rnet is huge, slowing down pct-shiny about pct-scripts HOT 11 CLOSED

Only issue I see - could be seen as too simplified when only 5% of vertices are retained. On the other hand it seems to be faster. Will try for a larger area and see. @nikolai-b and @JDWoodcock could I get your view on this level of simplification: too much?

hi so the issue here is that it doesn't exactly follow the road network? If so then that is probably okay -as road network is not always exact route anyway. Certainly if large speed up then yes.

@JDWoodcock yes that's the issue - and agreed it's not a big problem.

looking at tunbridge wells, Kent I find it not loading too slowly but sometimes the match to the network is poor, e.g. Landsdowne road- see attached.

I also wonder if we should have some kind of hour glass thing to show people when it is still loading? It is easy to think it is loaded and wrong when it hasn't loaded yet.

Hi @JDWoodcock please be precise about what you would like to see changed. Less aggressive simplification for Kent and everywhere? Would the max value of 50% not solve this? I think not matching the route network could be an advantage: these are only rough 'desire lines'.

@Robinlovelace I suggest we bring a few examples to the meeting to discuss route network- tighter snapping to the route network is desirable but clearly trade-offs are needed.

We are simplifying rnet more now

@nikolai-b can I check if simplifying means a less good fit with the route network? If so please can we know when it is done so we can check if it is okay.

from pct-scripts.

It's done for kent - we can increase or decrease the level of simplification @JDWoodcock your understanding of it seems correct

from pct-scripts.

Currently on my computer (i5 8gb) it is running nicely and I think simplification level is okay for Kent. Quickly goes to 50% of route network- probably could see higher % but want to see how it works for a region with more flows first- let me know when a big region is ready to test.
