# changelog:
# *** Based on Trekking profile, added flag driven customizations
# Hiking Version 1.6 ALFA
# 2014-10-10 (c) Poutnik
# Route_foot related hints were improved with usage of Hiking.brf from below and by Arndt comment
# http://pastebin.com/YLpkGVD4
# http://forum.openstreetmap.org/viewtopic.php?pid=447507#p447507
#
# 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

# ****) Offroad_factor ( ported MTB_factor from bicycle Trekking profile
#############################################################################################
#
# MTB_factor tweaks/trims MTB approach of the profile by preferring/penalizing in progressive order
# nonpaved - preferred
# not paved - little preferred
# paved - little penalized
# mainroads - penalized
#
# MTB_factor can be used for one-time tweaking of routing profile for particular trip,
# 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.

# Feature is / + added / - removed / * changed / ! fixed
# Hiking Version 1.6 ALFA
# 2014-10-10 (c) Poutnik
# Route_foot related hints were improved with usage of Hiking.brf from below and by Arndt comment
# http://pastebin.com/YLpkGVD4
# http://forum.openstreetmap.org/viewtopic.php?pid=447507#p447507
#
# 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
