Impact of lane changing on adjacent vehicles considering multi-vehicle interaction in mixed traffic flow: A velocity estimating model

Abstract

To quantitatively analyse the influence of lane changing vehicles on the speed of adjacent vehicles during the lane changing process, this paper designed a fleet lane changing experiment based on P3-DT Beidou high-precision positioning and direction finding receiver. The concept of cellular vehicle neighbourhood is proposed to quantitatively describe the influence of vehicle spacing on vehicle speed. A study into the speed changing model of adjacent vehicles during lane changing is performed. A simulation program is developed, and simulation results are compared with the measured data. The goodness of fit of the velocity change extent of adjacent vehicles in the target lane is over 80%, which validates the velocity estimating model. This model can provide a theoretical basis for research and development in the interactive simulation of multiple vehicles and automatic driving technology in mixed traffic flow.
