Corner-to-Corner (C2C) Strategy

The Corner-to-Corner (C2C) strategy is an optimization based strategy that allows TNC operators to pickup and drop-off requests at links that are within a walkable range from the actual origin and destination respectively. This strategy can be operated with or without Dynamic Ride Share (DRS). Corner-to-Corner assignment helps to reduce VMT per served request by up to 10% compared to conventional Door-to-Door services.

Link based routing is used in this strategy instead of location based routing in order to have more control on where the requests get picked up and/or dropped off. The strategy has been implemented in POLARIS in such a way that the user can decide whether to adjust pickup and drop-off locations before or after the iterative optimal request-vehicle matching stage in each batching interval. Other important parameters that can be changed are the pickup and drop-off walk ranges, number of alternative candidate pickup/drop-off links to consider, and flags to selectively enable or disable pickup or drop-off link adjustment.
