Speed Management


Book Description

This Report addresses the key issues surrounding traffic speed management and highlights the improvements in policy and operations needed to reduce the extent of speeding.







GIS-Based Accident Location and Analysis System (GIS-ALAS).


Book Description

This report summarizes progress made in Phase 1 of the GIS-based Accident Location and Analysis System (GIS-ALAS) project. The GIS-ALAS project builds on several longstanding efforts by the Iowa Department of Transportation (DOT), law enforcement agencies, Iowa State University, and several other entities to create a locationally-referenced highway accident database for Iowa. Most notable of these efforts is the Iowa DOT’s development of a PC-based accident location and analysis system (PC-ALAS), a system that has been well received by users since it was introduced in 1989. With its pull-down menu structure, PC-ALAS is more portable and user-friendly than its mainframe predecessor. Users can obtain accident statistics for locations during specified time periods. Searches may be refined to identify accidents of specific types or involving drivers with certain characteristics. Output can be viewed on a computer screen, sent to a file, or printed using pre-defined formats.

Ford Taurus Broadside Collision with a Narrow Fixed Object, FOIL Test Number: 95S008


Book Description

This report contains the test procedures, test setup and test results from a crash test performed at the Federal Outdoor Impact Laboratory (FOIL) located at Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia. The test was conducted by the Federal Highway Administration (FHWA) for the National Highway Traffic Safety Administration (NHTSA). The test involved a 1990 Ford Taurus four door sedan and the FOIL's instrumented rigid pole. The test was a broadside collision between the Ford Taurus and the FOIL's rigid pole at a nominal test speed of 35 km/h. The objective of the test was to provide the NHTSA with data to support validation efforts of passenger vehicle Finite Element Models (FEM). In addition to the validation support, the test was conducted to provide insight into the relative strength of a mid-sized sedan and the degree of occupant risk during a broadside collision with a narrow fixed object. A 50th percentile side impact dummy (SID) was used to measure occupant risk. Results from the test are presented as graphs of data from the transducers affixed to the test vehicle and dummy and photographs before and after the test. The data and high-speed test film provided support for the validation effort. The data shows that broadside collisions with narrow fixed objects cause high penetration which leads to an increased risk of occupant injury.




International Encyclopedia of Transportation


Book Description

In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications







Managing Speed


Book Description

TRB Special Report 254 - Managing Speed: Review of Current Practices for Setting and Enforcing Speed Limits reviews practices for setting and enforcing speed limits on all types of roads and provides guidance to state and local governments on appropriate methods of setting speed limits and related enforcement strategies. Following an executive summary, the report is presented in six chapters and five appendices.
