Road transport vehicle segmented speed limit reminding method and system based on cloud computing

The invention discloses a road transport vehicle segmented speed limit reminding method and system based on cloud computing, and relates to the technical field of cloud computing, personalized transport route planning is performed according to different transport conditions, and according to the set personalized transport route, real-time positions of transport vehicles and key coordinate points on the transport route are cyclically traversed, so that the speed limit of the transport vehicles can be reminded. The method comprises the steps of determining a road section where a transport vehicle is located, based on the position relation between a key coordinate point and a speed limiting point on the road section and the position relation between a real-time position and the key coordinate point, achieving real-time segmented speed limiting reminding and real-time overspeed reminding of the transport vehicle in combination with speed limiting point information, and achieving real-time speed limiting reminding
