Method and apparatus for publishing road event messages

An apparatus for publishing a road event message comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more programs,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• monitor a confidence metric for a road event detected on a geographic location;
• publish a road event message indicating the road event when the confidence metric is greater than an upper threshold of a hysteresis that is lower than one;
• and
• cancel the road event message when the confidence metric is less than a lower threshold of the hysteresis that is higher than zero,
• wherein the upper threshold of the hysteresis is lower than 0.6, and the lower threshold of the hysteresis is higher than 0.4.

A non-transitory computer-readable storage medium for publishing a road event message, carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:

• querying a geographic database for a hysteresis associated with a geographic location;
• publishing a road event message to indicate a road event detected on the geographic location when a confidence metric of the road event is greater than an upper threshold of the hysteresis that is lower than one;
• and
• cancelling the road event message when the confidence metric of the road event is less than a lower threshold of the hysteresis that is higher than zero,
• wherein the upper threshold of the hysteresis is lower than 0.6, and the lower threshold of the hysteresis is higher than 0.4.
