| 摘要： | The study investigates the application of simulation along with field observations for estimation of exclusive left-turn saturation flow rate and capacity. The entire research has covered the following principal subjects: (1) A saturation flow model for protected phase that allows engineers to incorporate local-specific driving behavior in the analysis; (2) A permitted saturation flow model that accounts for the impact of driving behavior and traffic conditions at both the target and the opposing upstream intersections on the permitted saturation flow rate; (3) A queue length model for estimation of the resulting queue length under various phase schemes; and (4) A hybrid bay length impact model that provides engineers a convenient tool to assess the impact of various bay lengths on the left-turn capacity at both isolated and coordinated intersections. This report also describes the procedures for direct estimation of intersection capacity with simulation, including a set of rigorous statistical tests for simulation parameter calibration from field data. |
