In practice, traffic calming takes many forms. It can include very simple measures such as planting trees or installing signs. More sophisticated traffic calming projects have introduced physical measures that force motorists to slow down.

Such physical measures can be very successful when complemented with police enforcement and educational outreach. All measures in the end have the same purpose, which is to make the streets safer and more livable, and to reduce unsafe driving.
