The objective of this “Raising the Bar” document is to highlight some of the lean tools and techniques, which demonstrate a positive impact on Health, Safety and Well-being.

This webpage provides two summaries of results from Colorado DOT's improvement efforts in 2013.

Performance-based planning and programming (PBPP) refers to the application of performance management principles within the planning and programming processes of transportation agencies to achieve desired performance outcomes for the multimodal transportation system. The Guidebook has been designed to help State DOTs, MPOs, RTPOs, transit agencies, and other partner organizations understand: the key elements of a PBPP process and the relationship of these elements within existing planning and programming processes. The Guidebook is designed to highlight effective practices to help transportation agencies in moving toward a performance-based approach to planning and programming.

There are two generally accepted methods for evaluating performance of intersections in Delaware - a volume based measure using the critical movement summary method and a delay based method, most commonly done using simulation software like Synchro. Each provides unique indicators of the intersections "health", just like a patient with two vital signs. And in general, they are used separately. This research proposes to provide a new, hybrid measure of intersection performance using the two level of service (LOS) measures together.

This study examines pavement management models using data from the Oklahoma DOT. Using 16 years of data collected with the Deighton Total Infrastructure Management System (dTIMS), the current models for predicting pavement deterioration are examined, compared, and, if necessary, recalibrated using the real-world data. The study contains a spreadsheet-based tool for managing pavement which could be of interest to anyone looking to either implement a similar tool, or justify the expense of detailed pavement monitoring data.

This summary addresses the reference "Extreme Government Makeover: Increasing our Capacity to Do More Good", which discusses the lack of capacity with government agencies and how to improve this dilemma.

This article describes the financial failures of several highway tunnels in Australia. These tunnels were mostly privately held, but financial disaster resulted in them being taken under public receivership. The research focuses on how the tunnel finances were so insecure, and also suggests ways to avoid similar situations in the future. There is also a compendium of the nine tunnels examined.

This collection of documents includes an introduction and CIRIA guides for sustainability, Benefits Realization Management, construction and BIM, selecting a Lean consultant, and for client organizations.

This webpage summarizes the reference "We Don't Make Widgets" that discusses the three major myths that inhibit government agencies from continuous improvement.

This paper focuses on the importance of convincing those in funding positions to invest not only in infrastructure for general safety, but also to make improvements to protect against earthquakes. The report focuses on the challenges of convincing funders to prepare for events that may never occur during their lifetime, but have enormous potential for damage and loss of life. Although the paper was prepared by the California Department of Transportation and concerns only seismic earthquakes, the principles are applicable to any location that faces relatively uncommon but very large risks to their infrastructure and safety.

This report is a reference guide for analyzing the risks associated with bridge scour predictions. The areas studied included hydraulic, hydrologic, and uncertainties inherent in the models. Step-by-step procedure are listed for complex foundation systems and systems in channel conditions to assess scour factors. Tables of probabilities for various underlying conditions are included. The report is a technical report of interest primarily to engineers.
