Pedestrian and Evacuation Dynamics 2012 The 6th International Conference on Pedestrian and Evacuation Dynamics conference (PED2012) showcased research on human locomotion. This book presents the proceedings of PED2012. Humans have walked for eons; our drive to settle the globe began with a walk out of Africa. However much remains to discover. As the world moves toward sustainability while racing to assess and accommodate climate change research must provide insight on the physical requirements of walking the dynamics of pedestrians on the move and more. We must understand predict and simulate pedestrian behaviour to avoid dangerous situations to plan for emergencies and not least to make walking more attractive and enjoyable. PED2012 offered 70 presentations and keynotes and 70 poster presentations covering new and improved mathematical models describing new insights on pedestrian behaviour in normal and emergency cases and presenting research based on sensors and advanced observation methods. These papers offer a starting point for innovative new research building a strong foundation for the next conference and for future research
