Abstract
Predicting pedestrian movement in unregulated traffic areas, such as parking grounds, marks a complex challenge in safety for automated vehicles. Without the ability to make certifiable predictions and judgments about safe interactions with other traffic agents in a real-time capable and economical fashion, the goal of self-driving vehicles cannot be reached. We propose a computationally efficient model for pedestrian behavior prediction on a short finite time horizon to ensure safety in automated driving. The model is based on a cellular automaton, working on an occupancy grid map and assumes a physical pedestrian capability constraint. It is enriched by a variable update rate with a mixed neighborhood, overcoming the limitations of vanilla cellular automata and coming closer to the results of state-of-the-art algorithms, while keeping the benefits of its straightforward parallelizability. The approach is evaluated on synthetic benchmarks outlining the general performance parameters as well as in an implementation on potential real-world situations.
