Directions need to say "go straight onto road B"

[jidanni]

At an intersection, even if no left or right turn is involved, directions should still say "go straight onto road B", when departing road A.

To get from green marker to red marker, one takes these roads,

1. 仁愛路四段48巷
2. 四維路52巷19弄
3. 信義路四段99巷

Alas, due to no turns being involved,

only mention 1.

We're just relaying the instructions from the routing engines - if you have a problem with the instructions then you need to address it with those engines as we have no control over them.

This is the Graphhopper instructions for the query:

None of the engines mentions "19" in their instructions.

https://discuss.graphhopper.com/t/how-to-handle-when-street-name-changes-on-a-route/5528 mentions some url parameter to get all street names. I haven’t checked what options other routing engines are offering.

When added, the response includes a new detail section with all street names along the route.

Even the GraphHopper UI doesn't have an option to evaluate these additional street name details, so I think it's ok that we don't consider it either: https://graphhopper.com/maps/?point=25.036723%2C121.547048_25.036723%2C+121.547048&point=25.034351%2C121.547037_25.034351%2C+121.547037&profile=foot&layer=Omniscale

And the winner is...

Bing Maps also has all the

Road name changes to 信義路四段99巷

And even adds

The last intersection before your destination is 四维路66巷

If you reach 四維路76巷, you've gone too far

And it even tells you how to say the words.

Alas, no Share button.

Odd, other times what looks straight on the map is detected as a fork, so the bug of assuming it is the same road is avoided.
