| Oasys Software's MassMotion delivers 3D crowd simulation that’s scalable for projects of all sizes With flagship projects like the 10-year redevelopment of Toronto's Union Station, New York's Hudsons Yards and a host of airport terminals and sports stadia on its CV, Oasys Software's MassMotion is maintaining its thought and technical leadership in crowd simulation. It informs and influences design, it streamlines construction keeping everyone on site safe, and it communicates results in a highly visual manner that is meaningful to all stakeholders and decisions makers. With outputs that are as close to real life observations as it is possible to get, 3D geometry tools that make it the only solution that is a direct BIM 'plug-in', and the smartest agents (or avatars), MassMotion is high on any engineer's wish list. In addition, new SQL database-driven storage simulation data and highly flexible analysis tools makes MassMotion faster and more flexible than ever before. All this adds up to a powerful, scalable tool that is proving to be equally suitable for smaller-scale projects, with pricing that allows for a rapid return on investment. Rarely is this speed and flexibility more important that the redevelopment of a railway interchange, where there will be no question of suspending transport services during a project or excluding the travelling public from the scene altogether. The 10-year project at Union Station, Toronto involves three major capital projects to make train, subway and train shed facilities fit to cater for 250,000 people per day. When the project master plan was adopted in 2004, Arup was awarded the contract to assess the pedestrian flows through Union Station during refurbishment and through to 2021. MassMotion revealed a number of opportunities and constraints for the refurbishment project, as well as informing the best locations of retail, commercial and transit-related facilities. Clearly, there is more to crowd modeling than emergency evacuation planning, and a growing recognition of its importance in future urban redevelopment. MassMotion is looking to that future and is able to simulate the behaviour of crowds of hundreds of thousands of people across whole districts. It is, however, equally useful for exploring the behaviour of a few thousand people in a more limited space, and it can do this in real time, drawing from data in standard CAD models and scheduling agents with individual agendas, such as a need to get to a rail platform, grab a bite to eat or an inclination to choose stairs over escalators. This behaviour is informed by academic research into the nature of how crowds move (Fruin et al) with mathematical models replicating these movements (Helbing et al).
RISK IS NOT SCALABLE That it all went so smoothly was in no small part due to the crowd modelling work undertaken by the Arup team who are facilitating construction work. Their job is to ensure continuing passenger safety and plan for emergency evacuation throughout the four and a half year transformation, responding quickly to multiple contractors requirements to close, say, an escalator or a platform. To this end they have introduced Oasys's MassMotion 3D crowd simulation software to the Network Rail project, and their crowd simulation work is underpinning construction staging throughout the project. Alan Wilson, lead fire engineer in the Arup team based at New Street throughout the whole project, has responsibility for delivering crowd management solutions that will accommodate the needs of multiple construction teams. MassMotion gives his team the essential speed and the flexibility to do this, typically delivering results within the hour, revealing potential bottlenecks and issues which hand calculations would have missed. Importantly, they can also quickly interrogate the model to explore alternative solutions. MassMotion's highly visual, genuinely 3D output gives clear information to the stakeholders who must approve each proposed change, in this case the Fire Brigade and Network Rail. Alan Wilson says: "I have no doubt that MassMotion has been instrumental in keeping the construction process flowing. On the Birmingham Gateway project it has more than proved itself as a tool for managing crowd movements at any scale."
WHAT'S NEW IN MASSMOTION 6.0 FOR 2014? MassMotion 6.0 also introduces a new user interface that adds a range of powerful new features, such as dynamic scene search, select anywhere behaviour, time tables, and dynamic properties now make it easier to work with your data, while high-quality real time 3D graphics and direct image and video capture make it easier to build materials and presentations. other new features include:
• New database back-end for storage of simulation results Viisit the Oasys website at: www.oasys-software.com | ||
