Heterogeneous fleet sizing for on-demand transport in …
This leads to less depreciation cost of the taxi fleet. A larger AVs-only zone means that more requests can be served by ATs instead of CTs which will also reduce the salary cost. The total profit does not decrease a lot in the SPM with different AVs-only zone sizes, as traffic congestion is the only factor that impacts the profit and the fleet ...
