Abstract

This article contains a computer program written by the author in the QBASIC programming language for readers of Accident Reconstruction Journal. This program was designed to be a stimulus for all to experiment with computer programming, and assist in the analysis of critical speed yaw calculations. This program may be used for critical speed analysis immediately and requires no modification. Critical speed yaw and critical curve speed are two important equations in determining speed problems in which a vehicle leaves the road on a curved surface. This program will produce speeds in metric (kph) and USA (mph) units of measure, and will automatically generate a table of speeds with increments of the radius variable at 10 feet/meters increments. To use the program, one needs an IBM/DOS or compatible computer with at least DOS 5.0, or Microsoft's QuickBasic.
