Positive Guidance is a high payoff, short-range way to enhance safety of substandard facilities. This report presents three types of information to guide the user in applying Positive Guidance. Part I of this report discusses the principles, concepts and terminology underlying Positive Guidance. Part II presents the procedures for performing the eighteen activites required to accomplish Positive Guidance objectives. Part III presents three case studies to show procedure application and product variation brought on by site differences. The three case studies are urban, signalized intersection; interstate freeway segment; and, a rural two lane road.

Human Factors Guidance For Intelligent Transportation Systems At The Highway Rail Intersection

Human Factors Guidance For Intelligent Transportation Systems At The Highway Rail Intersection written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2006 with Highway-railroad grade crossings categories.

This document provides guidance recommendations and supporting material to assist designers and implementers of intelligent transportation system (ITS) applications related to highway-rail intersections (HRI). The guidance focuses specifically on roadway user human factors requirements associated with ITS as applied to HRIs. The guidance is intended to be of immediate help to practitioners but also to serve as a resource and impetus toward the development of consensus standards and other more formal guidance or specification. The document has four parts. Part I describes the purpose and scope and provides a human factors conceptualization of the roadway user. Part II provides an overview of ITS applications that have been implemented at HRIs. Part III presents general human factors guidance that cuts across various specific HRI applications, for topics such as message factors, roadside displays, in-vehicle displays, and displays for pedestrians. Part IV presents guidance for specific HRI applications, including train arrival warnings, advance information about the HRI, enforcement and control of vehicles, and light rail transit. Each guidance chapter provides background on the topic, an explicit statement of the major human factors issues, and a set of guidance recommendations (with accompanying rationale for each). This report includes over 130 guidance recommendations.

Evaluation Of Dynamic Speed Display Signs Dsds

Evaluation Of Dynamic Speed Display Signs Dsds written by Elisabeth R. Rose and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2003 with Roads categories.

Dynamic speed display signs (DSDS), devices that detect and display a vehicle's current speed back to the driver, have been shown to have a significant speed-reducing effect in temporary applications such as work zones or neighborhood speed watch programs. In this report, researchers examined the effectiveness of DSDS installed permanently in several locations that were experiencing speed-related problems. Seven sites were evaluated, including a school speed zone, two transition speed zones in advance of a school speed zone, two sharp horizontal curves and two approaches to signalized intersections on high-speed roadways. Data were collected before the DSDS were installed, about one week after installation to determine initial effects of the signs upon vehicle speeds, and again about four months after installation to determine how well the initial speed reductions were maintained. Researchers analyzed average speeds, 85th percentile speeds, percent of the sample exceeding the speed limit and standard deviations of the samples. Also, least square regression analyses between the speed of a vehicle upstream of the DSDS and that vehicle's speed measured again at the DSDS were performed to determine whether the sign affected higher speed vehicles more than lower speed vehicles. Overall, average speeds were reduced by 9 miles per hour at the school speed zone. Elsewhere, the effect of the DSDS was less dramatic, with average speeds reduced by 5 mph or less, depending on the location tested. As expected, the influence of a DSDS was found to differ depending on how fast a motorist approached the DSDS. Those motorists traveling faster than the posted speed did appear to reduce their speed more significantly in response to the DSDS than did motorists traveling at or below the posted speed limit. The results of this project suggest that DSDS can be effective at reducing speeds in permanent applications if appropriate site conditions apply.
