Abstract: Based on the characteristics and regularity of driver parking behavior, BL model in the theory of disaggregation was used to separately establish the selective model of public parking lots in weekdays and holidays with the characteristic variants, including parking lots pattern, parking fees, parking purpose and walking distance. The study on the overall rule of the drivers’ parking behavior in the public parking lots and the common rule of city selected was carried out. Taking the parking fee and walking distance as hypothetical variant, the improved BL parking behavior model was established to study the threshold of the preferential rates for the exchange of walking distance in the weekdays and holidays. The results show that: the purpose of parking is relatively centralized in weekdays and drivers whose purpose is commuting is more sensitive to parking fee and more inclined to choose public parking lots; the purpose of parking is relatively dispersive in holidays and the effect of the parking preferential measures on the parking lot choice of drivers reduces. Therefore, the difference of schemes between weekdays and holidays should be considered in improving the utilization rate of off-street public parking lots through favorable measures of parking fees.

摘要： 在探讨驾驶人停车行为特征规律的基础上，采用非集计理论中的BL模型以停车场类型、停车费用、停车目的、步行距离为特性变量分别建立平日、节假日公共停车场选择模型，研究公共停车场驾驶人停车行为的总体规律及所选城市的一般性规律；以停车费用及步行距离作为假设变量，建立改进的BL停车行为模型，研究平日、节假日优惠费率交换步行距离的阈值。研究结果表明：平日公共停车场停车目的相对集中，以通勤为目的驾驶人对停车费用较敏感且更倾向于选择公共停车场；节假日停车目的较为离散，停车费优惠措施对驾驶人停车场选择影响降低，因此，通过停车费优惠措施提高路外公共停车场利用率需考虑平日与节假日相区别的政策性方案。
