1. A method for storing probe data gathered by a navigation system at a remote server, comprising:

  • receiving data from a plurality of probe vehicles at the remote server;

    determining at least two speed patterns associated with the received data;

    classifying the received data from each of the plurality of probe vehicles according to one of a first speed pattern and a second speed pattern;

    calculating a first number of probe vehicles associated with the first speed pattern;

    calculating a second number of probe vehicles associated with the second speed pattern;

    comparing the first number of probe vehicles associated with the first speed pattern with the second number of probe vehicles associated with the second speed pattern;

    wherein based on the step of comparing the first number of probe vehicles with the second number of probe vehicles, additionally performing the steps of;

    storing the data classified as the first speed pattern in a regular lanes database;

    storing the data classified as the second speed pattern in a carpool lanes database; and

    wherein the data is classified as the first speed pattern if the comparison of the first number of probe vehicles with the second number of probe vehicles determines that the number of probe vehicles associated with the first speed pattern is greater than the number of probe vehicles associated with the second speed pattern.
