This book applies to a technical methodology used to manage assets and analyze risks to Russia's railway system.

The objective of this synthesis is to document DOT collaboration with MPOs relative to target setting, investment decisions, and performance monitoring of pavement and bridge assets for performance-based planning and programming. The synthesis will focus on DOT practices to initiate and facilitate collaboration with MPOs.

This updated version to the Highway Safety Manual User Guide aids safety analysts as they navigate and apply the Highway Safety Manual.

This resource provides an overview of asset management, data requirements, leading asset management practices in utilities, and a guide to asset management definitions. Several manuals are also available: M28 Rehabilitation of Water Mains; M32 Computer Modeling of Water Distribution Systems; and M77 Condition Assessment of Water Mains.

North Carolina has published their 2022 TAMP update. The North Carolina Department of Transportation (NCDOT, The Department) has long embraced data driven asset management practices. These practices were first compiled into a single asset management document in 2014. The TAMP is a strategic framework for considering the full life cycle cost and performance of transportation infrastructure. Long-term cost is minimized, and overall life and system-wide performance is maximized. The TAMP documents considerations for preserving the entire network of bridge and pavement assets.

As the importance of an integrated transportation system continues to evolve and grow, U.S. transportation agencies are identifying traffic signals as critical elements in asset management and long-range planning. Current research continues to suggest that transportation agencies can benefit from including traffic signals in their asset management planning and integrating asset management practices for traffic signal assets. This primer provides information for applying Transportation Asset Management (TAM) principles to traffic signals in accordance with the Transportation Asset Management Plan (TAMP) requirements.

As the importance of an integrated transportation system continues to evolve and grow, U.S. transportation agencies are identifying Intelligent Transportation Systems (ITS) assets as critical elements in asset management and long-range planning. Current research continues to suggest that transportation agencies can benefit from including ITS assets in their asset management planning and integrating asset management practices for ITS assets. This primer provides information for applying Transportation Asset Management (TAM) principles to ITS assets in accordance with the Transportation Asset Management Plan (TAMP) requirements.

This NCHRP report presents an assessment of the current and emerging forces shaping transportation planning practice and the transportation planning workforce. The objectives of this research were to (1) identify the knowledge, skills, abilities, education, and experience (KSAEEs) required for plan making and talent profiles for state, regional, and local transportation planners that are aligned with existing and emerging agency needs; and (2) provide guidance on how agencies can attract, develop, manage, and retain planning talent.

This research report supports the AASHTO Highway Safety Manual by establishing the methods for ensuring reliable results in crash prediction models.

Using a multi-asset approach emphasizing pavements and bridges, the tools and technologies presented in this study support strategic planning of maintenance, repair, and rehabilitation and project prioritization.
