Subway Environment Simulation

The Subway Environment Simulation (SES) Computer Program and Subway Environmental Design Handbook were developed in the early 1970's under sponsorship of the Urban Mass Transportation Administration (former name of the Federal Transit Administration) to assist in the planning, design, and construction of subway ventilation systems. The SES fulfilled an unmet need in the transit engineering community, and has been widely used in the design of new rail systems or line extenstions in: Washington, District of Columbia; Atlanta, Buffalo, Baltimore, Dallas, Los Angeles, San Francisco, Montreal, Toronto, the Seattle Bus Tunnel, and in rail transit systems around the world. The SES provides tunnel designers with the tools to: properly size and locate ventilation shafts, evaluate tunnel geometry and fan size, optimize temperature, and model the effects of heat and smoke resulting from fires and other sources. The most recent enhancement is the validation of the subroutine which describes the behavior of smoke in emergency conditions.
