Strange routing for bicycles
  • Navigator Free is one of very few applications that performs offline routing on open streetmap maps on PC and PDA. Thats what I was looking for, especially for bicycle driving.
    But the routing is sometimes very strange - a huge loop way is generated. One example is: start in 'Bargteheide' (germany) dest in 'Stade'.
    I have used version 11.0.35 (PC version on Win7, 11.0.33 PDA Version in HP IPAQ travel companion). Vehicle=Bicycle, routing=fastest.
    Also if you choose 'shortest' routing you get strange results.
    Thanks for help!

  • Hello Tazacorte,
    I would like to repeat your routing, but for that I need exact coordinates of your departure and destination. Can you send me your routing_points.xml file?
    thanks

  • Bicycle driving is very buggy. Often it is not possible to finde a route.

    Start:
    51°33´32.9"N   6°59´30.9"
    Destination:
    51°44´33.2"N  7°11´59.0"

    Navigator free v. 11.0.35 is not able to find a route for a bicycle. Wenn this error occurs, I can change to any other vehicle, there is no possibility to find a route. First I must end the programm, start new and then Navigator is able to find a route with this new vehicle (not with the biycle).
    I made a "new bicycle" from a pedestrian and changed the velocities. Now Navigator finds the route, but he ignores the closed streets, I told him.

    Another bug:
    If I will drive from any position to Germany - Winterberg, Hochsauerlandkreis - town centre, the program crashes just after "navigate" or "Show on Map". When I disable in menu - settings - map - select regions "all imports", then the program does not crash.
    But now I have no cameralight and -speed.
  • @ MDDIO, I tried your example on PC and it found a reasonable route without motorways. When I reduced the number of expanded links (settings.xml, section RTG, parameter limit_expansion) from 100000 (default on PC) to 10000 (default on PDA/PND) it failed to find the route. The reason is that there is no suitable "transit network" which is for cars motorways. Can you increase the value on your PND and try it?

    ad import - do you have also your own import? Can you send me log after the crash?

    @Tazacorte - I tried your points from email and the cause is the same. In your case it finds "transit network" but it is too far and unsuitable for a bike. If you increase the limit to 100000 the route will be 65km long and use boat ferry.

    does it help? thanks

  • @Martin:

    Thank You, modifying the limit_expansion to 100000 is the right way to solve the first Problem. I got a nice route for my bicycle and Navigator considers the closed Roads I told him.

    No, I have no own imports, only the standard imports for cameralight and cameraspeed. I use maps for the whole world, but only europe and imports enabled.

  • Hello,

    OK - increasing the limit_expansion helps! I get in most cases better routes now.
    What does this parameter do? I have set it to 10000000. My fealing is that further increase does not have any effect? What is the disadvantage of bigger values?
    I also get better results on my modified "bicycle2" configuration, where I changed the road priority. I set minor roads to higher priority. With this you can prevent routing over bigger roads.

    But - with increasing distance the routing becomes strange again. OK - I do not need bicycle routes with more than 200km very often, but it is even more important to get good results for this cases. Here is an example with this behavior:

    <departure><lat>193388440 <lon>36830650
    <destination><lat>189648523 <lon>28326933


    regards
    Dirk
  • Hoping the Bicycle Routing will be sometimes better without changing configuration files.
    For a 20 km toure it works good. The Algorithm need a Autobahn. If i am planning a car-route without autobahn, i get the sanme bad results. For far bicycle routing works only the pedestrian mode.

    Hoping in navigator 13 is this problem solved.
  • Hi Matthias,
    what version/platform do you have? I checked both PC and Android and truck_restrictions.xml/vehicle_profiles.xml have set expansion limit to 100000. Your problem is caused by "transit network", which is not used in pedestrian mode at all.
  • I have 12.3 (The newest version of navigator free) and windows XP, Windows 7 Starter Edition and Windows 8.1.
    For 500km long distance between 2 points, the pedestrian mode need alot of CPU-Time.

    Thank you very much for this information. The "transit network" need maybe the motorways.
    I have made a new vehicle profile for bicycle using the pedestrian-mode and setting just the speed of streets and vehicle higher, and it works.

    sorry i have a german version and dont know the right english names of the features.

Howdy, Stranger!
