Abstract: The increasing number and variety of bicycles, including regular bicycles, bicycle-style electric bicycles, and scooter-style electric bicycles have made heterogeneous bicycle traffic the dominant flow in China's bicycle lanes. To scientifically describe the evolution of heterogeneous bicycle platoons, the perceived density and pseudo-lane theory are incorporated into the cell transmission model (CTM) framework, based on an in-depth analysis of the operating characteristics of heterogeneous bicycle traffic flows on urban roads. As a result, a perceived density and pseudo-lane CTM (PPCTM) considering the characteristics of heterogeneous bicycle traffic flow is established. The validation results show that the PPCTM outperformed Robertson’s platoon dispersion model and the CTM in describing heterogeneous bicycle traffic state, reducing the average prediction mean square error by 32.38 % and 28.88 %, respectively. This research model contributes to understanding the evolution patterns of heterogeneous bicycle platoons and may inform for lane planning and signal timing optimization for heterogeneous bicycle environments.
