Differentiation of probe reports based on quality
First Claim
1. A method comprising:
- receiving, by a processor, a probe report from a probe sensor, wherein the probe report comprises data indicative of a travel condition;
determining, by the processor, whether the probe report emanated from within a redefined boundary associated with a parking lot, a loading zone, or a combination thereof;
determining, by the processor, whether the probe report meets or exceeds a predefined speed threshold;
determining, by the processor, whether a heading contained in the probe report is compatible with a road direction; and
identifying, by the processor, the probe report as being suitable for use in modeling the travel condition if the probe report does not emanate from within the predefined boundary, the probe report meets a predefined speed threshold, and the probe report contains a heading that is compatible with the road direction.

Abstract
Methods for differentiating high quality probe reports in a plurality of probe reports include: (a) receiving, by a processor, a probe report from a probe source, wherein the probe report includes data indicative of a travel condition; (b) determining, by the processor, whether the probe report satisfies a criterion indicative of high quality data; and (c) identifying, by the processor, the probe report as being (i) suitable for use in modeling the travel condition if the probe report satisfies the criterion, or (ii) unsuitable for use in modeling the travel condition if the probe report does not satisfy the criterion. Systems for differentiating high quality probe reports in a plurality of probe reports are described.

10. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following; receive a probe report from a probe sensor, wherein the probe report comprises data indicative of a travel condition; determine whether the probe report emanated from a location within a predefined boundary; determine whether the probe report emanated from a relevant transportation mode, wherein the relevant transportation mode is a car, truck, or bus; determine whether a time difference between consecutive probe reports from the probe sensor exceeds a predefined frequency submission; and identify the probe report as being suitable for use in modeling the travel condition if the probe report emanated a location within a predefined boundary, the probe report emanated from a relevant transportation mode, and a time difference between consecutive probe reports exceeds the predefined frequency submission. - View Dependent Claims (11, 12, 13)

14. In a non-transitory computer-readable storage medium having stored therein data representing instructions executable by a programmed processor, the storage medium comprising instructions for:
-
receiving a probe report from a probe sensor, wherein the probe report comprises data indicative of a travel condition; determining a probability of map matching the probe report; identifying the probe report as being suitable for use in modeling the travel condition if the probe report the probability of map matching is greater than or equal to a predefined threshold; and outputting the probe report for modeling in response to the probe report being suitable for use in modeling the travel condition. - View Dependent Claims (15, 16, 17, 18, 19)
