The invention discloses a method for evaluating traffic operational conditions of a highway based on multisource data fusion and relates to the technical field of evaluation of the traffic operational conditions. The traffic operational conditions of the highway based on multisource data fusion are evaluated in combination with a large amount of GPS (global positioning system) data acquired and accumulated by a floating car acquisition system and a large amount of toll data acquired and accumulated by a highway toll system by utilizing data of fixed car detectors, and an obtained evaluation result of the traffic operational condition of the highway is more accurate and wider in coverage range, so that a defect of insufficient arrangement of car detectors can be made up for, road network monitoring range and system can be performed, traffic jams on roads can be accurately discovered in time, and the safety and efficiency of road traffic can be guaranteed; moreover, the toll data and floating car data are all based on existing toll system and floating car GPS management system, and the additional data acquisition cost is zero, so that the method provided by the embodiment of the invention is good in economy and promotion prospect.
