[OSRM-talk] Comparing OSRM with the car routing by OpenTripPlanner
Dear all, I am comparing two routing machines: openTriplanner and OSRM on the OSM map of Québec city (Canada) when looking for the best route by car. I get very puzzling differences, just running the default versions and configurations of OSRM and OTP for these coordinates: origin 46.793187,-71.183014 destination 46.770641,-71.285499 at 8am, mode car. The best route by OSRM is a 16km (18min) long, while the OTP recommandation is a 20km (24min) one. Google map recommends the 20km one (21min), the 16km road having a duration of 25 min. The 20km route goes along a highway, while the 16km one uses a primary road, I don't get why OSRM thinks this road is faster, while OTP points the opposite. Are you able to reproduce this discrepancy? Does that make sense to you?

[OSRM-talk] pont de Québec not in the routing steps of OSRM
Dear OSRMers, I use OSRM to determine through which bridge a car would cross the river St Laurent in Quebec city (Canada).

[OSRM-talk] Option to add buffer time for the trasnfer?
Dear OSRMers, Is there an option to add buffer time to transfer along a route? If I have such a pattern: bus > walk > bus I may want to increase the transfer time to take into account the possible delay of the bus. Is that possible?

[OSRM-talk] Weird behaviour of Turn-restriction in OSRM
Dear all, This is my first project with OSRM and OSM. I experience a very troubling behaviour of the turn restriction with osrm. I edit an osm map and want to remove any possible u-turn or left turn. If you look at this map, and look for the point #22 https://civiliagroupeconseil-my.sharepoint.com/:u:/g/personal/xprudent_civilia_ca/EXFdH132gY1Pk38xz54uN08BL87-xayY1WC7jLMTP9axHQ?e=UkCpL6 I give you here a zoom on the Rue Perras. You can see a u-turn is done on this street by osrm https://civiliagroupeconseil-my.sharepoint.com/:i:/g/personal/xprudent_civilia_ca/ETEmfFrTyIdGrWPwALg-jNMBLhFNB78b068x8ceNRqOw5g?e=YA8dOT But the rue Perras in the JOSM editor forbids left turns, as shown here https://civiliagroupeconseil-my.sharepoint.com/:u:/g/personal/xprudent_civilia_ca/Ef2rIh5MZ1VNnxrLxcTUkwgB1lJ0d_rTPcfBTH94I3BzCg?e=pd09Va and adding u-turns don't change anything. That is troubling as this procedure works on many intersections, but not for a couple of others ?!? Here is the OSM map I edit https://civiliagroupeconseil-my.sharepoint.com/:u:/g/personal/xprudent_civilia_ca/Ef2rIh5MZ1VNnxrLxcTUkwgB1lJ0d_rTPcfBTH94I3BzCg?e=StlweD Being a newbie, I must have overlooked something important.

Re: [OSRM-talk] U-turn penalty?
Dear all, As a follow-up on my question, for anyone facing the issue: my way out of this question of forbidding u-turns has been to get a local version of the OSM map and to edit it using JOSM. I then applied detailed constraints using the turnrestriction plugin. Good luck!

[OSRM-talk] U-turn penalty?
Hello, I want to forbid u-turns during the routing. I hence played with the u_turn_penalty parameter in profiles/car.lua u_turn_penalty = 20, then reconstructed the osrm objects using osrm-extract and osrm-contract. I tried values 0, 20, 240 and 1000. The routing clearly changed, but I keep on getting u-turns. For higher parameters I even get more u-turns. My understanding was that the higher the parameter, the less u-turn one should have.
