Problems solved by technology

But it ignores the driver's driving style for a specific car model
The driver's individual needs and user experience index cannot be guaranteed, and the driver does not gain a sense of participation if the driver is only regarded as a passenger

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023]The patent of the invention is for the optimization of traffic flow in local areas, and now the Yangtze River Bridge is used as the optimized road section. When there is a stop-and-go traffic flow phenomenon in this road section, and the front and rear vehicles are in a state of following each other. First, through GPS information, a historical traffic database can be generated. The historical traffic database contains the historical driving records of each vehicle. By extracting the driving data of the following state of the following vehicle and the corresponding leading vehicle, the driving style characteristics of the following vehicle can be identified through the least squares method, so that the Its classification obtains the respective driving characteristics of several common drivers who drive the car. In this way, the driving parameters are marked. And th...

Abstract

The invention discloses a local traffic flow optimization system based on a multi-vehicle longitudinal car-following state. The method comprises steps of firstly, using the least square method to identity driver character parameters; dividing drivers into aggressive, steady and conservative types; calibrating driving behaviors of the steady type drivers to be good car-following parameters; then, through dichotomy method, acquiring the degree that drivers accept suggestions and reminding drivers to improve the car-following behaviors; and guiding drivers to develop good driving habits step by step. According to the invention, based on drivers with different characters and different car-following styles, driving suggestion degrees that special drivers can accept are provided; drivers are advised to keep normal driving; by improving driving behaviors of drivers in the micro level, traffic flows in local regions are optimized in the macro level.

Description

technical field [0001] The invention belongs to the technical field of public transportation, in particular to a multi-vehicle longitudinal car-following technology facing local traffic flow. The present invention proposes a traffic flow optimization method in a local area by learning the historical driving data of drivers of different personality types and vehicles of different models stored in the cloud, which is suitable for traffic jams where stop-and-go traffic often occurs. Background technique [0002] With the sustained and rapid economic and social development, China's car ownership continues to show a trend of rapid growth. At the same time, with the development of cities, road traffic congestion in some areas (Yangtze River Bridge, urban tunnels, etc.) is still very serious. [0003] Based on this, it is urgent to carry out research on traffic flow optimization in local areas. Due to the different personalities of the drivers and the different types of vehicles,...
