In larger cities such as Lyon or even Dublin, bikeshare schemes are quite successful. In smaller ones like Limerick they struggle. I am convinced the problem is critical mass. As a scheme gets bigger, it provides disproportionately more possible useful journeys (as long as there is the population density to support it).
I want to model this. Let’s start by imagining cities that are big enough to sustain a square grid of bike stations, and let’s count the number of possible A-B journeys it provides (of different distances).
