      abstract     = {The Hermes project [1] demonstrated the usefulness of on
                      site faster than real time simulations of probable
                      evacuation scenarios for security personnel. However, the
                      hardware needed was prohibitively expensive [2]. The present
                      paper shows that a multiscale approach can perform the
                      simulation in a fraction of time without loss of useful
                      information. The main problem is the correct passing of
                      agents from a coarse scale model to a fine scale model, here
                      from a CA model to a force based model. This will be
                      achieved by inserting agents into the force based model at
                      positions and speeds optimized for smooth walking either by
                      a priori information or using Voronoi cells. Connecting a
                      Queue model to a continuous model has already been done
                      successfully [3].We also show that a slightly modified CA
                      method can address the problem, too, at even less
                      computational cost, with some possible loss of accuracy.},
