A. Yield. Drivers must proceed slowly, with extreme care, and must yield to approaching traffic when vehicles are parked on both sides of the thoroughfare creating essentially one through lane. A Yield Thoroughfare is the functional equivalent of traffic calming. In addition to Yield movement use on normal thoroughfares, this movement is used for Alleys and Rear Lanes. For these applications, the primary purpose is access to rear loaded driveways/access for residential and commercial property. The 12' travel lane for Rear Lanes can be configured for one-way or two-way operation. When used for two way travel, parking is required on both sides of street in order to facilitate the Yield Movement Type and drivers exiting garages or driveways will have to yield to those vehicles occupying the lane therefore the number of properties connected to the Rear Lane should be considered. Parking in Alleys and Rear Lanes should only occur in driveways or parking structures to allow access for trash collection, service trucks and emergency access. Design speed is less than 20 mph.

B. Slow. Drivers can proceed carefully with an occasional stop to allow a pedestrian to cross or another car to park. The character of the thoroughfare should make drivers uncomfortable exceeding the design speed due to the presence of parked cars, sense of enclosure from buildings and street trees, tight turning radii, and other design elements. Design speed is 25 mph.

C. Low. Drivers can generally expect to travel without delay at the appropriate design speed. Thoroughfare design supports safe pedestrian movement at the higher design speed. This movement type is appropriate for thoroughfares designed to traverse longer distances or connect to higher intensity locations. Design speed is 30-35 mph.

D. Suburban. This is a conventional thoroughfare design in which drivers can expect a separation of modes, (i.e., bike lanes, walking paths and roads) allowing automobiles to travel unimpeded by pedestrians or walkability concerns. This movement type is rarely used in T3 through T6 transect zones, but may be needed when a thoroughfare crosses through T1 or T2 transect zones. Design speed may be above 35 mph.

The design criteria for Yield, Slow, and Low Thoroughfares shall be commensurate with local thoroughfares. Design speeds higher than 35 mph shall not be used in areas intended to support moderate or high levels of pedestrian or bicycle activity due to concerns with safety and comfort.
