基于混合选择模型的图状路径信息板影响分析

有别于以往关于图状路径信息板(GRIP)影响的行为建模研究,运用混合选择模型研究了GRIP对驾驶员路径选择的影响。模型中通过恰当地构造"驾驶经验"和"GRIP信任度"两大潜变量,精细地刻画GRIP的影响机理。以上海实地存在的GRIP为研究对象,利用驾驶员行为调查数据,定量分析GRIP传递的事故和拥挤程度信息对路径选择的影响。分析结果表明,GRIP信息会显著影响路径选择,驾驶经验和GRIP信任度与提前驶离快速路的概率分别呈负向和正向关系,且驾驶经验的影响因个体属性而异。

Analysis on the Influence of Graphical Route Information Panel on Driver Route Choice Based on an ICLV Model

Unlike previous behavioral modeling studies on the influence of graphical route information panel (GRIP), an intergrated choice and latent variable model was used to explore the impact of GRIP on driver route choice. By properly constructing two latent variables, i.e. the driving experience and GRIP trust, the model can depict the influence of GRIP more precisely. Taking GRIP on the spot in Shanghai as the research object, the driver behavior survey data was used to quantitatively analyze the impact of the accident and congestion degree information transmitted by the GRID on route choice. The results show that the GRIP can significantly affect the probability of path selection. In addition, the driving experience has a negative relationship with the probability of leaving the expressway ahead, and the GRIP trust is positively related to the probability of leaving the expressway ahead. The influence of driving experience varies with individual attributes.
