Re: Cycle Travel Question
It's the RAM that's the big thing. cycle.travel's core routing engine, OSRM, is very fast but also pretty memory-hungry. The latest core version of the code would need about 512GB RAM to calculate bike routing for the whole world. I use a very heavily customised version which is less memory-hungry, and which doesn't calculate all the regions at once - because you're not going to do Australia and the US in the same ride! But even then it's pretty demanding.

Re: Cycle Travel Question
What fun! How did you end up working with this project, Richard? What, briefly is your background? Or at least, such that you are comfortable sharing, of course

Re: Cycle Travel Question
c.t appears unwilling to route over the rather useful bridge at https://www.openstreetmap.org/way/27655273 (the driving on the alternative road is nasty, with wide SUVs hurtling around blind bends) and I can't figure out why. Can anyone spot the problem?

Re: Cycle Travel Question
Possibly that the bridge lacks any detail on surface - and cycle travel assumes that it is not good - is it paved like the rest of the track?

Re: Cycle Travel Question
It's probably this, plus I think Richard mentioned that CT gives a positive weighting to NCN and EV routes which may also help nudge Barsham Road into being preferred.BeardyWeirdy wrote: ↑24 Apr 2023, 3:04pm Possibly that the bridge lacks any detail on surface - and cycle travel assumes that it is not good - is it paved like the rest of the track?

Re: Cycle Travel Question
Yep, that's it - it's tagged as highway=path without any surface tag, so c.t guesses that it's unpaved. It will still route across it in standard mode, just not in paved-only mode.BeardyWeirdy wrote: ↑24 Apr 2023, 3:04pm Possibly that the bridge lacks any detail on surface - and cycle travel assumes that it is not good - is it paved like the rest of the track?

Oddly enough the first time I wrote any routing software was 30 years ago, for the Amstrad home computers. Someone did a video about it recently! https://www.youtube.com/watch?v=4DD9R6b5yEw

Starting to use cycle travel on my phone on my barbag. If it works I will probably get a top tube bag to house the phone.
Maybe me being thick but if I turn the route in the direction I am going in the map is upside down making it difficult to read villages and road names.
Can I turn it to the direction I am travelling in?
Thanks

Re: Cycle Travel Question
This will be a setting on your phone rather than in cycle.travel, I think.
Re: Cycle Travel Question
I’m waiting in the ferry queue so just tested mine as I couldn’t remember how it worked (as I last used it on Saturday!). You can swivel the view - 2 fingers on your iPhone to move the whole display. It default starts with north as up I think.

Re: Cycle Travel Question
Not entirely sure about the question, but on the iPhone app, you can use the map icon (top left) to choose one of these:
If you're a supporter and you have the extra map styles, bear in mind that only the cycle.travel and Wayfarer styles are capable of correctly rotating the village/street labels as you go along. The other maps (including Ordnance Survey and IGN) are all north-up. (This is because they're built differently - they're "raster" maps which are a predefined set of images, a bit like a printed map, whereas the cycle.travel and Wayfarer maps are "vector" maps which are drawn on your phone at the orientation you desire.)
- Centred - your current position stays at the centre of the screen
- Look ahead - your current position is at the bottom of the screen, and the map rotates to face the way you're going
- Perspective - like "look ahead" but the map is tilted, satnav-style

Thanks for your help.
Reading upside down is not my forte.
Also helpful on quick link phone holder.

Re: Cycle Travel Question
Just getting my head around a forthcoming Android App.
Is it possible to say at this stage:
(1) if it will work in a phone without a SIM
(2) which is the earliest version of Android it will work with
I'm contemplating this because I have an old Samsung phone which is (allegedly) waterproof which could make a fine SatNav.

Re: Cycle Travel Question
My challenge at the moment is to get a basic app out there and running! It will probably not have the offline maps capability from day 1, if that's what you mean about running SIM-free. I'm currently working to API level 31 which I think equates to Android 12.

Yes, offline maps is what I assume that I want.Richard Fairhurst wrote: ↑5 May 2023, 11:25pm My challenge at the moment is to get a basic app out there and running!

Equivalent to my Garmin Edge Explore which has maps, and I load a GPX (or similar) route onto it from cycle.travel or Komoot.
So ancient Android a non-starter initially.
I haven't quite worked out how to use cycle.travel on my phone running within a web browser to navigate.
Do I just tell it to centre on my GPS location when I've loaded my route and the little dot will follow the route?
Or is there some option to "navigate me along this route" which I haven't found yet?
