Hi,
well - no pun intended - but that seems to be a quite egocentric
problem. ;-)
You may consider it a problem with a 2 min difference in a router
_estimation_ (about what time for the complete route?).
But a router has to consider
- a not so well biker
- biker with children
- a disabled person using cycle routes
Even only different velocities may differ in total time.
The router estimation will always be an average value - but who defines
the average?
I do not see a possibility for a _correct_ mapping for _everybody_ here.
Some mapper say a kerb is not a divider - but reality shows it _is_ a
divider for several users.
I would always optimise the mapping for users who are not able to
realise/see those routing optimisations - possible only for individuals.
OSM mapping is - and I suppose will always be - a compromise.
Greetings

Hi all,
I am having a problem at a place where my router is overestimating the
cycle time required for my journey, leading to bad results by default.
The problem is here: https://www.openstreetmap.org/node/4560492277
When I alight from a train with my bike and want to cycle north-west
after exiting the station at the specified node, in the real world I
would push my bike through the kerb onto the carriageway and start
riding. However, the mapping doesn't indicate that I can do so, so the
router think that I would need to either push the bike along the
pavement to the next junction, or use the signalised crossing to get
to the carriageway. This has resulted in it overestimating my bike
time by about 2 minutes.
What is the correct mapping here to indicate that I can push my bike
to the carriageway and mount it?
Thanks,
Michael
