19. The Problems We can’t see into the future It’s a dynamic scenario
Peak hours need significantly more vehicles than any other time of day
Constraints on costs
No historical perspective

20. The Approach Started with a ceiling number
Cars only come back at the end of the day
Start by analyzing each type of vehicle separately
Predicted rush hours

21. The Next Steps Move cars from neighboring pixels
Return cars from other counties dynamically
Minimize empty vehicle miles
