Abstract: A modular system for separating traffic into discrete zones includes a plurality of rail segments pivotally secured to rail mounts. The mounts are configured for rapid and straightforward coupling of rail segments thereto. Moreover, the mounts may be quickly installed and de-installed from a road surface. The overall system therefore provides a physical barrier system that is easily installed and easily modifiable into desired arrangements. Its modular construction of any number of a plurality of distinct rail segments further facilitates customized channelizing design.

Abstract: A paving block is provided that includes a top surface, a bottom surface and a side surface extending between the top surface and the bottom surface. The side surface includes a recess extending from the top surface to the bottom surface, wherein the recess has a top opening in the top surface and a bottom opening in the bottom surface, wherein the bottom opening is larger in area than the top opening. The side surface also has at least a portion that extends inwardly into the paving block. In some cases, the side surface comprises an upper side surface section and a lower side surface section, wherein the lower side surface section extends inwardly into the paving block.

Abstract: A paving block system is provided that includes a plurality of paving blocks arranged together to form a surface. Each paving block includes a recess located on a side surface and the paving blocks are arranged so that each recess abuts another recess so as to form drainage holes in the surface. The drainage holes have a top opening and a bottom opening and the bottom opening is larger in area than the top opening.
