INTRODUCTION
Karachi is the most populated city of Pakistan with an estimated population of 22 million. It is the financial and economic hub of the country and many businesses are headquartered there. The city has a labor supply of almost 5 million people and a literacy rate of 83% on average. Karachi contributes approximately 25% - 30% to the overall GDP of the country and handles 60% of the nation’s cargo making it one of South Asia’s largest and busiest deep-water seaports.
Road and transport infrastructure in Karachi has remained neglected mostly because of a lack of investment in improving the road structure and developing public transport systems. More recently the issue has come under scrutiny with the provincial government looking to develop mass transit projects to tackle the issue of congestion and pollution by making public transport more accessible.
