successfully. There, 'network:type=node_network' describes the type of<br>
signposting. <br></blockquote><div><br></div><div>No, it doesn't! It describes the type of network using labeled Nodes and Node2Node connection routes to guide the walker, cyclist, horse rider etc through the area along a prescribed list of labeled Nodes. Each labeled Node points with labeled arrows to the adjacent Nodes, so the user just needs to follow the arrow to the next Node on the list (or node strip). Operators tend to vary a lot in how the signposting is done, but that is superficial; it's the guidance system that counts, and that is what the tag is for. </div><div>The tag network:type=node_network sets the Node2Node routes and the labeled Nodes apart from other routes and routing systems, and is used by data users for specific rendering, planners and network maintenance tools. It does not imply a specific implementation, a specific design or type of labeling or signposting; that is up to the operator. In some regions, the Node network signage is integrated with other types of signage into one overall signposting design. </div><div><br></div><div>The network:type key allows for other values for other specific planning & guidance systems. I think destination based planning and guidance is regular routing and navigation, and in itself does not need any special tagging. </div><div><br></div><div>I am fine with tagging <transport>_network for national, regional and local network plans. Most of those I see as road preference systems, aimed at channeling traffic. I would translate that into some kind of quality indicator, to be used as a weight indicator for routing. If it is a collection of predesigned routes, typically with route labels and indication of an operator, that's where the <transport_network=* can be applied, I think, even though I personally don't really care whose route it is if I'm on the road. </div><div><br></div><div>But is it worth it to break down the road system into pieces between every guidepost,create route relations for all the pieces, and labeling all these chunks with a *_network=* value? It's a lot of work, it's a lot of never-ending maintenance, and what does it actually achieve? </div></div></div>
