This 2016 synthesis report presents a comprehensive scan of current methods and approaches to life-cycle cost analysis (LCCA) within highway agencies. The report features a literature review and individual case studies. It also includes the results of an agency survey.

Many state departments of transportation (DOTs) use a maintenance management system (MMS) to manage roadway maintenance activities. At some agencies, the MMS is part of a department-wide asset
management system. The MMS may also be linked with other agency systems and databases, such as human resources or financial systems.

To learn more about state DOTs’ use of maintenance management systems, in July 2016 the No Boundaries pooled fund project sent an online survey to maintenance representatives in all 50 states. The survey questions were designed to build on previous surveys conducted by Iowa DOT (February 2016) and Montana DOT (March 2014, through the AASHTO Research Advisory Committee).

The objective of this research is to develop proposed AASHTO guidelines for a data-driven risk assessment at the bridge and structure level. The guidelines considered risks from natural and man-made hazards and aimed to be useful in a bridge management system.

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.
