Comment: 43 pages, 7 figuresManaging morning commute traffic through parking provision management has been well studied in the literature. However, most previous studies made the assumption that all road users require parking spaces at CBD area. However, in recent years, due to technological advancements and low market entry barrier, more and more e-dispatch FHVs (eFHVs) are provided in service. The rapidly growing eFHVs, on one hand, supply substantial trip services and complete the trips requiring no parking demand
on the other hand, imposes congestion effects to all road users. In this study, we investigate the multi-modal morning commute problem with bottleneck congestion and parking space constraints in the presence of ride-sourcing and transit service. Meanwhile, we derive the optimal number of parking spaces to best manage the commute traffic. One interesting finding is that, in the presence of ride-sourcing, excessive supply of parking spaces could incur higher system commute costs in the multi-modal case.
