“…Guo et al [50] designed a double flow control protocol to ease traffic jams and reduce energy consumption. Peng et al [51] presented a lattice hydrodynamic model by considering the timid and aggressive driver's characteristics corresponding to the honk effect under the V2X environment for a two-lane highway, obtaining the associated stability criterion and mKdV equation. Notwithstanding that, as a next-generation transportation carrier, CAVs have high requirements on network bandwidth and communication timeliness.…”

In the presence of Vehicle-to-everything (V2X) communication technologies, connected automated vehicles (CAVs) can extend the drivers’ perception ranges and obtain more abundant road vehicle information to regulate the vehicle status in real time. Nevertheless, promoting CAVs is a long process, and there will be both artificially human-driven vehicles (HDVs) and CAVs on the road during this transition era. Besides, as one of the basic microscopic driving behaviors, overtaking is relatively rare in the traffic flow model, especially in mixed-traffic environments. To fill this gap, we propose a novel heterogeneous traffic flow accounting for the HDVs and CAVs with passing effects from a macroscopic perspective. Subsequently, we conduct the linear stability analysis to determine the stability norm corresponding to the new model. When the above stability criterion is not established, we investigate the nonlinear phenomenon of the proposed model, and the modified Korteweg-de Vries (mKdV) equation and its existing conditions are obtained separately. When the overtaking ratio is adequately low such that the existence condition is met, the entire phase space consists of two parts, no jam and kink jam; when the passing ratio surpasses the threshold and the existence condition is not satisfied, the original unstable region can be further subdivided into kink jam sub-region and chaotic sub-region, and the density wave gradually evolved from kink-Bando traffic wave into the chaotic phase with the increasing of penetration rate. The results of the numerical examples verify the theoretical derivation.

This paper focuses on traffic scenarios randomly mixed with cooperative adaptive cruise control (CACC) vehicles and manual vehicles with vehicle-to-vehicle (V2V) communication. The analytical investigation of string stability of such mixed traffic flow is conducted under different CACC penetration rates. The parametric sensitivity analysis on CACC desired time-gap is also studied. Moreover, numerical simulation is conducted under both open and periodic boundary conditions. Research results indicate that increase of CACC vehicles is helpful for improving the mixed traffic flow string stability. The mixed flow will be stable for all possible velocities if CACC rate reaches to 0.64 when the CACC time-gap is considered as 0.6s. Larger CACC time-gap would have more stable regions in string stability charts with respect to equilibrium velocity and CACC penetration rate. This paper contributes to a new way for analytical investigation of string stability of the mixed CACC traffic flow.
