Abstract

An interactive street safety map system for internet, GPS, and mobile users is disclosed. The system is designed to identify crime and traffic accidents information at street level. Each street segment on the map indicates low to high density of crime and traffic accidents in different colors in order to improve public perception of safety on each of the streets displayed. The system includes crime and traffic accident data, and the system users can query the data for their interest locations, crime types, crime date and time of occurrence, and the number of crime incidents and traffic accidents. Ultimately, the online street safety map allows users to choose relatively low risk of crime and traffic accident streets for their own safety. The system harvests crime and traffic information data from police departments through Computer-Aided Dispatch (CAD), Recorded Management Systems (RMS), and other crime and traffic information sharing services.

Claims

1. A computer system for displaying event data on a street map, comprising:

a screen display;

a memory;

a processor;

a network interface;

a GPS receiver; and

a program that, when loaded in to the memory and executed by the processor, causes the processor to;

determine a user'"'"'s current location using the GPS receiver;

import data from another computer through the network interface;

from the imported data, extract event data comprising location near the user'"'"'s current location;

separate streets into street segments at intersections with other streets;

associate the extracted event data with a closest street segment; and

generate and display a map that illustrates the extracted event data on the associated closest street segment.

2. The computer system of claim 1, wherein the program further causes the processor to accumulate event data for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.

3. The computer system of claim 2 wherein the data is imported from computer aided dispatch or recorded management systems.

4. The computer system of claim 3 wherein the data imported is crime event data.

5. The computer system of claim 3 wherein the data imported is traffic accident event data.

6. The computer system of claim 2 wherein the event data includes type of event, and program further causes the processor to accumulate event data matching a user selected type of event for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.

7. The computer system of claim 2 wherein the event data includes occurrence time of the event, and program further causes the processor to accumulate event data matching a user selected range of occurrence time for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.

8. A method of displaying event data comprising:

(a) determining a user'"'"'s current location;

(b) importing data from a computer through a network interface;

(c) from the imported data, extracting event data comprising location near the user'"'"'s current location;

(d) separating streets into street segments at intersections with other streets;

(e) associating the extracted event data with a closest street segment; and

(f) creating a map that illustrates the extracted event data on the associated closest street segment.

9. The method of claim 8 wherein the user'"'"'s current location is determined from a GPS receiver.

10. The method of claim 8, further comprising accumulating event data for a plurality of events associated with the closest street segment and generating and displaying the closest street segment to indicate the number of events accumulated.

11. The method of claim 8, wherein the data is imported from computer aided dispatch or recorded management systems.

12. The method of claim 8, wherein the data imported is crime event data.

13. The method of claim 8, wherein the data imported is traffic accident event data.

14. The method of claim 8, wherein the event data includes type of event, and the method further comprising accumulating event data matching a user selected type of event for a plurality of events associated with the closest street segment and creating a map that illustrates the closest street segment indicating the number of events accumulated.

15. The method of claim 8, wherein the event data includes occurrence time of the event, and the method further comprising accumulating event data matching a user selected range of occurrence time for a plurality of events associated with the closest street segment and creating a map that illustrates the closest street segment indicating the number of events accumulated.

16. A non-transient computer readable storage media comprising a program that, when loaded in to memory and executed by a processor in a computer, causes the processor to:

determine a user'"'"'s current location using a GPS receiver;

import data from another computer through a network interface;

from the imported data, extract event data comprising location near the user'"'"'s current location;

separate streets into street segments at intersections with other streets;

associate the extracted event data with a closest street segment; and

generate and display a map that illustrates the extracted event data on the associated closest street segment.

17. The computer readable storage media of claim 16, wherein the program further causes the processor to accumulate event data for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.

18. The computer readable storage media of claim 16, wherein the event data includes type of event, and program further causes the processor to accumulate event data matching a user selected type of event for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.

19. The computer readable storage media of claim 16, wherein the event data includes occurrence time of the event, and program further causes the processor to accumulate event data matching a user selected range of occurrence time for a plurality of events associated with the closest street segment and generate and display the closest street segment to indicate the number of events accumulated.
