Get ordered path to calculate kilometer

Hi there, i have got a list of incident in Italian motorway and the kilometer where they happened. I should find lat and long of the event. I extracted all nodes from the motorway using this script:

[out:json][timeout:25];
//fetch area “Italy” to search in
{{geocodeArea:Italy}}->.searchArea;
//gather results
(
// query part for: “highway=motorway and ref=A14”
node["highway"="motorway"]["ref"="A14"](area.searchArea);
way["highway"="motorway"]["ref"="A14"](area.searchArea);
relation["highway"="motorway"]["ref"="A14"](area.searchArea);
out body;
>;
out skel qt;

The problem is that while nodes are ordered (so i can calculate relative distance in km of a way), ways aren't. This means i can't create a path of way from the start of the street till the end.

Is there any way to order ways and calculate absolute distance in km?

Thanks for help
