Our program was able to provide rides for the students represented by our CarShare models. Not only does our solution work for the Gephardt Institute’s needs, it would save them over 30% in transportation expenses, as shown below.

Seeking to go above the Gephardt Institute’s needs, we ran our program on our large expanded model. We also ran our program using our alternative solutions, adding a zoning component. Statistics on the solutions as the passengers are scaled are shown here.

Our zoned solution provides particularly exciting results. By having one driver go to a few nearby locations, we can serve over 85% of students in even our largest model. This alternative solution also lowers the overall cost for the Gephardt Institute even more than our general solution, shown here.

As such, we recommend utilizing the zoning technique when the program is implemented.

Our program was also able to accommodate different sized cars, for example a sports car or minivan. The effects of this accomodation on successful passenger matching and cost savings vary depending on driver availability (i.e. If a driver with a minivan is only available when one passenger requests to volunteer, the different car size will have no effect). Sample results are shown below.
