Issue 10: Google Maps need to add bikeable links so that Cycling Directions follow recommended routes
Summary: Google Maps Cycling Directions are sometimes inaccurate, sub-optimal or impossible to manually adjust because critical bikeable connecting links - such as shared walking/cycling paths - do not exist or are not marked as bikeable in its Cycling layer.The result is that its Cycling Directions do not show the precise route link (typically off-road) recommended or popular with cyclists and default instead to roads that follow a long way round or are less safe or convenient.
In some cases, the Cycling layer does include the bikeable link, but it is drawn on-road when it is typically off-road. This often looks like the cyclist will need to travel the wrong way down a road.
Details:
1. When connecting links are missing Google Cycling Directions follow non-preferred routes and cannot be manually adjusted to follow the recommended route
Below is a common example of a missing shared path running along a railway line. This prevents the most direct and preferred cycling and walking routes from showing up in Google Maps.
The existence of the shared path (with pedestrian and bike symbols) is clear from Google Maps Street View:
That this shared path is a recommended bike route is confirmed by the City of Moonee Valley's document: Improve walking and cycling along the Craigieburn Rail Corridor (PDF)
Most of the legally-bikeable missing links in Google Maps are shared paths (aka mixed use paths), often running along non-road routes (rail corridors, laneways, open/green space, etc). It's important for Google to cover walking and cycling routes with the same comprehensiveness as it applies to motor vehicles.
2. Informal shortcuts that are the dominant de facto route should be added to the Cycling layer and Cycling Directions
While legalities may prevent many informal shotcuts or routes from being added, some are de facto routes (even if temporary) and high value enough to be added given the safety or inconvenience issues of the alternatives.
A great example of a popular, high-value shortcut is the route through a business park from Childers St to Lloyd St in West Melbourne.
