System and Method to Ensure Road Lane Safety and Track Issues During Inclement Weather

Disclosed is a method and system for alerting an operator of an automobile about lane markings on a roadway using RFID technology so as to assist the operator to safely travel within boundaries of the roadway. During harsh weather conditions, it may happen that the lane markings on roadways become invisible to the operator. For example, snow, ice, leaves etc. may inhibit the operator from viewing visible markings on the roadway. This may result in unsafe travel conditions for commuters.

The publication provides a lane tracking system for tracking the position of an automobile with respect to lane markings on a roadway. The lane tracking system includes passive RFID tags embedded along the boundaries of lanes. An RFID reader situated on the automobile periodically probes the RFID tags. Based on the response from the RFID tags, the lane tracking system determines the position of the automobile with respect to the lane markings. Subsequently, positional and warning information is presented to the operator. An alerting mechanism may be used for providing the positional and warning information to the operator. The alerting mechanism may include an audio alert and/or video alert from one or more of a radio system, an automobile horn, a portable device and a travel guidance system. The operator may select the one or more audio/video alerting mechanisms.

Alerts used in the disclosed method and system may be classified as generic or specific. For example, if an operator is far away on right hand side of a lane, a generic alarm may provide warnings to the operator. The generic alarm may be high frequency beeps or an audio message with specific warning such as "You are currently traveling on the right hand shoulder of the roadway". Additionally, the operator may specifically indicate to the lane tracking system that there is no problem, although the position of the automobile may be unusual. For example, the operator may make such an indication when the operator parks the automobile on a roadway to attend a phone call.

Further, the operator may enable/disable one or more functions of the lane tracking system for tracking the automobile with respect to lane markings on the roadway. For example, an operator traveling on a narrow roadway may be presented with frequent triggering of lane alarms and may want to disable the lane tracking system during that portion of a travel.
