The Traffic Snake Game was created by Mobiel 21 and started as small campaign with only a handful of schools in Flanders, Belgium. 

Evidence had shown that the campaign successfully increases sustainable transport modes and reduces CO2. These days, the campaign reaches yearly around 1.000 schools, 200.000 children and 15.000 families in Flanders alone. The Netherlands and Austria were early adopters, but now no less than 18 countries are ready for their own flavour of this successful strategy that encourages parents to try alternatives to the car for home-school trips. The campaign is fun, effective and easy to implement.
