Solution

This might seem counterintuitive, but it can happen due to a few reasons:

  1. Braess's Paradox: This is a concept in game theory where adding extra capacity to a network, such as roads in a city, can actually reduce overall performance. When there are fewer cars, drivers may choose the most direct route without causing a bottleneck. But when more roads are added, drivers may still choose the most direct route, causing congestion.

  2. Induced Demand: This is the idea that increasing supply creates its own demand. So, when there are fewer cars, there's less demand for road space. But when the number of roads increases, it can encourage more people to drive, thus creating more traffic.

  3. Inefficient Use of Space: Cars take up a lot of space for only one or a few individuals. When there are fewer cars, more space is available for other modes of transportation like biking, walking, or public transit, which can move people more efficiently.

  4. Poor Public Transportation: If a city has poor public transportation, people are forced to rely on cars for commuting. Even if there are fewer cars, the lack of a good public transportation system can lead to traffic congestion.

  5. Inadequate City Planning: Sometimes, the city's infrastructure might not be designed to handle a large number of cars. Narrow roads, lack of parking spaces, and poor traffic management can lead to congestion even when there are fewer cars.

So, it's not just about the number of cars, but also about how efficiently the city's transportation system is designed and managed.
