• Highlights type numbers which cannot be used for routing - see below.
• Improved load and save options enabling backups of lines file.
• Set Selected routes / speeds to a certain value to allow for experimentation and see the effect in Basecamp:
  ie what happens if all my speeds were set to the same value etc
  Go Tools
• Option to backup original lines file

This makes a line routable and can be part of an address search.

Class refers to Length of Highway, not to it's physical properties.= (ie muddy, tarmac)

• For best results add the ' --remove-short-arcs ' option when running mkgmap
  It ensures some tight turnings have been removed.
  Even for hiking modes Garmin's algorithm avoids routes with any tight turnings
• It is important for routing to work well that most roads are class 0 and there are fewer and fewer roads in each of the higher classes.
• Giving all highways a 4 road_class not only affects routing , it also overloads the section reserved for boundary nodes.
• You can use mkgmap:road-class to override a class,ie increase or decrease it's value.
  
  ie : highway= trunk {set mkgmap-class=3}

• . It is an indication of how fast traffic on the road is. 0 is the slowest and 7 the fastest.
• This is not a speed limit and does not activate the maximum speed symbol on the newer Garmin car navigation systems.
• You can use mkgmap:road-speed to override a given speed
  highway=secondary & contstruction=* {set mkgmap-speed=3}
