보행교통류를 위한 회전육각격자모형 개발 = The Rotated Hexagonal Lattice Model for Pedestrian Flow

다국어 초록 (Multilingual Abstract)

In this paper, the rotated hexagonal lattice model (RHLM) was proposed, which is applied to pedestrian flow, and developed the simulation model for the pedestrian counterflow . RHLM is an upgrade version of the square lattice model(SLM) and hexagonal lattice model(HLM). The simulation was performed at the hexagonal lattice 20×20 and evaluated by different speed, density and flow conditions. Simulation results are compared with SLM and show that RHLM can replicate the characteristics of pedestrian traffic more effectively and reliably than any other existing models from several perspectives. First, RHLM can explain the shortest-path movement of pedestrians and more realistic avoidance motion. If they cannot move straight direction, they can move shorter distance from previous position to destination. Second, RHLM reflects the characteristics that the pedestrian can move with higher capacity and the speed of pedestrian flow is hard to zero.

국문 초록 (Abstract)

본 연구에서는 SLM(Square Lattice Model)과 HLM(Hexagonal Lattice Model)을 개선하여 만든 RHLM(Rotated Hexagonal Model)을 제시하고, 이를 이용하여 양방향 보행 교통류의 시뮬레이션 모형을 개발하였다. 20×20의 400개 셀에서 진행되었으며, 시간의 변화에 따른 속도, 밀도, 교통류율로 평가하였다. 본 모형을 같은 조건에서 SLM과 비교해본 결과, 기존의 모형이 보행자의 움직임이 불필요한 동작과 비논리적 방향으로 이동하는 것을 모형에 반영 하였다면, 본 모형은 보행자의 직진 움직임과 자연스러운 회피 방법을 통해 보행교통류의 최단경로 움직임을 표현할 수 있었다. 또한 보행교통류의 더 높은 곳에서 용량을 가지고 보행을 할 수 있는 현상을 반영할 수 있었고, 보행교통류의 경우 밀도가 높아지더라도 속도가 0이 되는 상황은 잘 일어나지 않는 것을 반영할 수 있음을 알 수 있었다.
