The results show that the distance to the city center and the number of entrances are the two most significant impact factors, while other built environment factors show varying degrees of influence. Interestingly, secondary and primary road densities play a significant role in predicting the usage of bikesharing and ridesourcing services, respectively. Moreover, nonlinear effects of the built environment have been investigated. For example, when secondary road density is below 5.2 km/km<sup>2</sup>, it has a positive effect on bike-sharing usage. However, this relationship does not hold when the secondary road density exceeds this threshold.
