Local aspects of vehicular pollution

We consider the local aspects of vehicular pollution by wind tunnel testing used in conjunction with a tracer-gas technique. These initial results show that the level of pollution received by a commuter in slow-moving heavy traffic may be as much a function of the pollution produced from the car in front as other environmental aspects.

Wind around tall buildings

Tall buildings can deflect high-level wind down towards the ground, producing unpleasant and sometimes dangerous winds in adjoining pedestrian areas. Architects, planners and developers must aim to provide safe and comfortable conditions in open-air pedestrian areas; they should, therefore, understand how the wind flows around buildings and how to control it by good design.
