Evolutionary Game Mechanism of Free Lane Changing for Vehicles with Different Driving Styles
To study the evolutionary game mechanism of lane changing and target lane following vehicles with differ-ent driving styles.Extract lane changing trajectory data of vehicles on fast road sections in Suzhou city,and cluster driv-ing styles using K-means algorithm.By quantifying the profit parameters and weight coefficients of vehicles with different styles,an evolutionary dynamic equation is constructed.The stability of the equilibrium solution of the evolutionary game is analyzed based on the determinant and trajectory of the Jacobian matrix.The evolution path of lane changing decisions is simulated numerically,and sensitivity analysis is performed on different profit parameters.The results indicate that the stable strategy combination of the evolutionary game is(changing lanes,giving way)and(not changing lanes,not giving way).When in the same initial state,the aggressive lane changing vehicle converges the fastest to a stable strategy when interacting with the cautious rear vehicle.The most significant inhibition of stable strategy evolution towards(lane chan-ging,yielding)is the increase in demand returns over time.
