There are a few reasons why a bus could pass you up such as: the bus is already at full capacity and is unable to board additional passengers, the bus is out of service, or the bus is being used to fill in for only a portion of a route to close gaps in service that may have been caused by roadway congestion, traffic accident, or some other valid reason. The bus is not required to stop at each bus stop if there are no customers waiting. Please be sure to make yourself visible to the operator at the bus stop and make sure to verify the time that the bus is scheduled to arrive.
