# or trimming of the profile according to biker preferencing without need of profile deep insight
|
|
#
|
|
# Positive values progessively promote/penalize roads in favour of MTB riding.
|
|
|
|
# Negative value has the opposite effect, preferring mainroads and penalizing unpaved roads.
|
|
# This effect is somewhat similar to iswet=1 ( *) wet weather mode ),
|
|
# but does not distinguish particular road classes / surfaces / smoothness,
|
|
# aside of mentioned schema below.
|
|
|
|
# The calculated values below is added to the costfactor.
|
|
|
|
# + MTB_factor for main roads (tertiaries and better),
|
|
# + 0.33 * MTB_factor for paved roads,
|
|
# - 0.33 * MTB_factor for not paved/not unpaved roads,
|
|
# - MTB_factor * ( 1 + 0.33 * smoothnesspenalty ) for unpaved roads. - at MTB_factor 3.0 smootheness is ignored
|
|
#
|
|
# Default is 0.0 = no effect.
|
|
# Recommended -0.5 - +1.0
|
|
# Reasonable -2.0 .. +3.0,
|
|
#
|
|
# Final costfactor is kept >= 1 for final costfacto values.

|
# 2014-10-10 v1.1 - changed hiking route preference logic
|
|
# 1.2 - fixed preference counting bug
|
|
# 2014-10-11 1.3 - adding foot route to hiking routes,
|
|
# fixed ferry cost to respect initial cost triggerring.
|
|
# added bikeaccess, added shortest way mode, code cleanup
|
|
# 2014-10-12: v1.4 - involving turncosts and way/node initial costs as orientation/decision penalties,
|
|
# but turning them off for sticking to hiking routes as extra preference,
|
|
# tweaking cost preferences
|
|
# 2014-10-13 v1.5
|
|
# redesigned route preference policy - turncost turned off even for nonsticky but preferred hiking routes
|
|
# cost tweaking.
|
|
# removed uniform cost=1 for sticky hiking routes, to distinguish quality
|
|
# giving penalty 1 for non hiking routes at sticky hiking routes.
|
|
# used not round costs to often trigger initial cost calculation
|
|
#v1.51 - bugfix of redundant routing penalty
|
|
#v 1.6 - initialcost penalty only for sticking routes, decreased way penalties for preferring routes
|
|
# 31/5/2015 v 1.7 ALFA + sac_scale + sac_scale_limit implemented
|
|
# 10/6/2015 v1.7.1 ALFA * sac_scale improved
|
|
# + MTB scale integrated to SAC scale
|
|
# + sac_scale_preferred implemented, with progressive penalizing for SAC <> SAC preferred
|
|
# 10/6/2015 v1.7.2 BETA ! Fixed general way access penalties
|
|
# 15/6/2015 v1.7.3 BETA * SAC-MTB scale integration reevaluated, increased MTB scale penalty
|
|
# * MTB scale penalty used as fallback if no SAC rating
|
|
# 16/6/2015 v1.7.4 ALFA * Optimized SAC logic
|
|
# 17/6/2015 v1.7.5 BETA + Track penalty system
|
|
# 20/6/2015 v1.7.6 RELEASE * Modified and simplified route preferencing
|
|
# 01/12/2015 v1.8.1 ALFA +ported MTB_factor from bicycle Trekking template, renamed for hiking context to Offroad_factor
|
|
# 02/4/2016 v1.8.2 ALFA +implemented path preference factor , try 20.0. Default 0.0 has no effect
|
|
# 3/5/2016 v1.8.3 BETA +implemented navigation hint support
|
|
# 7/5/2016 v1.8.4 RELEASE +implemented navigation hint support ftom BRouter 1.4
|
|
# 10/5/2016 v1.8.6 BETA * decreased turnInstructionCatchingRange from default 40 to 20
|
|
# 18/5/2016 v1.8.7 BETA ! Fixed down/uphillcostfactors for shortest_way - to be really shortest
