METRO RAIL DESIGN CRITERIA SECTION 9 / SYSTEMS

DE304.09 9-19 Revision 4: 05/09/12

Metro Baseline Re-Baseline: 04/29/10

- 30-55 seconds – Noticeable queues

- Greater than 55 seconds – Significant queues

The quantity of fare gates recommended shall be based on maintaining the

maximum queuing times below a 55 second service standard during the worst

case scenario (3 seconds per person per fare gate).

2. Exit Calculations:

Exit Calculations shall be performed for Metro Rail stations to evaluate impact of

fare barriers on station egress. Exit calculations for station shall be performed in

accordance with current edition of NFPA 130, Standard for Fixed Guideway

Transit and Passenger Rail Systems, to determine results of 4 minute tests, 6

minute tests, and waiting times at fare barriers for station egress specified

within.

 Calculations shall be based upon use of 10 year ridership projections and

Maximum Line Capacity as furnished by Metro Operations.

 Ridership projections shall be used to derive maximum hourly entraining

loads in both peak and off-peak directions, which based on surge factor and

headway, shall be used to derive peak and off-peak entraining loads to

arrive at total entraining load for platform.

 Train loads shall be based on crush load capacity of train in peak direction

and one-half seated load capacity of train in off peak direction.

 Total Occupant Load shall be the sum of the total entraining load and total

train loads based on crush capacity defined by Metro.

 Comparison of total entraining load to Net Platform Area divided by 4 square

feet per person shall be made to determine if constrained platform access

required.

 The greater number of total occupant load compared to Net Platform Area

divided by 7 square feet per person shall be made to determine number to

use for egress calculation.

Fare gate equipment used, including turnstile fare gates, ADAAG barrier leaf

fare gates, and emergency swing gates, shall be based upon the existing Cubic

Transportation Systems, Inc. (Cubic) design used on Metro’ s UFS Gating

Project.

Capacity for exiting for each fare barrier element shall be the following per

current edition of NFPA 130, Standard for Fixed Guideway Transit and

Passenger Rail Systems, NPFA 130:

 Turnstile Fare Gate Aisle: 25 PPM (People Per Minute) (2010 edition)

 ADAAG Barrier Leaf Fare Gate Aisle: 50 PPM (2010 edition)

 Emergency Swing Gate: PPM = Width of swing gate opening x 2.08 PIM

Gate-type exits shall be provided in each fare barrier to provide minimum of 50%

of total barrier exit capacity in accordance with current edition of NFPA 130,

Standard for Fixed Guideway Transit and Passenger Rail Systems, Section

5.5.6.3.3.4 (Doors and Gates, 2010 edition).
