Abstract

A system and method is disclosed for generating and providing assessments of transit network characteristics for specified locations. The system receives a specified location, generates an assessment of the received location, and provides a generated visual representation of the received location to a client system. Determining a location assessment may be based on transit network information related to the distance between a specified location and the nearest point of access/egress on transit network routes that are accessible from the specified location, the frequency at which the transit network routes stop at the point of access/egress on the transit network routes that are accessible from the indicated location, or the transportation mode used for at least one of the transit network routes that are accessible from the specified location. The initial location assessment may be updated periodically, in response to changes in system status, or on demand by user request.

obtaining transit information identifying a plurality of transit access points within a geographical area;

determining a plurality of locations within the geographical area on which to conduct a location assessment;

for each location of the plurality of locations, conducting the location assessment, wherein conducting the location assessment comprises;

inspecting the transit information for the geographical area to determine transit access points within a threshold distance of the location;

for each transit access point of at least some of the transit access points, assigning a weighted value to the transit access point based at least in part on;

a distance between the location and the transit access point, and

a frequency of service on a transit route servicing the transit access point; and

combining the weighted values into a location score for the location;

storing the location score for each location of the plurality of locations within a memory as location score information for the geographical area;

receiving from a computing device, over a communication network, a request for information regarding the geographical area;

transmitting to the computing device, over the communication network, interface instructions configured to output an interface enabling selection of a location from the plurality of locations within the geographical area;

receiving an indication of the location made within the interface;

retrieving the location score of the indicated location, as stored in the memory; and

transmitting the location score of the indicated location to the computing device.

2. The computer-implemented method of claim 1 further comprising obtaining updated transit score information for the geographical area and updating a location score for at least one location of the plurality of locations by repeating the location assessment for the at least one location.

3. The computer-implemented method of claim 2, wherein the location assessment is repeated at predetermined time intervals.

4. The computer-implemented method of claim 2, wherein the location assessment is repeated in response to a user request.

5. The computer-implemented method of claim 1, wherein the indicated location is identified by at least one of a zip code area, a neighborhood, a city, a state, a country, or a geographical region.

6. The computer-implemented method of claim 1, wherein the indicated location is a neighborhood.

7. The computer-implemented method of claim 1, wherein the indicated location is a metropolitan area.

8. The computer-implemented method of claim 1, wherein the location score of the indicated location is presented along with other information about the indicated location.

9. The computer-implemented method of claim 1, wherein the location score of the indicated location is normalized based on a perfect score corresponding to a perfect score location that is different from the indicated location.

10. The computer-implemented method of claim 9, wherein the perfect score location is a city for which transit network information is available.

11. The computer-implemented method of claim 9, wherein the perfect score location comprises multiple cities for which transit network information is available.

12. A computing system comprising:

a memory storing transit information for a geographical area, wherein the transit information identifies a plurality of transit access points within the geographical area; and

a processor configured with computer executable instructions to;

determine a plurality of locations within the geographical area on which to conduct a location assessment;

for each location of the plurality of locations, conduct the location assessment, wherein the location assessment comprises;

inspecting the transit information for the geographical area to determine transit access points within a threshold distance of the location;

for each transit access point of at least some of the transit access points, assigning a weighted value to the transit access point based at least in part on;

a distance between the location and the transit access point, and

a frequency of service on a transit route servicing the transit access point; and

combining the weighted values into a location score for the location;

store the location score for each location of the plurality of locations within the memory as location score information for the geographical area;

receive from a computing device, over a communication network, a request for information regarding the geographical area;

transmit to the computing device, over the communication network, interface instructions configured to output an interface enabling selection of a location from the plurality of locations within the geographical area;

receive an indication of a location made within the interface;

retrieve the location score of the indicated location, as stored in the memory; and

transmit the location score of the indicated location to the computing device.

13. The computing system of claim 12, wherein the processor is configured with computer executable instructions to repeat the location assessment for each location of the plurality of locations at predetermined time intervals.

14. The computing system of claim 12, wherein the indicated location is a zip code area, a neighborhood, a city, a state, a country, or a geographical region.

15. The computing system of claim 12, wherein the indicated location is a neighborhood.
