    Funding Tomorrows' Transportation Systems
    (Georgia Institute of Technology, 2008-04-11) Walton, C. Michael
    The US is facing a national transportation crisis in system performance, funding and policy. The highway infrastructure alone needs an investment of $3.1 Trillion over the next 30 years. The next national transportation authorization is considered the most critical since 1956. This bill will chart the path for transportation in the 21st century. What are the options that may be the pillars for the authorization? Is there a new transportation vision for the nation?

    Agent-Based Models as an Insight into Managing Pavement Assets
    (Georgia Institute of Technology, 2008-02-22) McNeil, Sue
    Asset management is a systematic process to support strategic decision making for physical assets. Recognition of budget constraints, development and use of deterioration models, development of strategies and policies, and project selection are important elements of the process. More sophisticated asset management decision support systems also recognize the uncertainty inherent in the process and the challenges in allocating resources in a spatially and socially equitable manner over the extended periods of time that the assets are expected to provide service. However, little attention has been paid to capturing the complex interactions among decision makers. While asset management has been emerging as a discipline, agent-based modeling, a tool for exploring complex systems, has demonstrated the potential to model important interactions and heuristics that reflect the actual management process. By representing a network of pavement segments as an agent-based model, we can examine the effects of agencies, politicians, user actions, deterioration, random failures and various policies on the performance of the system. The presentation defines potential agents – the pavement segments, users, politicians, and engineers – and their interactions, and explains why such agent behaviors are not captured in typical pavement management systems and life cycle cost analyses. Two prototypes agent based systems are presented and demonstrate the potential value of life cycle cost analysis and the importance of planning for catastrophic failure.

    An Approach to Georgia Information Intensive Transit (GIIT)
    (Georgia Institute of Technology, 2007-09-25) Dickerson, Stephen L.
    Professor Dickerson described a visionary idea that could change the way we think about public transportation in the future. In his concept one would use cell phones to request a carpool, to track their location and even as a key to enter the shared vehicles. These vehicles may be driven by the users themselves and would be parked in designated lots scattered around the urban areas. After requesting a carpool, one would simply drive to the closest designated lot to take the appropriate carpool and drive to one’s destination along with other users of the system. The cell phone is a key ingredient to this scheme. It tells you exactly when and where to meet your ride, it assigns to you a rental car near your office or home when needed and allows you to access the auto and pay your fares, MARTA, car rentals and van and car pools, automatically.
