Embodiment Construction
[0042] The present invention provides a method for establishing a spring-like car-following model based on quantum gates and adaptive control. In order to make the purpose of the present invention, technical solutions and effects clearer and clearer, the present invention is further described in detail with reference to the accompanying drawings. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.
[0043] In this embodiment, the studied car-following model is as figure 1 , figure 2 , the car-following model of a spring-like vehicle is used in the present invention. When the following vehicle is too close to the vehicle in front, the following vehicle will slow down to keep a safe distance away from the vehicle in front. When the following car is too far away from the front car, the following car will accelerate to approach the front car, as if there is a spring connecte...

The invention discloses a method for modeling a similar-spring vehicle following based on a quantum gate and adaptive control. The method includes the following steps: in accordance with detailed conditions of a following vehicle and a proceeding vehicle, modeling the similar-spring vehicle following; introducing velocity difference between the proceeding vehicle and the following vehicle as a feedback amount to arrange feedback controlling conditions so as to stabilize the following vehicle speedwise; replacing parameters that are difficult to measure in a similar-spring vehicle following model by introducing adaptive controlling conditions; when the proceeding vehicle decelerates or breaks down due to certain reasons, in accordance with velocities of the following vehicle and the proceeding vehicle and a distance factor between two vehicles, arranging driveway changing and detouring rules of the following vehicle; the method adopts adaptive control, feedback control and driveway changing control to optimize the vehicle following system model, which mitigates traffic congestion, reduces vehicle delays, increases usage rate of traffic road network, reduces tail gas discharge and noise pollution and energy consumption, provides necessary traffic conditions information to road users in time, and increases traffic safety.
Description
technical field [0001] The invention relates to a modeling method for establishing a car-following model of a vehicle, in particular to a method for establishing a spring-like vehicle car-following model based on quantum gates and adaptive control. Background technique [0002] At the end of the 1940s, the economy developed rapidly, and the increasingly serious traffic problems forced many countries to start researching the basic theory of traffic flow and traffic management. In the 1980s, with the development of computers, microcosmic traffic flow simulation models were used in the study of traffic flow characteristics. Car-following model is a necessary basic component of microscopic traffic simulation model, and its research work has been paid attention to by people. In recent years, with the proposal and development of ITS (intelligent transportation system), car-following theory has once again become a research hotspot due to the need to understand the characteristics ...
