EVALUATION OF WHEEL BLOCKING FOR VEHICLES PARKED ON SLOPES

A safety measure commonly employed to prevent vehicles parked on sloping roadways from rolling accidentally is to block 1 or more wheels or by using an available curb as a blocking device. An analytical study of the equilibrium of a vehicle in this state permits assessment of the relative advantages and disadvantages of blocking lower or upper wheels, reveals that vehicle weight and block shape are unimportant, and leads to a description of various failure modes. The relationship between curb height and maximum safe roadway slope is explored, and it is shown that trucks present a greater safety hazard than do passenger automobiles. /Author/
