of this study was to identify causal factors and appropriate countermeasures for crashes occurring at high-risk locations on multilane primary highways from 2001 through 2006. These high-risk locations were identified by Fontaine and Reed (2006) in a VDOT safety corridor study. A total of 365 sites, 1 to 2 mi in length, were used in the study. The statewide sites were located on rural and urban highways with divided, undivided, and traversable medians, with about 40 sites per VDOT district. Crash data were extracted from police crash reports, and geometric data were collected through site visits. Operational data were collected using VDOT's resources. The analysis involved more than 34,000 crashes and was conducted using fault tree analysis and generalized linear modeling. The fault tree analysis was used to determine the critical fault path based on the probability of an event occurring. Individual fault trees were constructed for each collision type and for each highway classification. The generalized linear models were developed for different highway classifications: urban divided, urban undivided, urban traversable (central lanes that can be used for left turns in both directions), and rural divided highways. Models were developed for rear-end crashes and total crashes, and separate models were developed for injury crashes, property damage only (PDO) crashes, and injury + PDO crashes. Appropriate potential countermeasures were then identified based on the significant causal factors identified in the models. The results indicated that rear-end crashes were the predominant type of crash, representing 56% of all PDO crashes on urban divided highways and 37% of all PDO crashes on rural divided highways. Implementing the recommended countermeasures for total, rear-end, and angle crashes for different assumed levels of rehabilitation is expected to result in a crash reduction of up to about 40% depending on the site and level of rehabilitation undertaken. A benefit/cost analysis showed that the benefit/cost ratios were higher than 1 for all levels of countermeasure implementation.

Available in PDF, EPUB and Kindle. Book excerpt: House Joint Resolution No. 23, 2002 Session of Virginia's General Assembly, requested that the Virginia Transportation Research Council and the Crash Investigation Team of Virginia Commonwealth University's Transportation Safety Training Center conduct a study of highway crashes involving trucks and other large vehicles stopped on the roadway or shoulder and struck in the rear. The purpose of the study was to determine the spatial and perceptual factors, physiological elements, and ingredients that combine to cause or materially contribute to these crashes; how and why these crashes occur; and practical countermeasures to reduce the number and severity of these crashes. To answer the question of how and why these crashes occur, Virginia crash data from 1997 through 2001 were analyzed. In only a few crashes was a large truck stopped on the roadway or shoulder struck in the rear by a passenger vehicle. Rear-end crashes in which the leading vehicle was stopped were more numerous, but single-vehicle roadway departure crashes into parked vehicles were more severe. Environmental, roadway, and surface conditions had little influence. The major contributing factor was driver inattention. With regard to the psychological and perceptual factors contributing to these crashes, it is likely that large trucks are more conspicuous than other stopped vehicles because of their size, unique profile, and requirements for reflectorized tape. However, large trucks stopped or parked continue to be struck in the rear by passenger vehicles. The cause here is also driver inattention in several forms, none of which can be directly attributed to any particular crash without a detailed crash investigation. As to possible countermeasures, two approaches stand out: increasing driver attention and removing large trucks from the shoulder. Existing methods for increasing driver attention include using infrastructure warning systems and continuous shoulder rumble strips. Future improvements to driver attention are linked to technically advanced collision warning systems that will enter the marketplace before 2012 and provide an automatic warning to drivers of possible collisions. Removing large trucks from the shoulder is more of a problem and is tied to the larger issue of the supply and demand for public and private commercial vehicle parking. Short-term improvements include amending and strictly enforcing existing parking regulations, developing a pilot program to alert truck drivers of available parking facilities, and investigating the use of Virginia's weigh stations for large truck parking. The long-term approach includes conducting studies designed to document the extent of large truck parking on the ramps and shoulders of Virginia's limited access highways, assessing the adequacy of large-truck parking statewide, and prioritizing locations with the greatest need for public and private development of large-truck parking facilities.
