Wireless sensing and communication system for traffic lanes
First Claim
1. A driving condition monitoring system for a vehicle on a roadway, comprising:
- sensors located on or in a vicinity of the roadway, said sensors being configured to obtain and transmit information about the roadway, travel conditions relating to the roadway and external objects on or in the vicinity of the roadway using a wireless radio frequency mechanism;
at least one interrogator arranged on the vehicle that causes said sensors to transmit the obtained information and then receives the information obtained and transmitted by said sensors; and
a communications device arranged on the vehicle and coupled to said at least one interrogator, said communications device being configured to transmit the information received by said at least one interrogator from said sensors to a remote location separate and apart from the vehicle and the roadway using a bi-directional communications channel between the remote location and the vehicle,wherein the information received by said at least one interrogator from said sensors is provided to an operator of the vehicle in addition to being transmitted to the remote location by said communications device; and
wherein said communications device is configured to receive from the remote location, using the bi-directional communications channel between the remote location and the vehicle, information about the roadway, travel conditions relating to the roadway and external objects on or in the vicinity of the roadway obtained by the remote location from at least one other vehicle.

Abstract
Wireless sensing and communication system including sensors located on the vehicle, in the roadway or in the vicinity of the vehicle or roadway and which provide information which is transmitted to one or more interrogators in the vehicle by a wireless radio frequency mechanism. Power to operate a particular sensor is supplied by the interrogator or the sensor is independently connected to either a battery, generator, vehicle power source or some source of power external to the vehicle. The sensors can provide information about the vehicle and its interior or exterior environment, about individual components, systems, vehicle occupants, subsystems, or about the roadway, ambient atmosphere, travel conditions and external objects. The sensors arranged on the roadway or ancillary structures would include pressure sensors, temperature sensors, moisture content or humidity sensors, and friction sensors.
