  With the increasing popularity of ride-hailing services, new modes of
transportation are having a significant impact on the overall performance of
transportation networks. As a result, there is a need to ensure that both the
various transportation alternatives and the spatial network resources are used
efficiently. In this work, we analyze a network configuration where part of the
urban transportation network is devoted to dedicated bus lanes. Apart from
buses, we let pool ride-hailing trips use the dedicated bus lanes which,
contingent upon the demand for the remaining modes, may result in faster trips
for users opting for the pooling alternative. Under an aggregated modelling
framework, we characterize the spatial configuration and the multi-modal demand
split for which this strategy achieves a system optimum. For these specific
scenarios, we compute the equilibrium when ride-hailing users can choose
between solo and pool services, and we provide a pricing scheme for mitigating
the gap between total user delays of the system optimum and user equilibrium
solutions, when needed.
