基于结构方程模型的共享停车选择行为研究

Choice Behavior of Shared Parking Based on Structural Equation Model

共享停车对解决城市交通停车难题有重要意义。为分析城市共享停车用户选择行为的影响因素,构建了基于混合的多项选择模型。该模型上层通过引入感知风险、知识水平和服务质量这3个潜变量扩展了技术接受度模型;利用结构方程模型分析各潜变量间的结构关系和路径显著性,验证了模型提出的假设,将上层估计的潜变量和社会属性变量带入下层多项Logit模型并对模型参数进行标定。研究结果显示:停车用户潜变量、个人及家庭属性和停车特征均对用户选择共享停车具有显著性影响;相较路边停车,共享停车无论是服务质量还是安全性均对用户吸引力更大,但是跟专业化运营的公共停车场相比优势不够明显。

Shared parking is of great significance in solving the problem of urban traffic parking.To analyze the factors influencing the choice behavior of urban shared parking users,a hybrid-based multinomial choice model was constructed.The upper layer of the proposed model extended the technology acceptance model by introducing three latent variables such as the perceived risk,knowledge level and service quality.The structural equation model was used to analyze the structural relationship and path significance between each latent variable and verify the hypotheses proposed by the model.The latent variables and social attribute variables estimated by the upper level were brought into the lower-level multinomial Logit model and the model parameters were also calibrated.The research results show that the latent variables of parking users,the personal and household attributes and the parking characteristics all have significant influence on users'choice of shared parking.Compared to roadside parking,shared parking is more attractive to users in terms of service quality and safety,but its advantages are not obvious compared to the specialized public parking lots.
