Motivation

In this project, we try to integrate global and local path planning. By combining those, we can put interesting constraints and reality in simulation. One example is agents chasing a target based on their own local information. In real world, agents are usually have limited vision so that they should decide their path with their eyes. Moreover agents chasing the target in crowded environment should avoid dynamic obstacles in clever ways. In addition, we hope to see both methods working together and to compare them.

Scneario

  1. Crowd of pedestrian are heading to each end of road.
  2. Small numbers of Anderson are trying to find Neo based on their vision and communicate each other.
  3. Neo is trying to escape from Anderson and heading for specific target.

Continuum Crowd

Cognitive Modeling

Tasks

  1. Simulate crowd of pedestrian agents based on Avneesh's work
  2. Anderson and Neo use local information to chase and escape
    1. While detecting, Andersons should cover as most place as possible (exploring)
    2. Andersons find the chasing path to Neo using D* or any other dynamic path planning algorithm (path finding)
  3. Integrating 1) and 2)
