One-way speed bump

Abstract

A one-way speed bump for controlling both direction and speed of traffic is described. The speed bump has a shallow front face and a steep rear face. Vehicles approaching the front face of the speed bump are allowed to pass over the speed bump at a controlled rate of speed. Vehicles attempting to pass from the wrong direction will engage the steep rear face of the speed bump. This will cause the vehicle to be jolted and possibly damaged. Indicia may be provided on the steep rear face to warn drivers that they are traveling in the wrong direction.

1 . A speed bump comprising:
 a bottom surface;   a front face comprising a relatively shallow angle measured from the bottom surface structured and arranged to allow vehicular traffic approaching the front face to pass over the speed bump; and   a rear face comprising a relatively steep angle measured from the bottom surface structured and arranged to deter vehicular traffic approaching the rear face from passing over the speed bump.   
   
   
       2 . The speed bump according to  claim 1 , further comprising a top portion between the front face and the rear face. 
   
   
       3 . The speed bump according to  claim 1 , further comprising indicia on the rear face. 
   
   
       4 . The speed bump according to  claim 3 , wherein the rear face comprises a recess and wherein the indicia are located within the recess. 
   
   
       5 . The speed bump according to  claim 1 , wherein the shallow angle between the bottom surface and the front face is between about 10 and about 35 degrees. 
   
   
       6 . The speed bump according to  claim 1 , wherein the shallow angle between the bottom surface and the front face is about 15 degrees. 
   
   
       7 . The speed bump according to  claim 1 , wherein the steep angle between the bottom surface and the rear face is between about 35 and about 100 degrees. 
   
   
       8 . The speed bump according to  claim 1 , wherein the steep angle between the bottom surface and the rear face is about 60 degrees. 
   
   
       9 . The speed bump according to  claim 1 , further comprising anchor holes passing through the speed bump. 
   
   
       10 . The speed bump according to  claim 9 , wherein the anchor holes extend through the front face and the bottom surface in a direction substantially perpendicular to the bottom surface. 
   
   
       11 . The speed bump according to  claim 10 , further comprising bolts passing through the anchor holes, wherein the bolts are connected to anchors secured to a road. 
   
   
       11 . The speed bump according to  claim 1  comprising a single, solid piece of material. 
   
   
       12 . The speed bump according to  claim 1 , wherein the speed bump has an overall height of about 1½ to about 6 inches. 
   
   
       13 . The speed bump according to  claim 1 , wherein the front face is substantially flat and the rear face is substantially flat. 
   
   
       14 . The speed bump according to  claim 1 , wherein the front face is curved and the rear face is curved.
