Okay kiddo, so imagine that you're a big grown-up who works for the city. One of the things you need to do is figure out how people get around the city. You need to know if they walk, bike, take the bus, or drive a car.
To do this, you ask a bunch of people to fill out a survey about their travel habits. They tell you information about where they live, where they work or go to school, and how they get there.
Now, every time you do this survey, you collect a lot of information! So much that you can't keep it all in one place. That's where the metropolitan travel survey archive comes in. It's like a big library where you can store all the survey results from different years and cities.
This archive is really useful because it helps the city planners learn about how people move around the city over time. They can see if more people are using public transportation, or if more people are driving cars. This information helps them make decisions about how to design the streets and what kind of transportation options to offer.
So, in short, the metropolitan travel survey archive is like a big library full of information about how people travel in different cities. By looking at this information, the city can make better decisions about transportation.
