Risk analysis plays a key role in the implementation of an architecture. Early definition of the situations, processes, or events that have the potential for impeding the implementation of key elements of the ITS National Architecture is a critical element to the success of that implementation. The focus of risk assessment for an architecture diffe

In January 1996, US Department of Transportation Secretary Federico Pena unveiled the Operation Timesaver initiative at the annual meeting of the transportation Research Board (TRB). The Secretary set a national goal of building and deploying an Intelligent Transportation Infrastructure (ITI) across the US to save time and lives and improve the qua

The purpose of this study is to crash test and evaluate new or modified roadside safety hardware and, where necessary, redesign the devices to improve their impact performance. The three major areas addressed in this study are the impact performance of bridge railings, transitions from guardrails to bridge railings, and end treatments for guardrail

This document is a sequel to a previous bibliography which was compiled by the authors in 1989 as the first part of their research on high performance concrete sponsored by the Strategic Highway Research Program of the National Research Council. The previous bibliography was based on an extensive literature search to identify gaps in the existing k

The need to update Portland's current travel demand system, which is based on a 1985 household survey, generated this study. In this report, the Portland Metropolitan Service District (Metro) is showcased as an example of innovative and comprehensive data collection. Portland is one of the first urban areas in the country to undertake a region-wide

This study evaluated the full cost of three modes of intercity transportation: air, highway, and high speed rail. The evaluation is done within the context of the California Corridor, connecting the Los Angeles Basin and the San Francisco Bay Area. The purpose of evaluating full cost is to compare the economic implications of investment in, or expa

This report identifies specific intermodal performance measures developed by 15 State departments of transportation. The performance measures are classified by goals and analyzed by frequency of use. The report discusses the role of performance measures in the transportation planning process and their relationship to intermodal management systems.

This manual has been developed to provide information and guidance to engineering staffs involved with project develop and design of highways. It identifies those standards, specifications, guides, and references approved for use in carrying out the highway and bridge design responsibilities in the Federal Lands Highway (FLH) Program. One primary g

This study examines the principal dterminants of the levels and changes in transit ridership for the U.S. transit operators over the 30 year period from 1960 to 1990. Transit ridership is represented by annual boardings. We would hav e preferred to have used liked trips for these analyses, but linked trip data are simply unavailable for mos to the

This second volume of the draft final report focuses on specialized travel trends in the Puget Sound panel data from 1989 through 1993. Trips were catagorized by purpose and mode, with each trip of each wave characterized by three variables: total trips, duration, and distance. The waves of the survey were conducted in 1989, 1990, 1992, and 1993. F

This paper summarizes travel trends in the United States and five regional areas for the period 1970-1995. Travel is summarized at the annual, monthly, weekly, and daily time scales. Data sources for this study included the annual automobile travel estimates included in the Table VM-2 from Highway Statistics and traffic count data from approximatel

A study was conducted of the availability and need for truck parking at public rest areas and private truck stops along the Interstate highway system. The goal of the study was to assess the supply, utilization, parking statutes and practices, and demand related to rest area parking at the state and national levels and, based on the findings of tha

Demonstration Project 89 on Quality Management was created to provide guidance on the use of practical and effective procedures to assure that the level of quality designed into the plans and specifications is actually achieved in the constructed product. One part of this effort is the distribution of a software package consisting of several intera

This is the ninth in a periodic series of reports issued by the Metropolitan Planning Division, Federal Highway Administration. Included in this issue are two final reports of recent research in the area of metropolitan transportation planning, specifically with regard to congestion management. The research behind both reports was sponsored by the

The goal of this handbook is to assist the transportation planner in using the 1990 Census to develop and calibrate local travel demand models. Often, collecting new data to complete the development of a local model is not an option. Therefore, planners must rely on existing data and previously completed models with little else to assist in model c

The annoying noise frequencies produced from the tire/pavement interaction on some (usually transversely tined) Portland Cement Concrete (PCC) pavements have concerned both residents living nearby and motorists traveling over them. A Technical Working Group (TWG) was formed to investigate the problem by conducting a review of previous research and
