Abstract

The disclosure includes a system and method for providing zone information to a user. The system includes a processor and a memory storing instructions that when executed cause the system to: receive data describing a current location and a travel speed associated with a user; determine a travel status associated with the user based on the current location and the travel speed; create a zone of relevance for the user based on the travel status, the zone of relevance including one or more regions with each region being mapped to one or more regional circles; generate one or more queries for the zone of relevance; retrieve one or more query results that match the zone of relevance using the one or more queries; process the one or more query results to generate zone information relevant to the user; and provide the zone information to the user.

Claims

1. A computer-implemented method comprising:

receiving data describing a current location and a travel speed associated with a user;

determining a travel status associated with the user based on the current location and the travel speed;

creating a zone of relevance for the user based on the travel status, the zone of relevance including one or more regions with each region being mapped to one or more regional circles;

generating one or more queries for the zone of relevance;

retrieving one or more query results that match the zone of relevance using the one or more queries;

processing the one or more query results to generate zone information relevant to the user; and

providing the zone information to the user.

2. The method of claim 1, wherein creating the zone of relevance comprises:

determining a regional angle and a regional length for each region based on the travel status; and

generating the one or more regions based on the regional angle and the regional length.

3. The method of claim 1, wherein creating the zone of relevance comprises:

determining one or more circle centers and one or more radii for the one or more regional circles in each region;

matching each region to the one or more corresponding regional circles that are determined by the one or more circle centers and the one or more radii; and

determining the zone of relevance including the one or more regions with each region being mapped to the one or more corresponding regional circles.

4. The method of claim 1, wherein the one or more queries includes one or more circle queries with each circle query corresponding to one of the one or more regional circles in each region.

5. The method of claim 1, wherein processing the one or more query results comprises:

filtering the one or more query results to remove duplicate data;

filtering the one or more query results to remove data related to a direction opposite to a travel direction associated with the user; and

combining the one or more filtered query results to generate the zone information relevant to the user.

6. The method of claim 1, further comprising:

receiving data describing a travel direction associated with the user;

receiving data describing a local map associated with the current location;

matching the current location to the local map to determine a road type; and

wherein the travel status is further determined based on the road type and the travel direction.

7. The method of claim 1, wherein the zone of relevance is configured based on at least one of a travel direction and a road type.

8. The method of claim 1, wherein the one or more regions include a front region, a left region and a right region.

9. A computer program product comprising a computer usable medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

receive data describing a current location and a travel speed associated with a user;

determine a travel status associated with the user based on the current location and the travel speed;

create a zone of relevance for the user based on the travel status, the zone of relevance including one or more regions with each region being mapped to one or more regional circles;

generate one or more queries for the zone of relevance;

retrieve one or more query results that match the zone of relevance using the one or more queries;

process the one or more query results to generate zone information relevant to the user; and

provide the zone information to the user.

10. The computer program product of claim 9, wherein creating the zone of relevance comprises:

determining a regional angle and a regional length for each region based on the travel status; and

generating the one or more regions based on the regional angle and the regional length.

11. The computer program product of claim 9, wherein creating the zone of relevance comprises:

determining one or more circle centers and one or more radii for the one or more regional circles in each region;

matching each region to the one or more corresponding regional circles that are determined by the one or more circle centers and the one or more radii; and

determining the zone of relevance including the one or more regions with each region being mapped to the one or more corresponding regional circles.

12. The computer program product of claim 9, wherein the one or more queries includes one or more circle queries with each circle query corresponding to one of the one or more regional circles in each region.

13. The computer program product of claim 9, wherein processing the one or more query results comprises:

filtering the one or more query results to remove duplicate data;

filtering the one or more query results to remove data related to a direction opposite to a travel direction associated with the user; and

combining the one or more filtered query results to generate the zone information relevant to the user.

14. The computer program product of claim 9, wherein the computer readable program when executed on the computer causes the computer to also:

receive data describing a travel direction associated with the user;

receive data describing a local map associated with the current location;

match the current location to the local map to determine a road type; and

wherein the travel status is further determined based on the road type and the travel direction.

15. The computer program product of claim 9, wherein the zone of relevance is configured based on at least one of a travel direction and a road type.

16. A system comprising:

a processor; and

a memory storing instructions that, when executed, cause the system to;

receive data describing a current location and a travel speed associated with a user;

determine a travel status associated with the user based on the current location and the travel speed;

create a zone of relevance for the user based on the travel status, the zone of relevance including one or more regions with each region being mapped to one or more regional circles;

generate one or more queries for the zone of relevance;

retrieve one or more query results that match the zone of relevance using the one or more queries;

process the one or more query results to generate zone information relevant to the user; and

provide the zone information to the user.

17. The system of claim 16, wherein the instructions when executed cause the system to create the zone of relevance by:

determining a regional angle and a regional length for each region based on the travel status; and

generating the one or more regions based on the regional angle and the regional length.

18. The system of claim 16, wherein the instructions when executed cause the system to create the zone of relevance by:

determining one or more circle centers and one or more radii for the one or more regional circles in each region;

matching each region to the one or more corresponding regional circles that are determined by the one or more circle centers and the one or more radii; and

determining the zone of relevance including the one or more regions with each region being mapped to the one or more corresponding regional circles.

19. The system of claim 16, wherein the instructions when executed cause the system to process the one or more query results by:

filtering the one or more query results to remove duplicate data;

filtering the one or more query results to remove data related to a direction opposite to a travel direction associated with the user; and

combining the one or more filtered query results to generate the zone information relevant to the user.

20. The system of claim 16, wherein the instructions when executed cause the system to also:

receive data describing a travel direction associated with the user;

receive data describing a local map associated with the current location;

match the current location to the local map to determine a road type; and

wherein the travel status is further determined based on the road type and the travel direction.
