Abstract
Moped response, performance, and accident avoidance capabilities are assessed. Moped design features are reviewed. Four instrumented vehicles were evaluated. Full scale tests included: steady turn, lane change, free control stability, roadway disturbances, open and closed loop braking, acceleration/top speed, and hill climb. Two wheeler test procedures and measures are presented, along with subjective evaluations. Sensitivity to operating variables are quantified. Potential safety-related handling problems were identified. A typical moped was modified for increased speed performance, and upgraded brake and tire components.
