Question 1

When tagging a Shared Bike Trail at a junction, what is the correct approach?

Accepted Answer

Create a polygon covering the whole section of the neighboring lane where vehicles drive, considering traffic direction, but do not tag inside the junction.

Answer

Change only the polygon type ID without adjusting the polygon shape.

Answer

Tag the entire junction as a Shared Bike Trail.

Answer

Tag only the visible portion of the Bike Trail near the junction.

Question 2

You encounter a narrow one-way road with a bike marking but no separate lane for bikes. What is the correct annotation for this case?

Accepted Answer

Mark it as a shared bike trail since it is a one-way road with no neighboring lane

Answer

Tag the entire road as pedestrian-only

Answer

Do not tag it as a bike trail due to limited space

Answer

Mark it as a standard bike trail

Question 3

You encounter a lane that is shared between bikes and buses, with a solid line separating it from the adjacent car lane. Private vehicles are not allowed in this lane. How should this be annotated?

Accepted Answer

As a shared bike, since it is used by both bikes and buses

Answer

As a dedicated bus lane

Answer

As a bike trail, and mark the adjacent car lane as “neighbor: bike trail on left”

Answer

Do not tag the lane because private vehicles are restricted

Question 4

You come across a lane designated as a bike trail, but cars occasionally cross it to access private properties or parking areas. There is no continuous vehicle traffic along the lane. How should this situation be annotated?

Accepted Answer

As a bike trail, and also mark the neighboring lane where cars actively drive.

Answer

As a shared bike lane, since vehicles sometimes use it.

Answer

As a parking lane, because cars use it to park.

Answer

Do not annotate it due to mixed usage.

Answer

true

Question 6

Should we mark these cases as neighbor lane for bike trail?

Accepted Answer

false

Answer

true

Question 7

Answer

true

Question 9

You encounter a lane that is used by buses and bicycles, but private vehicles are not allowed. Should this lane be annotated as a shared bike lane or as a neighboring bike trail?

Accepted Answer

Shared bike lane, since bikes share the lane with buses

Answer

Do not tag it, as bikes and buses use the lane

Answer

Only tag it if private cars are allowed

Answer

Neighboring bike trail, because private cars are not allowed

Question 10

Should parking lanes be considered when tagging a neighbor lane for a bike trail?

Accepted Answer

No, parking lanes should not be considered as neighbor

Answer

Yes, if cars are occasionally moving in or out

Answer

Only if the parking lane is actively used

Answer

Yes, if they are adjacent to the bike trail

Question 11

Should we mark a shared bike lane within an intersection even if there are no specific bike indications, as long as it's a drivable area for vehicles?

Accepted Answer

Yes, mark it to ensure continuity for bike routing

Answer

Yes, but only if it is a major intersection

Answer

No, only mark if bike signs or markings are visible

Answer

No, intersections are not marked for bike lanes

Question 12

When tagging roundabouts (RA), should we mark them as shared bike areas if there’s no solid bike trail marking?

Accepted Answer

No, only mark roundabouts based on the presence of DPs indicating a bike trail

Answer

No, roundabouts are never marked for bike-related annotations

Answer

Yes, but only if the roundabout is large

Answer

Yes, always mark roundabouts as shared bike areas if no solid bike trail is present

Question 13

Should alley roads or private parking areas that are not displayed as streets on Google Maps be included in shared bike lane tagging?

Accepted Answer

No, exclude them from shared bike marking

Answer

Only mark them if a bike trail sign is present

Answer

Yes, as long as they are drivable by vehicles

Answer

Yes, but only if bikes are frequently seen there

Question 14

In a scenario where a bike trail ends before a junction and there are no explicit markings within the junction itself, but it appears that bikes would still pass through — how should this be marked?

Accepted Answer

Continue the bike trail through the junction if it’s likely that bikes will pass there.

Answer

Convert the bike trail to a pedestrian lane.

Answer

Mark the junction as a parking area.

Answer

Do not mark anything in the junction unless there is a clear marking.

Question 15

If all lanes approaching a junction are marked as shared bike lanes, but there are no shared bike indicators within the junction itself, should the junction still be marked as shared bike?

Accepted Answer

No, shared bike markings should stop at the stop line if there are no indicators within the junction.

Answer

Only mark the junction if it also serves as a pedestrian crossing.

Answer

Yes, to maintain continuity with the approaching shared bike lanes.

Answer

Mark the junction as a bike trail instead.

Question 16

You encounter a roundabout where the 2024 Google Maps imagery shows bike lane markings, but MM imagery and 2022 Google Maps imagery do not. Which approach should you take when deciding how to annotate this area?

Accepted Answer

Follow the most recent Google Maps imagery (2024) and mark the entire roundabout as a Shared Bike area.

Answer

Use the 2022 imagery since it's closer to MM.

Answer

Do not mark the roundabout at all unless both MM and GM show markings.

Answer

Ignore all imagery and mark based on assumptions.

Question 17

You encounter a road marking labeled "escola" that visually resembles a bike lane. How should this case be annotated?

Accepted Answer

Consider it as a Shared Bike lane and verify that it is marked correctly.

Answer

Mark it as a school zone and ignore any bike-related context.

Answer

Do not mark it, as "escola" does not refer to bikes.

Answer

Mark it only if there is a solid bike lane marking.

Question 18

You encounter a road marking that appears to depict a motorcycle. How should you proceed with the annotation?

Accepted Answer

Treat the motorcycle as a bicycle and proceed with marking accordingly while we wait for new polygon.

Answer

Wait for a new polygon before doing anything.

Answer

Ignore the marking since it's not a bicycle.

Answer

Mark it only if there's also a bicycle symbol present.

Question 19

A bike stop is located beside a dedicated bike trail, and the area is separated from the vehicle lane using plastic poles (not concrete). According to the bike trail definition, how should this be tagged?

Accepted Answer

Tag it as a bike trail (neighbor), since the stop is intended for bike trail users and plastic poles do not invalidate the trail classification.

Answer

Tag it as a shared bike lane because there is no concrete separation.

Answer

Do not tag it at all because the physical separator is unclear.

Answer

Tag it as a vehicle lane with a bike stop.
