ELI5: Explain Like I'm 5

Mode choice

Mode choice is like choosing how to get from one place to another. It's like deciding if you want to walk, ride a bike, take the bus, or drive a car.

Now imagine that you're going to the park to play. You could walk there, but it might take a long time and you might get tired. You could ride a bike, but you might need help from an adult to balance and steer. You could take the bus, but it might be crowded and noisy. Or you could get in a car and drive there, but you would need an adult who knows how to drive and a car to use.

Each of these ways of getting to the park is called a "mode". People choose which mode to use based on lots of different things, like how far away the park is, if they have a car, if it's raining or sunny outside, if they want to exercise along the way, and many other reasons.

So, mode choice is just a fancy way of talking about how people decide how to get from one place to another. It's like making a decision about which toy to play with or which snack to eat – it depends on what you feel like doing and what options are available to you.
