This book provides an overview of the federal role in surface transportation and the goals and structures of federal programs. Since federal financing for the interstate system was established in 1956, the federal role in surface transportation has expanded to include broader goals, more programs, and a variety of program structures. The nation has reached a critical juncture with its current surface transportation policies and programs. Demand has outpaced the capacity of the system, resulting in increased congestion. In addition, without significant changes in funding levels or planned spending, the Highway Trust Fund -- the major source of federal highway and transit funding - is projected to incur significant deficits in the years ahead. Exacerbating concerns about the solvency of the Highway Trust Fund is the federal government's bleak fiscal condition and outlook. As a result, other federal revenue sources may not be available to help solve the nation's current transportation challenges. Given the scope of needed transformation, it may be necessary to shift policies and programs incrementally or on a pilot basis to gain practical lessons for a coherent, sustainable, and effective national program and financing structure to best serve the nation for the 21st century.

This report provides a historical perspective on contemporary federalism issues in surface transportation policy that are likely to be addressed by Congress during the 111th Congress, including possible devolution of programmatic responsibility to states and proposals to change state maintenance-of-effort requirements and state cost matching requirements.

The Intelligent Transportation System (ITS) Program is a cooperative effort by government, private industry, and academia to apply advanced technology to the task of resolving the problems of surface transportation. The objective is to improve travel efficiency and mobility, enhance safety, conserve energy, provide economic benefits, and protect the environment. The current demand for mobility has exceeded the available capacity of the roadway system. Because the highway system cannot be expanded, except in minor ways, the available capacity must be used more efficiently to handle the increased demand. ITS applies advanced information processing, communication, sensing, and computer control technologies to the problems of surface transportation. Considerable research and development efforts will be required to produce these new technologies and to convert technologies developed in the defense and space programs to solve surface transportation problems. ITS has been subdivided into six interlocking technology areas. This book addresses human factors concerns for four of these areas: * Advanced Traveler Information Systems are a variety of systems that provide real time, in-vehicle information to drivers regarding navigation and route guidance, motorist services, roadway signing, and hazard warnings. * Advanced Vehicle Control Systems refer to systems that aid drivers in controlling their vehicle particularly in emergency situations and ultimately taking over some or all of the driving tasks. * Commercial Vehicle Operations address the application of ITS technologies to the special needs of commercial roadway vehicles including automated vehicle identification, location, weigh-in-motion, clearance sensing, and record keeping. * Advanced Traffic Management Systems monitor, control and manage traffic on streets and highways to reduce congestion using vehicle route diversion, automated signal timing, changeable message signs, and priority control systems. Two technical areas are not specifically addressed in individual chapters, but many aspects of them are covered in associated chapters: * Advanced Rural Transportation Systems include systems that apply ITS technologies to the special needs of rural systems and include emergency notification and response, vehicle location, and traveler information. * Advanced Public Transportation Systems enhance the effectiveness, attractiveness and economics of public transportation and include fleet management, automated fare collection, and real-time information systems.
