Abstract
A portable speed bump, for use in limiting the speed of vehicles that are traveling on a road, is formed from a plurality of elongated speed bump modules. Each module has a cross-section that has at the most, a low slope from the outer edges toward the mid-line and a substantially increased slope proximate the module mid-line, a length of at least two feet, a width of at least one foot, and a height of at least one inch. Each module has an upper surface which has a concave slope region from outer edge to middle section and a convex middle section. Anti-skid elements can extend from the planar lower surface, whereby lateral movement of said speed bump is resisted. The elements can be a plurality of substantially parallel, outwardly angled anti-skid fingers.
