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.

This tool provides information and guidance on the Define, Measure, Analyze, Improve and Control methodology. This methodology assists lean project teams' activities by identifying and eliminating variation in a process.

This tool is a checklist for the major elements needed to implement a successful Lean Rapid Improvement Event.

This exercise was originally created by the Minnesota Office of Continuous Improvement as a standard work tool for Lean methodology.

This tool provides all of the Colorado DOT's Lean Everyday Ideas from 2012 to present. These Everyday Ideas are front-line improvements that Colorado DOT has implemented with Lean methodology.

This tool includes a recorded webcast and slides originally presented by LeanOhio on the state's continuous improvement efforts.

This online tool is designed to help agencies minimize risk on roadways. The tool provides a list of potential risk factors, as well a step-by-step system to implement safety planning. The focus is primarily on systemic improvements, rather than focusing on risks at specific locations, although the tool does consider the necessary balance between sport-improvements and improvements that are system-wide. Case studies provided include: Illinois, Kentucky, Louisiana, Minnesota, Missouri, Nebraska, New York, Ohio, and Thurston County, WA.

This executive summary is a report on a US scan team that visited several international agencies in July and August of 2009. The visited agencies were: Swedish Road Administration, the UK department of Transport and Highway Agencies, the New South Wales Roads and Traffic Authority and Austroads, the Victoria Department of Transport and VicRoads, the Queensland Department of Transport and Main Roads and the New Zealand Transport Agency. The team looked at how strategic goals were actual implemented by the agencies, how performance goals were achieved, how performance and transparency were linked, and how agencies can demonstrate accountability.

This synthesis reports on the maintenance and replacement of light-emitting diode (LED) traffic signal modules. It suggests some successful practices to deal with the complexities of the new and evolving LED technology and concludes with suggestions for additional research to resolve outstanding technical issues. It is intended for those currently dealing with the technicalities of evolving LED technology. Although experience is building, LED traffic signals remain an improving product and the uncertainties in the life of LEDs from an economic, performance, and safety perspective are not well understood. This is natural given the nature of LED technology; nevertheless, uncertainties associated with these issues are a major impediment to the development of a sustainable replacement strategy. As the topic panel directed, this synthesis includes the results of a 2006 ITE Task Force survey effort of users and vendors/manufacturers of LED modules. The specific objectives of the synthesis are to familiarize readers with the history of LEDs as replacements for incandescent lamps, to facilitate an understanding of LED issues, to document lessons learned, and to present successful practices in order to minimize future problems. ITE survey information presented includes 75 responses from public agency traffic engineers, consisting of ITE public agency members and AASHTO state traffic engineers, and 6 LED vendors/manufacturers [members of the National Electrical Manufacturers Association (NEMA)]. These survey responses were supplemented by follow-up discussions with various state agency officials who confirmed the initial survey results. A case study details more specific LED information gleaned from the Road Commission of Oakland County, MI's experience with LEDs dating back to 2000.

This presentation focuses on clear and concise communication of asset management principals to stakeholders. The presentation goes through a number of strategies and tips for communication with stakeholders and The second half of the presentation includes alternative ways of reaching stakeholders such as brochures, videos, and interactive activities.

This document summarizes the recommendations of the TAM ETG for the type of support needed to advance the implementation of asset management in State transportation agencies in the future. The recommendations include an endorsement for continuing the work of the TAM ETG as a source of on-going feedback and support to FHWA, AASHTO, and TRB as these agencies develop strategy, policy, technical guidance, and implementation actions related to asset management.
