Development of PennRoutes, a routing system to make Penn Shuttles more efficient and reduce emissions. Penn Shuttle drivers will enter passengers' addresses on a tablet. After all of the passengers are picked up, the driver will hit "start," and the system will automatically compute the shortest route through all the destinations. The PennRoutes system will also be capable of sending real-time information about the shuttle to Penn Transit; currently communication is done through radio. Penn Transit will also be able to quickly identify the closest shuttle when an off campus pick-up is requested.
