We are following on from our previously loaded data of NYC bus delays, and from our simple Cubist regression fit. We know that we need to add in more predictors, and we have access to company level data. A warning to the faint-hearted: this post is essentially all data manipulation and joins. No pretty graphs, no conclusions. I am documenting the slog because the slog is required. We will move on to better things afterwards.

Preparation of company and route level data

We read in all of our data and take a look:

And we begin to engage in some 'exploratory' data cleaning. That is, we aren't quite yet sure what we are going to use, and what we aren't going to use. But we know dirt when we see it.

First we try to clean up iv_routes a little:

#iv_routes check_similar <- function(df){ df %>% mutate( diff= stringdist(Vendor_Affiliation, str_trunc(Vendor_Name,str_length(Vendor_Affiliation))), flag_company_same = ifelse(diff <= str_length(Vendor_Affiliation)/6, 1L, 0L), diff = NULL ) } iv_routes %>% check_similar() %>% filter(flag_company_same != 1) %>% distinct(Vendor_Name, Vendor_Affiliation) ## # A tibble: 12 x 2 ## Vendor_Name Vendor_Affiliation ## <chr> <chr> ## 1 EMPIRE STATE BUS CORP.

#cleaning that needs to be done prior to welding iv_cleaned <- iv_routes %>% mutate(Route_Start_Date = mdy(Route_Start_Date), Garage_City = tolower(Garage_City) ) %>% dplyr::rename( "Garage_Street_Address" = 'Garage _Street_Address', "Garage_XCoord" = "XCoordinates", "Garage_YCoord" = "YCoordinates" ) %>% check_similar() iv_cleaned %>% glimpse ## Observations: 42,114 ## Variables: 15 ## $ School_Year <chr> "2015-2016", "2015-2016", "2015-2016",... ## $ Route_Number <chr> "C911", "J499", "J500", "J501", "J502"... ## $ Service_Type <chr> "D2D", "D2D", "D2D", "D2D", "D2D", "D2... ## $ Vehicle_TypeDescription <chr> "Non-Wheelchair Accessible Alternative... ## $ Route_Start_Date <date> 2016-03-21, 2015-09-09, 2015-09-01, 2... ## $ Vendor_Code <chr> "VN", "RV", "HT", "HT", "HT", "HT", "H... ## $ Vendor_Name <chr> "VAN TRANS LLC (B2192)", "RELIANT TRAN... ## $ Vendor_Affiliation <chr> "VAN TRANS LLC (B2192)", "RELIANT TRAN... ## $ Garage_Street_Address <chr> "670 Hillside Road", "297 NORMAN AVENU... ## $ Garage_City <chr> "pelham manor", "brooklyn", "brooklyn"... ## $ Garage_State <chr> "NY", "NY", "NY", "NY", "NY", "NY", "N... ## $ Garage_Zip <int> 10803, 11222, 11224, 11224, 11224, 112... ## $ Garage_XCoord <dbl> 1034574, 1000787, 983439, 983439, 9834... ## $ Garage_YCoord <dbl> 265547.6, 204481.0, 148884.0, 148884.0... ## $ flag_company_same <int> 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,...

Next we join this to v_rbt, trying as best we can to figure out how they join, and to account for any observations which can't be joined as cleanly. 'School_Year' and 'Route_Number' appear to be our main joining headers, but this join leaves out 'OPT_Code' for some observations. These observations are not represented in the correct school year. We take a guess, and assign these an OPT_Code based only on the route, hoping that things haven't changed from year to year.

v_rbt %>% group_by(School_Year,Route_Number) %>% count %>% filter(n>1) ## # A tibble: 27,712 x 3 ## # Groups: School_Year, Route_Number [27,712] ## School_Year Route_Number n ## <chr> <chr> <int> ## 1 2015-2016 J510 2 ## 2 2015-2016 J690 2 ## 3 2015-2016 J700 2 ## 4 2015-2016 J701 2 ## 5 2015-2016 J702 2 ## 6 2015-2016 J703 2 ## 7 2015-2016 J704 2 ## 8 2015-2016 J705 2 ## 9 2015-2016 J706 2 ## 10 2015-2016 J707 2 ## # ... with 27,702 more rows

# There are 27712 School_Year, Route_Number combinations in v_rbt which appear more than once. Why is that? #Some year/route combinations have more than one OPT_Code. Why? #OPT_Code represents an organization in a specific location. Each Route/School_Year combination thus can serve multiple organizations in multiple locations. #This is going to cause us some problems later on, since we will have bus level data with multiple organizations attached. It will probably require some summary operations. v_joined <- iv_cleaned %>% left_join(v_rbt, by = c("School_Year", "Route_Number")) #62 observations have no OPT_code after this join. Check if the Route_Numbers can be matched alone iv_cleaned %>% anti_join(v_rbt, by = c("School_Year", "Route_Number")) %>% distinct(Route_Number) #59 routes ## # A tibble: 59 x 1 ## Route_Number ## <chr> ## 1 Z003 ## 2 T003 ## 3 T004 ## 4 Q8227 ## 5 T008 ## 6 T009 ## 7 Z001 ## 8 Z002 ## 9 Z004 ## 10 Z005 ## # ... with 49 more rows

#question: are all of these routes represented in the v_rbt, even if the year is wrong? iv_cleaned %>% anti_join(v_rbt, by = c("School_Year", "Route_Number")) %>% inner_join(v_rbt, by = "Route_Number") %>% distinct(Route_Number) #39 routes can be filled by ignoring year. Check. ## # A tibble: 39 x 1 ## Route_Number ## <chr> ## 1 Z003 ## 2 T004 ## 3 T008 ## 4 T009 ## 5 Z001 ## 6 Z002 ## 7 Z004 ## 8 Z005 ## 9 X2353 ## 10 X9353 ## # ... with 29 more rows

iv_cleaned %>% anti_join(v_rbt, by = "Route_Number") %>% distinct(Route_Number) #Yes, 20 routes left for which we have no OPT information. ## # A tibble: 20 x 1 ## Route_Number ## <chr> ## 1 T003 ## 2 Q8227 ## 3 X8304 ## 4 X8338 ## 5 X8339 ## 6 X8406 ## 7 X9874 ## 8 X9875 ## 9 X9881 ## 10 M8068 ## 11 M8246 ## 12 M9068 ## 13 M9246 ## 14 X8621 ## 15 X9621 ## 16 D002 ## 17 Q2455 ## 18 Q9455 ## 19 A002 ## 20 I001

Next we work on vi_transport, including looking into how unique OPT_Codes really are. We transform the vehicle descriptions into counts of the various kinds of passengers and attributes of each vehicle. This approach is a kind of 'type agnostic' approach, so that a new vehicle type can be predicted based on its properties, rather than just being a new predictor which the model cannot account for.

When I initially worked through this data, I tinkered with the pre-K data, ix_pvt, quite a lot. But in the end, it turned out that this data set only really existed as a way to join vehicle and staff metadata to the main data set via OPT_Code. The issue is that the school- and pre-K-level data don't share headers. So pulling, say, the garage information from the school-level data leaves NA values in the pre-K.

The driver and vehicle level data is, in the end, what I am after. The school and pre-K data is really just a way of attaching that metadata to the main data. Here is my cleaning work.

In my actual workflow, I wrote out all of my intermediate outputs as files that I could keep, and joined them in a separate workbook. In lieu of that process, the code below the fold simply renames some of the data sets that we have developed above. Apologies for any confusion: I promise that my project organization is a little less chaotic than this reporting markdown presentation.

Joining the data

After a lot of messing around, we are at the stage where we can join the company level staff and vehicle data onto the main data set. We also use the times to make variables that tell us how close to either rush hour we are.
