Zusammenfassung: | The invention relates to a method and a device for acquiring driving test cycle weight factors based on GIS large data. The acquisition method comprises the following steps: S1, supplementing and correcting the GIS data; S2, processing and matching road information, and constructing a typical city all-road network GIS database; S3, establishing a traffic flow model selection model based on support vector machine; S4, calibrating and calculating a traffic flow model to obtain the traffic flow of the all-road network road; S5, calculating a speed interval weight factor. The method can accurately and objectively calculate the weight factor of each speed interval, and provides technical support for policy making, test design and product development of governments, research institutions and enterprises in relevant fields of driving test cycle extraction. |
