Stations, like airport terminals and other places of assembly, require the many capabilities of RWDI because of their size, their association with polluting vehicles, and their need to ensure safety and comfort on the part of their users. A wide variety of RWDI capabilities are applicable to such projects.

Internal Ventilation

Air quality in subway stations, airport terminals, and commuter bus / rail terminals, is affected by both the amount and distribution of ventilation air. Correct design ensures proper air distribution and can reduce outside air and energy requirements.

Fire Safety

Fire safety and smoke control are important issues in the design of terminals. In the event of a fire, ventilation systems must be designed to ensure safe escape paths and to minimize property damage.

Air Quality

Exhaust from cars, trucks, trains, and buses may impact on nearby environments, residences, and pedestrian areas. The negative effects of exhaust can be reduced if mitigative measures are implemented in the design of transportation facilities such as stations.

Wind Loading

Roofs and walls of major structures, require accurate information on static and dynamic wind loads.

Snow

Snowdrifting can increase maintenance costs. Snow loads on large roofs, such as stations or airport terminals can be excessive and result in structural failure. Accurate snow load information improves safety and economy of design.

Noise / Acoustics / Vibration

Government agencies require noise impact statements for new transportation facilities. Mitigative measures can eliminate or reduce these impacts.  Passenger comfort can be improved through acoustical optimization.

Pedestrian Comfort

The design of a transportation project can influence local wind activity, thereby impacting safety and the quality of the environment for pedestrians. Wind breaks, screens, and minor modifications to the design of a structure can improve wind conditions at entrances or platform areas.
