Summary
This study addresses the lack of comprehensive parking requirement data in Iraq, specifically focusing on shopping centers in Baghdad. The rapid increase in private vehicle ownership and the construction of new malls without adequate transportation planning have led to severe traffic congestion, illegal parking, and insufficient parking supply. The research aims to develop local parking generation rates and models based on specific land-use characteristics, rather than relying on arbitrary estimates or foreign standards that may not reflect local conditions. The methodology involved field surveys of three selected shopping centers in Baghdad: Zayoona Mall, Al-Nakheel Mall, and Baghdad Mall. These sites were chosen based on criteria such as maturity, occupancy rates, and the presence of defined parking areas. Data collection occurred over three days during the peak evening period (4 pm to 11 pm), which was identified as the time of maximum parking accumulation. The study analyzed parking demand against three independent variables: Gross Floor Area (GFA), Gross Leasable Area (GLA), and Entertainment Percentage (E%). Parking counts included both on-site and adjacent street parking to capture total demand. Simple linear regression was used to develop various model forms (linear, logarithmic, power, and exponential) for each variable. The results indicate that GFA and GLA are the most significant predictors of parking generation, producing strong models with high R² values (0.99) and low Root Mean Square Error (RMSE). In contrast, models based on Entertainment Percentage showed weaker predictive power and were not recommended for use. The study recommends specific parking generation rates derived from the best-fitting models: 4.1 parking spaces per 100 m² of GFA and 4.57 parking spaces per 100 m² of GLA. The analysis also revealed that parking demand peaks between 6:30 pm and 9:00 pm, with significant spillover onto adjacent streets for some malls, particularly Zayoona and Baghdad Malls. The significance of this research lies in providing the first localized parking generation models for Iraqi shopping centers, addressing a critical gap in urban planning data. By establishing evidence-based rates, the study offers decision-makers and municipalities reliable tools for planning parking infrastructure, thereby mitigating traffic congestion and optimizing land use. The findings emphasize the importance of using local data over international manuals, as local factors such as transportation modes and mall design significantly influence parking demand. This work serves as a foundational reference for future transportation planning and regulatory development in Iraq.
