Abstract

System and method for analyzing position data from a vehicle equipped with a geographical position system to determine if the vehicle has adhered to a predetermined schedule, where the vehicle is scheduled to arrive at each one of a plurality of predetermined locations during a corresponding predetermined time window, the position data identifying a specific geographical location of the vehicle at a specific point in time. Position data from the vehicle is collected as the vehicle travels to the plurality of different locations, the position data identifying a specific geographical location of the vehicle at a specific point in time. Then the position data is analyzed to determine whether the vehicle was at each predetermined location during the corresponding predetermined time window. An exception report is automatically generated for each instance that the vehicle was not at one of the plurality of predetermined locations during the corresponding time window.

Claims

1. A system for analyzing position data from a vehicle equipped with a geographical position system to determine if the vehicle has adhered to a predetermined schedule, where the vehicle is scheduled to arrive at each one of a plurality of predetermined locations during a corresponding predetermined time window, the position data identifying a specific geographical location of the vehicle at a specific point in time, the system comprising:

(a) a non-transitory memory remote from the vehicle, in which a plurality of machine instructions are stored;

(b) a data link for communicating the position data collected at the vehicle while operating the vehicle; and

(c) a processor remote from the vehicle and logically coupled to the memory and to the data link, said processor executing the machine instructions to carry out a plurality of functions, including;

(i) analyzing the position data to determine whether the vehicle was at each predetermined location during the corresponding predetermined time window; and

(ii) automatically generating an exception report for each instance that the vehicle was not at one of the plurality of predetermined locations during the corresponding time window; and

(iii) analyzing the exception reports to determine a cause for the exceptions, and a course of action for improving ongoing vehicle operations.

2. The system of claim 1, wherein the “

plurality of functions further include automatically delivering each exception report to a dispatcher responsible for the vehicle via at least one of an email message, an instant message, a voicemail message, or a popup window on a computer assigned to the dispatcher.

3. The system of claim 1, wherein the plurality of functions further include enabling a dispatcher responsible for the vehicle to define the temporal window for each location, such that each temporal window can be identical in duration or different in duration.

4. The system of claim 1, wherein the machine instructions, when executed by a processor, analyze the position data to determine whether the vehicle was at each predetermined location during the corresponding predetermined time by performing the steps of:

(a) for each time window, determining an actual geographic position of the vehicle during that time window; and

(b) for each time window, comparing the actual geographic position of the vehicle with the plurality of predetermined locations, such that an exception report will be generated when the actual geographic position of the vehicle during the time window does not correspond to one of the plurality of predetermined locations.

5. The system of claim 1, wherein the machine instructions, when executed by a processor, analyze the position data to determine whether the vehicle was at each predetermined location during the corresponding predetermined time by performing the steps of:

(a) for each of the plurality of predetermined locations, determining an arrival time that the vehicle arrived at the location; and

(b) for each of the plurality of predetermined locations, comparing the arrival time with the corresponding time window for that location, such that an exception report will be generated when the arrival time is not within the corresponding time window.

6. A method for analyzing position data from a vehicle equipped with a geographical position system to determine if the vehicle has adhered to a predetermined schedule, where the vehicle is scheduled to arrive at each one of a plurality of predetermined locations during a corresponding predetermined time window;

the method comprising the steps of;

(a) collecting position data from the vehicle as it travels to the plurality of different locations, the position data identifying a specific geographical location of the vehicle at a specific point in time;

(b) analyzing the position data to determine whether the vehicle was at each predetermined location during the corresponding predetermined time window; and

(c) automatically generating an exception report for each instance that the vehicle was not at one of the plurality of predetermined locations during the corresponding time window, except when the position data indicates that the vehicle arrived at the predetermined location early, in which case no exception report will be generated for an early arrival.

7. The method of claim 6, wherein the exception reports identify the driver.

8. The method of claim 6, wherein the exception reports identify the route driven.

9. The method of claim 6, wherein the exception reports are analyzed to determine viability of the route.

10. A method for analyzing position data from a vehicle equipped with a geographical position system to determine if the vehicle has adhered to a predetermined schedule, where the vehicle is scheduled to arrive at each one of a plurality of predetermined locations during a corresponding predetermined time window;

the method comprising the steps of;

(a) collecting position data from the vehicle as it travels to the plurality of different locations, the position data identifying a specific geographical location of the vehicle at a specific point in time;

(b) after the vehicle has completed its predetermined schedule, analyzing the position data to determine whether the vehicle was at each predetermined location during the corresponding predetermined time window; and

(c) automatically generating an exception report for each instance that the vehicle was not at one of the plurality of predetermined locations during the corresponding time window.

11. The method of claim 10, wherein the step of comparing the actual geographic position of the vehicle with the plurality of predetermined locations comprises the step of ignoring any actual geographic position of the vehicle if the position data collected from the vehicle indicates that the vehicle arrived at the predetermined location corresponding to the specified time window at an earlier point in time, such that no exception report will be generated when the vehicle arrived at the corresponding predetermined location early.

12. The method of claim 10, wherein the step of analyzing the position data to determine whether the vehicle was at a predetermined location during a predetermined time window comprises the steps of:

(a) for each of the plurality of predetermined locations, determining an arrival time that the vehicle arrived at the location; and

(b) for each of the plurality of predetermined locations, comparing the arrival time with the corresponding time window for that location, such that an exception report will be generated when the arrival time is not within the corresponding time window.

13. The method of claim 12, wherein the step of comparing the arrival time with the corresponding time window for that location comprises the step of ignoring any arrival time that is earlier than the corresponding time window, such that no exception report will be generated for an early arrival time.
