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:
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.
- 44 feet for both 40-foot and 60-foot articulated buses
- 47.5 feet for 45-foot buses
Street lane widths for bus operations must be 12 feet or more
- 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
