Mott MacDonald services

At the forefront of transit environment system design for many years, Hatch Mott MacDonald’s cutting-edge skills successfully address the various issues associated with the design of systems for today’s modern rail and road networks. Remaining at the forefront of tunnel ventilation, operation, and control, HMM maintains a serious and active interest in these issues worldwide and continuously participates in and monitors advances in technology and methodology.

Hatch Mott MacDonald has developed the STEPS program (Simulation of Transient Evacuation and Pedestrian Movements) to simulate the movement of people under both normal and emergency conditions. Office blocks, sports stadiums, shopping malls, and underground stations are all examples of areas where there is a need to ensure uncomplicated transitions in normal operation and rapid evacuation in the event of an emergency. Optimization of people flow through simulation can provide a more agreeable environment and more effective fire safety design in large and crowded places.
