| Research Abstract |
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/R
P : 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 day
R : 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.
