Quantitative Comparison Between Crowd Models for Evacuation Planning and Evaluation

Crowd simulation is rapidly becoming a standard tool for evacuation planning and evaluation. However, the many crowd models in the literature are structurally different, and few have been rigorously calibrated against real-world egress data, especially in emergency situations. In this paper we describe a procedure to quantitatively compare different crowd models or between models and real-world...

A Comprehensive Evacuation Planning Model and Genetic Solution Algorithm∗

We consider the problem of evacuating an urban area caused by a natural or man-made disaster. There are several planning aspects that need to be considered in such a scenario, which are usually considered separately, due to their computational complexity. These aspects include: Which shelters are used to accommodate evacuees? How to schedule public transport for transit-dependent evacuees? And ...

Multi-time Models for Temporally Abstract Planning

Planning and learning at multiple levels of temporal abstraction is a key problem for artificial intelligence. In this paper we summarize an approach to this problem based on the mathematical framework of Markov decision processes and reinforcement learning. Current model-based reinforcement learning is based on one-step models that cannot represent common-sense higher-level actions, such as go...

Making the Abstract Concrete 1 Running Head: Visualizing Mathematical Solution Procedures Making the Abstract Concrete: Visualizing Mathematical Solution Procedures

This article reports on an experiment investigating the effects of different kinds of computerbased visualizations on the acquisition of problem-solving skills in the domain of probability theory. Learners received either purely text-based worked examples, text plus an instruction to mentally imagine the examples’ contents, or the possibility of retrieving either static pictures or concrete ani...
