This book was released on 2022-03-29 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, sets out requirements for travel time reliability within a performance-based planning process. The research includes an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. The report includes two succinct tables that describe requirements for person and freight trips for reliable transport, as well as a forecast of the year 2030 under alternative assumptions that may influence travel time reliability.

Download or read book Advanced Notification Messages and Use of Sequential Portable Changeable Message Signs in Work Zones written by and published by . This book was released on 2005 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, researchers document the results of a laptop-based human factors study of alternative formats of presenting advance notice work zone information on portable changeable message signs (PCMSs) and a Texas Transportation Institute (TII) driving simulator study of the ability of motorists to capture and process information on two PCMSs used in sequence to convey information about upcoming traffic situations. Based on the studies, researchers recommend that messages that require the display of calendar dates for future roadwork and other traffic control activities should utilize a message format consisting of the three-character abbreviation of the month (e.g., APR for April) in conjunction with the date. When future work activities span several days all in the same month, the month needs be noted only once in the message (i.e., APR 21-23) rather than repeating the month (i.e., APR 21-APR 23). The ITI driver simulator study results indicate the need to keep overall messages at or below the four-unit maximum recommended in existing guidelines. Researchers found that presenting five units of information on sequential PCMSs resulted in low comprehension rates, below what would be acceptable for highway applications. However, by keeping the message length to four units, it does appear that the use of sequential PCMSs will result in comprehension rates comparable to those obtained by presenting the same information at a single location on a large dynamic message sign (DMS), and is recommended as an acceptable formatting approach for TxDOT. Comprehension may be enhanced by repeating one of the units of information on both PCMSs.

This book was released on 2012 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's Airport Cooperative Research Program (ACRP) Report 70: Guidebook for Implementing Intelligent Transportation Systems Elements to Improve Airport Traveler Access Information provides descriptions, component details, and examples of how airport ground access information can be disseminated using various intelligent transportation systems (ITS) technologies. The guidebook contains tables to help airport operators determine the applicability of certain ITS strategies based on airport operational needs and airport size. The printed version of the report includes an interactive CD-ROM designed to help explore and evaluate the information needs of various airport traveler market segments and to identify ITS technologies that best meet the needs of the airport user. The CD-ROM also contains a decision support tool that allows users to identify appropriate methods of delivering airport traveler information based on the airport traveler market segment.

Download or read book Amber Alert Disaster Response and Evacuation Planned Special Events Adverse Weather and Environmental Conditions and Other Messages for Display on Dynamic Message Signs written by and published by . This book was released on 2005 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides the results of focus group studies and human factors laboratory studies to investigate issues related to America's Missing: Broadcast Emergency Response (AMBER) alerts, disaster response and evacuation (flooding, hurricane evacuation, and terrorist attacks), planned special events, and adverse weather and environmental conditions in order to design effective messages for display on dynamic message signs (DMSs). Focus group studies were conducted in six cities in Texas to obtain driver views of the above issues and to discuss driver information needs. The results of the focus group studies were used as the basis for more extensive human factors laboratory studies that were then conducted in six cities in Texas. The laboratory studies were administered using several different methods of participant interface including laptop computer programs, maps, card selection process, and a driving environment simulator. This report contains specific findings and recommendations concerning message design issues for DMSs for each of the topic areas identified.

Download or read book Development of Manuals for the Effective Use of Variable Message Signs Final Report written by John S. Miller and published by . This book was released on 1995 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive research effort to develop operator's manuals for variable message signs (VMSs) was undertaken to improve the operations of both portable and permanent (fixed-site) VMSs in Virginia. This report describes the development of two manuals, the Permanent VMS Operator's Manual and the Portable VMS Operator's Manual which will be published separately. These manuals were based on information obtained from the literature, VMS operators, and motorists. Issues addressed by the manuals include when a VMS should be used, where a portable VMS should be placed, and the design of the VMS message. The manuals are not simply a list of pre-defined messages. They are a series of concise modules guiding the operator through the thought process required to use a VMS effectively. The operator follows a logical decision tree from module to module, to achieve the best placement and best message for a VMS. Effective VMS use actually requires a complex thought process, despite the apparent simplicity of the messages. The manuals include essential material about VMS operation. Based on theoretical calculations and motorists' experiences, it is strongly recommended that a VMS use no more than two message screens. A single message screen is preferred. VMSs should be used only to advise drivers of changed traffic conditions and convey specific traffic information concisely. Due to limited information capabilities, VMSs should be used in conjunction with other means of communication such as highway advisory radio and static signs. Most importantly, it is crucial that credibility be maintained. Incorrect information can have extreme consequences in terms of VMS effectiveness.

Download or read book Human Factors Guidance for Intelligent Transportation Systems at the Highway rail Intersection written by and published by . This book was released on 2006 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
