I have the following data; a road network for a city, a number for routes through the city and a point file for each junction where a manoeuvre is required.
What I want to identify are the start and end road segments for each manoeuvre along the routes and in the direction the route is.
For example, if the route makes a "right turn" I want to identify the road element before the turn and the road element after the turn is made. This order should be in the digitisation direction of the route. I then want to use the information to tag the road elements as "from" and "to" and grouped by the junction ID.
At the moment I have been able to select the road elements that make up the manoeuvre but I am struggling to sort them into the correct order of sequence (i.e. in the direction of the route). Any ideas on how I can achieve my desired results?
