Problems solved by technology

[0004] At present, the settings of most dedicated lanes for connected vehicles are static. Static dedicated lanes for connected vehicles cannot dynamically select the location of dedicated lanes in real time according to the penetration rate of connected vehicles. On the one hand, when the penetration rate of connected vehicles is low, the setting Dedicated lanes for connected vehicles tend to waste road resources; on the other hand, when the location of dedicated lanes for connected vehicles does not match the current penetration rate of connected vehicles in each lane, it is easy to cause more lane-changing conflicts and reduce traffic flow. security of operation

Embodiment Construction

[0041] In this example, if figure 1 As shown, a dynamic control method for dedicated networked vehicle lanes based on penetration rate is carried out according to the following steps:

[0042] Step 1: Evenly distribute intelligent light-emitting road studs on the traffic markings of each lane. The intelligent light-emitting road studs include: solar power supply module, road stud WiFi module, LED light-emitting module, and controller; Luminous road stud power supply;

[0043]Geomagnetic vehicle detectors are evenly installed at the upstream section of each lane from the network-connected vehicle dedicated lane setting area L, and the geomagnetic vehicle detectors are used to collect T 0 is the total number of vehicles entering each lane in the current time period with a fixed time interval, denoted as {Q i |i=1,2,...,n}, where i represents the number of the lane, n represents the total number of lanes, Q i Indicates the total number of vehicles entering the i-th lane in th...

Abstract

The invention discloses a dynamic control method for network-connected vehicle special lanes based on permeability, the steps of which include: 1 collecting the total number of vehicles entering each lane in the current time period and the number of network-connected vehicles; 2 judging whether the current time period needs to be set 3. Use the algorithm to determine the lane number of the dedicated lane for connected vehicles in the current time period; 4. Send the dedicated lane number for connected vehicles to connected vehicles on the road section, and at the same time control the intelligent Luminous road studs are illuminated; 5. Repeat the above steps to determine the lane number of the dedicated lane for networked vehicles in the next time period. The invention can dynamically select the position of the dedicated lane for the networked vehicle in real time according to the penetration rate of the networked vehicle of each lane, reduce the number of necessary lane changes of vehicles, reduce the conflict of lane change between vehicles, and improve the safety and traffic safety of traffic flow operation. flow efficiency.

Description

technical field [0001] The invention belongs to the application field of intelligent networked driving, and specifically relates to a dynamic control method for a dedicated lane for networked vehicles based on permeability. Background technique [0002] With the realization of 5G and the development of networked autonomous driving technology, road traffic is in the process of developing from traditional traffic to fully intelligent traffic. The proportion of networked vehicles will gradually increase in the future traffic composition, but due to the impact of objective conditions Affected by the impact, the mixed state of networked vehicles and human-driven vehicles will exist for a certain period of time in the future, which makes it difficult to realize the advantages of networked automatic driving technology in the short term. And in the mixed traffic environment, due to the frequent interaction between connected vehicles and human-driven vehicles, on the one hand, it aff...
