Transportation is a crucial infrastructure for the urban mobility and the urban systems. It comes in many forms how: streets, roads, walkways, bike paths, rivers, airports, and others. Transportation requires a good planning based on current datas plus future datas (through models simulating this cases). This infrastructure is reponsible for nivels of interaction between people and built environment. Every day, we need some modal in transportation ( private or public transportation, bicycle, trains, subway, on foot...). Transportation is an example of stocks and flows; it determines that stock can be moved from one plane to the next, creates a flow of people. So, this infrastructure need a constant maintenance and update because this traffic increases every day; but is also need to increase the use of transportation that produce less pollution (how bikes and public transportation) as an alternative to reducing pollutants in the city.
