N2  - An exploratory procedure for analyzing the permitted left-turn capacity with exclusive lanes is presented, including several empirical models for opposing queue length prediction, permitted saturation flow of mixed traffic, and effect of bay length on the left-turn capacity. Some critical factors, such as the number of opposing lanes and the interactions between upstream and downstream green time-cycle length ratios, have been incorporated in the proposed procedures for capacity estimation. A discrete choice modeling methodology has been applied to predict the fraction of time in a cycle during which the through queue length may be over a certain distance. Such a model enables traffic engineers to determine the left-turn bay length from a cost-benefit perspective. It should be noted that all proposed empirical models are grounded on the simulation experiments with TRAF-NETSIM. Hence, adjustments or modifications may be necessary after extensive field observations are conducted to calibrate TRAF-NETSIM.
