LEGION's unique, in-house, mathematical model of human movement is recognised by users and researchers as more rigorously and scientifically accurate than the best alternative academic and commercial output. This allows the most reliable virtual assessment of populated infrastructure assets currently available. So, designers and developers of such assets can understand the performance characteristics of their specific, planned structures. This helps to ensure fitness for purpose of new buildings, and to extend the useful life of existing ones, so safeguarding, and maximising return on, capital outlay.
LEGION offers modelling, simulation and analysis of pedestrian movement in a BIM environment and as part of OpenBuildings Station Designer, includes support for easy CAD preparation from BIM data. Its people, known as entities, sample their space and speed preferences from distributions measured from video of real crowds and walkers. Their aims and objectives are given by users. The algorithm governing their movement minimises sacrifice in fulfilment of preferences and progress towards objectives. In executing it each step, while interacting with others and their environment, entities show perception, avoidance, memory, adaptability and other aspects of intelligence. Moreover, the patterns, structures, flow rates and densities that emerge from their collective behaviour match those found in real crowds.
Independent corroboration from numerous third parties and a 20-year history of projects, worldwide, are testaments to the validity of LEGION’s simulator. Furthermore, its intuitive visual output supports application to important commercial needs, including
