Abstract:Rail transit systems make extensive use of escalators at the stations to facilitate efficient patron flow. Escalators are available with design features such as dual speed (90 and 120 fpm), mat operation, and flat steps. This study has evaluated the design features based on the impact of each on capital and operating costs, traffic flow, and safety. These design features were evaluated on the basis of analyses of data collected from transit properties and manufacturers. A human factors engineering model was developed to analyze the need for flat steps at various speeds. The study concluded that mat operation of escalators is cost effective in terms of energy savings. Dual speed operation of escalators with the higher speed used during peak hours allows for efficient operation. Minimum number of flat steps required as a function of escalator speed were developed to ensure safety for the elderly patrons.
