"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"
Triodyne Safety Brief
v. 3 #3 (July 1985)

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"
Triodyne Safety Brief
v. 4 #3 (November 1986)

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"
Triodyne Safety Brief
v. 1 #3 (October 1992)

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"
Triodyne Safety Brief
v. 8 #4 (July 1993)

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"
SAE 95-0315
. Warrendale, PA, Society of Automotive Engineers, 1995

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"
Triodyne Safety Bulletin v. 1 #4 (August 1995)

Kenneth L. d'Entremont

A summarized version of the paper "Effects of Light-Vehicles Design Parameters..." described above.


"Who Ran the Red Light?"
Triodyne Safety Bulletin v. 3 # 3 (April 1996)

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?"
Triodyne Safety Bulletin v. 4 # 4 (September 1996)

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?
