Book Description
Creating Resilient Transportation Systems: Policy, Planning and Implementation demonstrates how the transportation sector is a leading producer of carbon emissions that result in climate change and extreme weather disruptions and disasters. In the book, Renne, Wolshon, Murray-Tuite, Pande and Kim demonstrate how to minimize the transportation impacts associated with these urban disasters, with an ultimate goal of returning them to at least status quo in the shortest feasible time. - Assesses the short and long-term impacts of transportation systems on the natural environment at local, regional and global scales - Examines transportation systems in relation to risk, vulnerability, adaptation, mitigation, sustainability, climate change and livability - Shows how urban transportation investments in transit, walking and bicycling result in significantly lower per capita carbon emissions when compared to investing in sprawling, automobile dependent regions

Book Description
The Virginia Department of Transportation (VDOT) currently uses snowplowable raised pavement markers (SRPMs) to supplement longitudinal pavement markings on some facilities. SRPMs are much more visible than traditional longitudinal markings under wet, nighttime conditions. SRPMs have been reported to dislodge from pavement, however, which has raised the question as to whether alternative marking materials might be able to replace SRPMs. The purpose of this study was to investigate the visibility performance of longitudinal pavement marking materials currently on the market. The specific objectives of this study were (1) to determine whether or not new pavement marking materials could be used in place of SRPMs; (2) if SRPMs were to be used, to develop guidelines for their installation and maintenance; and (3) to determine the costs and benefits of using SRPMs to the maximum extent possible. No new data on the visibility or durability of pavement marking materials were collected for this study. The study primarily synthesized existing research on the characteristics of different marking materials and then applied information derived from the synthesis to Virginia-specific data to estimate the impacts of using different materials. National practices for installing, inspecting, and maintaining SRPMs were also reviewed. The results of the literature review indicated that SRPMs remain the only marking system that provides sufficient nighttime preview time at high speeds, especially under wet conditions. Further, SRPMs can improve safety in certain situations, but they can also degrade safety in other situations since drivers may travel at higher speeds when the distance they can see down the road at night increases. Proposed guidelines for the installation and maintenance of SRPMs were developed. They recommend that SRPMs be installed on all limited access freeways, on all two-lane roads with an average daily traffic volume above 15,000 vehicles per day, and on all roads with a posted speed limit of 60 mph or greater. Several other situations where SRPMs might be installed based on engineering judgment were also identified. A proposed maintenance schedule that requires inspections every 2 to 3 years was also developed. A conservative economic analysis indicated that the benefits of installing and maintaining SRPMs using the guidelines developed in this study outweighed the costs by more than 80 to 1, based purely on potential safety improvements on road geometries where SRPMs have been shown to improve safety. Further, VDOT can realize cost savings by discontinuing SRPM usage on low-volume facilities and by revising particular SRPM standards.

Book Description
This synthesis report will be of interest to state, local, and federal agency environmental and maintenance administrators, directors, supervisors, engineers, and scientists. It describes current best management practices (BMPs) for environmental issues related to road and street maintenance. The synthesis documents relevant background and recent information with regard to management practices that can help protect, preserve, or enhance the environment while at the same time allow road maintenance organizations to carry out their fundamental mission of maintenance and repair in a cost-effective manner. Information for the synthesis was collected by surveying U.S. and Canadian state and local transportation agencies and by conducting a literature search using domestic sources. This report of the Transportation Research Board describes BMPs consisting of broad management approaches applicable to the entire maintenance program or to more than one program area. In addition, BMPs for specific maintenance activities or groups of maintenance activities are included. Finally, BMPs concerning specific environmental issues are discussed.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 525, Vol. 16: A Guide to Emergency Response Planning at State Transportation Agencies is designed to help executive management and emergency response planners at state transportation agencies as they and their local and regional counterparts assess their respective emergency response plans and identify areas needing improvement. NCHRP replaces a 2002 document, A Guide to Updating Highway Emergency Response Plans for Terrorist Incidents. NCHRP Report 525, Vol. 16 is supported by the following online appendixes: Appendix K - Annotated Bibliography; Appendix L - White Paper on Emergency Response Functions and Spreadsheet Tool for Emergency Response Functions; Appendix M - 2010 Guide Presentation. NCHRP Report 525: Surface Transportation Security is a series in which relevant information is assembled into single, concise volumes - each pertaining to a specific security problem and closely related issues. The volumes focus on the concerns that transportation agencies are addressing when developing programs in response to the terrorist attacks of September 11, 2001, and the anthrax attacks that followed. Future volumes of the report will be issued as they are completed.

Book Description
A multi-disciplinary approach to transportation planningfundamentals The Transportation Planning Handbook is a comprehensive,practice-oriented reference that presents the fundamental conceptsof transportation planning alongside proven techniques. This newfourth edition is more strongly focused on serving the needs of allusers, the role of safety in the planning process, andtransportation planning in the context of societal concerns,including the development of more sustainable transportationsolutions. The content structure has been redesigned with a newformat that promotes a more functionally driven multimodal approachto planning, design, and implementation, including guidance towardthe latest tools and technology. The material has been updated toreflect the latest changes to major transportation resources suchas the HCM, MUTCD, HSM, and more, including the most current ADAaccessibility regulations. Transportation planning has historically followed the rationalplanning model of defining objectives, identifying problems,generating and evaluating alternatives, and developing plans.Planners are increasingly expected to adopt a moremulti-disciplinary approach, especially in light of the risingimportance of sustainability and environmental concerns. This bookpresents the fundamentals of transportation planning in amultidisciplinary context, giving readers a practical reference forday-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning softwarepackages Get up to date on the latest standards, recommendations, andcodes Developed by The Institute of Transportation Engineers, thisbook is the culmination of over seventy years of transportationplanning solutions, fully updated to reflect the needs of achanging society. For a comprehensive guide with practical answers,The Transportation Planning Handbook is an essentialreference.
