Fitting Into the Process: Institutional Issues Affecting Development and Deployment of Automated Highway Systems97265608/06/1997
A research effort in response to institutional issues identified by the National Automated Highway System Consortium -- particularly the steps necessary to integrate Automated Highway Systems (AHS) into the transportation planning and decision-making process -- revealed not only the concerns to be addressed and barriers to be overcome in developing and deploying AHS, but also issues and barriers transportation officials at every level already confront in the current, and rapidly changing, legislative, funding and technological environment. The findings also suggest possible institutional blocks toward intelligent transportation systems in general and AHS in particular.

Validation of the Reduction of Rear-End Collisions by a High-Mounted Auxiliary Stoplamp81018902/01/1981
This study was a field validation of the effectiveness of an auxiliary high-mounted stoplamp in reducing rear-end collisions. A previous study (DOT-HS-803-467), using taxi-cabs, found a 54 percent reduction in relevant rear-end impacts to vehicles equipped with the auxiliary stoplamp. The present study used 5,400 telephone company passenger vehicles, half test, half control, which accumulated 55 million miles during a 12-month continuous data collection period. The results showed a statistically significant 53 percent reduction in relevant rear-end impact rate in the test group as compared to the control group. The findings were thus consistent with the previous study on taxicabs.

Development and Evaluation of Aluminum Body Sheet Metal Panels77030302/01/1977
A developmental approach was adopted to establish aluminum as a viable body sheet material for vehicle weight reduction. Initially, both the material advantages of aluminum, as well as certain limiting factors for automotive processing were recognized. A major plant trial was conducted and methods of resolving both functional and processing issues evolved. The in-plant tryout and subsequent field evaluation of hood panels produced useful information on forming, welding, metal finishing and painting as well as appearance and functional elements pertinent to product field performance. Panels from this trial were evaluated at intervals during two years of exposure to demanding field conditions. During this same period laboratory efforts resolved remaining, less-critical issues.
