This report summarizes the research results in the Automated Check-in Activity Area. Situations in AHS where transition from manual to automated control takes place are analyzed. In particular, vehicle fitness testing to ensure safe and smooth automated operation has been emphasized. The check-in procedures presented here and an effective malfuncti

The objectives of this project were to define the problems older drivers and pedestrians have at intersections, and make recommendations for changes. A literature review, a detailed accident analysis, and eight focus groups were conducted to identify the specific kinds of traffic-control-related problems experienced by older drivers and pedestrians

This document presents aggregate statistics derived from the 1992 Interstate Motor Carrier Inspection Database. The database was compiled from the records of driver-vehicle inspections conducted during Calendar Year 1992 by State and Federal officials responsible for commercial motor vehicle safety. The database is maintained by the Office of Motor

This manual provides state-of-the-practice methods and techniques to assist the highway engineer in the planning, design, and construction monitoring of dynamic compaction to improve the load supporting capacity of weak foundation soils. Guidelines are presented for: completing a preliminary evaluation to determine if dynamic compaction is appropri

As the proportion of Americans 65 years of age and older continues to increase, motor vehicle accidents involving older drivers and pedestrians are becoming a significant traffic safety concern. Intersections appear to be particularly hazardous to both elderly drivers and pedestrians. In addition to a literature review and focus groups examining a

This report contains selected information on toll facilities in the United States. The information is based on a survey of facilities in operation, financed, or under construction as of January 1, 1995, and is presented in four tables. Table T-1 contains information such as the name, financing or operating authority, location and termini, feature c

This paper addresses the relationship of truck size and weight (TS&W) policy, vehicle handling and stability, and safety. Handling and stability are the primary mechanisms relating vehicle characteristics and safety. Vehicle characteristics may also affect safety by mechanisms other than handling and stability. For example, vehicle length may affec

In general, very little work has been done relating the impact of changing truck size and weight (TS&W) regulations to impacts on the environment. Some work was done by the American Trucking Associations in the late 1970s and early 1980s. Other work by the Society of Automotive Engineers, the Environmental Protection Agency and several European sou

The intention of this working paper is to provide researchers and policy analysts with as much information about estimating the effects of potential policy changes on usage of alternative truck configurations and on modal diversions as it is practical to assemble within a limited period of time. The first section of this paper contains an extended

The research on various truck size and weight considerations and energy conservation is limited. Following the energy crisis in the mid 1970s, there was significant interest and research on energy conservation. Most of the references cited in this working paper are from this period. With the stabilization of fuel supplies and the decline in fuel pr

This paper gives particular attention to the importance of enforcement actions as an integral part of Truck Size and Weight Regulations, and to the potential impacts of changes in TS&W regulations, on the costs and effectiveness of enforcement activities. A great deal of recent research has been conducted on the problems of overweight travel and en
