This presentation from the September 2016 Transportation Lean Forum includes detailed presentations on Lean Transformation, Organizational Excellence Task Force, Bureau of Innovations, and Lean Interchange forum updates.

This video from the Idaho Transportation Department describes an innovative signal light best practice that allows practitioners to maintain and repair signal lights efficiently.

This Desk Reference is designed to equip State, regional, and local transportation operations and planning professionals with the knowledge and tools necessary to effectively plan for and implement transportation systems management and operations (TSMO) within a corridor. Its purpose is to support transportation planners and operations staff to plan for and apply TSMO activities within corridors to achieve a more reliable, efficient, and livable outcome from their existing and planned transportation infrastructure. This document highlights a planning for operations approach at a corridor level to focus on issues, such as mobility, reliability, and safety, from a multimodal perspective and provides a variety of tools to advance TSMO within corridors.

This document provides an explanation of the steps taken to develop the risk register tool. The research team conducted a survey of current practices for risk management across state DOTs, international agencies, and non-transportation organizations. Then they built a draft tool and received user feedback before finalizing the tool.

As more agencies are collecting data from various different roadside sensors, the need for data anonymizing is increasing. This report describes several methods for safely anonymizing data that protects the privacy of transportation system users without minimizing the data's value to practitioners.

Pennsylvania's multimodal long range plan incorporates performance-based planning and includes freight movements in addition to all other modes of transport. This document focuses on three sections, project prioritization, projects, and system performance with sections covering transportation context, multimodal needs, strategies, revenue and funding, and future challenges.

This TechBrief presents the methodologies and procedures used by the research team in the analyses of the Long-Term Pavement Performance (LTPP) data to develop and implement pavement performance measures and to analyze treatment effectiveness. The LTPP study focused on using data from the various LTPP experiments to define pavement performance in a way that supports the selection of cost-effective pavement treatment strategy and to better estimate pavement treatment effectiveness and the role of pavement treatments in the pavement’s lifecycle. This TechBrief includes a description and examples of the dual pavement condition rating systems, LTPP data analyses results, and application of the analyses to datasets from three State transportation departments.

This study tests the FHWA Highway Performance Monitoring System (HPMS) to determine if it is unbiased in its representation of the condition of IHS pavement. The researchers' other goals include collecting a statistically significant sample of the entire Interstate Highway System to make their determination and suggesting improvements to the HPMS data and reporting standards.

This project produced a guidebook, published by AASHTO, for developing and sustaining an enterprise risk management. The guidebook is available from AASHTO at https://bookstore.transportation.org/item_details.aspx?ID=2706.
