Modeling pedestrian dynamics in Montreal's underground city

This study is an examination of the daily dynamics and system stability of pedestrian movement within an extensive, indoor walkway system. Temporal an d spatial stability in the distribution of pedestrians was established usin g an efficient census-taking technique. It was found that the spatial distr ibution of pedestrians was weakly related to the integration of the Undergr ound system. Centrally located links were marginally more attractive to ped estrians. Relatively minor differences in pedestrian distribution were disc overed between weekday and weekend day. The absence of directional flows ov er time was also observed. The highly stable dynamic structure of the Under ground is in direct relationship with a describable urban environment. This paper concludes with recommendations for research into other explanatory e nvironmental factors.
