Imagine you are taking a trip on two types of cars, one that drives on the highway and another that drives on the streets. Dual-mode buses work the same way. These buses can drive on the regular streets or highways using wheels, but they can also go on special tracks (like a train) using rubber wheels or a rail, depending on the type of tracks.
Dual-mode buses can switch between the two modes of transportation, so they can drive on the streets and transfer to the tracks when it's necessary. This is beneficial because the buses can avoid congestion on the regular streets, and they can move quickly and efficiently on the tracks.
It's like having two modes of transportation in one vehicle, just like if you were able to transform your car into a train on a special set of tracks. This new mode of transportation can help people get to their destination quickly and conveniently.
