human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "applications of the dynamic distance potential field method"):
  Abstract: Recently the dynamic distance potential field (DDPF) was introduced as a computationally efficient method to make agents in a simulation of pedestrians move rather on the quickest path than the shortest. It can be considered to be an estimated-remaining-journey-time-based one-shot dynamic assignment method for pedestrian route choice on the operational level of dynamics. In this contribution the method is shortly introduced and the effect of the method on RiMEA's test case 11 is investigated.

Includes members:
  Member "computation speed of the f a s t model":
    also connected through other hyperedges:
      (none)
  Member "counterflow extension for the f a s t model":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the use of dynamic distance potential fields for pedestrian flow around corners")
  Member "the f a s t model":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the use of dynamic distance potential fields for pedestrian flow around corners")
