Smart modular street and sidewalk

A modular system for streets, said system comprising:

• a top module, said top module configured removable from said system;
• a bottom module of unitary construction and having a height of two feet to four feet, comprising a base portion and at least three vertical walls, said bottom module constructed and arranged to connect one to another with successive bottom modules, and an upper surface of said at least three vertical walls of said bottom module configured with a plurality of orifices to mate by direct clamping with a plurality of protuberances formed on an underside of said top module wherein when said top module and said bottom module are mated, a plurality of internal cavities are formed between said base portion of said bottom module and said underside of said top module, each one of said internal cavities between a pair of said at least three vertical walls;
• cables positioned within at least one of said internal cavities;
• at least one of a sewer or water pipe positioned within at least one of said internal cavities;
• a computing device;
• sensors operatively associated with said computing device, said sensors comprising at least visual sensors embedded on the surface of the street;
• and
• communications hardware configured to communicate information from said sensors to a second computing device positioned exterior to said modular system.
