Re: ENDURO: motorbike riding on unpaved und bad tracks which are allowed

[Poutnik]

You have too mild, leaking access restrictions where it was obvious the
access was only for foot or bikes.
I suggest to rebuild it, as allowed bike or foot access does not mean
allowed motorbike access.

You should to follow the motor vehicle access chain.
It would follow the access with decreasing priority
access for motorbikes
then for motor vehicles
then for vehicles
then general/default access


assign defaultaccess =ifaccess=private|no|agricultural
then 0 else 1

assign vehicleaccess = if vehicle=private|no|agricultural
then 0 else if vehicle= then
defaultaccess else 1

assign motor_vehicleaccess = if motor_vehicle=private|no|agricultural
then 0 else if motor_vehicle= then
vehicleaccesselse 1

assign motorcycleaccess = if motorcycle=private|no|agricultural
then 0 else if motorcycle= then
motor_vehicleaccesselse 1

assign accesspenalty = switch motorcycleaccess0 9999

Some typos, I have rearranged the code

[Poutnik]

An equivalent, but better as faster is( placed in way context )

assign motorcycleaccess =
if motorcycle=private|no|agricultural then 0

else if not motorcycle= then 1
else if motor_vehicle=private|no|agricultural then 0
else if not motor_vehicle= then 1
else if vehicle=private|no|agricultural then 0
else if not vehicle= then 1
else if access=private|no|agricultural then 0
else 1

assign accesspenalty = if motorcycleaccess then 0 else 10000

Hi Poutnik, I would need to know if there is a profile for enduro motorcycles, or wich is the best profile to use with the last one.. thanks

[Johannes Millinallinger]

Hello guys, 

I'm also interested in using brouter for adventure motorcycling, e.g. long-distance travelling on lightweight offroad motorcycles. For now i guess the best idea is just to use one of the bicycle profiles and tweak them to our specifc needs, such as: 

Ignoring the steepness factors relevant for bicycles

Avoiding populated areas if possible due to the noise issue and also since towns and settlements slow you down on a motorcycle

Including an option to avoid roads where motor vehicle access is forbidden

I don't have any experience in coding but I will give it a try. If anyone has any tips for me, those are very welcome. 

Best, 

Joe

Hallo Joe

What you want to do is not coding, but configuring. First read and try to understand an example for bike, for car and the one above. Next start from one and merge useful aspects from the other ones. Test each change with the brouter web-interface: http://brouter.de/brouter-web.

I would not ignore the steepness factor. If you use negative weights, than you prefer steep routes before flat ones, which means generally more fun riding a dirt bike.

Good luck, Stephan
