A hybrid trip planning system comprising: one or more processors (711; 810); and one or more memory resources storing instructions that, when executed by the one or more processors, cause the one or more processors to: receive a transport request from a requesting user; determine a pick-up location and a drop-off location from the transport request; based at least in part on the pick-up location, determine a set of candidate vehicles to service the transport request, the set of candidate vehicles comprising a blend of non-autonomous vehicles and autonomous vehicles, AVs; select an autonomous vehicle, AV, from the set of candidate vehicles to service the transport request based on the pick-up location and the drop-off location identified in the transport request fulfilling a set of criteria which enables availability of autonomous transport services, wherein the set of criteria includes a minimum distance percentage in which the selected AV must be in the autonomous mode between the pick-up location and the drop-off location; determine (i) a plurality of entry points from the pick-up location to an autonomy grid on which the AVs operate, and (ii) a plurality of exit points from the autonomy grid to the drop-off location; determine an optimal entry point from the plurality of entry points and an optimal exit point from the plurality of exit points; and transmit transport data to the selected AV, the transport data providing (i) a first optimal route for a human safety driver to drive the selected AV in a manual mode from the pick-up location to the optimal entry point, at which the selected AV switches into an autonomous driving mode, and (ii) a second optimal route for the human safety driver to drive the selected AV in the manual mode from the optimal exit point to the drop-off location. one or more processors (711;
