Spatiotemporal trajectory characteristic analysis for traffic state transition prediction near expressway merge bottleneck
Transportation Research Part C: Emerging Technologies(2020)
摘要
•The macroscopic and microscopic characteristics of traffic flow in congestion evolution near expressway bottleneck were captured.•The impact of lane-changing behavior on the formation and propagation of oscillation was quantified.•Inducement for triggering traffic phase transition was investigated.•Investigation on the critical headway of engendering perturbation.•Fluctuation magnitude of speed and the theoretical lag distance.
