Description
On-Time Performance (OTP) is a probabilistic measure that tells the customer the likelihood that the trip they are about to take will arrive "on-time." However, this metric forces the customer to think in terms of a probability of trip timeliness and not an actual time value for how timely the trip will be. This presentation will explore a new way to examine on-time performance by quantifying the timeliness of trips. Customers can then use this information to determine which trip would be the best to take based on when they need to arrive at their destination. Using a system science approach, this new method will take into consideration the impact of service disruptions, reroutes, service failures, and other factors on the timeliness of route trips. This metric is especially important for customers who are attempting to make connections that hinge on reliable and timely travel times.
