Method of developing traffic messages
First Claim
1. A method of developing traffic messages comprising:
- obtaining traffic data indicating collected traffic speeds at various locations on a road network, each of said locations represented by a unique traffic location code;
developing a plurality of traffic messages from the traffic data;
obtaining ground truth data indicating ground truth speeds at a subset of said locations on said road network, wherein said ground truth speed representing average speed of vehicles at one of said locations;
for said locations for which ground truth speed has been obtained, computing a traffic quality value comparing said collected traffic speed to said ground truth speed for said location; and
transmitting said traffic messages and traffic quality data representative of said traffic quality values.

Abstract
A method is disclosed for developing traffic messages. The method obtains traffic data indicating collected traffic speeds at various locations on a road network. Traffic messages are developed from the traffic data. The method obtains ground truth data indicating ground truth speeds at a subset of the locations on the road network. The ground truth speed represents average speed of vehicles at one of the locations. For those locations for which ground truth speed has been obtained, the method computes a traffic quality value comparing the collected traffic speed to the ground truth speed for the location. The traffic messages and traffic quality data representative of the traffic quality values are transmitted.
