摘　　要：Based on the impact of a desired following speed and safe distance on driving behaviour,we establish a cooperative car-following model(CCFM).The dynamics analysis results indicate that no unrealistic deceleration or collision occurs in the CCFM.Also,this model can describe the kinetic property in the processes of starting and braking.In addition,evolution of a small perturbation can be reproduced in a numerical simulation.Compared to the full velocity difference model(FVDM),the CCFM has a wider range of stability and a much smaller blocking region width.Meanwhile,the CCFM averts negative velocity,and is accordingly advanced compared with the comprehensive optimal velocity model(COVM).Moreover,the CCFM describes the deceleration process more smoothly than both the FVDM and COVM.
