Baghdad city suffer from the traffic jams problem. The lack of roads is accommodating the increase in transportation as well as the lack of the organization and healthy management. Meanwhile, traffic lights defect due to it may location near to the checkpoint which causes traffic jam and unusual delay. The transportation services depend on (private, taxi) cars which cause increase in traffic movement, energy consumption, emission of polluting gases for environment and the most important (first carbon oxide, nitrogen oxides, lead, carbon dioxide, suspended particles, oxides of sulfur. Thereby, this research will done determination the pollution rates induced from congestion in streets associated in the yard located near institute of technology / Baghdad. An account rate gases emitted from vehicles using regression equations de-pending on traffic size in streets, flow speed traffic movement, neighbouring building height, and afforestation density. The search reached to finding species and gasses rate which pollution the environment in comparison with international Health standards and benefit of the application Intelligent Transportation Systems (ITS) to reduce of the pollution ratio the resulting of traffic jams.

Iraq suffers from a housing problem, especially if it knows that there is a huge population deficit in Iraq estimated at more than 3 million housing units corresponding to a large variation in housing construction rates. Which led to the aggravation of the housing problem in the country. Therefore, it requires the responsible authorities to accelerate the adoption of a new strategy to solve the housing problem. The principle of establishing low cost residential complexes is based on adopting multi-storey residential buildings of 3 to 4 floors. The characteristic of these buildings in terms of suitable population densities, effective and economical use of the land. Thus, reducing housing costs to meet the large deficit and the growing population demand. For the target year 2040, the expected population of Baghdad will be increasing 11174249 people. So, the estimate of the housing need for the city of Baghdad 2040 need to 1196340 housing units. General, adoption of multi-storey housing (3-4) is the solution to eliminate the housing problem.
