To select the 10 drop-off and pick-up locations, my initial step would involve researching key areas in Palo Alto, including schools, shopping centers, office complexes, and residential neighborhoods. I would take into account peak usage times and overall ridership to identify locations that currently attract the highest volume of riders. In addition to these venues, I would also consider significant public transit hubs, which are ideal for pick-up and drop-off due to their high concentration of potential riders. Lastly, I would assess the traffic network's load, opting for pick-up and drop-off sites located on main roads with multiple lanes to facilitate smoother management during peak hours. Using these criteria, I could pinpoint the 10 specific locations. The primary aim is to reduce waiting times and congestion while maximizing the efficiency of the self-driving cars.
