May 7, 2019 at 21:15 | comment | added | sailestim | @user3386170 yes, I've done that and have also checked coordinates to be sure that they use the same ones | |
May 7, 2019 at 20:48 | comment | added | kl-higgins | Have you tried zooming in really closely to make sure the segments really connect? Or using snap to replace the ends of the segments to the vertices? Sometimes, it looks like one line but there are tiny gaps that interfere. | |

May 7, 2019 at 17:53 | comment | added | sailestim | Since I have 100k features in my road network shapefile, the merge function instead of dissolve is ineffective by time. 20% of the progress took over 8 hours to compile, so I want to find out another solution | |
May 7, 2019 at 17:23 | comment | added | sailestim | @user3386170 thanks for your answer. Yes, I've tried dissolve function and also mentioned this in the text of my question. I did it with Vector -> Geoprocessing Tools -> Dissolve without any attribution. Then I tried Vector -> Geometry -> Multiparts to Singleparts and finally Vector -> Analysis Tools -> Line Intersection. | |

Did you try this as suggested in comments of that post: "It look like your lines are splitted into smaller parts that's why your output return so many points. Try to first dissolve your shapefile without any attribution and after run line intersection again"? Please clarify how to you dissolve, multipart-to-singlepart , etc.
