I have a large map of every street in the country. This is a vector layer in QGIS many streets are split by OSM , IE have a different OSM ID yet the street has the same name. Often these streets are split at intersecting points. Ideally I'd like to join them using Qgis and then export my shapefile My software previously looked at points in a route and determined if the street the user was on, or turning onto, continued or ended at the intersection: hence allowing me to determine road rules for the intersection. For example our main street is one road, but is split into about 10 sections. Is there an "easy" way to join streets or determine if the street is the entire street or just a section of the street ?
ArcGIS has a tool called Dissolve that can do this, though from what I read the QGIS equivalent only does polygons. That article mentioned you can still do it with "Vector > Geometry Tools > Singleparts to Multiparts" The (much) slower alternative would be an attribute selection for each name and then merging the geometry of those records.
