Abstract:With improvements in 2-dimensional modelling of flood flows, associated with increasing computer power and visualisation, the use of agent-based modelling to investigate receptor behaviour and fate has become more widespread. One such agent model is the Life Safety Model (LSM) which was developed originally for dam break assessments and for informing reservoir evacuation and emergency plans. Although LSM was developed some 15 years ago, HR Wallingford only became involved in its use in 2006, and since the start of 2012 has been responsible for its technical development and commercialisation. Over the past 10 years the model has been applied to a range of flood hazards, including coastal surge, river flood, dam failure and tsunami, and has been verified against historical events. Commercial software licences are being used in Canada, Italy, Malaysia and Australia. Alongside the increasing and more widespread use of the model, a core group of LSM users and analysts has been specifying and delivering a programme of model enhancements. These include improvements to traffic behaviour at intersections, new algorithms for sheltering in high-rise buildings, and the addition of monitoring points to allow detailed analysis of vehicle and pedestrian movement. Following user feedback, the ability of LSM to handle large model ‘worlds’ and hydrodynamic meshes has been improved. Overall, there is an active programme of improving the model following user comments. This includes new documentation, performance enhancements, better logging of run-time events and bug fixes. This paper will describe some of the recent developments and summarise some of the case study applications, including dam failure analysis in Japan and mass evacuation simulation in England.
