Parking is  a major  concern in business districts  such as  Baghdad, one of the world's  largest  and most  populous  cities. The purpose of  this  study is  to examine parking lots  to identify issues  and provide an overall solution. The study includes  a survey of two parking lots, the Dream City Mall Lot  and the University of Technology lot  to gather  information and incorporate  the results  into Vissim, a microscopic simulation. Data  inputs  are Traffic  data,  Data  about the park to be studied, and data  about the efficiency of the park. Results  for  Dream City Lot  indicate  that  delays  on gates are up to 6.5 minutes and queue length is 18 cars  in the queue because of  congestion and high traffic  volumes.  The lot has  about 45% empty spaces  at  5 pm which is  a positive indication. For the University of  Technology Lot, The park was  over utilized, with cars  parked where they weren't  meant  to. There is  an issue with the low turnover  rate because university employees  use the parking lot  from early in the morning until 2:00 pm and parking spaces  cannot  be used by another vehicle. The research suggests  solutions  to improve parking for  each parking lot.
