  • The faster you go, the more energy you need per distance.
  • The less efficient the energy conversion process is, the more energy you need to waste.
  • The more weight of the vehicle per passenger, the more energy you need.
  • The more friction/air resistance, the more energy you need (also dependent of the speed).
    • Economy: Tourism develops services related to the hotel, so more and more people can find jobs.
    Environment : Airplanes cause air pollution.
    Bus: LOW speed, HIGH waste, LOW weight per passenger, MEDIUM friction.

    Train: MEDIUM speed, LOW waste, HIGH weight per passenger, LOW friction.

    Airplane: HIGH speed, HIGH waste, MEDIUM weight per passenger, MEDIUM friction

    Social: Travelling unites different nations and cultures. 

    To sum up, Ben and his friends should go by bus or train although it causes more time!!!!!!!!!!!!!!!!!!!!!

That's why we are collecting the taxes for people wanting to enter the city center 
    Environment: we must limit the pollution due to transport. This is an ecological scandal.
    Social: The residents like not to waste too much time and avoid transport stress.
    To sum up, building new residential areas in the historic center reduces traffic jam without wasting too much money.
