Thanks Daniel.  It's just for routing costs.

Hey Jason,

our routing is fully customizable using profile written in Lua. For an
example see here:
https://github.com/Project-OSRM/osrm-backend/blob/master/profiles/car.lua
You should be able to base your custom profile on the ones that already
ship with OSRM.

Cheers,
Patrick

Re: [OSRM-talk] (no subject)

[Daniel Patterson]

Hi Jason,

  Depends on what you want to achieve.  Travel modes are used for a couple
of things:

1) For car routing, we primarily use two modes - normal, and ferry
mode.  This affects how the routing costs are calculated.
2) For the bike profile, the modes end up in the instructions -
sometimes we suggest that you walk your bike.

  Do you need to actually announce mode changes to the user, or do you just
need to identify different modes in order to calculate routing costs?

Hi,

I’m working on a custom routing app and need to apply some custom routing
rules in OSRM.  Is there a mechanism to add a mode of travel?  or would I
need to ‘reuse’ one of the existing modes?   For instance, if I wanted to
create routing rules for ATVs, could I create an “ATV" mode of travel in
 OSRM or would I need to use the normal vehicle routing and modify the
source data on my own instance?

Hey Romain,

Leaflet-Routing-Machine is a good reference for seeing how to query the
OSRM route with javascript from a browser:

https://github.com/perliedman/leaflet-routing-machine/blob/master/src/L.Routing.OSRM.js

They use corslite [1] to do the json querry.

 At some point, I have to run some tests (like thousands of tests) to
 extract some values from the JSON outputs (e.g. the total time). Now our
 problem is we tried several ways to do this, by sending HTTP GET requests
 to the running server and treat the returned response as JSON. But we tried
 with Javascript, jQuery and AngularJS, with functions like $resource.get,
 jQuery.getJSON $http.get or $http.jsonp and we never managed to get the
 returned response in a way that we could use it for further treatment in
 our script. Actually, we were able to send the requests to the server but
 the response is returned in the fom of an URL link which contains the JSON
 output in its body, not in the form of a variable in our Javascript that we
 could manipulate.

 As a matter of fact, we have two issues for this :
 - some of the functions we used (which are based on jsonp) added a
 callback parameter to the sent URL, so the request became invalid with
 'Query malformed at the position' errors
 - I've seen in the OSRM documentation that the JSON output is encoded with
 the Google polyline algorithm so it could be an invalid JSON for Javascript
 (we also observed errors like SyntaxError: JSON.parse: unexpected end of
 data at line 1 column 1 of the JSON data

 We essentially want to use the viaroute service, so our URL is something
 like that : htttp://localhost:5000/viaroute?loc=a,bloc=c,d with a,b, c
 and d random float numbers.

 Has anyone ever tried to run some customized tests on OSRM, with any Web
 language, and if so can he give me some tricks of how he succeeded to get
 the JSON ouptut where he wanted?

 To be clearer of how I proceeded in AngularJS, here the code of my app.js
 :
 var app = angular.module('clientOSRM', ['ngResource']);

 app.controller('appController', ['$scope','$http', 'appServices', function

 app.run(function ($rootScope) {

 var phase = $rootScope.$$phase;
 if (phase === '$apply' || phase === '$digest') {
 if (fn  (typeof(fn) === 'function')) {
 fn();
 }
 } else {
 this.$apply(fn);
 }
 };

 });

 and also the appServices.js code :
 app.factory('appServices', function ($resource) {

 return {
 osrm: $resource(, {}, {
 'get': {
 method: 'GET',
 params: {start: '@start', end: '@end'},
 isArray:true,
 url: 
 http://localhost:5000/viaroute?loc=:startloc=:endalt=falsegeometry=false
 
 }
 })
 };
 });

 In the getItinerary function in app.js, the error function (the 3rd
 parameter) is always triggered even with a HTTP status code '200 OK' of the
 request.

Hey Patrick,
Thanks for the help.

Sorry but I'm a little bit new with Javascript environment. I see that the
first link you sent me is contained in a full-working project. In order to
use the functionalities of the .js file, do I have to include the whole
project in some way, or can I re-use the single file on my side without any
extra-dependencies? Also, is the leaflet routing machine is useful to run
many tests on the OSRM server with random locations values each time?

Romain.

Hi,

If you want raw json data, then use a normal query like $http.get.

Second, you can pass compression=false to bypass the polyline encoding.

Guillaume

Thanks to all for your suggestions.

To Guillaume : I searched about the $http.get function and I wrote this
function to test if all goes well (I think I've tried it before) :
var getItinerary2=function(){
$http.get(
http://localhost:5000/viaroute?loc=47.3654647,0.6822917loc=47.3905003,0.6920979compression=false

.success(function(data, status, headers, config) {
console.log(data);
  }).
error(function(data, status, headers, config) {
console.log(error);
  });
};

Then I call it when I press Submit but the error function is triggered (the
browser console prints error).
Am I doing something wrong?

To Patrick : I will take a look at the JS file to find what could be
helpful. But, to be clear, what I'm trying to do is send a query to the
OSRM server and get back the response in the backend, in my script, not
directly in frontend, as I want to extract some information from the output.

To Emil : I saw the Cucumber Suite in the OSRM project but those are
precomputed tests, with known responses to the requests. In my case, I will
run tests on a large map (OSM file size : 122 Mo) with random locations
pairs inside the area.

 The OSRM project includes a set of cucumber tests that does a lot of

Ok, so after reading the Leaflet file, it seems to be an appropriate way to
send a HTTP request to the server and get the response back as variables I
could process in my script. Now I wonder how I could take this interesting
piece of code and adapt it to my AngularJS implementation.

 various support files that queries osrm are in features/support/

 Hello to all the OSRM community.

 I'm a french student who works on a university project, along with my
 supervisor and uses the open source project OSRM to achieve it.

 At some point, I have to run some tests (like thousands of tests) to
 extract some values from the JSON outputs (e.g. the total time). Now our
 problem is we tried several ways to do this, by sending HTTP GET requests
 to the running server and treat the returned response as JSON. But we tried
 with Javascript, jQuery and AngularJS, with functions like $resource.get,
 jQuery.getJSON $http.get or $http.jsonp and we never managed to get the
 returned response in a way that we could use it for further treatment in
 our script. Actually, we were able to send the requests to the server but
 the response is returned in the fom of an URL link which contains the JSON
 output in its body, not in the form of a variable in our Javascript that we
 could manipulate.

 As a matter of fact, we have two issues for this :
 - some of the functions we used (which are based on jsonp) added a
 callback parameter to the sent URL, so the request became invalid with
 'Query malformed at the position' errors
 - I've seen in the OSRM documentation that the JSON output is encoded
 with the Google polyline algorithm so it could be an invalid JSON for
 Javascript (we also observed errors like SyntaxError: JSON.parse:
 unexpected end of data at line 1 column 1 of the JSON data

 We essentially want to use the viaroute service, so our URL is something
 like that : htttp://localhost:5000/viaroute?loc=a,bloc=c,d with a,b,
 c and d random float numbers.

 Has anyone ever tried to run some customized tests on OSRM, with any Web
 language, and if so can he give me some tricks of how he succeeded to get
 the JSON ouptut where he wanted?

 To be clearer of how I proceeded in AngularJS, here the code of my app.js
 :
 var app = angular.module('clientOSRM', ['ngResource']);

 app.controller('appController', ['$scope','$http', 'appServices',
 function ($scope,$http, appServices) {
 //Initialisation de notre input, sa valeur sera stockée en instantané
 dans cette variable (ng-model)
 $scope.valueInput1 = 47.3654647,0.6822917;
 $scope.valueInput2 = 47.3905003,0.6920979;


 var getItineraryParams = function () {
 return {
 start: $scope.valueInput1,
 end: $scope.valueInput2
 //start: 47.3654647,0.6822917,
 //end: 47.3905003,0.6920979
 //start: a,b,
 //end: c,d
 }
 };

 //Une fonction accessible que dans ce controleur (mot clé var)
 var getItinerary = function () {
 appServices.osrm.get(getItineraryParams(),
 function (itinerary) {
 alert(Succes : +typeof itinerary);
 console.log(itinerary);
 },
 function (error) {
 alert(erreur : +typeof error+;
