Putting People in Their Places
A STEPS animation sequence can help architects determine how crowds might behave in certain spaces.
By Kenneth Wong
There’s one aspect of AEC that has less to do with measurements and aesthetics and more to do with behavioral science. To outsiders, and even to some industry insiders, this specialized discipline seems more speculative than deductive, more artificial (as in artificial intelligence, or AI) than architectural. It’s computer-aided crowd movement simulation, often used to study how occupants might interact with the living space around them.
Game developers and filmmakers routinely use the same technology to digitally populate their scenes. But recent advances in hardware horsepower and visualization algorithms have pushed this technology toward a new science, now trusted by AEC consultancies. At SIGGRAPH 2007 in August, Massive Software, known for its AI engine in the video game and film industries, began courting the AEC market (see “Animation Possibilities for AEC,” AEC Tech News 208).
But Mott MacDonald Group, an engineering consultancy, preceded Massive in this endeavor. Mott MacDonald developed Simulation of Transient Evacuation and Pedestrian Movements (STEPS), a software product described as “a microsimulation tool” to help its clients better understand pedestrian movements inside architectural structures.

Share and Share Alike (AEC Insight Column)
By Jerry Laiserin
Access to files, documents, and information located elsewhere is one of the most valuable functions provided by online media such as the Internet. For collaborative industries, such as AEC/O, the ability to exchange, view, and act upon shared information is the lifeblood of business and business processes.
Almost any form of AEC/O information–based activity -- document transmission, storage, retrieval, mark up, routing, workflow, review, approval, and so on -- that can be performed in the physical world can now be performed by a range of online means and services. Read more »
