The number of people owning their first car has increased significantly in developing countries. The principal problems this causes are pollution and traffic jam, and the most viable solution is to increase number of public transport and build LRT in city.
The primary issue developing countries face when their citizens start to buy cars is increased pollution. This occurs as a result of growing hazardous exhaust fumes from those private vehicles which ranks only behind the carbon emission from industrial activities. The greater number of personal means of transport on the road is also responsible for a rise in traffic jams. This is because the road system and infrastructure in low and middle-income countries have not kept up with the volume of traffic, especially in metropolis cities like Istanbul in Turkiye. Narrow streets, lack of parking lots and ineffective traffic system often result in long-hour traffic jams which make it a huge problem for most commuters. For example, during rush hours in Istanbul it may take from 30 minutes up to 50 minutes to travel a 500-meter distance.
A solution to these problems is to ban private cars in downtown areas while only allowing public transportation. This would solve the problems by discouraging current car owners from communting to work this way as well as making other people consider more carefully before purchasing their first car. Therefore, one solution could be make limit to cars in downtown areas like in Ulaanbaatar in Mongolia.
In conclusion, due to the growing number of first-time car buyers, the major problems that developing countries are facing are worsening air quality and persistent heavy traffic and limiting private cars in city areas is thought to be the most viable solution to this issue.
