Errror in costructing network with setup_r5() function

[Ramon-88]

Hello and congrats for this amazing library! I'm using r5r to create origin-destination travel time matrices. Apparently I have a problem in building the network with setup_r5() as each time I try to build my graph, although I got the network.dat, an error message comes to verbose console output:

Summarizing builder config: build-config.json { "htmlAnnotations" : false, "maxHtmlAnnotationsPerFile" : 1000, "transit" : true, "useTransfersTxt" : false, "parentStopLinking" : false, "stationTransfers" : false, "subwayAccessTime" : 2.0, "streets" : true, "embedRouterConfig" : true, "areaVisibility" : false, "matchBusRoutesToStreets" : false, "fetchElevationUS" : false, "speeds" : { "units" : "mph", "values" : { "secondary" : 35, "tertiary_link" : 25, "primary_link" : 25, "tertiary" : 25, "living_street" : 5, "motorway_link" : 35, "trunk" : 55, "secondary_link" : 25, "motorway" : 65, "trunk_link" : 35, "primary" : 45 }, "defaultSpeed" : 25 }, "staticBikeRental" : false, "staticParkAndRide" : true, "staticBikeParkAndRide" : false, "bikeRentalFile" : null, "analysisFareCalculator" : null }

[main] ERROR com.conveyal.r5.streets.StreetLayer - Continuing to load but ignoring generalized costs due to exception: java.lang.RuntimeException: All ways are expected to have generalized cost tags. Missing: slope_1:forward

I allocated more memory before executing library(r5r) by using options(java.parameters = '-Xmx2G') so I'm not sure why I got this error, I downloaded .pbf file from hot export tool website and BBBike.org website and also I tried wirh both small and big files but apparently nothing changed.

Do you have any idea why this happens? And mostly this error can affect the calculation of travel time distances?

Thanks in advance

could you please run sessionInfo() on your R session and paste the output in a comment below?

[Ramon-88]

Yes sure and thanks for replying me:

For completeness I also past a warning message that I got from the console, just below the error message. With respect to this I searched online and apparently this shouldn't be problematic:

could you please run the example below to see if the problem persists?

Start fresh R session

# allocate RAM memory to Java
options(java.parameters = "-Xmx2G")

# 1) build transport network, pointing to the path where OSM and GTFS data are stored
library(r5r)
path <- system.file("extdata/poa", package = "r5r")
r5r_core <- setup_r5(data_path = path, verbose = FALSE)

# 2) load origin/destination points and set arguments
points <- read.csv(system.file("extdata/poa/poa_hexgrid.csv", package = "r5r"))
mode <- c("WALK", "TRANSIT")
max_walk_time <- 30   # minutes
max_trip_duration <- 60 # minutes
departure_datetime <- as.POSIXct("13-05-2019 14:00:00",
                                 format = "%d-%m-%Y %H:%M:%S")

# 3.1) calculate a travel time matrix
ttm <- travel_time_matrix(r5r_core = r5r_core,
                          origins = points,
                          destinations = points,
                          mode = mode,
                          departure_datetime = departure_datetime,
                          max_walk_time = max_walk_time,
                          max_trip_duration = max_trip_duration)

Starting a fresh R session and running your first part of code:

# allocate RAM memory to Java options(java.parameters = "-Xmx2G")

# 1) build transport network, pointing to the path where OSM and GTFS data are stored library(r5r) path <- system.file("extdata/poa", package = "r5r") r5r_core <- setup_r5(data_path = path, verbose = FALSE)

I got this result:

What version of Java do you have installed on your comuter? Please bear in mind that you need to have Java SE Development Kit 11 installed on your computer to use r5r. The JDK v11.0.10 is freely available from the options below:

• OpenJDK
• Oracle

[Ramon-88]

I followed all the instructions reported in the section "Installation" so I already downloaded the suggested version of Java from the link you sent me now. Anyway by running rJava::.jcall("java.lang.System", "S", "getProperty", "java.version") it returns the following version: "11.0.16.1"

[rafapereirabr]

please try running r5r::download_r5(force_update = T) and then try running the code of the example

[Ramon-88]

I just did it and unfortunately it returns me the same error/warnings messages as before

this is probably the problem. Please install JDK v11.0.10 and try again

[Ramon-88]

I tried again by using first JDK v11.0.10 and then JDK v11 downloaded here: https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html but unfortunately nothing changed. I was thinking to use another laptop to try if it works or not as maybe there is something on my laptop that is affecting the process.

[rafapereirabr]

have you uninstalled java 11.0.16.1 ? Please sure to check what Java version your R is picking up.

run

rJava::.jinit()
rJava::.jcall("java.lang.System", "S", "getProperty", "java.version")

the output should be "11.0.10"

[Ramon-88]

I did what you suggested. To be sure I uninstalled java 11.0.16.1 and then restarted windows before doing the new installation after that I checked and got this output "11.0.10", but still when I run the example I got the same error/warnings. Just for curiosity I tried to run also this example (https://www.urbandemographics.org/post/r5r-fast-multimodal-transport-routing-in-r/) and despite I got the same problems, checking the first lines of the output head(ttm) they corresponded to the results I got. I was just wondering if this error/results really affects the creation of the network and so the analysis itself.

[rafapereirabr]

Hi @Ramon-88 . R5 does throw some error/warnings messages which, as a rule, are not critical to the creation of the network. If you're getting the same results from the example you mentioned, then everything is working fine. Closing this issue for now.

[Ramon-88]

Got it, thanks for your availability!
