Encouraging pedestrian activity is increasingly recognised as beneﬁcial for public health, the environment and the economy. As our cities become more crowded, there is a need for urban planners to take into account more explicitly pedestrian needs. The term that is now in use is that a city should be ‘walkable’. For route planning, whereas much attention has been given to shortest path, in distance or time, much less attention has been paid to ﬂow levels and the diﬃculties they pose on the route. This paper considers problems posed by conﬂicting paths, for example cross-traﬃc. We use network centrality measures to make a ﬁrst estimate of diﬀering levels of conﬂict posed at the network nodes. We take special note of the role of collective motion in determining network usage. A small case study illustrates the method.
