Platform Slope Maximum longitudinal slope for at-grade stations 1.75%
Maximum longitudinal slope for underground and aerial,stations 0.50%
Station cross slopes should be flat for safety,

but if required for improved drainage, slope away from platform edge at a maximum cross slope:

1.00%


Passenger

Circulation

Vertical Circulation Elements (VCEs),- Ramps, Stairs, Escalators and Elevators
1. Use of sloping walkways in lieu of ramps and ramps in lieu of elevators where feasible, is acceptable. Note:For a vertical rise less than 8’-0”, elevators and lifts shall be used only when unavoidable due to space constraints. Less than 12'-0"
2. Elevators are required for disabled access within the station for vertical rise greater 12’-0”. Stairs are required as well. 12'-0" to 16'-0"
3. Use paired escalators and stairs. Escalators,shall be the primary for ascent and stairs primary for descent. Note: Escalators may be replaced with primary passenger elevators if LOS analysis yields an average,wait time of 45 seconds or less using not less than 2.5 square feet,/passenger to determine capacity. 16'-0" to 20'-0"
4. Use elevators and escalators. Stairs shall not be considered a means of normal public ascent or descent where the vertical rise between levels exceeds 20’-0”. Note: Escalators may be replaced with primary passenger elevators if LOS analysis yields an average wait time of 45 seconds or less using not less than 2.5 square feet /passenger to determine capacity. Greater than 20'-0'
Vertical Clearance 1. Minimum headroom over primary stair or escalator measured perpendicularly from edge of tread nosing to underside of ceiling or overhead construction. 10'-0"
2. Minimum headroom at ceiling structures such as signage. 8'-6"
Elevators

Note: Elevators shall comply with APTA RT-RP-FS-007-02; ASME A17.1; ADAAG

1. Minimum queuing in front of elevator doors. 1.5 x Depth of Cab
2. Minimum overhead protection for elevator doors exposed to the outdoor with street level landings. 6'-0" Depth x Width of each cab
3. Where primary passenger elevators are required along a primary circulation route, minimum capacity required. 20 persons, 4500-pound capacity
4. All elevator cabs shall be sized to accommodate a 24”x84” ambulance stretcher in horizontal, open position. Provide ADA and gurney elevators in all locations where elevators are warranted. Min capacity of each cab. 16 persons, 4000-pound capacity
5. Minimum door sizes to accommodate wheelchairs, gurneys. 3'-6" wide x 7'-8" high
6. Minimum speed of elevators at passenger,carrying capacity. 200 fpm
Site Walkways Minimum width 5'-0"
Minimum vertical clearance 8'-0"
Pedestrian at-grade crossing minimum width 12'-0"
Through bus stop and Park & Rides 10'-0"
Crossing connecting walkways 10"-0"
Pedestrian tunnels 16'-0"
Walkway track crossing serving primary entrances 30'-0"
