Modular road barrier

A modular road barrier system, comprising:

• one or more road barrier modules, each module comprising:
• a first longitudinal beam comprising a first hollow portion along its length;
• a second longitudinal beam disposed below the first longitudinal beam, the second longitudinal beam comprising a second hollow portion along its length;
• a first upright connected to a first end of the first longitudinal beam and a first end of the second longitudinal beam;
• a second upright connected to a second end of the first longitudinal beam and a second end of the second longitudinal beam, the second longitudinal beam of each module has a width that is greater than any of the first upright and second upright;
• a connection system disposed on the first upright and the second upright, the connection system constructed and arranged to provide for mechanical connections to adjacent road barrier modules;
• protective elements spanning the length of the first longitudinal beam and second longitudinal beam and connected to the first upright and second upright,
• one or more lighting devices operatively connected to the module;
• one or more electrical devices positioned to measure one or more parameters around the module;
• a photovoltaic panel disposed on a top surface of the module operatively coupled to the one or more lighting devices or the one or more electrical devices;
• and
• a control unit constructed and arranged to operate the one or more lighting devices and the one or more electrical devices.
