Problems solved by technology

Due to this strong correlation, this kind of calculation must be realized by the same device or the same computing group, which leads to a large amount of calculation for a single computer, and the correlation between the two calculation results is too large, and it can only be calculated sequentially. , resulting in problems such as large computational complexity and large delay

example 1

[0204] The method for calculating the target speed of the vehicle provided in this example can be applied to the Internet of Vehicles. The Internet of Vehicles system uses V2X and Mobile Edge Computing (MEC) technology to ensure driving safety and improve traffic efficiency. V2X is a general term for V2V (vehicle), V2I (infrastructure), V2N (network), and V2P (pedestrian). X can be considered to represent everything, vehicles communicate with vehicles, roadside facilities, networks, pedestrians, etc., exchange information with each other, realize multiple applications of human-vehicle-road collaboration, and improve traffic safety and efficiency.

[0205] MEC server, which can use the wireless access network to provide services required by Internet Technology (IT) and cloud computing functions for telecom users nearby, thereby creating a carrier-class service environment with high performance, low latency and high bandwidth, and accelerating the network The fast download of va...

Abstract

Embodiments of the invention provide a target speed calculation method, a mobile edge calculation server and a storage medium. The target speed calculation method comprises the steps of determining whether an (i+1)th vehicle adjacent to an ith vehicle meets a predetermined boundary condition or not, wherein i is a positive integer; and when the (i+1)th vehicle meets the predetermined boundary condition, determining that the ith vehicle is a boundary for dividing a vehicle group; dividing the vehicle group on the basis of the boundary; and calculating target speeds of the vehicles in the vehicle group by the divided vehicle group according to a first risk threshold value corresponding to the vehicle group.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a target speed calculation method, a mobile edge computing server and a storage medium. Background technique [0002] With the rapid development of road traffic, there is currently a speed guidance scheme, which is mostly used near the intersection of traffic lights. According to the phase of the traffic lights at the intersection, the suggested speed is issued to the vehicle so that the vehicle can pass the intersection without waiting. [0003] For the entire road section, the change of vehicle speed will affect the driving state of the vehicle behind, especially on urban roads with dense vehicles. The traffic conditions in the area have a certain impact. When calculating the speed of the leading vehicle in the prior art, the target speed of each vehicle is generally calculated from front to back directly based on conditions such as the distance between adjacent v...
