# How to query a relation (route) for details?

 1 Is there a way to get the total distance and distance of the different types of ways that make up a relation such as this one? https://www.openstreetmap.org/relation/2954632 For example I'd like to know how many kilometers of divided motorway, non-divided primary, etc. make up this route. Do I need to hire a programmer or is there an Overpass query that can generate this kind of data? asked 30 Mar '21, 19:50 mdchachi 26●1●1●1 accept rate: 0%

 1 Some of this information is available with no programming from the Relation Analyzer tool: http://ra.osmsurround.org/analyzeRelation?relationId=2954632&_noCache=on By downloading the Way Distribution you can see that this example is almost entirely highway=trunk. Note that the main highway tag in OSM does not necessarily map directly to concepts such as "divided highway", this tends to be quite country-specific. answered 30 Mar '21, 21:10 alan_gr 2.6k●1●22●45 accept rate: 15%
 1 I would like to suggest https://overpass-turbo.eu/s/15BQ: ``````[out:csv(length,highway,oneway)]; relation(2954632)->.parent; way(r.parent)[oneway=yes]; for (t["highway"]) { make stat highway=_.val,oneway=set(t["oneway"]),length=sum(length())/2; out; } way(r.parent)[oneway!=yes]; for (t["highway"]) { make stat highway=_.val,oneway=set(t["oneway"]),length=sum(length()); out; } `````` Lines 4 and 10 express that you want to sum by the value of the highway tag and could be replaced by another expression. Lines 3 and 10 ensure that oneways and none-oneways are processes separately. Line 6 has a division by 2 to count oneways only with half of their length. answered 30 Mar '21, 21:27 Roland Olbricht 6.7k●3●64●89 accept rate: 36%
