城市中心区域小汽车停车设施选择模型

Selection Model of Car Parking Facility in Urban Central Region

为定量描述城市小汽车驾驶人停车设施选择行为影响因素,应用非集计理论,选取700份调查数据,分析了影响小汽车驾驶人选择的因素。将驾驶人个人属性、家庭属性、车辆属性与出行属性作为效用变量,选择收费停车场、免费停车场、违法停车区域3种停车设施作为驾驶人停车选择肢,构建了城市中心区域小汽车停车设施选择模型,并确定了模型中相应的变量及取值方法。另外选取185份调研数据,对模型精度进行验证。计算结果表明:应用本文模型,驾驶人选取收费停车场、免费停车场、违法停车区域3种停车设施计算结果比例分别为21.6%、45.4%与33.0%;计算值与统计值的绝对误差较小,最大仅为3.2%。可见,模型有效。

In order to describe the influencing factors of urban region quantitatively, based on the disaggregat parking facility selection behaviors for car drivers in e theory and 700 investigation sample data, the influencing factors of parking facility selection for car drivers were analyzed. Taking the individual attribute and family attribute of driver, vehicle attribute and travel attribute as utility variables, taking the parking facilities such as charge parking lot, free parking lot and illegal parking region as the alternative parking parts of car drivers, the selection model of car parking facility in urban central region was set up, and its corresponding variables and obtaining value method were determined. According to other 185 investigation sample data, the accuracy of the proposed model was verified. The calculation result shows that （ 1 ） by using the proposed model, the calculated proportions of charge parking lot, free parking lot and illegal parking region are 21.6% , 45.4% and 33.0% respectively; （2） the absolute errors between calculation values and statistical values are smaller, and the maximum error value is only 3.2%. Therefore, the model is effective.
