摘要:AbstractTo improve the traffic operation and take advantage of the space resource, left-turn vehicles waiting area and straight vehicles waiting area are adopted separately at intersection at home and abroad, but there is not much research for using left-turn and straight waiting area together at the same intersection. Research using simulation software PARAMICS combining with programming API to simulate a specific comprehensive waiting area in Guangzhou city under nine different traffic volumes for three conditions: following control strategy, underutilizing control strategy and without control strategy. By evaluating the following four indexes: link delay, queue length, link average speed and passing vehicles, the simulation results indicate that the improving effect of following control strategy is superior to the underutilizing control strategy. Implementing comprehensive waiting area and in conjunction with the following control strategy can improve traffic operation when traffic volume is larger than the surveyed situation volume while the improvement is more effectively when traffic volume continues to increase. Setting comprehensive waiting area cannot improve intersection traffic operation but will worsen the traffic operation when traffic volume is less than the surveyed situation volume.
