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.

Abstract
A remote server receives traffic data from a plurality of probe vehicles traveling on roadways. The remote server stores the received traffic data in a regular lane database and/or a carpool lane database. The remote server differentiates the received traffic data for storage in the appropriate database based on the number of probe vehicles associated with each speed pattern observed within the received traffic data.

9. A method for differentiation of collected probe data from a navigation system at a remote server in communication with a regular lanes database and a carpool lanes database, comprising:
-
receiving probe data from a plurality of vehicles at the remote server; fitting the received probe data to one of a first speed pattern and a second speed pattern; determining a first number of vehicles associated with the received probe data fitting the first speed pattern; determining a second number of vehicles associated with the received probe data fitting the second speed pattern; comparing the first number of vehicles fitting the first speed pattern with the second number of vehicles fitting the second speed pattern; determining, based on the comparison of the first number of vehicles with the second number of vehicles, the smaller of the first number and the second number; wherein the received probe data associated with the smaller of the first number and the second number is stored in the carpool lanes database; and wherein the remaining received probe data is stored in the regular lanes database. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for sorting traffic data from a plurality of vehicles with a navigation system at a remote server;
- comprising;
receiving traffic data from a plurality of vehicles at the remote server; determining whether the received traffic data corresponds to at least two speed patterns; calculating a first number of vehicles associated with a first speed pattern; calculating a second number of vehicles associated with a second speed pattern; comparing the first number of vehicles associated with the first speed pattern with the second number of vehicles associated with the second speed pattern; determining, based on the comparison of the first number of vehicles with the second number of vehicles, the smaller of the first number and the second number and the larger of the first number and the second number; storing a first portion of the received traffic data associated with the larger of the first number of vehicles and the second number of vehicles in a regular lanes database; and storing a second portion of the received traffic data associated with the smaller of the first number of vehicles and the second number of vehicles in a carpool lanes database. - View Dependent Claims (18, 19, 20, 21, 22, 23)
