This sourcebook is organized into seven chapters. Chapter 1 reviews the goals of this work, provides background on GHG emissions in transportation, and lists the strategies reviewed. Chapter 2 summarizes key findings about the strategies and offers recommendations to the FHWA about providing guidance to DOTs and MPOs. The research methodology is presented in Chapter 3 and the role of land use is presented in Chapter 4. Finally, Chapters 5, 6, and 7 present reviews of transportation demand management strategies, transportation system management strategies, and vehicle improvement strategies, respectively.
In October 2008 The Federal Highway Administration contracted a study team to conduct a two-part study to assess technology for the measurement of travel times for trucks through the Otay Mesa international border crossing into the US. The primary goal was to evaluate the ability of one of two technologies to accurately record travel times through the border zone. The specific objectives of the project were to: (1) Assess the effectiveness of a technology for automated capture of travel time for vehicles crossing the border. (2) Gather historical travel time data over the period of one year. The results of the work are summarized in this Final Report.
Model Systems Engineering Documents for Adaptive Signal Control Technology Systems is intended to provide guidance for professionals involved in developing systems engineering documents covering the evaluation, selection and implementation of adaptive signal control technology systems.
This report provides the transportation community (including highway engineers, planners, NEPA practitioners) with digestible, transparent, regional information on projected climate change effects that are most relevant to the U.S. highway system. This information is designed to inform assessments of the risks and vulnerabilities facing the current transportation system, and can inform planning and project development activities.
The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), which was signed into law in August 2005, contained several provisions focused on streamlining the environmental review process. One of these provisions, Section 6002, allowed for State Department of Transportation (State DOT) funding of staff, at both Federal and State resource agencies, who are dedicated to working on State DOT projects on environmental streamlining and related planning activities. This report assesses trends in the use of these "funded positions" and provides recommendations to State DOTs and resource agencies to support more effective uses of funded positions. The report is based on a study conducted by the Federal Highway Administration (FHWA) Office of Project Development and Environmental Review with assistance from the Volpe National Transportation Systems Center (Volpe Center). The study consisted of two parts: (1) a literature review to assess the state of the knowledge about State DOT-funded positions and agreements, and (2) a series of interviews with participants in funded positions programs, including program managers at State DOTs and Federal and State resource agencies and individuals in those positions.
This report provides a guide for achieving a basic service model for traffic signal management and operations. The basic service model is based on simply stated and defensible operational objectives that consider the staffing level, expertise and priorities of the responsible agency. The report includes a Literature Review, which provides a review of the National Traffic Signal Report Card and Self- Assessment, case studies based on agency archetypes that provide an understanding of how agencies deliver traffic signal management services based on their resources and interviews with acknowledged leaders providing support for the basic service concept. A discussion of signal timing versatility in support of the role it plays in providing good basic service is included in the Appendix.
This report's purpose is two-fold. First, it documents the elements likely required to implement a carbon sequestration process tailored to state Departments of Transportation (DOTs). Findings are based on the challenges, key lessons, and preliminary results from New Mexico DOT's initial five months of implementing the Federal Highway Administration's (FHWA) Carbon Sequestration Pilot Program (CSPP). Although communication of the progress and outcomes should continue through the life-cycle of the pilot program, it is expected that the body of knowledge formed from NMDOT's early experience can help other state DOTs evaluate the viability of carbon sequestration practices in lands they control. The CSPP is also considered a demonstration project. As such, this report offers preliminary recommendations and considerations that can assist FHWA and other federal agencies in making well-informed decisions related to carbon sequestration in highway ROW during discussions surrounding the reauthorization of the nation's next transportation bill. Since the NMDOT effort is ground-breaking nationally, and perhaps globally, it is expected that NMDOT's experience can provide insights useful in determining whether efforts to accomplish a similar program at a broader scale are practical.
For this exploratory study, focus groups were convened in Northern Virginia and Philadelphia among the general public, business owners and managers, and owners and managers of shipping and transportation logistics firms. The purpose of these focus groups was to obtain feedback on a specific congestion pricing scenario and to better understand the public's concerns regarding congestion pricing. A secondary purpose was to learn more about how to communicate with the public on the topic of congestion pricing.
The objective of this review is to develop a marketing plan of the most effective methods of promoting bicycle and pedestrian safety to Hispanic audiences.
In March 2000, FHWA, AASHTO and the Transportation Research Board (TRB) jointly sponsored an international scanning study to observe right-of-way and utility coordination practices in four European countries. The scanning study delegation identified practices used in the selected countries that, if implemented in the U.S., will help ensure timely procurement and clearance of highway right-of-way and adjustment of utilities. Findings and observations in this report are grouped into the following chapters (Appraisal and Acquisition; Compensation and Relocation; Training; Utilities; and Project Development) and includes primary findings the team believes have the most significance and/or implementation value. Other observations that may have potential implementation value in the United States are also included.
In March 1998, the Federal Highway Administration (FHWA) Office of Natural Environment, released the FHWA Traffic Noise Model (FHWA TNM) Version 1.0, a state-of-the-art computer program for highway traffic noise prediction and analysis. Since then, the FHWA, with assistance from the Volpe Center Acoustics Facility (Volpe Center) and Foliage Software Systems (FSS), have released updates of TNM (Versions 1.0a, and 1.0b) in March 1999 and August 1999, respectively. In support of the FHWA and the California Department of Transportation, the Volpe Center and FSS released Version 1.1 in September 2000. TNM 2.0 is the latest release of the TNM software. Two companion reports were released with TNM Version 1.0, a Technical Manual that describes the acoustics within TNM and a User's Guide. In addition, prior to TNM release, a data report was published that describes the vehicle noise-emissions data base within TNM. This document is an addendum to the FHWA TNM Version 1.0 User's Guide. It details the enhancements in the program up to and including Version 2.0.
This summary report describes the September 1998 technology transfer scan tour to four European countries to learn how these countries are addressing their own safety issues, even as they comply with the increasing centralization of rules and regulations enacted by the European Commission. The key areas examined were human resources, vehicle safety systems, and regulations. The report includes recommendations and implementation strategies.
The objectives of this document are to provide: (1) guidelines on how to design a highway noise barrier that fits with its surroundings and performs its intended acoustical and structural functions at reasonable life-cycle cost; and (2) a state-of-the-art reference of common concepts, designs, materials, and installation techniques for the professional highway engineer, the noise barrier designer, and the non-professional community participant.
