Traffic jam, also known as traffic congestion, is a major problem in many cities around the world. It occurs when the number of vehicles on the road exceeds the capacity of the road system, causing traffic to slow down or come to a complete halt. Traffic jams can cause a lot of frustration for drivers and passengers, as well as have negative impacts on the environment and the economy. In addition to being a waste of time and fuel, traffic jam also contribute to air pollution and greenhouse gas emissions. To help address the problem of traffic congestion, governments and transportation authorities have implemented a range of solutions, including expanding public transportation systems, creating carpooling and ride-sharing programs, and implementing congestion pricing to discourage single-occupancy vehicle use during peak hours. While these solutions have had some success in reducing traffic congestion, it remains a persistent issue in many cities, and more action is needed to create sustainable and efficient transportation systems that can reduce traffic congestion and improve the quality of life for people who live and work in urban areas.
