Then, you will pick one problem of manageable size, and take action to solve it. First, think about the main ways people get around your community. If you're doing this as a class project, talk it over among yourselves. In many communities, the main way to get around is by car, on paved streets. In other places, people prefer pickup trucks to handle roads that are unpaved.
Cities usually have some public transportation, like a subway or bus system.
Kids too young to drive and people who like exercise may bike on bike paths or even skateboard to school or work. Again, if you are doing this as a class, talk it over. If you can't think of any problems, try calling your local newspaper and asking if they have done stories about traffic accidents at one particular place, complaints about unsafe roads, etc. Now that you have identified some problems, pick one to work on. It should be one you think is fixable, and also one that you and your class agree is worth an effort.
