1. A method for merging imprecisely localized traffic reports with precisely localized traffic data, comprising the following steps:
obtaining, by a traffic determination device, an imprecisely localized traffic report indicating a disturbance within a region between a first point and a second point; obtaining, by the traffic determination device, a precise traffic report corresponding to a region between a third point and a fourth point, wherein the region between the third point and the fourth point at least partially overlaps the region between the first point and the second point; determining, by the traffic determination device, a first portion between the first point and the second point where the precise traffic report confirms the imprecisely localized traffic report, a second portion between the first point and the second point where the precise traffic report refutes the imprecisely localized traffic report, and a third portion between the first point and the second point where the precise traffic report neither confirms nor refutes the imprecisely localized traffic report; estimating, by the traffic determination device, locations of two endpoints for the reported disturbance by solving an extremum problem based on applying weighting criteria to the first, second, and third portions; and merging, by the traffic determination device, the precise traffic report with the imprecisely localized traffic report between the estimated locations of the two endpoints, wherein the merging includes giving priority to the precise traffic report at locations where the precise traffic report conflicts with the imprecisely localized traffic report; and providing, by the traffic determination device, the result of the merging as a traffic situation estimate. |
