"On the Safety of Motorcycle Side Stands" Triodyne Safety Brief v. 2 #4 (September 1984) Dror Kopernik When a motorcycle is banked to the left with its kickstand in the down, or
park, position, the contact between the kickstand and the pavement can cause the
driver to loose control. This paper explores the design parameters affecting
kickstand retraction.
"Trailer Hitches and Tow Bars" William Switalski and Ralph L. Barnett A survey of trailer hitch requirements in the 50 states highlights problems
of uniformity, communications, suitability, and design specificity.
"Mandatory Seat-Belt Usage Laws: Exemptions to the
Rule" Gary M. Hutter and Cheryl A. Hansen By 1986 twenty-seven states had passed mandatory seat-belt usage laws, all of
which provided a variety of exemptions to mandatory usage. The categories and
distribution of these exemptions are examined.
"Zero Obstruction Repair Overpass" Ralph L. Barnett The Zero Obstruction Repair Overpass (Z.O.R.O.) is a new concept enabling
roadways to be repaired without interrupting normal traffic flow. Z.O.R.O. is a
movable prefabricated hill which cars drive over while construction proceeds
underneath. Its lightweight, reusable modular design incorporates techniques
developed for military bridge construction.
"Under the Influence of Alcohol" John P. Bederka Factors in intoxication are reviewed, and methods of determining intoxication
are discussed. A helpful guide for the expert witness/consultant involved in DUI
litigation.
"Effects of Light-Vehicle Design Parameters in
Tripped-Rollover Maneuvers: A Statistical Analysis Using an Experimentally
Validated Computer Model" Kenneth L. d'Entremont This research includes experimental tests of eight light-duty vehicles and
validation of complex computer models and simulations in soil and curb tripped
rollover situations. Analyses support the conclusion that tripping from soil is
qualitatively different from tripping over curbing.
"Light-Duty
Vehicles in Tripped-Rollover Situations" Kenneth L. d'Entremont A summarized version of the paper "Effects of Light-Vehicles Design
Parameters..." described above.
"Who Ran the Red Light?" Dror Kopernik and John Goebelbecker Reconstruction of vehicle accidents involves analyzing physical and
testimonial evidence. However, physical evidence that remains after a collision
in an intersection is independent of signal-light color and can never resolve
the question of who ran the red light. Furthermore, drivers often disagree and
witnesses may not have observed the lights in question. In these cases,
analyzing testimony that correlates the color of any signals in the intersection
with accident events may reveal the culprit.
"Is a Left Turn Right?" John Goebelbecker, Michael A. Dilich and Dror Kopernik A heavy truck is about to turn left onto a high-speed, multi-lane highway. An
approaching car in the distance appears far enough away for the truck driver to
pull out and start his turn. Seconds later, a collision occurs. What went wrong?
