B.1 GENERAL APPENDIX B EXITING ANALYSIS B.1.1 As described in Section 2.2, there shall be sufficient exit capacity to clear the platform occupant load from the station platform in 4 minutes or less, and the station shall be designed to permit evacuation from the most remote point of the platform to a point of safety in 6 minutes or less. B.1.2 Platform exit time is the time required to clear all the platform occupant load from the platform according to the formula: Time to clear platform = Platform exits flow time = Platform Occupant Load / Platform Exit Capacity B.1.3 The time to evacuate from the most remote point of the platform to a point of safety is the sum of the walking travel time for the longest exit route plus the waiting times at the various circulation elements. B.1.4 The walking travel time is calculated using station geometry data and the travel speeds indicated in Cl.2.2.3.7. The exit route is broken down into segments and tabulated. The travel distance for each segment is then divided by the appropriate travel speed to determine the time needed to traverse each segment. The walking travel time is the sum of the times for each segment. B.1.5 The flow time (the time for the last person to through the particular element) for each of the various circulation elements (e.g. stairs/escalators, fare collection gates, doors, etc.) is calculated using the capacities and conditions specified in Section 2.2 along with the occupant load calculated as described in Appendix A. B.1.6 Care must be taken to be sure that the most restrictive circulation elements are included in the calculations. For instance, if a 1000mm wide single-leaf door provides access to a 1200mm wide stair, the door and the stair would be considered to provide a capacity of 80p/min and 72p/min respectively in accordance with Cl.2.2.3.7. In this case the stair is more restrictive than the door, meaning that the stair shall be used in the capacity calculation.
