cmd check messages about trips with "less than two stop_ids" #81

Closed rafapereirabr closed 2 years ago

rafapereirabr commented 2 years ago

cmd check is printing messages about several trip what have "less than two stop_ids", and several shapes with no departure_time. I don't know why we get these messages. I've check the GTFS feed and looks fine. Example below.

library(gtfs2emis)
library(gtfstools)
library(data.table)
library(ggplot2)
library(gtfs2gps)

# path to GTFS.zip file
gtfs_file <- system.file("extdata/irl_dub/irl_dub_gtfs.zip", package = "gtfs2emis")

# read GTFS
gtfs <- gtfstools::read_gtfs(gtfs_file)

# Keep Monday services GTFS
gtfs <- gtfstools::filter_by_weekday(gtfs, 
                                     weekday = c('saturday', 'sunday'), 
                                     keep = FALSE)

# check number of stops in trip_id
id <- "6030.2.60-15B-b12-1.359.O"
gtfs1 <- gtfstools::filter_by_trip_id(gtfs, trip_id =  id )
head(gtfs1$stops)
