Hi,

Is there any documentation on how to install this on FreeBSD 12?  I'm trying to

[OSRM-talk] OSRM API Address

[Kirtzic, Steven via OSRM-talk]

Hi,

I’m currently working on a project with OSRM and I’m moving it to another 
environment that is a lot more secure, so I need to request access for the OSRM 
API to be able to reach out to the external Internet. Can someone tell me what 
address(es)/site(s) I need to have made available for the API to retrieve OSM 
data correctly? I’ve looked through the documentation and source code and 
haven’t been able to find this info. For what it’s worth, I’m using the Docker 
image for the OSRM backend. Thanks

[OSRM-talk] Routing error on highway

[OpenStreetMap Brasil]

Greetings,

I have a car routing error, between two points on a highway: -26.4926,
-49.0021 and -26.4937, -49.0014.  I looked for errors in the OSM and found
nothing wrong.  Could anyone help find the problem?  In GraphHopper this
problem does not occur.

[OSRM-talk] File Location

[Vernon Chapman]

I am not sure if this is how to ask questions, but if not please provide the 
correct place to ask.

Where do I find the  output file from pre-processing? This is not my build of 
the OSRM, I am only trying to determine how much memory is needed to run the 
program after preprocessing.

I read somewhere that the amount of memory needed  is whatever the output file 
size from pre-processing is.

The builder is only using North Carolina and Georgia information, and that is 
all.

Thanks,
Vernon

[OSRM-talk] Comparing routes from different datasets

[Martin Schmidl]

Hi,

In a project of mine i am using OSM data from a city for 7 different years.
Recent data from 2020 acts as the reference. I want to see how different
changes in the data will affect the routing for quality reasons (e.g: If i
used data from 2014 today, will my route be better or worse?).

For this i am using OSRM on the 2020 data to get a reference route. I
planned to check if the same route is possible in the older datasets from
2014 to 2019 (if the same route isn't possible, i am computing the route to
the destination). I already tried to use some of the values from the
reference route, however many values (like node IDs or locations) change
over the different datasets and i can't really compare them to the original
reference route. Maybe someone has already done something similar and can
tell me what parameters were used from the routing result, i would really
appreciate that.

Best regards,
Martin

[OSRM-talk] Route with optimize waypoints

[Milan Hokr]

Hello

I am working on a route planning application and I would like to used your
REST API, but I need to know if your API allows you to plan route, so that
i enter start and end of the route,
waypoints of up to 80 in the request. The start and end of the route +
waypoints will be in Lat Lon format.
This planed route will be use for country The Czech Republic.

The result of the response should include:
a) Total distance traveled
b) Waypoints re-order so as to minimize travel costs.

I don't need to display a map and the number of requests does not exceed
500 per month.

Please send a price offer

Best regards Milan

[OSRM-talk] Routes not getting displayed in OSRM

[Sanghamitra Ghosh]

Hi,

I am trying to get routes in OSRM. The map is only displaying the "From"
and "To" point, but not displaying the actual route. I tried for areas like
Thailand, Sanjose, CostaRica. But the problem exists every where.

Can anyone please help?

One example of route that I was trying is given below:
>From Point:
13.774045, 100.512376
To Point:
13.836041, 100.505593

[OSRM-talk] inject request to OSRM

[evangelos spyrou]

Hi all,

We are in the middle of a project where we have to manually inject a
request to our local OSRM server. Essentially, we want to make a routing
request via the terminal (using a python script for example) from a
specific IP and update the frontend at that PC.

The question is how to inject a request to the OSRM server (not from the
frontend).

Thanks in advance.

Kind Regards

[OSRM-talk] OSRM backend

[Jetzer Laurent]

Hello,

In one of our project, we are using OSRM, but we only need the match service.
To save memory usage, is it possible to

  1.  import (osrm-extract) only the data needed for the match service?
  2.  start (osrm-routed) the match service only?

Kind regards

I think you are approaching this with the wrong expectation.

The map matching algorithm is not one that simply moves each of your
input points onto the output geometry and therefore has one output for
every input.

Instead, the map matching algorithm tries to answer the question: What
is a valid route on the routing graph that is most likely the basis of
this input GPS track?

This "most likely valid route" is then returned to you. It can have more
or fewer points than the input geometry; in fact matching input geometry
points to certain points on the output will be very difficult!

Bye
Frederik

[OSRM-talk] Running with Debug?

[Artur Bialecki]

Hello,

We're running older version of OSRM (5.6.0) and recently started getting 
segmentation faults during osrm-contract. I've recompiled the osrm backend with 
"cmake .. -DCMAKE_BUILD_TYPE=Debug" but I don't see any additional logging. Are 
there any other flags that need to be passed during building or to the process 
itself?

Thank you,

Artur.

[OSRM-talk] Re. Final Year Project Idea

[Anjula Paulus via OSRM-talk]

Hi,
My final idea is based on routing in road networks using reinforcement
learning to provide the best optimised route from a starting point to a
given destination.
This is based on the *Shortest Route Problem. *
The reinforcement agent is able to adapt in performing a high number of
iterations with their dynamically changing environment. This would be
beneficial when it comes to a dynamic road network which has updates on
edge weights based on traffic data etc. This is not the same with path
finding algorithms like dijkstra and A* algorithms which traverse the graph
each time a request is made.

*Second Assumption*
A novel graph preprocessing technique which could use  time dependent
contraction hierarchies with a customizable approach. This could help in
storing edge weights for a relevant time frame as well as update edge
weights based on abnormal weight changes due to blocks due to weather etc.
Where only edge weights will be updated due to unexpected scenarios
different from previous traffic data.

Please help by providing your valuable input on where these steps would
help in improving routing than using traditional algorithms and techniques.
This would really help me for my final year project.

Thank you in advance!

[OSRM-talk] Strange results from map matching

[Sasan Amini]

Dear all,
I am relatively new in using OSRM for map matching. I got my first results
but there are two issues that I can't understand. My data has 130 rows
(points) and in return, I get 150 points! I see a couple of duplicates
(some points are repeated 3 times after map matching). Additionally, 4
points are not map matched, even though it seems they are OK (screenshot
below). The algorithm handles the part where GPS is lost (the car is
driving in a tunnel) but 2 sets of 2 points are just not matched. Can
anyone help me with that?

Thanks,
Sasan
