Physical Routing Guidelines

Metro primarily operates three types of buses: a standard 40-foot bus, a 45-foot bus, and a 60-foot “articulated” bus. To ensure that buses can adequately navigate route alignments and serve bus stops, Metro established the following standards:

Transit Centers /Bus Terminals

Layover zones should be designed to accommodate various sizes of buses (40-foot, 45-foot, and 60-foot).

Re-striping of layover zones should be implemented on an as needed basis based on needs and size of buses scheduled.

Scheduled routes should be scheduled in such a way that the amount of layover space can be accommodated.

Minimum turning radius clearance required for each type size bus movement

  • 44 feet for both 40-foot and 60-foot articulated buses
  • 47.5 feet for 45-foot buses

Street Lane Widths for Bus

Street lane widths for bus operations must be 12 feet or more

Bus Stop Curb Lengths and Zone

  • 40-foot buses should at minimum be:
  • Farside – 90 feet
  • Nearside – 100 feet
  • Mid-block –150 feet

Note: For two 40-foot buses servicing a stop simultaneously, add 50 feet. Additional bus stop curb length may be needed for 45-foot buses.

  • 60-foot bus should at a minimum be:
  • Farside and mid-block – 120 feet
  • Nearside – 170 feet

Note: For two 60-foot buses servicing a stop simultaneously, add 70 feet.

Bus Layover Zone general space requirements for service operating on schedule:

  • One Space – 15 minutes
  • Two Spaces – 12 minutes
  • Four spaces – 6 minutes
