This publication contains two reports on highway finance. The first report, "The Evolution of the Highway-User Charge Principle," examines the financing concept that, for the most part, pays for building our highways, their maintenance and other related highway costs. It examines the history of road and highway financing in the U.S. and the develop

A latest model of field pile analyzer has been acquired for the proposed demonstration project on "Design and Construction of Driven Pile Foundations." The equipment will be used for demonstrations and technical assistance on construction projects. A request for demonstration and field monitoring of pile driving was received from the Idaho Transpor

Five channelizing devices were evaluated for safety via full scale crash tests at 60 mph using a minicompact sedan, a Volkswagen Rabbit. The five channelizing devices tested were the Plastibarrel 400-PB, the Channelizer, 55 gallon drums, the Wyoming WC-4 Barricade and the Virginia Simulated Barrel Panel. All impacts were survivable by the vehicle o

This research was conducted to determine (1) the extent of the accident problem associated with narrow bridge sites, (2) the relationships between frequency and severity of accidents to the design, geometry, and condition of the bridges and their approaches, and (3) characteristics of accidents at bridge sites. Environmental and accident data at br

This report describes the methods by which mid-size Metropolitan Planning Organizations (MPOs), between 200,000 and 750,000 in population are incorporating energy conservation concerns into their urban transportation planning process. Nine MPOs were selected for case study analysis. General conclusions were extrapolated from these case studies.
The Highway Safety Acts of 1973 and 1976 and the Surface Transportation Act of 1978 provide funding authorizations for individual states to improve safety at public rail-highway crossings. Safety improvements frequently consist of the installation of active motorist warning devices such as flashing lights or flashing lights with gates. To assist st
