您将学到什么 (What you'll learn)

- applying time-series forecasting in machine learning - applying machine learning to resolve fundamental transit issues

描述 (Description)

Toronto is unique among North American cities for having a legacy streetcar network as an integral part of its transit system. The streetcars are icons of the city and make a unique contribution because of their passenger capacity and zero emissions. However, because most of the streetcar network shares streets with other vehicles, and because unlike buses streetcars cannot move around obstacles or be quickly towed away if they break down,
streetcar delays have a disproportionate on gridlock.

This session will demonstrate an approach that uses time-series forecasting and deep learning to predict streetcar delays.

- First, the nature of the problem will be described in more detail, including the economic impact of streetcar-triggered gridlock on Canada’s largest city.
- Next, we’ll describe the development environment we used to tackle the problem.
- Then we’ll describe the source data and cleansing process, with a focus on the challenges and opportunities of dealing with “wild data”. We’ll describe the essential points of time-series forecasting and how we applied it conjunction with
deep learning.
- Finally, we’ll share the results of our analysis, including practical recommendations for Toronto’s transit authority (the TTC) to resolve the problem of streetcar delays so that the city can continue to enjoy the character and soul of our unique street railway for the rest of the 21st century.
