This study seeks to measure the mixed used of urban land for commercial and residential purpose in the large cities of Pakistan by using the indices of measurement for mixed use of land. The primary aim of this study is to analyze the impact of mixed use of urban land for commercial and residential purpose on reduction in commuting and congestion cost. This study also review and compare all the indices use in previous research by using Spearman’s correlation. The results suggest that most of the cities in Pakistan are not using urban land efficiently. Our survey results also show that there is significant reduction in commuting and congestion cost due to mixed use of urban land for commercial and residential purpose. Supervisor:- Dr. Zahid Asghar
