On-time performance LINK集

In transportation (such as municipal public transportation), schedule adherence or on-time performance refers to the level of success of the service (such as a bus or train) remaining on the published schedule.

There are many factors that can have an impact on on-time performance. Depending on the situation, the service may face regular delays or a service that usually performs on time may be occasionally behind schedule. Some of these factors include:

* Automobile traffic: The volume of traffic on the bus's route can impact the bus's ability to keep on the schedule. While a route that is free of obstruction can remain on schedule or even move ahead of schedule, heavy traffic can slow down the bus behind its schedule. This can be due to regular conditions at the time of day, or an occasional or one-time event, such as a sports game or festival that draws a large crowd.
* Accident: A collision that obstructs traffic can also tie up buses on the route until the accident is cleared and therefore cause them to be behind schedule.
* Detour: A road closure that forces the bus to temporarily deviate from its regular route may cause it take more time than planned to reach its destination.
* Weather: Inclement weather may cause a bus that usually remains on schedule to be behind as a result of precautions that must be taken by the vehicle's operator and other vehicles on the road.
* Increased ridership: When a special event takes place, the service may experience higher ridership levels than usual, leading to more time the bus or train may have to spend allowing passengers to board and depart.

Transit agencies often take the following measures in attempts to improve schedule adherence on their routes:

* Building more time into schedules. This may require the increased expenditure in the system's budget or else a slight reduction in service.
* Cutting other underperforming services. The savings generated from eliminating or reducing other services may be used to improve service on other, higher-performing routes.
* Modifying routes to a route where buses can be less obstructed, when this does not interfere with the ability of riders to reach their buses.
* Splitting a long route into two or more shorter ones, as shorter routes are more likely to remain on schedule.
