A paper that describes new methodology for transportation investment decisions, with consideration to project interdependencies.

This document describes the process by which the use of levels of service can facilitate the estimation of asset deterioration and life expectancy.

A report on the effect of pavement roughness on user costs.

This report presents a culvert deterioration model, and various culvert asset management practices.

This report presents analysis of key variables affecting decisions of bus replacement age and total costs.

A paper that provides service life analysis, and proposes a maintenance program for pavement markings in Thailand.

A report on the assessment of sign retroreflectivity for the development of an asset management plan, using a new data collection plan.

This report focuses on the factors considered in the prioritization of pavement rehabilitation projects. The research team evaluated current practices for data collection and integration to gain an understanding of the potential needs for improvement in the decision-making process.

This document contains findings from a literature review and from a survey concerning New Zealand asset management practices. A strategy is proposed for the improvement of data collection and management, which in turn is expected to allow for further development of advanced bridge asset management.

This document describes the ways in which road deterioration (RD) models could be developed to assign various possibilities to a pavement's future (as opposed to offering one possibility), using a probabilistic approach. The report outlines the applications of a probabilistic approach at both the project and network levels.

This document provides an overview of a preventative approach to civil liability risk for road authorities. The report provides background information on claims against road agencies and recommends TAM practices for improved system performance and prevention of claims.

This study seeks to determine how state departments of transportation (DOTs) are using TAM and related techniques to address existing and anticipated future travel demand. Correspondingly, this study attempts to identify and document all cases in which state DOTs have incorporated travel demand measures within TAM and related analyses and decision-making processes.
