First Claim
Patent Images
1. A collaborative traffic monitoring system for use in a vehicle, the system comprising:
- an input for receiving GPS location data for the vehicle from a GPS module;
a processing unit arranged to compile speed data for the vehicle using the GPS location data;
a wireless transmitter arranged to broadcast the speed data;
a wireless receiver arranged to receive third party speed data from other vehicles; and
an output to a display device arranged to display data indicative of road speeds for a plurality of road samples ahead of the vehicle, the road speed for each road sample being computed based on the third party speed data received.

Abstract
A collaborative traffic monitoring method is described. In an embodiment, a collaborative traffic monitoring system for use in a vehicle comprises an input for receiving GPS location data and a processing unit which generates speed data for a vehicle based on the received GPS location data. The system also includes a transmitter which broadcasts the speed data and a receiver which receives speed data broadcast by other vehicles. The received speed data is then used to display an indication of the road speeds ahead.
