A method of checking the quality of traffic disturbance reporting processes records 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. A number of reported conditions is formed from the total number of traffic disturbance reports, and a first statistical frequency distribution of the reported conditions is determined. A total number of reference observations are recorded, 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. A number of actual conditions is formed from the total number of reference observations and a second statistical frequency distribution of the actual conditions is determined. The second statistical frequency distribution is compared with the first statistical frequency distribution, and a quality indicator for the traffic disturbance reporting process is derived from the result of the comparison.
