Quel rôle du réseau de voirie urbaine sur la distribution des flux piétonniers ?

subject

description

In the urban networks, the pedestrian frequency of streets is variable. At an aggregated level, it partially depends on the spatial configuration of the urban network. This concept, called the “natural movement”, is a key-notion in space syntax. It is here investigated by assuming several explanatory factors: metric accessibility, network linearity, route linearity, route continuity. Data obtained from a pedestrian movement survey in the city of Lille (France) were used. The factors were represented by series of theoretical frequencies defined with origin and destination points stemmed from real trips. These theoretical frequencies were compared to the observed pedestrian frequencies. The statistical analysis showed that metric accessibility is the first factor explaining the pedestrian flows distribution (60% of variance). The level of route linearity is just a secondary but significant factor.
