This study examined the transition from Traditional Vehicles (TVs) to Autonomous Vehicles (AVs) using microsimulation modelling approaches. For this purpose, the study first optimised the parameters of human driving behaviours to find out what would happen if AVs could drive with modified human behaviours. Then, the study acquired the optimised driving behaviours to evaluate how efficient AVs can be within the context of the anticipated driving behaviours. The shared road of AVs and TVs was tested for where the proportion of the AVs incremented by 10% from an entirely traditional network to a network fully occupied by AVs. Such an assessment of the shared road represented the transition periods between TVs and AVs in highway transport. Overall, the simulation results in this study indicated that AVs could substantially improve the quality of traffic, especially by reducing the number of stops, queue length, and delay time. The study also found that TVs and AVs can efficiently share their road, and the improvement in the quality of traffic increases with an increase in the proportion of AVs to TVs, up to a specific level, on the road. In this regard, according to the results from the peak and normal traffic conditions, a road with a 60% share of AVs can see its traffic quality improved as much as a road entirely populated by AVs. Therefore, dedicating 100% of the road traffic to AVs or devoting a dedicated lane for AVs in peak traffic hours might be as efficient as a shared road with 60% AVs.

模拟向自动驾驶的过渡

这项研究使用微观模拟建模方法研究了从传统车辆(TV)到自动驾驶车辆(AV)的过渡。为此,研究首先优化了人类驾驶行为的参数,以找出如果自动驾驶汽车能够以改变的人类行为驾驶会发生什么。然后,该研究获得了优化的驾驶行为,以评估在预期驾驶行为的背景下AV的效率如何。测试了AV和TV的共享路径,即从完全传统的网络到AV完全占据的网络,AV的比例增加了10%。对共享道路的这种评估代表了公路运输中电视和自动驾驶汽车之间的过渡期。总体,这项研究中的模拟结果表明,自动驾驶可以大大提高交通质量,特别是通过减少停车次数,排队长度和延迟时间。该研究还发现,电视和AV可以有效地共享道路,并且随着道路上AV到TV的比例增加到特定水平,交通质量的改善也随之增加。在这方面,根据高峰和正常交通状况的结果,拥有AV份额60%的道路可以看到其交通质量与完全由AV填充的道路一样多。因此,在交通高峰时段将100%的道路交通专用于AV或为AV使用专用车道可能与60%的AV共享道路一样有效。该研究还发现,电视和AV可以有效地共享道路,并且随着道路上AV到TV的比例增加到特定水平,交通质量的改善也随之增加。在这方面,根据高峰和正常交通状况的结果,拥有AV份额60%的道路可以看到其交通质量与完全由AV填充的道路一样多。因此,在交通高峰时段将100%的道路交通专用于AV或为AV使用专用车道可能与拥有60%AV的共享道路一样有效。该研究还发现,电视和AV可以有效地共享道路,并且随着道路上AV到TV的比例增加到特定水平,交通质量的改善也随之增加。在这方面,根据高峰和正常交通状况的结果,拥有AV份额60%的道路可以看到其交通质量与完全由AV填充的道路一样多。因此,在交通高峰时段将100%的道路交通专用于AV或为AV使用专用车道可能与拥有60%AV的共享道路一样有效。拥有60%AV的道路可以看到其交通质量与完全由AV填充的道路一样多。因此,在交通高峰时段将100%的道路交通专用于AV或为AV使用专用车道可能与拥有60%AV的共享道路一样有效。拥有60%AV的道路可以看到其交通质量与完全由AV填充的道路一样多。因此,在交通高峰时段将100%的道路交通专用于AV或为AV使用专用车道可能与拥有60%AV的共享道路一样有效。
