add transit delay endpoint

[EddyIonescu]

• make this in an endpoint: https://www.toronto.ca/city-government/data-research-maps/open-data/open-data-catalogue/#bb967f18-8d90-defc-2946-db3543648bd6

@EddyIonescu I am working on this issue. You can find discussion about the opentransit-map issue page with Luke

You can follow the branch here: https://github.com/yubozhao/tryn-api/tree/22-map-incidents

also, any idea where is the dataset(file format/fields/etc)? Don't want to write that part yet, until we have something to look at.

[EddyIonescu]

@yubozhao, sorry, I didn't see this. Are you still working on this?
Here's the dataset for 2019 - https://www.toronto.ca/ext/open_data/catalog/data_set_files/Bus_2019.xlsx
Data for other years can be found at the link in the description.
Feel free to export it to CSV, then the API can just load it directly into memory.

[EddyIonescu]

Some more details:
For the date in startTime, return a list of all the delays for each route.
Each delay is an object containing the same info as each row in the delay spreadsheet.

incidents: {
  "39": [ ... ],
  "111": [ ... ]
}

That file is just for Jan 2019. Let's make it work for dates in January 2019 first, then expand it later.

• also, incidents would be loaded only when agency === 'ttc'. The route #s are the same as the ones the API already returns.

@EddyIonescu I am not working on it anymore. I was wondering why we were using Toronto's data instead of SF one, that is why I asked about where is the data(refer to SF)

[EddyIonescu]

@yubozhao I see, I started with Toronto since they have the data available and that they're the other city available in the web-app. I couldn't find any equivalent data for Muni, but I did send out a request a while ago but I'm still waiting for a response (will follow-up again soon).

It's pretty standard for agencies to record these kind of delays (ie. vehicle breaks down, not enough operators were available, car accident, etc.)...making them open is not though.

[yubozhao]

I am not sure how much the fetcher/parser will translate for SF muni's data. Since it is not available or we have a general timeline. I propose we hold off on this issue and related issue in the frontend, until the data is available for us to consume
