places connected by these roads. Street maps are like road maps but show a much smaller area, such as a single town or city. They also show all the streets, not just the main ones.
People also use other mobility maps to get from one place to another. Transit maps may show the routes traveled by buses, for example, stop to pick up and let out people. Special maps, called charts, are used to guide ships, boats, and airplanes. Some airplanes also have computer systems that can make maps.
