项目摘要

This study aims to establish a method of estimating the demand of parking spaces for loading and unloading by delivery vehicles in CBD and of developing and evaluating their location plans. The main findings of the study are the followings :(1)First, we chose four areas of CBD in our study and conducted surveys in the four areas to reveal inflow and outflow of goods in business establishments and actual situation of loading and unloading activities by delivery vehicles.(2)We proposed the method of estimating the demand of parking spaces by using the next equation. P=Σ__i(F_i×U_i)×C×T/RP : Demand of parking spaces for loading and unloading (unit : vehicle)F_i : Floor space of business type i (m^2)U_i : The number of parcels handled in business type i (number/m^2)C : The number of vehicles needed for delivering per parcel (vehicle/number)T : Peak ratio of delivery vehicles of the dayR : Turnover of vehicle (number/hour)(3)The demand estimation could be obtain through calculating the above indices in the equation which come from the surveys. We estimated the number of delivery vehicles in survey areas by using the indices and verified the compatibility of the estimation results to actual number of delivery vehicles observed.(4)On the basis of the estimated demand of parking spaces, we proposed the method of developing their location plans by using P-median problem and P-center Problem, and also of evaluating them from viewpoints of improving the efficiency in loading and unloading activities, and reducing the quantity of illegally parked cars. Finally, we applied the method in the study areas and verified its usefulness.

本研究旨在建立一种方法来估算中央商务区的运输车辆装卸停车位的需求，并制定和评估其位置规划。研究的主要结果如下：（1）首先，我们选择了CBD的四个地区进行调查，以了解商业机构的货物进出情况和送货车辆上落货活动的实际情况。(2)We提出了利用下式估算停车位需求的方法。P= F_i（F_i×U_i）×C×T/RP：装卸车位需求（单位：辆）F_i：业务类型i的占地面积（m^2）U_i：业务类型i处理的包裹数量（个/m^2）C：每个包裹运送所需的车辆数量（车/辆）T：当日送货车辆高峰率R：车辆周转量（辆/小时）（3）通过计算调查得出的方程中的上述指标，可以得到需求估计。利用该指标对调查区域的运输车辆数量进行了估计，并验证了估计结果与实际观测到的运输车辆数量的相容性。(4)On摘要在对停车位需求进行预测的基础上，提出了利用P-中值问题和P-中心问题制定停车位选址方案的方法，并从提高装卸效率和减少违章停放汽车数量的角度对停车位进行评价。最后，将该方法应用于研究区，验证了其有效性。
