ABSTRACT

Poor lane keeping behaviors may cause problems and ‘Level’ of lane keeping has received little attention from the researchers to gain a better understanding on degree of untidiness. Unfortunately, previous studies have not clarified the drivers’ lane keeping levels. For this reason, ‘level of untidy’ should be defined and the question of ‘in which level’ needs to be answered. Paper suggests five levels for quantitative measure of (un)tidiness so that the effects can be assessed for traffic flow models. For this aim, proposed levels are analyzed by considering road, vehicle, and traffic properties in urban roads. An ordered probit regression analysis was performed to investigate relation between keeping level and effective parameters using each vehicle's lateral position data. Results showed that volume and lane width parameters have a positive effect, and vehicle width and lane number variables have negative effect on keeping level as continuous variables of the model.

摘要

不良的行车行为可能会导致问题，研究人员很少关注行车道的“水平”以更好地了解不整洁度。不幸的是，先前的研究并未阐明驾驶员的车道保持水平。因此，应该定义“不整齐的级别”，并且需要回答“在哪个级别”。论文建议对（不）整洁度进行定量测量的五个级别，以便可以对交通流模型进行评估。为此，通过考虑城市道路的道路，车辆和交通特性来分析建议的等级。使用每辆车的横向位置数据进行有序的概率回归分析以研究保持水平和有效参数之间的关系。
