Two key principles drive Vital Street design in Grand Rapids:

1. All streets should be safe for all users

2. Streets should be logical and intuitive to use.

The design of a street shapes how people use it. How people operate on the street affects how safe a street is. Vital Streets must be designed to be self-regulating. Self-regulating design is street design that provides environmental cues to street users to enable them to naturally and intuitively comply with speed and other operating expectations thus improving safety.

Several factors must be considered in order to deliver self-regulating/self-enforcing streets:

• Vehicle Speed and Safety Outcomes

• Design and Control Vehicles

• Measures of Street Operation
