This collection of documents includes the Lean project results for every project within the Wisconsin DOT Government Initiative. The topic areas of the projects include mobility, accountability, preservation, safety, and service.

A document summarizing a number of Lean initiatives undertaken by the Connecticut Department of Transportation. The individual summaries address the challenges, the initiatives, and the impacts observed and/or measured.

This research project produced a guidebook that provides a comprehensive framework for implementing TPM practices, assess current TPM capabilities and identify actions to improve upon those capabilities. It includes case studies and illustrative examples to demonstrate how performance management results in improved decision-making. The guide also has an assessment feature that provides results linked to clear practical actionable steps for state DOT leadership, management, and staff to enhance performance-management practices.

NCHRP Project 20-24(89) is intended to provide compelling research results to support effective decision making and inform public policy. The research being undertaken to present—in ways that are both readily understandable to a broad audience and defensible within the professional community—the role and value of transportation to the U.S. economy, by developing case studies of transportation’s part in representative industries or economic sectors. These studies will rely on available data and accepted analysis methods to produce meaningful information and present that information in ways that will resonate with stakeholders in the nation’s transportation system.

The goal of this study is to identify the best and most effective ways to collect element level data in a format and with specific procedures that will ensure quality data are obtained and subsequently used most effectively. Element level data are required to be collected to implement element level bridge inspection procedures by October 1, 2014 per the MAP 21.

The objective of the proposed pooled-fund project is to assess the feasibility of and demonstrate the use of Traffic Speed Deflectometer (TSD) for network level pavement structural evaluation for use in the participating state agencies' pavement management application and decision making.

The objectives of this research are to (a) Identify an injury scoring system for further consideration. Analyze the advantages and disadvantages of conventional injury scoring systems based on International Statistical Classification of Diseases and Related Health Problems (ICD) codes and KABCO. Document advantages and disadvantages of various definitions for a serious injury metric. (b) Develop a roadmap to assist states in developing and implementing an interim system to measure and report injury severity using accepted injury scoring systems based on ICD codes. The intent of the roadmap is to enable year-to-year performance assessment by states using a standard measure. At a minimum, the roadmap should document a workable process(es) for linking statewide crash and hospital discharge data. For states where complete crash and/or hospital discharge data do not exist, identify surrogate sources, such as trauma registries, or alternative measures, such as estimates, that can be used within the workable process as an interim step until the preferred process(es) can be implemented. Identify means to overcome technical, legal, political, financial, and other challenges to implementation and linkage of these state-based data systems. The states’ future performance assessments will yield at a minimum the number of serious injury crashes and the number of persons seriously injured in each state using a standardized definition. This step should lead to the ultimate outcome, which is a unified database as described further in (c). (c) Expanding on (b), develop a state-based framework to perform comprehensive linkage of records related to motor vehicle crashes resulting in serious injuries, and incremental steps and priorities for achieving the linkage. A direct linkage is strongly preferred but it is recognized that alternative linkage methods may be appropriate, so the framework should include methods to be used when linkage is unsuccessful. Records may include crash and citation records; pre-hospital (telematics, 911, EMS, etc.); hospital (ED/inpatient); disability; death (coroner, medical examiner, vital statistics); trauma registries; traumatic brain injury registries; and roadway and traffic inventories. The framework will provide for a comprehensive analysis and understanding of the factors associated with serious injuries before, during, and after the crashes, and the associated medical outcomes. This will allow for the development, implementation, and evaluation of countermeasures for serious injury crashes, and continuous system improvement.

The objective of this proposed project is to develop an on-line user friendly truck weigh in motion (WIM) data tool where it offers data quality review and control functions, data visualization capabilities and analysis, and data output controls to meet pavement design, freight analysis, and truck weight and load trend analysis.

The 2012 federal transportation authorization - the Moving Ahead for Progress in the 21st Century Act (MAP-21) - places several new performance measurement and reporting mandates, including arterial system performance, on state transportation departments. The Virginia Department of Transportation (VDOT) is also interested in further, detailed system-performance measurement, as reflected in its current business plan goals. This research project will support VDOT in achieving compliance with these MAP-21 mandates and in making more informed operations and resource-allocation decisions. Specifically, this study will focus on identifying candidate arterial-system performance measures and data needs; exploring details of corridor segmentation for analysis and reporting; assessing impacts of missing data on performance measures; and conducting pilot analyses to calculate measures from actual Virginia data.
