Abstract

An intelligent traffic safety cone or pylon is placed in a traffic lane of a roadway to mark the beginning or end of a roadway traffic obstruction. The pylon has a GPS sensor disposed at the top of the body portion that rises from the pylon base. A battery is situated within the pylon base providing stabilizing weight. A microprocessor circuit within the pylon body is coupled to the GPS sensor to acquire location data of said pylon to within a resolution of a lane of the roadway. A radio transmitter within the pylon body coupled to the microprocessor provides a radio signal modulated to provide the location data to a central traffic navigation facility. The pylon may have a folding antenna, and may have additional sensors for traffic conditions and weather conditions.

Claims

1. A traffic safety pylon adapted to be used with an intelligent roadway navigation system, the pylon being adapted to be placed in a traffic lane of a roadway to mark the beginning or end of a roadway traffic obstruction;

the pylon comprising

a base;

a body rising up from the base to a top;

a GPS sensor disposed at said top;

a battery situated in said base providing stabilizing weight to said pylon;

a microprocessor circuit within the pylon body and coupled to said GPS sensor to acquire location data of said pylon to within a resolution of a width of said traffic lane;

a radio transmitter in said pylon body coupled to said microprocessor and providing a radio signal modulated to provide said location data to a central traffic navigation facility; and

an antenna coupled to said transmitter and mounted on said pylon body.

2. Traffic safety pylon according to claim 1 wherein said antenna folds out from a storage position concealed within said body to a raised operative position.

3. Traffic safety pylon according to claim 2 wherein said antenna includes switch means for turning the pylon microprocessor circuit and radio transmitter on when the antenna is moved to its raised position and off when the antenna is moved to is storage position.

4. Traffic safety pylon according to claim 1, further comprising a vehicle traffic sensor mounted on said body for detecting density of vehicular traffic at said roadway traffic obstruction.

5. Traffic safety pylon according to claim 1, further comprising a vehicle traffic sensor mounted on said body for detecting average speed of vehicular traffic at said roadway traffic obstruction.

6. Traffic safety pylon according to claim 1, further comprising a weather condition sensor mounted on said body for detecting one or more weather parameters at said roadway traffic obstruction.
