ETA（预计到达时间）在Lyft的可靠性

Imagine this: You’ve got a crucial early morning flight to catch — you open the Lyft app, and see an estimated pickup time on the screen. But here’s the million-dollar question: Will the driver you are paired with, arrive at the estimated time? One of Lyft’s most simple, yet profound goals is to ensure we provide riders with the most accurate ETAs we can.

想象一下：您有一个关键的早班飞机要赶 - 您打开Lyft应用程序，屏幕上显示了一个估计的接送时间。但是这是百万美元的问题：您配对的司机会在预计时间到达吗？Lyft最简单但又最深远的目标之一是确保我们尽可能为乘客提供准确的ETA。

Before you even hit ‘request’ and summon a ride, there are complex algorithms that sift through historical and real-time data, leveraging machine learning alongside traffic and weather insights to predict the ETA (or pickup time) to display on the rider’s screen based on the destination they input. This got us thinking — how do we determine ETA estimates as accurately as possible, before a rider requests a ride?

在您点击“请求”并召唤一辆车之前，有复杂的算法通过历史和实时数据，利用机器学习以及交通和天气信息来预测基于乘客输入的目的地的ETA（或接送时间）并显示在乘客的屏幕上。这让我们思考 - 如何在乘客请求乘车之前尽可能准确地确定ETA估计？

Enter: Reliability

进入：可靠性

What does ‘reliable’ really mean in this context?

在这个背景下，'可靠性'到底意味着什么？

In the realm of ridesharing, ‘reliability’ takes on different dimensions depending on the ride’s phase — be it prior to a rider requesting a ride, after the ride has been requested, or after the details of the driver who has accepted the rider’s offer, emerge. For instance, once a driver’s information is visible, reliability translates to the accuracy of the predicted driver arrival time (displayed on the screen) compared to the driver’s factual arrival time.

在打车领域，'可靠性'在不同的情况下具有不同的维度 - 无论是在乘客请求乘车之前、乘客请求乘车之后还是在乘客接受司机的报价之后。例如，一旦司机的信息可见，可靠性就体现为预测的司机到达时间（显示在屏幕上）与司机实际到达时间的准确性。

So, what encompasses reliability before a ride is even requested?

那么，在乘车请求之前，可靠性包括什么？

Simply put — Given an ETA before a ride request, reliability is the likelihood that a driver will arrive within a reasonable timeframe around that ETA, should the ride be booked.

简单来说——在乘车请求之前给出一个ETA，可靠性是指司机在该ETA周围的合理时间范围内到达的可能性，如果乘车被预订。
