The road(highway) is directly derived from the OSM highway hierarchy. It's the most complicated ones in Map Suite World Streets. The type of road is column “class”.Some road has a column called 'oneway', which is used to access restriction on the roads as appropriate(when the way can only be used in one direction). Some road examples: motorway, secondary, track, motorway_link, cycleway, etc. See more examples below.
