Determining exposure to an outdoor display unit

1. A method, comprising:

identifying a geographic location of a mobile display unit configured to display information in an outdoor environment;

obtaining data relating to a number of unique mobile device users identified within a predetermined distance of the mobile display unit at the geographic location during a first period of time;

identifying, based on the obtained data, a first number of people within the predetermined distance of the mobile display unit at the geographic location during the first period of time;

correlating the first number of people with a previously determined total number of people within the predetermined distance of the mobile display unit at the geographic location during a second period of time and associated with a previously determined number of unique mobile device users within the predetermined distance of the mobile display unit at the geographic location during the second period of time, wherein the first period of time is later than the second period of time; and

determining, based on the correlating, an estimated total number of people within the predetermined distance of the mobile display unit at the geographic location during the first period of time.

2. The method of claim 1 , wherein determining the estimated total number of people within the predetermined distance of the mobile display unit at the geographic location is further based on at least one of a time of day the mobile display unit is at the geographic location, a day of the week the mobile display unit is at the geographic location, and weather when the mobile display unit is at the geographic location.

3. The method of claim 1 , wherein the mobile display unit is mounted to a vehicle.

4. The method of claim 1 , wherein identifying the geographic location of the mobile display unit includes obtaining GPS data of the mobile display unit corresponding to the geographic location.

5. The method of claim 4 , wherein the GPS data corresponds to a number of different geographic locations of the mobile display unit recorded over a period of time.

6. The method of claim 5 , wherein the previously determined number of unique mobile device users corresponds to the unique mobile device users identified within the predetermined distance at each of the geographic locations during the second period of time.

7. The method of claim 1 , further comprising determining estimated demographic details of the estimated total number of people.

8. The method of claim 7 , wherein determining the estimated demographic details includes correlating the estimated total number of people with previously determined demographic details of the previously determined total number of people.

9. A system comprising:

one or more processors; and

one or more non-transitory computer-readable media containing instructions which, in response to being executed by the one or more processors, cause the system to perform operations comprising:

identifying a geographic location of a mobile display unit structured to display information in an outdoor environment;

identifying unique mobile device users within a predetermined distance of the mobile display unit at the geographic location during a first period of time;

identifying a first number of people within the predetermined distance of the mobile display unit at the geographic location during the first period of time;

correlating the first number of people with a previously determined total number of people within the predetermined distance of the mobile display unit at the geographic location during a second period of time and associated with a previously determined number of unique mobile device users within the predetermined distance of the mobile display unit at the geographic location during the second period of time, wherein the first period of time is later than the second period of time; and

determining, based on the correlating, an estimated total number of people within the predetermined distance of the mobile display unit at the geographic location during the first period of time.

10. The system of claim 9 , wherein the operations further comprise obtaining GPS data of the mobile display unit corresponding to the geographic location.

11. The system of claim 9 , wherein the operations further comprise determining estimated demographic details of the estimated total number of people.

12. The system of claim 9 , wherein the predetermined distance corresponds to a maximum distance from which content provided on a screen of the mobile display unit may be viewed.

13. The system of claim 9 , wherein the mobile display unit is mounted to a vehicle.

14. One or more non-transitory computer-readable media containing instructions which, in response to being executed by one or more processors, cause a system to perform operations comprising:

identifying a geographic location of a mobile display unit structured to display information in an outdoor environment;

identifying a number of unique mobile device users within a predetermined distance of the mobile display unit at the geographic location during a first period of time; and

determining an estimated total number of people within the predetermined distance of the mobile display unit at the geographic location during the first period of time by comparing the number of unique mobile device users identified within the predetermined distance of the mobile display unit at the geographic location during the first period of time with a previously determined total number of people within the predetermined distance of the mobile display unit at the geographic location during a second period of time which includes a predetermined number of unique mobile device users within the predetermined distance of the mobile display unit at the geographic location during the second period of time, wherein the first period of time is later than the second period of time.

15. The computer-readable media of claim 14 , wherein the operations further comprise obtaining GPS data corresponding to the geographic location.

16. The computer-readable media of claim 14 , wherein the operations further comprise determining estimated demographic details of the estimated total number of people.

17. The computer-readable media of claim 14 , wherein the operations further comprise:

determining one or more of time of day, weekday, and weather at the geographic location when the unique mobile device users within the predetermined distance of the mobile display unit are identified;

comparing one or more of the determined time of day, weekday, and weather at the geographic location when the unique mobile device users within the predetermined distance of the mobile display unit are identified with at least one of a previously determined time of day, weekday, and weather at the geographic location corresponding to the previously determined total number of people; and

accounting for the comparison between the determined time of day, weekday, and weather at the geographic location when the unique mobile device users within the predetermined distance of the mobile display unit are identified with at least one of the previously determined time of day, weekday, and weather at the geographic location corresponding to the previously determined total number of people in the estimated total number of people.
