Drive times: Google Maps Routes API (January 2026). We assume 45% peak hours (7-9am, 4-7pm weekdays) and 55% off-peak (red-eyes, midday, weekends).
Traffic buffer: SFO’s unpredictability means ~35% extra buffer vs ~15% for OAK. Valued at 50% of hourly rate per USDOT guidance.
Costs: Uber/Lyft ~$2.00/mi + $3 base. Parking averages $8.50/day cheaper at OAK (Economy: $18 vs $25, Daily: $26 vs $36). CO₂ at 0.89 lbs/mile per EPA.
Annual savings = productivity (time saved × hourly rate) + traffic buffer value (reduced uncertainty × 50% hourly rate) + transport savings (rideshare trips: shorter distance × $2/mi; parking trips: $8.50/day + gas).
