Clarifying questions:

• When you say ridesharing rides, do you want to count rides taken to and from airports using Uber/Lyft? yes
• We are only focusing on rides to and from the airport? yes
• Do we want to calculate the number of rides for a specific airport or a geographic area such as the US/Canada? Let’s pick one airport. OK I can use SJC as the location.
• Do we want a count for each day/ month or 12 month? Let’s calculate for a day.

Ok, so to summarize the question again-

Calculate how many airport rides are taken by travelers to and from SJC airport in a day using Uber and Lyft.

Let me brainstorm how I would like to calculate this number:

Formula:

number of travelers using ride-sharing services = (number of planes to/from SJC * number of travelers on each plane ) – ( travelers who park and fly + travelers who get family/friends to drop off)

Daily rides using ride shares to and from airport= number of users/ 3 (each car can fit 3 passengers on avg)

planes at SJC = 24* 60 /5 = 280 planes a day –one plane every 5 minutes

total travelers at SJC = number of planes * travelers on each plane= 200*280 = 56000 = 50K rounded.

20 % of the travelers get friends and family to drop off, 10 % park and fly, 10% take public transport,  60% of the travelers to the airport using ride-sharing services.

Formula: 50K – (10K+5K+5K) = 30K

travelers mostly have luggage, some are single travelers, some travel with family, let’s say single travellers opt for car pool, which means each ride can fit 3 riders.

30K / 3 = 10K rides every day.
