osrmRoute with via points about osrm HOT 13 CLOSED

This is not possible in osrm yet. OSRM server allow to pass several points in the route service.

Thanks @rCarto.

I have two questions, and I would appreciate if you can get me answers to the best of your knowledge.

Is it possible to plot road routes which are on osrm using leaflet or mapview?
How do I extend the number of co-ordinates to be routed over 100 points on osrm

from osrm.

1. A simple example to plot routes with mapview:

library(osrm)
# Travel path between points between points - output a SpatialLinesDataFrame
route <- osrmRoute(src = c("A", 13.43853, 52.47728),
                   dst = c("B", 13.32247, 52.48882),
                   sp = TRUE, overview = "full")
library(mapview)
mapview(route)

Displaying the underlying OSRM road network is not possible. You can have a look at the osmdata package.

2. Getting routes with via points implies modifying the code of the osrmRoute() function. I'll have a look into that feature as soon as possible.

@rCarto I had plotted the routes of some locations. The maximum number of locations allowed for routing using the OSRM is 100 coordinate points.

Kindly let me know if you get some findings on expanding this restriction.
Thanks

I don't know how the R studio module works. If it's making requests to the OSRM demo server at https://router.project-osrm.org/, then you'll need to learn how to install and build OSRM separately, then run osrm-routed with the option I posted above.

@rCarto What do you think of this?
I think there's a way here. Do you think you can make this happen?

from osrm.

The osrm package use an OSRM server. The default server has limitations. You can run your own instance of OSRM server (via docker) with the described options to get rid of the limitations and make osrm package use your server.

That’s why I reached out to you @rCarto.
How can I get this done using R

from osrm.

As stated in the documentation, to change the OSRM server, change the osrm.server option:

options(osrm.server = "http://address.of.the.server/")

from osrm.

Thanks @rCarto I got osrm to work using the local host. I can now use the osrmTablefor more than 100 coordinate points but I have concerns about osrmTrip because I still get errors of The OSRM server returned an error: Error: TooBig Too many trip coordinates when I try to use in for analysis greater than 100 coordinates.
I need help please.

from osrm.

Hmm, there may be an other option to set on the server side. I would search on the OSRM engine documentation.

from osrm.

I have set it already. Thanks

For those who would like to get solution from my experience.
Here's how I got it done.
osrm-routed --max-trip-size X map.xml.osrm where X is the size you'd like to use.

version 3.3.2 should address the original question
