Abstract

A traffic analysis system analyzes location data from a plurality of vehicles to determine journeys made by the vehicles. Vehicles may make one or more rest stops during a journey. The traffic analysis system compares rest periods to journey criteria to determine whether a rest period delineates the end of a journey, or whether a rest period is still within the journey. In this way, a plurality of trips can be chained together into a journey to provide more accurate analysis of traffic patterns.

First claim

What is claimed is:

1. A method comprising:
receiving an identification of a first geographic region;
receiving an identification of a second geographic region;
determining a number of vehicle journeys by a plurality of vehicles between the first geographic region and the second geographic region in at least a time interval, by:
receiving location data for the plurality of vehicles, the location data indicative of a succession of a plurality of trips travelled by each vehicle and indicative of at least one rest period of each vehicle wherein the respective vehicle is not moving, each trip in the plurality of trips being separated from a preceding trip by a respective rest period of the at least one rest period;
determining, for each vehicle in the plurality of vehicles, a number of journeys travelled between the first geographic region and the second geographic region by the vehicle, by:
comparing each rest period of the at least one rest period for the vehicle to journey criteria; and
tabulating a number of journeys by the vehicle between the first geographic region and the second geographic region, where one journey includes one or more successive trips of the plurality of trips, each of the successive trips separated from each other by a respective rest period of the at least one rest period which satisfies the journey criteria, and the successive trips together representing travel between the first geographic region and the second geographic region;

generating traffic analysis results based on the determined number of journeys; and
outputting the traffic analysis results to a user to provide the user with information regarding traffic patterns between the two regions.

2. The method of claim 1 , wherein the first geographic region and the second geographic region are different.

3. The method of claim 1 , wherein:
the first geographic region and the second geographic region are a common geographic region; and
determining the number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region comprises determining the number of vehicle journeys which begin and end within the common geographic region.

4. The method of claim 1 , further comprising receiving an identification of a third geographic region, wherein:
the first geographic region, the second geographic region, and the third geographic region are different; and
successive trips together counted as a journey represent travel between the first geographic region and the second geographic region, through the third geographic region.

5. The method of claim 1 , further comprising receiving an identification of a plurality of additional geographic regions, wherein:
the first geographic region, the second geographic region, and the plurality of additional geographic regions are different from each other; and
successive trips together counted as a journey represent travel between the first geographic region and the second geographic region, through at least one of the plurality of additional geographic regions.

6. The method of claim 5 , wherein successive trips together counted as a journey represent travel between the first geographic region and the second geographic region, through each of the plurality of additional geographic regions.

7. The method of claim 1 , wherein determining the number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region comprises:
determining the number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region by summing together each respective tabulated number of journeys by each vehicle between the first geographic region and the second geographic region.

8. The method of claim 7 , wherein:
the determined number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region is representative of a total number of vehicle journeys between the first geographic region and the second geographic region; and
the method further comprises estimating the total number of vehicle journeys between the first geographic region and the second geographic region based on the determined number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region.

9. The method of claim 1 , wherein:
receiving the identification of the first geographic region comprises receiving the identification of the first geographic region as an operator input; and
receiving the identification of the second geographic region comprises receiving the identification of the second geographic region as another operator input.

10. The method of claim 1 , wherein:
the first geographic region is identified as an origin for vehicle journeys;
the second geographic region is identified as a destination for vehicle journeys;
determining the number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region comprises: determining the number of vehicle journeys by the plurality of vehicles from the first geographic region to the second geographic region in at least a time interval.

11. The method of claim 1 , wherein determining the number of vehicle journeys by the plurality of vehicles between the first geographic region and the second geographic region comprises:
determining the number of vehicle journeys as a combination of a first number of vehicle journeys by the plurality of vehicles from the first geographic region to the second geographic region and a second number of vehicle journeys by the plurality of vehicles from the second geographic region to the first geographic region.
