For which purpose would the two highways be reassembled? Split highways may be reassembled when you're not interested in the attributes that do change between them. For example when you want to reassemble the portions of the same road with the same class and name together but aren't

Then it is up to the driver to follow the rules, and allow the router to re-plan. Mapping to this level is really a non-starter, mapping every solid line is not going to happen. On rural trunk roads they are just frequent, ass they are used to prevent overtaking on bends, and there are a lot

2012/8/19 Florian Lohoff f...@zz.de: The turn happens on a node and not on a line. +1, that is true, but each of these nodes is also part of at least 2 highways, and this is not too difficult to evaluate so common turn_restrictions could be created automatically (on a local copy) for routing.
