The Atlanta metropolitan region was the location of one of the most ambitious Intelligent Transportation Systems (ITS) deployments in the United States. This deployment included several individual projects-a Central Transportation Management Center (TMC), six Traffic Control Centers (TCCs) one Transit Information Center (TIC), the Travel Informatio

The recently promulgated environmental regulations concerning volatile organic compounds (VOC) and certain hazardous heavy metals have had a great impact on the bridge painting industry. As a response to these regulations, many of the major coating manufacturers now offer "environmentally acceptable" alternative coating systems to replace those tra

Over 40 years ago, the United States embarked upon the largest public works project in its history--the construction of the Interstate highway system. The urban portions of this system along with the highways and public transportation services developed by state, county, and local governments, as well as public transportation services offered by ot

This report summarizes the lessons drawn from a series of twelve focus groups carried out in Fall 1996. The groups were conducted as an early stage of a larger project, undertaken on behalf of the USDoT Intelligent Transportation Systems Joint Program Office, to appraise the potential customer acceptance for key ITS products and services directed a

This Guide is about designing highways that incorporate community values and are safe, efficient, effective mechanisms for the movement of people and goods. It is written for highway engineers and project managers who want to learn more about the flexibility available to them when designing roads and illustrates successful approaches used in other

This report presents the measurement, data reduction and analysis of individual vehicle sound level and speed data for non-constant speed situations. These situations are referred to as interrupted flow conditions and include acceleration from stop signs, toll booths and on highway ramps. The measured noise levels were used to compute regression eq

The purpose of this publication is to provide local elected officials, business leaders, and community leaders with information on the congestion phenomenon and on the multimodal transportation strategies that can be used to provide improved mobility and accessibility.
The need for coordination and communication extends to the staffs of many organizations (e.g., police, fire and emergency services, and transit). These organizations must be able to share information, establish partnerships, and define the chain-of-command for incident management. ITS also provides for a link to be established and maintained with c

The New Jersey safety shaped barrier is one of the most common barriers currently in use on the Nation's highways. The barrier has successfully met all evaluation criteria set forth in National Cooperative Highway Research Program (NCHRP) Report 230. However, with the adoption of NCHRP Report 350 by the Federal Highway Administration (FHWA) as the

This document describes a procedure for resilient modulus quality control checks. The procedure evaluates the ability of laboratory personnel and the test system to complete LTPP P46 protocol for resilient modulus testing. The procedure is divided into three general phases: (1) Electronic System Performance Verification, (2) Calibration Check and O

The objectives of this study were to develop safer bridge rail and transition designs and to improve design guidelines. Ten bridge railings and two transitions were designed, tested, and evaluated in accordance with American Association of State Highway and Transportation Officials (AASHTO) requirements. The railings were designed using ultimate st

Recent contacts with truck and bus operators indicate that some, particularly smaller operators, are mistakenly assuming that if a driver possesses a Commercial Driver's License (CDL), he or she is a trained and experienced commercial vehicle driver. This is not true and can be a very dangerous mistake. All prospective employers of commercial drive

The Oregon side-mounted bridge railing consists of a 10-gauge thrie-beam mounted on W6x15 posts. A structural analysis of the railing indicates it will resist approximately 25 kips (111 kN) from a colliding vehicle. Full-scale crash tests demonstrated acceptable performance for performance level one of the 1989 AASHTO Guide Specifications for Bridg
