What is the primary benefit of using light rail compared to personal vehicles?

The primary benefit of using light rail compared to personal vehicles is the reduced traffic congestion and environmental impact. Light rail systems can transport a large number of passengers simultaneously, significantly decreasing the number of individual cars on the road. This reduction in vehicle use leads to less congestion on roadways, making travel more efficient for everyone. Additionally, light rail often uses electric trains, which can lead to lower emissions compared to gasoline-powered personal vehicles, thus contributing to a cleaner environment.

While lower ticket prices and faster travel times may appeal to some riders, the overarching impact of light rail on urban mobility and environmental sustainability is a more substantial advantage. Access to entertainment options on board is more of a side benefit and does not directly relate to the primary reasons for light rail's advantages over personal vehicles.
