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.

The guide focuses on how agencies can implement Transportation Asset Management (TAM). The short brochure defines TAM as “a strategic and systematic process of operating, maintaining, upgrading and expanding physical assets effectively throughout their lifecycle.” The brochure then discusses the benefits of TAM and enumerates the steps to implement TAM.

This guide is intended to assist environmental agencies better understand the Lean methods and the correct usage of each method. It focuses on Lean production, an organizational improvement philosophy that allows agencies to reduce waste in government processes.

Alaska DOT & PF seeks to develop their agency's asset management maturity in order to improve the life cycle management and performance of their resources. The TAMP addresses a desire to more effectively use rich collections of data, fill gaps in data and understanding of performance, and change organizational procedures and culture. This TAMP outlines a work plan for the timeframe of 2012-2014, composed of self-contained projects for the advancement of the agency's current practice.
