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 effect on gridlock.

Mark Ryan and Alina Li Zhang demonstrate an approach that uses time series forecasting and deep learning to predict streetcar delays. You’ll learn the economic impact of the streetcar-trigged gridlock on Canada’s largest city and the development environment Mark and Alina used to tackle the problem. They outline the source data and cleansing process with a focus on the challenges and opportunities of dealing with wild data and share the essential points of time series focusing as they applied it in conjunction with deep learning. You’ll see the results of their analysis, including practical recommendations for Toronto’s transit authority (the TCC) to resolve the problem of streetcar delays so the city can continue to enjoy the character and soul of its unique street railway for the rest of the 21st century.
