BART PATRON EGRESS/INGRESS STUDY: USE OF STAIRS AND ESCALATORS BETWEEN PLATFORM AND CONCOURSE LEVELS

The shorter headways planned for 1989-1990 and the increased patronage projected over the next 5 years caused concern about the capacities of the Bay Area Rapid Transit (BART) stations to handle exiting patron loads. A basic objective at BART has been that patrons from one train should be off the platform before the next train coming from the same direction arrives; that is, within the existing headway. To analyze the patron egress/ingress capacities of BART's stations, five parameters were considered: (a) the planned headways between trains, (b) the projected patronage at each station, (c) the availability of escalators, (d) the processing rates for the stairs and escalators, and (e) the number of patrons that can be expected to use the stairs. On the basis of these five parameters, a basic criterion was developed: The projected 95th percentile of peak patron loads during the exit rush 2 hours should be able to use the stairs and escalators to exit the platform within 2.25 min, even if one escalator is unavailable. Each station was analyzed under four conditions. The analysis revealed that nine stations would have problems in the 2.25-min time frame when one escalator is unavailable. Each of the nine stations was evaluated in detail, and preliminary recommendations were made for the number of escalators or stairs to add to the stations. To facilitate a decision on constructing an escalator or stairwell at each station, cost estimates should be obtained and considered in light of the indicated severity of potential egress/ingress problems.
