Book Description
Across the nation, there are opportunities to improve coordination among transportation modal agencies, including aviation, transit, ports, highway, rail, pedestrian, and bicycle modes. Virginia's statewide multimodal transportation planning effort VTrans2025 addresses multimodal coordination of transportation investments in the state. Virginia's Secretary of Transportation submitted a final report of the VTrans2025 effort to the Virginia General Assembly in November 2004. The purpose of this study was to demonstrate an analytical methodology that could aid efforts such as this to coordinate and prioritize multimodal investments. The methodology developed can help decision makers to identify and prioritize proposed multimodal investment networks (MINs). These are large-scale coordinated investments in transportation projects across modes. The body of this report describes relevant literature and provides an overview of the developed methodology: (1) prioritization of the MINs, and (2) statistical comparison of modal plans. The analytical methodology developed will be of interest to multimodal transportation planning efforts across the nation, particularly where there is a need for systematic evidence-based approaches to coordinating the efforts of modal transportation agencies. Most data in the report are presented solely for purposes of demonstrating the methodology. The methodology developed in this project fosters improved coordination in planning and programming transportation investments across modal agencies. The potential benefits of the methodology include identification of lower-cost investment alternatives when considering multiple modes relative to considering only single modes to meet a particular travel demand; selection and programming of multimodal solutions that have the highest performance relative to the available or required levels of investment; and increased transparency and accountability of the multimodal agencies for the uses of funding that can be allocated across multiple transportation modes. The costs of implementing the methodology developed in this study are minimal and include one-time training of staff of the modal agencies in the use of the identification and priority-setting methodology and software demonstrated in the current study; and regular interaction and dialogue among the staff of the modal agencies that are involved in the identification and prioritization of investments across modes

Book Description
"These proceedings contain a summary of the Transportation Research Board conference on U.S. and international approaches to performance measurement for transportation systems that was conducted on September 9-12, 2007, at the Arnold and Mabel Beckman Center of the National Academies in Irvine, California. The theme for this third in a series of international conferences, Better Decisions and Better Communication, was selected to highlight opportunities for and experiences in using performance measurement as a strategic tool to better communicate goals and objectives and results to a wide range of stakeholder groups. Presentations highlighted cases in which performance measures have proved useful in guiding resource allocation decisions, improving day-to-day operations, establishing and demonstrating agency competency and accountability and, in some instances, making the case for more resources. The conference consisted of five plenary sessions, each followed by a series of corresponding, concurrent breakout sessions. The topics of the five plenary sessions were Performance Measures as an Organizational Management Tool to Establish Accountability, Communicating Performance Results Effectively to Your Customers, Data and Tools, Hot Topics (addressing the use of performance measures to gauge the effectiveness of tolling and congestion pricing and other innovative transportation strategies to address sustainability and safety issues), and Performance-Based Contracting and Measuring Project Delivery. Three resource papers were developed for the conference. The conference attracted 180 participants from Canada, Denmark, Germany, Italy, Japan, Mexico, Sweden, the United Kingdom, and the United States and featured 70 transportation specialists offering real-world expertise, from the application of performance metrics to case studies drawn from six countries. This range of experiences provided attendees with a comprehensive overview of the performance measurement techniques and approaches being applied to transportation systems in the United States and abroad."--Pub. desc.

Book Description
Within the structure of state government, some amount of transportation planning is usually performed within separate modal administrations, which may include aviation, bus, highway, ports, and rail, as well as separate toll agencies. Some states coordinate these planning efforts through a single office responsible for statewide multimodal planning; other states work to achieve such coordination without a centralized unit (described herein as the decentralized approach). To determine if there is value to centralizing statewide multimodal planning efforts within a single office, representatives from 50 states were surveyed regarding the utility of centralized versus decentralized multimodal statewide planning. Responses, in the form of written questionnaires and/or telephone interviews, were obtained from 41 states. Advantages of centralization included consistency of modal plans, better modal coordination (including detection of modal conflicts earlier in the process), an ability to examine the entire transportation system holistically, collective attention brought to smaller modes that otherwise might be overlooked, economies of scale for service delivery and employee development, and a greater likelihood that long-range planning will be performed instead of being eliminated by more immediate tasks (which might occur if such planning were located in an operational division). Advantages of decentralization included greater ease of obtaining modal support for the long-range plan since the planners and implementers are in the same functional unit, greater ease of tapping modal-specific expertise, an ability to focus on the most critical mode if one such mode is predominant, and organizational alignment with mode-specific state and federal funding requirements. Equally important were respondents' explanations of how the question of a centralized versus a decentralized approach may be overshadowed by external factors. These included constraints on how various transportation funds may be spent; the fact that having persons in the same office does not guarantee multimodal coordination; the recommendation that some efforts should be centralized and some should be decentralized; the increasing importance of MPOs, districts, and public involvement in planning efforts; and the suggestion that even after a solid analysis of alternatives, there may be cases where the recommendation is the same as what it would have been under traditional planning. In some instances, the use of performance measures may change the recommended approach. Finally, a subset of the free responses indicated that centralized multimodal planning can be beneficial but only if four constraints are met: modal staff work collaboratively, the centralized unit has funding or other authority, necessary modal-specific planning is not eliminated, and there is a clear linkage between the centralized unit and the agencies that perform modal-specific planning such that the latter can implement the recommendations of the former.

Book Description
The Office of Virginia's Secretary of Transportation identified 21 transportation policies and 42 performance criteria in Virginia's long-range multimodal transportation plan, VTrans2025. A subsequent planning effort, VTrans2035, provided direction for the effort described in this report. Although there has been considerable discussion of the potential impact of the VTrans policies on the Commonwealth as a whole, there has been little effort to characterize the regional and local impact of the policies. Further, the sensitivity of the policies to a variety of assumptions about the future needs to be better understood at statewide, regional, and local levels. This research effort developed and tested a methodology for scenario-based assessments of the impacts of the VTrans polices for several regions of the Commonwealth of Virginia. The methodology is implemented in an MS Excel workbook that is available for download at www.virginia.edu/crmes/multimodal2. This report describes a typical application of the methodology for a locality or regional planning organization, e.g., a Metropolitan Planning Organization (MPO) or Planning District Commission (PDC), to assess the impact of statewide multimodal policies across several of its long-range planning scenarios. The report includes a review of scenario-based planning, documentation of future scenarios, preliminary results of a survey of MPOs in Virginia for their best practices in scenario-based planning, an application of the methodology to the Roanoke region of Virginia, and recommendations. A major recommendation is that the methodology be used in VTrans2035 to catalyze and benchmark Virginia MPOs and localities in their respective efforts involving scenario-based transportation planning. The effort provides a cost-effective analysis tool that enables VTrans and MPOs and PDCs to identify and collaborate on the regional impacts of statewide transportation planning. The tool can further be cost-effective for individual MPOs and localities to engage in scenario-based long-range planning as encouraged by the Federal Highway Administration, particularly to guide the assumptions that are input to regional travel demand models. Appendix A provides the survey and study of scenario-based planning best practices. Appendix B documents the design of the Microsoft Excel workbook developed in this effort. Appendix C provides the lists of statewide policies, scenarios, and performance criteria used in the deployment of the workbook. Appendix D describes a related input/output analysis of economic growth based on transportation investments that was requested by the Office of Intermodal Planning and Investment. The developed methodology is being adapted for long-range scenario-based analysis of the Afghanistan Sustainable Infrastructure Plan, with research support from the U.S. Army Corps of Engineers.

Book Description
With the challenges attributable to increasing freight traffic and roadway congestion it is necessary to investigate opportunities for better management of goods movements. Rail-truck intermodal freight transportation can be considered as one such solution for reducing long-haul truck traffic on highways. For the rail-truck intermodal freight transportation to act as an effective transportation alternative, it is necessary to evaluate its impacts on the transportation system. A framework for evaluation of rail-truck intermodal terminal projects with qualitative and quantitative measures has been established using public goals and private stakeholder perspective. With the use of a case study, some of these measures have been evaluated. Recommendations have also made on data collection procedures for making a full scale evaluation. The case study selected for the Project is the proposed freight intermodal terminal at Petersburg, Virginia, conceived by the Norfolk Southern Corporation. This analysis formed a bridge between a region and a corridor based analysis. The key findings of the study are as follows: (a) Evaluation of an intermodal terminal project requires a systematic multi-regional modeling approach; (b) The impacts of an intermodal terminal are region and trade corridor specific; and (c) In cases where estimated intermodal rail drayage forms a small share of the overall truck traffic, the introduction of an intermodal terminal does not have substantial impacts on accessibility, mobility or safety. The study successfully developed models for estimation of impacts, including a two-stage accessibility model for drayage, a truck-rail mode choice model, truck involved crash models, and secondary local freight traffic impact model, mainly using data from the Commonwealth of Virginia.
