基于元胞自动机的绿色驾驶行为特征仿真

绿色驾驶是可以使驾驶人在驾驶过程中节油减排的一系列驾驶措施。为了研究绿色驾驶的行为特征，建立了多车道元胞自动机模型进行仿真，并以北京北三环某路段作为仿真场景对模型进行标定和验证。利用该仿真模型，研究纵向驾驶行为和横向驾驶行为对交通运行、能源消耗以及尾气排放产生的影响。构建了绿色驾驶行为判别标准，并通过预测得到绿色驾驶行为特征。研究发现，缓慢加速、保持车速稳定、将车速保持在合理区间以及保持较大的安全间距是符合中国道路特性的绿色驾驶行为。

Characteristics simulation of eco-driving behavior based on cellular automata

Eco-driving is a series of driving measures that can achieve the effect of fuel-efficiency improvement and emission reduction during the driving process. To study the behavioral characteristics of eco-driving, a multi-lane cellular automata model was established to simulate, and the data of a section of freeway in Beijing North Third Ring Road was used as a simulation scenario to calibrate and validate the model. Then, based on this computer simulation model, the effects of car-following driving behavior and lateral driving behavior on traffic operation, energy consumption and exhaust emission were revealed. The eco-driving behavior criterion was established and then, the eco-driving behavior characteristics were predicted. It is found that slow acceleration, maintaining the stability of the vehicle speed, keeping the vehicle speed at a reasonable interval and maintaining a large safety distance are the characteristics of eco-driving behaviors in line with Chinese road characteristics.
