Abstract
Exploring queuing behavior of different types of lanes at signalized intersections is helpful for establishing the methodology for capacity analysis of each lane or group of lanes. In Taiwan's latest revised HCM, straight lanes and un-opposed left-turn lanes at signalized intersections were respectively divided into six types and four types in officially. The field data showed that queue discharge characteristics varied with the lane type and the location of the city, and the nonlinear regression models could accurately describe the discharge behavior of each lane type. Based on these regression models, the influence of the city location factor, fz, could be used to adjust the queue discharge behaviors among different cities. Therefore, this study collected queue discharge data in several Taiwan cities, performed statistical analyses, and compared the field data to determine fz. This study found that fz is an important parameter for comparing queue discharge behavior among cities.
