Hi nwootton,
thanks for the great module. I am using it for my mirror project and encountered a weird issue:

I use it for two bus routes (44 and 344) and what I noticed during the weekend is that very early buses (like 01:00 in the morning or so) got delayed. BUT they got delayed more and more according to the module which causes the timing to be off. Eventually the timer showed something like “1756 Minutes late”. These late runners did not disappear but would always stay on top of the list.

I understand that this might be a bug on TFL’s side but is there a way to have buses that are, lets say more than 60 minutes delayed, shown as cancelled or have them faded out? For routes that are running like every 5-10 minutes usually this might make sense I think.

Thanks in advance
Dave

@Davepre I’ll have a look and see what I can do. Can you tell me all the bus stop codes you are using?

It’s possible that TfL (or whoever) is not passing the info across to Transport API or that Transport API are not passing it down to the module correctly.

The more common error is that the bus operators don’t actually send anything and this was breaking the module.

Hi Nick,
thank you very much for your reply.

I am currently only using one bus stop. “The Latchmere” stop LS which has the AtcoCode “490013443E”.

Thanks again for looking into this!

490013443E

Can you send me the config you are using - I can see weird things happening with the feed - e.g. 08:45 seems to become 00:45 for some reason, but I’d like to make sure that I’m setup the same way as you.

Davepre

Thanks for looking into this. I am at work at the moment and dont have access to the mirror here, but will send you the config files as soon as I am home!

thanks and best regards

@Davepre

The issue is with TransportAPI and I’ve contacted their support with the following info:

Using ‘https://transportapi.com/v3/uk/bus/stop/490013443E/live.json?app_id=a111aa11&app_key=1a11111a1111aaa11a1a1111a11111a1&group=route&nextbuses=no’

I get the following info (snippet):

departures: 
{
44: 
[
{
mode: "bus",
line: "44",
line_name: "44",
direction: "Victoria",
operator: "LONDONBUS",
date: "2017-07-25",
expected_departure_date: "2017-07-25",
aimed_departure_time: "09:18",
expected_departure_time: "09:18",
best_departure_estimate: "09:18",
source: "Countdown instant",
dir: "inbound",
id: "https://transportapi.com/v3/uk/bus/route/LONDONBUS/44/inbound/490013443E/2017-07-25/09:18/timetable.json?app_id=a111aa11&app_key=1a11111a1111aaa11a1a1111a11111a1",
operator_name: "London Buses"
},

If I use ‘https://transportapi.com/v3/uk/bus/stop/490013443E/live.json?app_id=a111aa11&app_key=1a11111a1111aaa11a1a1111a11111a1&group=no&nextbuses=no’

I get the following info (snippet):

{
mode: "bus",
line: "44",
line_name: "44",
direction: "Victoria",
operator: "TFL",
date: "2017-07-25",
expected_departure_date: "2017-07-25",
aimed_departure_time: "00:45",
expected_departure_time: "09:18",
best_departure_estimate: "09:18",
source: "Countdown instant",
dir: null,
id: null,
operator_name: null
},

Same bus, same info except the aimed_departure_time that is now 00:45. This means that when I calculate the delay, I get hundreds of minutes and the bus never drops out of the results.

So the issue appears to be with the ‘group=no’ URL variable.

Hopefully they will address this or at least get back to me. In the meantime I will see what I can do to remove these ghost buses.

nwootton

I’ve released an updated version that removes buses with a delay of more than 60 minutes from the results.

This is a hack until TransportAPI address the issues on their side. There is a side effect in that if 2 buses are delayed excessively, the module will only show 3 buses instead of the default 5.

Hopefully this will not make any difference to the majority of users.

Davepre

Thanks a lot Nick! This will surely solve the issue for me atleast!

Really appreciate you taking the time!
