Patent ID: 8144032

Claim:
A quality checking method for traffic disturbance reporting processes, the method comprising the acts of: receiving, by a computer from a service provider, a total number of traffic disturbance reports generated by a traffic disturbance reporting process, which traffic disturbance reports each relate to at least one defined reporting time period and at least one defined reporting route segment, over a predefined analyzing time period and a predefined analyzing range; forming, by the computer, a number of reported conditions from the total number of traffic disturbance reports; generating, by the computer, a first statistical frequency distribution of the reported conditions; recording, by the computer, a total number of reference observations made by at least one measuring vehicle which each relate to at least one defined observation time period and at least one defined observation route segment, within the analyzing time period and within the analyzing range; forming, by the computer, a number of actual conditions from the total number of reference observations made by the at least one measuring vehicle; generating, by the computer, a second statistical frequency distribution of the actual conditions; comparing, by the computer, the second statistical frequency distribution with the first statistical frequency distribution; and generating, by the computer, a quality indicator for the traffic disturbance reporting process from a result of the comparison.
