Simulation research of traffic capacity of weaving section on urban expressway

As an important part of the highway, the weaving section undertakes the merging and the diverging of the traffic flow, which is an important traffic bottleneck that deserves to be studied.1 This paper focuses on analyzing and evaluating the traffic capacity of this bottleneck. The vehicle trajectory dataset chosen for this study originates from the Next Generation Simulation (NGSIM) initiative conducted by the Federal Highway Administration (FHWA). The study area spanned roughly 640 meters in length and comprised of five primary lanes throughout the section, as. Additionally, an auxiliary lane was present along a portion of the corridor, running between the on-ramp at Ventura Boulevard and the off-ramp at Cahuenga Boulevard. The parameters for evaluation are capacity, average queue length, average delay, average time in the queue, and average excess accumulation. To improve the traffic, some strategies will be given. VISSIM simulation is used to see the effectiveness of these solutions.
