考虑共享停车的用户出行选择研究

Research on Travel Choices of Users Considering Shared Parking

为探讨共享停车的出现对用户出行选择的影响,将出行者划分为共享停车和普通停车两种用户类型,分别构建停车阻抗函数,并基于分层Logit (NL)建立停车和路径联合选择结构模型。进一步提出带有两种停车方式的随机用户均衡模型,并改进相继平均算法对模型进行求解,通过算例分析发现预约费用从4元变化到12元时,共享停车需求量从378辆下降到320辆,普通停车需求量从222辆上升到280辆,而步行时间从0.05 h变化到0.1 h时,共享停车需求量和普通停车需求量基本保持不变,分析还发现了考虑NL模型构建的随机用户均衡模型比不考虑NL模型更加符合实际的交通路网出行。

In order to explore the impact of shared parking on user travel choices,the travelers were divided into two groups,i.e.the shared parking users and traditional parking users.The parking impedance function was constructed respectively for the two groups.The structural model for route and parking joint selection was established based on nested logit(NL).A stochastic user equilibrium model with two parking modes was proposed and solved by using the improved method of successive averages.The results show that when the reservation fee increases from 4 yuan to 12 yuan,the shared parking demand decreases from 378 vehicles to320 vehicles,while the demand for ordinary parking increases from 222 vehicles to 280 vehicles.When the walking time rises from 0.05 h to 0.1 h,the shared parking demand and ordinary parking demand remain unchanged.It is also found that the stochastic user equilibrium model with NL is more suitable for the actual traffic network than that without NL.
