Traffic Analysis Toolbox Volume XII: Work Zone Traffic Analysis-Applications and Decision Framework.

摘要

Work zones have significant impacts on the mobility and safety of transportation network. It is important to analyze and understand the anticipated extent and severity of work zone impacts associated with various project alternatives before implementing them. A work zone traffic analysis also enables practitioners to include appropriate mitigation strategies during project planning, design, and in the development of effective transportation management plans (TMP). This document is the third volume in the FHWA Traffic Analysis Toolbox: Work Zone Analysis series. The first volume provides guidance to decision-makers at agencies and jurisdictions considering the role of analytical tools in work zone planning and management, and the second volume provides specific guidance to the analyst, researcher, or manager in charge of conducting a specific work zone analysis project. This document, the third volume in the Work Zone Analysis series, focuses on key considerations when applying various modeling tools for work zone traffic analysis and provides a decision framework on how to select the best alternatives based on a set of performance measures. It serves as a useful resource for practitioners, researchers, or managers in understanding the analytical methods and decision framework involved in conducting a work zone traffic analysis. It contains step-by-step guidance on determining the most suitable tools to perform the work zone analysis. It also presents the essential components of a work zone traffic analysis report. To illustrate the process and decision framework contained in this document, a variety of case studies are presented to demonstrate a diverse set of work zone traffic analysis applications.
