Abstract

A database of property data is searched based on a location constraint that is determined based on travel time contours constructed for multiple locations of interest. The locations of interest and travel parameters associated therewith are selected by a user. The travel parameters include a maximum travel time for each location. For each location, the travel time contour is constructed based on the travel parameters for the location such that points within the travel time contour have a travel time to the location that is less than or equal to the maximum travel time. The travel time contours are intersected, and the location constraint is based on the intersection.

Claims

1. A non-transitory computer readable medium that stores program code that is configured to, when executed by a computing system, cause the computing system to perform operations comprising:

determining a first location of interest and a second location of interest;

determining travel parameters for the first and second locations of interest, including a first maximum travel time for the first location of interest and a second maximum travel time for the second location of interest;

determining a first travel time contour for the first location of interest based on the travel parameters for the first location of interest;

determining a second travel time contour for the second location of interest based on the travel parameters for the second location of interest;

determining a location constraint based on an intersection of the first travel time contour and the second travel time contour; and

searching a database of property data based on the location constraint.

2. The non-transitory computer readable medium of claim 1, wherein the operations further comprise:

determining a first geographic region to be an inclusive region,

wherein the location constraint is determined based on an intersection of the first geographic region, the first travel time contour, and the second travel time contour.

3. The non-transitory computer readable medium of claim 1, wherein the operations further comprise:

determining a second geographic region to be an exclusive region,

wherein the location constraint is based on a result of subtracting the second geographic region from the intersection of the first travel time contour with the second travel time contour.

4. The non-transitory computer readable medium of claim 1, wherein the operations further comprise:

determining a first geographic region to be an inclusive region; and

determining a second geographic region to be an exclusive region,

wherein the location constraint is a result of subtracting the second geographic region from an intersection of the first geographic region, the first travel time contour, and the second travel time contour.

5. The non-transitory computer readable medium of claim 1,

wherein the searching of the database of property data based on the location constraint comprises returning as search results only properties that are located within a geographic region corresponding to the location constraint.

6. The non-transitory computer readable medium of claim 1,

wherein the travel parameters include a time at which the travel will be undertaken.

7. The non-transitory computer readable medium of claim 1,

wherein the travel parameters include a mode of travel.

8. A method, comprising:

determining a first location of interest and a second location of interest;

determining travel parameters for the first and second locations of interest, including a first maximum travel time for the first location of interest and a second maximum travel time for the second location of interest;

determining a first travel time contour for the first location of interest based on the travel parameters for the first location of interest;

determining a second travel time contour for the second location of interest based on the travel parameters for the second location of interest;

determining a location constraint based on an intersection of the first travel time contour and the second travel time contour; and

searching a database of property data based on the location constraint.

9. The method of claim 8, further comprising:

determining a first geographic region to be an inclusive region; and

determining a second geographic region to be an exclusive region,

wherein the location constraint is a result of subtracting the second geographic region from an intersection of the first geographic region, the first travel time contour, and the second travel time contour.

10. The method of claim 8,

wherein the searching of the database of property data based on the location constraint comprises returning as search results only properties that are located within a geographic region corresponding to the location constraint.

11. The method of claim 8,

wherein the travel parameters include a time at which the travel will be undertaken.

12. The method of claim 8,

wherein the travel parameters include a mode of travel.

13. A computing system, comprising:

a processor;

a memory having program code stored thereon, the program code being configured to, when executed by the processor, cause the computing system to perform operations comprising;

determining a first location of interest and a second location of interest;

determining travel parameters for the first and second locations of interest, including a first maximum travel time for the first location of interest and a second maximum travel time for the second location of interest;

determining a first travel time contour for the first location of interest based on the travel parameters for the first location of interest;

determining a second travel time contour for the second location of interest based on the travel parameters for the second location of interest;

determining a location constraint based on an intersection of the first travel time contour and the second travel time contour; and

searching a database of property data based on the location constraint.

14. The computing system of claim 13, wherein the operations further comprise:

determining a first geographic region to be an inclusive region; and

determining a second geographic region to be an exclusive region,

wherein the location constraint is a result of subtracting the second geographic region from an intersection of the first geographic region, the first travel time contour, and the second travel time contour.

15. The computing system of claim 13,

wherein the searching of the database of property data based on the location constraint comprises returning as search results only properties that are located within a geographic region corresponding to the location constraint.

16. The computing system of claim 13,

wherein the travel parameters include a time at which the travel will be undertaken.

17. A non-transitory computer readable medium that stores program code that is configured to, when executed by a computing system, cause the computing system to perform operations comprising:

determining a location of interest;

determining travel parameters for the location of interest, including a maximum travel time;

determining a travel time contour for the location of interest based on the travel parameters,

determining a location constraint based on the travel time contour; and

searching a database of property data based on the location constraint.

18. The non-transitory computer readable medium of claim 17, wherein the operations further comprise:

determining a first geographic region to be an inclusive region; and

determining a second geographic region to be an exclusive region,

wherein the location constraint is a result of subtracting the second geographic region from an intersection of the first geographic region and the travel time contour.

19. The non-transitory computer readable medium of claim 17,

wherein the searching of the database of property data based on the location constraint comprises returning as search results only properties that are located within a geographic region corresponding to the location constraint.

20. The non-transitory computer readable medium of claim 17,

wherein the travel parameters include a time at which the travel will be undertaken.
