Book Synopsis The Effects of the All-red Clearance Interval on Intersection Accident Rates in Indiana by : Brian A. Roper
Download or read book The Effects of the All-red Clearance Interval on Intersection Accident Rates in Indiana written by Brian A. Roper and published by . This book was released on 1992 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research reported is an evaluation of all-red clearance intervals as the second phase of a project involving traffic signal operation. The first phase of the project dealt with leading versus lagging left turn signal phasing. The study analyzed both the short-term and long-term effects of all-red interval on accident rates in Indiana using accident records for the years 1981 to 1987. The results contradict those of previous studies. Statistical tests indicated that all-red clearance intervals did not cause a reduction in accident rates at the intersections studied in Indiana.

Book Synopsis Effectiveness of the All-red Clearance Interval on Intersection Crashes by : Molly McCarthy O'Brien

This book was released on 2003 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Crashes at signalized intersections account for approximately 20% of all crashes both nationally and within the State of Minnesota. Several research efforts have suggested that the use of all-red clearance interval at signalized intersections may reduce intersection crashes, particularly those related to signal violations. However, other research has shown that an all-red interval does not result in a reduction in crash rate. This research also evaluated the reduction in crashes due to use of an all-red interval at intersections within the City of Minneapolis. A cross-section analysis using generalized linear mixed models with a Poisson error distribution and log link function and mixed linear models with transformed data were used to compare Minneapolis sites with and without the all-red clearance interval. Results of the analysis agree with the previous studies that indicate no effect. A before and after analysis was also conducted to evaluate both short-term reduction in crash rate lasting approximately one year after implementation of an all-red interval. The research also evaluated user costs in the form of increased delay due to reduction in capacity that would result from implementation of the all-red interval at the remaining Minneapolis intersections that currently do not use the interval. Although a short-term effect was noted, the temporary safety benefits may not outweigh the long-term reductions in capacity and should be considered before implementation. Additionally, although no statistically significant long-term benefit was demonstrated, research results do not provide guidance on elimination of the all-red clearance intervals at intersections where it is currently in use.].

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to examine accident data at signalized intersections for accident patterns and trends that are susceptible to correction in Montana. The Scope of Work consisted of conducting a literature review, assimilating accident trend statistics, establishing variables of influence and determining significant causal patterns. Accident trend statistics were assimilated for the 3 year period from 1992 to 1994. The following variables were evaluated: type of accident, severity, alcohol involvement, roadway surface conditions, age of drivers, and contributing factors. Montana percentages for these variables were compared to other studies and were found to be similar. Accident trends between Montana's six largest cities (Billings, Great Falls, Missoula, Butte, Helena and Bozeman) were also investigated. Accident type percentages were similar for these cities. Accident rates were calculated along the State Primary Routes in Montana to establish variables of influence and significant causal patterns. Twenty five intersections were selected for further study, in which accident report files were obtained and collision diagrams were constructed. From these collision diagrams, relationships were investigated to determine trends for signalized intersections in Montana. Variables that were determined to affect accidents in Montana were traffic volume and population of the city in which the accidents occurred. Angle and rear end type accidents accounted for the largest percentages of accident types. When compared to other states and studies, accident characteristics in Montana are similar.

This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
