Speed Tables

Speed tables are flat-topped speed humps and are generally long enough for the entire wheelbase of a passenger car to rest on top. The design of speed tables allows for more gradual slowing of vehicle speed than humps. This makes speed tables the ideal solution for roads with typical residential speed limits.

General description:
Speed Humps and Speed Tables of various dimensions are constructed using interlocking modules (US patent pending 12633-23USPR). The standard foot print dimensions of each module are 18” by 42”. The weight of the various modules is between 50 and 100 lbs. Each unit is bolted to a paved road surface using six lag bolts 3/8” dia. through a plastic shield installed in the road surface. The Traffic Logix proprietary two directional tongue and grove interlocking system provides additional connection between the modules and increases stability of the speed hump or speed table.
