Abstract
The parking problem is a severe challenge in city planning because of its impact on road congestion and accidents, delay time, and cities’ economy. therefore, many cities conducted different studies, reports, and projects to find the number of parking generation as it related to land use, in form equations, rates, and even data plots by using different independent variables. Iraq, till now, does not have a comprehensive study of parking requirements, or in specific how many parking spaces the different land uses are generated or needed. The general situation in Baghdad city at present is inadequate public transportation, few transportation alternatives, large private car use. besides the high illegal parking on the roads which means higher traffic density and congestion roads. this research studies three different shopping centers in Baghdad and analysis their parking generation as related to three different independent variables. these variables are GFA, GLA, and entertainment percentage where each variable is analyzed separately. the analysis was done based on parking accumulation in these sites. as it was counted manually for three days for Parking counting time that selected according to the peak of visitors for Retail is from 4 pm – 11 pm. in a result several parking generation rates and models with different forms are developed by using simple linear regression and only the best of them that has high R2 value and low RMSE is recommended. from the conclusion, the GFA and GLA have the most significant effect on parking generation as they developed strong models and rates. as these rates are 4.1 and 4.57 parking spaces for each 100 m2 of GFA and GLA respectively.
