WISE, WORKZONE IMPACT AND STRATEGY ESTIMATOR SOFTWARE (R11)

Software to analyze the impacts on road users of multiple, concurrent work zones across a network or complex corridor. Users guide.
This tool will help agencies assess the optimal sequencing of renewal projects, and help determine the cost-effectiveness of strategies to minimize, manage, and mitigate road user costs from safety or operational perspectives.
The WISE software is fully developed and is being tested in Iowa and Arizona using historical data to validate its parameters. In addition, pilot tests in New York and Florida will use the software to analyze projects currently in the planning phase.

The report, users guide, and software are available at www.trb.org/Main/Blurbs/168143.aspx.

Program managers within DOTs and metropolitan planning organizations (MPOs) are charged with distilling a chaotic universe of identified infrastructure renewal needs into a logically sequenced program of manageable projects over a period of years. In addition, program managers must sequence programs of projects in ways that maximize available resources, minimize disruptions to the traveling public and to adjacent land uses, and recognize political priorities. Over the past several years, substantial progress has been made in the areas of performance measurement, maintenance of traffic, mitigation of congestion in work zones, and alternative contracting and construction techniques. This work was designed to minimize, manage, and mitigate disruption to traffic and commerce arising from infrastructure renewal programs. In application, however, performance measures are applied largely at the project level and impacts are not analyzed at the program level.

This project had five objectives:

   1. Identify and document effective practices for executing highway renewal activities as they affect the corridor and network level;
   2. Identify instances and examples of the transportation agency and project organizational designs that are most and least compatible with these effective practices;
   3. Identify and develop new dynamic tools, techniques, and processes to help public agencies execute highway renewal activities at the corridor and network levels and measure risks from the perspective of constructability, funding, economic/environmental/social constraints, and congestion and safety impacts;
   4. Provide guidance for selecting appropriate tools, techniques, performance measures, and practices during project development; and
   5. Assess and develop training needs and materials and knowledge transfer methods for implementation.

This project developed a software tool capable of evaluating the strategic impact at the regional or large corridor level of constructing renewal projects and programs. Existing work zone related software and evaluation tools were reviewed and the best aspects were incorporated in the development of the Work Zone Impact and Strategy Estimator (WISE) tool. Using WISE, a program manager can assess the impacts of a renewal program and compare different sequencing scenarios of projects, in light of desired performance objectives. This tool is intended to create a more fully informed decision-making process regarding program sequencing and allocation of limited resources.

WISE can evaluate the regional impact of various infrastructure renewal strategies, such as day/night operations, innovative contracting, rapid construction techniques, advanced maintenance of traffic plans, and public information programs. Evaluations can be conducted at both the planning and the operational level. When used as a planning tool, WISE develops an optimized renewal programming schedule that minimizes delays to the public and agency cost. When used at the operational level, it evaluates the impact of individual strategies at the project level; the results can then be used as part of an iterative procedure with the planning analysis. WISE does not require the use of proprietary software; it builds on existing travel demand software used by DOTs and MPOs.

Project Status: This project is active.

Product Availability: The final report, the WISE user guide, and the WISE software are available on the TRB website at: http://www.trb.org/Main/Blurbs/168143.aspx. The training materials will be available in 2013.
