What are the solutions to traffic congestion?

[DiCaroline]

Solutions to traffic congestion are as follows: Increase road capacity: This is the most fundamental method to solve traffic congestion, including widening existing roads or constructing new ones. As car usage increases, more roads are needed to accommodate the flow of vehicles. Reduce road intersections: This method includes elevated roads, underground roadways, and grade separation of existing railways. This is also a way to increase capacity. Restrict vehicle access: Some cities implement odd-even license plate policies, restricting access to vehicles with odd-numbered (odd) or even-numbered (even) license plates on specific days (e.g., Beijing, Hangzhou). Some cities also restrict access for certain vehicles, such as large trucks.
