TRB’s second Strategic Highway Research Program 2 (SHRP 2) Report S2-C06-RW-2: An Ecological Approach to Integrating Conservation and Highway Planning, Volume 2 is designed to help transportation and environmental professionals apply ecological principles early in the planning and programming pro
This guidebook provides information on how to create an objectives-driven, performance-based congestion management process. While the focus of this guidebook is on the CMP, the principles of objectives-driven, performance-based planning can also be applied to other aspects of regional concern (sa
TRB’s second Strategic Highway Research Program (SHRP 2) Reliability Project L07 has released a prepublication, non-edited version of an Analysis Tool for Design Treatments to Address Nonrecurrent Congestion: Annotated Graphical User’s Guide Version 1.0. The guide is intended to assist users of t
This section describes TIM AMS methods and related applications. In each of the following subsections the current state of the practice is documented. The state of the practice (what is in current use) is discussed separately from the state of the art (that what has been researched).
Traffic incidents are a major source of congestion in both urban and rural areas. Nationally, roughly 25 percent of total congestion is due to traffic incidents. Further, traffic incidents create unexpected congestion – congestion that occurs in times and places where travelers don’t expect
A webinar presentation on project L03 processes and findings.
This report discusses the application of travel time data and statistics to travel time reliability analyses. It covers topics such as data sources for reliability, data processing methods, case studies comparing reliability measures, and the conclusions drawn from the analysis. The page includes
This primer offers transportation planners and operations managers a menu of opportunities for applying the regional ITS architecture to enhance planning for operations. Because many TSM&O strategies are underpinned by ITS, the coordination of planning for ITS among agencies at the institutio
This primer contains information and opportunities for incorporating the regional ITS architecture to enhance planning for operations. It focuses on the use of an objectives-driven, performance-based approach to planning for operations. The primer guides planners and operators through ways to inc
A critical element in improving transportation decision-making and the effectiveness of transportation systems related to operations and planning is through the use of analysis tools. The use of the term “Tools” in this context is meant not only to include physical software and devoted analytical
