Five "Old Rules of Thumb"

  1. We should have a high level of service
  2. Wider streets are safer
  3. "Enough" off-street parking for every use
  4. Car trips are generated by every land use
  5. Hierarchy of streets

Four "New Rules of Thumb"

  1. Closer is better
  2. Slower is safer
  3. Sharing is efficient
  4. Design for accessibility not mobility
