Embodiment Construction
[0040] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] In this embodiment, the Fifth Ring Road of Beijing is used as the positioning road section, which is the research object of this embodiment. In this embodiment, a smart terminal is installed on the vehicle and has a positioning and navigation function. combine Figure 4 It can be seen that a communication connection is established between the smart terminal and the server, which is a mobile communication method in this embodiment, and the smart terminal is authorized by the user to establish a data transmission channel with the server for data transmission. In this embodiment, the server is provided with a congestion analysis module, a congestion information feedback module, and a database. The lane distribution map of the positioning road section and the lane coordinate calibration map of t...

The invention discloses a method for prompting precise positioning of congested lanes at congestion points based on navigation and positioning. The specific steps are: setting a positioning road section, obtaining a lane distribution map and a lane coordinate calibration map of the positioning road section; installing an intelligent terminal on an authorized vehicle, and obtaining in real time The driving speed and corresponding driving coordinates of the authorized vehicles on the positioning road section; compare the driving speeds of all authorized vehicles at the current moment with the previous moment to obtain the set of slowing vehicles; according to the distribution of the driving coordinates of the set of slowing vehicles, obtain the driving Deceleration section: Carry out congestion monitoring and judgment on the traffic deceleration section and the road sections before and after the traffic deceleration section, obtain the congestion section and corresponding congestion information, and feed back the congestion information to the congestion section and the vehicles that are about to enter the congestion section. Beneficial effects: quickly determine the congested section and congested lane without human participation.
Description
technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to a method for prompting precise positioning of congestion points and congested lanes based on navigation and positioning. Background technique [0002] Now everyone has a car, whether driving or riding a motorcycle will encounter traffic jams, especially in the morning and evening rush hours in densely populated cities, such as Beijing. For expressways or highways, traffic jams are generally caused by traffic accidents. Once a traffic accident occurs, the following vehicle will slow down and change lanes, and the distance of the lane change is short and the speed is slow. The following vehicles drive fast, and a second traffic accident may occur here or cause the following vehicles to brake suddenly. It is easy to cause flameout and other situations. For vehicles entering the congested road section, because they do not know the fault point, they can only change...
