Route2school helps schools and cities to make a very good analysis of the traffic safety on routes to school and the travel behavior of students. In this process the involvement of students is very important. We give the students the opportunity to tell us where and which kind of mobility problems they experience when they go to school, but we also want to know which kind of solution they suggest. These data are very interesting, because students experience traffic in another way as adults do. All these data will be collected by a mobile or web application.
