In many areas of Baghdad, the capital of Iraq, there has been an unplanned and random shift in urban land use where a significant portion of the residential land within the city has been converted to commercial uses. This alteration in land use has led to severe traffic congestion due to the influx of vehicles frequenting these areas, the streets' insufficient capacity to handle the vehicular traffic, and a lack of adequate parking spaces. The research aims to develop a statistical model to calculate the needed parking spaces in Baghdad's commercial areas. It is estimated that the required vehicle parking can be determined by the areas of the buildings. The research concludes that certain commercial activities, such as restaurants and stores, necessitate more vehicle parking compared to other commercial activities, and the demand for parking spaces is directly proportional to the commercial activities' area.
