• Identifying Optimal Mix of Highway Asset Maintenance Activities Based on Performance Targets or Budget Constraints
  Abstract: The majority of maintenance optimization literature is focused on pavement maintenance related to pavement management systems. The question of how properly to optimize the full range of typical highway maintenance activities based on measurement and prediction of performance is not well covered, and practitioners are only now getting started in this area using software tools to aid in planning non-pavement related maintenance. While much of the optimization work to date focuses on predicting deterioration explicitly over time, this paper presents a method of maintenance optimization, here called maintenance analysis, that assumes a steady state is reached with regard to maintenance activities. The use of this maintenance analysis method allows maintenance managers to use levels of service (LOS) and utility functions to define maintenance indices. It thereby allows the manager to identify and plan the optimal mix of maintenance activities to maximize performance with respect to maintenance performance indices or minimize cost based on user defined budget constraints or LOS targets respectively. The paper presents a simple numerical example to illustrate the method.

• Measuring Perceived Service Quality in Highway Maintenance
  Abstract: The concept of involving the public in the development of transportation solutions was built into the Federal-Aid Highway Act of 1956, the legislation that authorized the construction of the Interstate Highway System. Better plans, transparent process, and public support are some of the benefits that road managers can obtain by educating and involving the general public. During the last two decades the volume of research performed related to the topic of customer-driven highway maintenance suggests an increasing level of interest in the field. Most research concentrates on gathering information from road users to assess the performance level of highways. However, public opinion can also be collected for measuring the quality of the service delivered by maintenance units. Assessing product and service delivery performance is important for determining the overall performance of highway maintenance programs. The present study examines the relationship between road users' overall perceptions of the quality of highway maintenance services and the variables that define the highway maintenance service quality domain. The results of the study indicate that two service dimensions, Safety and Reliability, explain about half of the variance in overall perceptions of highway maintenance service quality. The procedures developed for the study provide an initial step for further improvement of the highway maintenance perceived service quality measurement.

• Risk-Based Corridor Asset Management: Applying Multiattribute Utility Theory to Manage Multiple Assets
  Abstract: Simultaneous consideration of various types of assets and investment objectives for the purpose of allocating resources more efficiently can improve the system-wide performance of the transportation system. Currently, various studies have been conducted on the development of management systems such as pavements, signs, mobility, safety, or preservation. However, studies that specifically investigate the synergistic effects of these systems on transportation system performance are not as many. This paper develops a multi-attribute utility model that identifies high-risk corridors within a transportation system for prioritization, based on multiple objectives and various assets. Three objectives are used in evaluating the performance of the system: minimizing the number of incidents, maximizing mobility, and improving preservation of assets. The methodology is generally applicable to system-level management of transportation systems. The model is applied to a selected corridor in the state of Georgia. The results illustrate that the developed model can aid transportation agencies in identifying high-risk corridors that degrade the performance of their transportation system. This model can be used in identifying high-risk corridors during program development.

• Cross-Asset Resource Allocation Framework for Achieving Performance Sustainability
  Abstract: The resource allocation across multiple assets in transportation systems has gained significant attention over the past few years. In this context the present paper proposes a framework to help decision makers estimate the optimal resource allocation across multiple assets considering functional, structural, and environmental performance indicators. The CO2-equivalent emissions are considered in the calculations along with condition measures to evaluate the optimal budget allotment scenario that will lead to structural and functional integrity as well as environmental sustainability. The application of the framework is demonstrated in a case study with pavement and bridge assets. The results show that the framework can be used as a supporting tool for decision makers and transportation agencies to estimate the optimal budget to invest on each asset. The paper also evaluates the impact of different parameters on the resource allocation policy with a sensitivity analysis. The findings show that the initial condition of assets, and the priority (weights) assigned to each indicator (functional, structural, and environmental) can change the optimal resource allocation scenarios. It was also found that the relative size of the assets has notable impact on the optimal budget share. Finally, the paper discusses the need for agencies to consider their own data inputs, and provides recommendations for future research.
