The World’s Most Traffic-Congested Cities with the Busiest Streets

According to SAEDNEWS, Due to population growth and the complexity of social and economic changes, concepts such as traffic congestion and population density have become new challenges for cities. In this context, some cities have been recognized as the most traffic-congested areas in the world. Heavy traffic in these cities has not only become a social challenge but also a benchmark for measuring complexity and urban management strategies in urbanization.

In this section, we will examine the most traffic-congested cities in the world. From cities where traffic has become a serious problem to the experiences and solutions adopted to manage and control traffic in these areas. Of course, urban traffic may depend on various changes, and the list below shows cities based on their severe traffic conditions. Interestingly, despite Tehran’s heavy traffic, the capital of our country is not included in this list.
