Abstract: The present inventions provide a system and method for providing a warning using at least one wireless communication link between an approaching object and the location where a warning is to be given based in part on the location of the object and its proximity to the warning location. One aspect of the inventions includes receiving a communication from an object, for example a vehicle, which includes location information, at an alert node, wirelessly communicating alert information to a warning node, and causing a warning device to generate a warning. Preferably the alert node communicates with a plurality of vehicles and a plurality of warning nodes and determines to which of the plurality of warning nodes to communicate alert information based in part on the location information received from at least one of the vehicles and the location of the warning device.

Abstract: A modular in-road lighting system is easily installed in the road and is convenient for repair, replacement and maintenance. The lighting system includes at least one modular light, at least one modular cable and a control unit. The top surface of the modular light is flush with a road surface so as to avoid abrasion by passing items. The modular light includes an illumination source and a control circuitry. The illumination source and the control circuitry are configured to emit light in selected direction(s).

Abstract: A traffic informational system provides information to traffic moving along a road and may include a plurality of traffic information devices mountable to the road, each having an integral power producing source, at least a first set of illumination sources, and a wireless communications subsystem. The traffic informational system may further include at least a first external control device comprising at least one antenna and a transmitter communication wirelessly with the traffic information devices and/or with one another. The traffic information device may communicate with one another, and may include sensor for sensing ambient conditions. The system employs various approaches to reducing power consumption and improving communications, and is suitable for a wide range of applications, including use in remote environments.
