Book Description
Resource allocation mechanisms have become a major issue for transportation agencies in the United States and around the world. For this reason, transportation agencies are exploring alternatives to modify traditional allocation mechanism due to budgetary challenges generated by the decrease in funding and the increasing cost of preserving and operating transportation systems. Transportation asset management (TAM) practices enable agencies to change the operation and management of transportation infrastructure from the traditional concept of “public-owned” systems to more business-oriented processes. One of the main concerns with the TAM framework and its implementation is the absence of an organized process for cross-asset resource allocations. Additionally, most of the alternative methods for funding allocations focus on maximizing infrastructure performance under budget constraints, but ignore the consideration of equity or fairness. The objective of this study is to develop an innovative methodological framework for cross-asset resource allocations, yielding a data-oriented approach to enhancing infrastructure management. The allocation module is comprised of three resource allocation mechanisms following a top-down approach: a fair division approach based on asset performance, a performance-based multi-objective optimization, and an asset value-based multi-objective optimization. In the first mechanism, the fair division method is used to allocate resources in such a way that all parties involved believe they are receiving a fair share of the available resource based on established utility functions. Then, Collective Utility Functions (CUFs) are employed to perform the resource allocation, which results in total utility and total envy values. These values are used to conduct trade-off analyses of the different allocations based on the CUFs. Under the second procedure, a multi-objective optimization formulation is employed to integrate efficiency and equity, where equity is taken into consideration by using utility and envy concepts, while efficiency is incorporated by maximizing performance. In the third mechanism, an innovative asset value methodology is integrated into the cross-asset resource allocation process, serving as a common comparative measure between assets. To demonstrate the applicability of the proposed methodological framework, a case study was conducted using two asset groups, pavements and bridges, from the roadway network of the Austin District located in Texas. Results from the case study shows that the proposed methodological framework has great potential as a tool to support highway agencies in performing cross-asset resource allocations at the network level.

Book Description
This report extends and implements the results of NCHRP Report 806: Cross-asset Resource Alloocation and the Impact on Sustem Performance. Case studies were used to illustrate key issues in implementing a cross-asset resource allocation approach, and the lessons learned were then used to imporve the guidance and tools developed in NCHRP Report 806.

Book Description
"Roadway infrastructure within the United States includes features such as roads, bridges, signs, pavement markings, traffic signals, support commerce and mobility, and is, in essence, a shared financial public resource worthy of being managed at the highest level of efficiency. State departments of transportation (DOTs), local transportation authorities, and federal agencies responsible for the fiscal management of the transportation system have shown a growing interest in advancing the state of practice in managing these critical assets. In addition, the recent congressional passage of Moving Ahead for Progress in the 21st Century Act (MAP-21 Act) has established an outcome-driven, performance-tracking approach that will hold states and metropolitan planning organizations accountable for improving the conditions and performance of their transportation assets. It will therefore increase agency attentiveness to these vital issues. Transportation Asset Management (AM) is a strategic and systematic process of operating, maintaining, upgrading, and expanding physical assets effectively throughout their life cycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based on quality information and well-defined objectives. Advancing AM capabilities and integrating these capabilities across an organization's business units requires self-assessment, alignment, goal setting, and support. This synthesis of transportation asset management practice among state highway agencies will be a timely resource for agencies to identify their current state of practice and determine where they will direct their AM efforts. This synthesis is based on two separate surveys, with additional input from practitioners. The initial survey requested that participants conduct a self-assessment to characterize their agency's AM practices....The self-assessment results reflect current and future (5-year) business practices and the agencies' institutional, organizational, financial, and IT environments. This survey yielded 18 DOT participant responses (see Appendix D). Based on the results of the initial survey, and input from the Topic Panel, a second survey was designed to capture the state of practice and forward looking expectations (for the next 3 to 5 years) among state DOTs. Forty-three agencies participated in this second survey."--p. 1.

Book Description
This report presents policy options for extending the life of road assets by mitigating deterioration caused by trucks. Beyond traditional engineering responses, it considers the role of trucks in road asset deterioration from a broader, demand-oriented perspective.

Book Description
The research described in this report assembles a set of tools based on experiences and best practices in a diverse set of states for linking strategic goals to resource allocation and implementation decisions using aspects of asset management. A survey of practices in each of the state DOT's that explores documents and synthesizes both strategic planning processes and asset management was conducted. With input from an expert advisory panel, five states were for detailed analysis. These are Florida, Maryland, Michigan, Montana and Pennsylvania. The model process that results does not represent any particular state, but incorporates elements from all five states. This model process can provide useful guidance to states interested in augmenting their existing process.

Book Description
World population growth and economic prosperity have given rise to ever-increasing demands on cities, transportation planning, and goods movement. This growth, coupled with a slower pace of transportation capacity expansion and deteriorated facility restoration, has led to rapid changes in the transportation planning and policy environment. These stresses are particularly acute for megacities where degradation of mobility and facility performance have reached alarming rates. Addressing these transportation challenges requires innovative solutions. Megacity Mobility grapples with these challenges by addressing transportation policy, planning, and facilities in a multimodal context. It discusses innovative short- and long-term solutions for meeting current and future mobility needs for the world’s most dynamic cities by addressing the influence of urban land use on mobility, 3D spiderweb transportation planning, travel demand management, multimodal transportation with flexible capacity, efficient capacity utilization driven by new technologies, innovative transportation funding and financing, and performance-based budget allocation using asset management principles. It discusses emerging issues, highlights potential challenges affecting proposed solutions, and provides policymakers, planners, and transportation professionals a road map to achieving sustainable mobility in the 21st century. Zongzhi Li is a professor and the director of the Sustainable Transportation and Infrastructure Research (STAIR) Center at Illinois Institute of Technology (IIT). Adrian T. Moore is vice president of policy at Reason Foundation in Washington, D.C., with focuses on privatization, transportation and urban growth, and more. Samuel R. Staley is the director of the DeVoe L. Moore Center in the College of Social Sciences and Public Policy at Florida State University.
