Human factors of in-vehicle driver information systems an executive summary by Peter Green( Book )

4 editions published between 1995 and 1997 in English and held by 112 WorldCat member libraries worldwide

This report summarizes a multiyear program concerning driver interfaces for future cars. The goals were to develop (1) human factors guidelines, (2) methods for testing safety and ease of use, and (3) a model that predicts human performance with these systems. After reviewing the human factors literature, focus groups were conducted to assess driver attitudes towards new information systems. Next, the extent to which these systems might reduce traffic accidents, improve traffic operations, and satisfy driver needs and wants was examined. Based on that effort and contract requirements, five functions were selected for further evaluation - route guidance, traffic information, road hazard warning, cellular phone, and vehicle monitoring

Methods for predicting truck speed loss on grades by T. D Gillespie( Book )

4 editions published between 1985 and 1987 in English and held by 106 WorldCat member libraries worldwide

Truck speed loss on grades reduces highway capacity and increses the risk of accidents. The rational design of a truck climbing lane as a solution to this problem requires means for predicting truck speed changes on grades. Experimental measurements of the speed loss of trucks operating on highways were conducted at 20 sites throughout the country. These data were analyzed to compare performance to present guidelines for highway design embodied in the AASHTO Policy on Geometric Design of Highways and Streets. The performance of the straight truck and tractor-trailer population is notably better than reflected in the AASHTO publication. Methods were developed for modeling the hill-climbing performance of the four major truck classes at the 12.5 and 50 percentile population level using empirically determined weight-to-power values. Speed-distance plots are provided for each class on constant grades, along with a simple computer program for calculating speed versus distance on arbitrary grades defined by the user
Short-haul trucks and driver fatigue final report by Dawn L Massie( Book )

3 editions published in 1997 in English and held by 103 WorldCat member libraries worldwide

This report has two main objectives. The first is to present data that may be used to create a definition of short-haul trucks in computerized data files. The second is to examine the prevalence of driver fatigue as coded in crash data files and relate it to parameters that define short-haul trucking operations. Tabulations were made of the numbers of large trucks registered in the United States and their annual travel using data from the 1992 Truck Inventory and Use Survey. Truck crash statistics were derived from the 1991-1993 Trucks Involved in Fatal Accidents file and, to a lesser extent, 1995 SafetyNet data. These tabulations were cross-classified by gross vehicle weight rating (GVWR) class, area of operation and vehicle type, and crash involvement rates per truck and per mile were generated. Three possible definitions of short-haul trucks are proposed and the different definitions are compared in terms of percentage of registered trucks and miles traveled, fatal crash involvements, fatal involvement rates per truck and per mile, and prevalence of fatigue-related fatal crash involvements. The results may assist others in making decisions about hours of service regulations for the short-haul segment of the trucking industry

Direct observation of safety belt use in Michigan : Fall 2000 by David W Eby( Book )

23 editions published between 1998 and 2005 in English and held by 38 WorldCat member libraries worldwide

A direct observation survey of safety belt use in Michigan was conducted in the fall of 2004. In this study, 13,874 occupants traveling in four vehicle types (passenger cars, sport-utility vehicles, vans/minivans, and pickup trucks) were surveyed between September 2 and 20, 2004. Belt use was estimated for all commercial/noncommercial vehicle types combined (the statewide safety belt use rate) and separately for each vehicle type. The current survey was designed to provide data for comparison with surveys conducted in previous years, as well as to provide follow-up data for comparison with the baseline survey conducted in August 2004. Within and across each vehicle type, belt use by age, sex, road type, day of week, time of day, and seating position were calculated. Statewide belt use was 90.5 percent. This rate represents the highest level of statewide safety belt use ever observed in Michigan. Further, this level of belt use makes Michigan only the fifth state in the country to obtain a statewide rate of 90 percent or higher. When compared with the baseline survey, a statically significant increase in overall belt use is noted. Safety belt use was 91.3 percent for passenger cars, 92.3 percent for sport-utility vehicles, 91.3 percent for vans/minivans, and 85.3 percent for pickup trucks. For all vehicle types combined, belt use was higher for females than for males, and about the same for drivers and passengers. In general, belt use was the highest during the morning commute and about the same throughout the rest of the day. Belt use did not vary systematically by day of week. Belt use was lowest among 16-to-29 year olds, and about the same for the 30-to-59 and 60-and-older age groups. Survey results suggest that the implementation of primary enforcement along with other enforcement and public information and education efforts have been effective in maintaining and continuing to increase safety belt use in Michigan

Evaluation of North Carolina crash data reported to MCMIS crash file by Anne Matteson( Book )

24 editions published between 2004 and 2008 in English and held by 21 WorldCat member libraries worldwide

This is one of a series of papers presenting the results of an evaluation of the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. Earlier studies showed that reporting to the MCMIS Crash File was significantly incomplete. This report examines the sources of underreporting for the state of Michigan. In 2003, there were 5,911 crash involvements in Michigan that were reportable to the MCMIS Crash file. 4,926 involvements were reported for that year, for a reporting rate of 73.7%. 303 of the cases reported to the Crash file did not meet the reporting criteria. 92.4% of fatal involvements were reported, 73.1% of qualifying injury crash involvements, and 73.4% of crashes with a towed, disabled vehicle. Unlike many other states, in Michigan reporting officers are responsible to identify qualifying vehicles (trucks, buses, and vehicles placarded with hazardous cargo), but cases meeting the severity criteria are selected centrally. This system likely partially explains the overall pattern of underreporting. Underreporting also is related to the time of year, indicating delays in providing the data. Reporting rates also varied by jurisdiction, with larger communities with more cases having higher rates of underreporting. Data quality is also reviewed. In certain variables, data in the Michigan police report file differed from that in the Crash file for some cases. Some inconsistencies were also noted between cargo body and vehicle configuration in the police report file and in the MCMIS Crash file
Methodology for road roughness profiling and rut depth measurement by T. D Gillespie( Book )

4 editions published between 1987 and 1988 in English and held by 20 WorldCat member libraries worldwide

This document presents an overview of a profiling and rut depth project. The objectives were to (1) assess the capabilities that are needed to measure profile and rut depth at highway speeds, (2) develop a design tailored to minimize life costs of the system, (3) build the system for delivery to FHWA, and (4) validate the system. A system based on the IBM PC microcomputer was designed. With the exception of a signal conditioning unit, the system is constructed from commercial components. The software controls the measurement of road profile and rut depth, the viewing of the data, and daily checks of the hardware integrity. A prototype--presently known as the PRORUT system--was built and delivered to the FHWA
