Path Analysis Using Directional Forces. A Practical Case: Traffic Scenes

摘要

This paper presents a new solution for path analysis using minimal path techniques with external directional forces. Previously techniques presented in the literature need to store every different path that exists in the scene. This is a problem in terms of memory. They also need the complete route to perform the computation, being unable to be used detecting uncommon events, like accidents, in real time. We introduce a path planning technique that, using only a velocity field, is able to cope with these problems. The technique can be used with no information a priori about the environment, while it is possible to include or even modified it. A case of study based on traffic analysis is presented to show the performance of the methodology. A complex turnaround scene along with highway real data tested our methodology, showing promising results.
