I am using ArcMap.
I have polylines of 80+ bus routes operating in a city. The polylines have attribute values for the number of passengers, number of trips, etc. Many of the polylines overlap at certain areas of the road network. What I want to do is to save the overlapping portions into separate individual shapefiles, that have attribute values that correspond to the sums of those original values.
I know how to do this the long way (find the overlaps, cut them and save the separate shapes, manually calculate the attribute values, enter and save the data) but is there a way to do it easier/faster without using scripts?
For example in the image above, the Green Route has 1,000 passengers and travels 20 trips a day while the Orange Route has 500 passengers and 10 trips a day. I'd like to cut out the overlapping area and save it as a separate shapefile with data on 1,500 passengers and 30 trips. This is just a simple example with two routes but I have 80+ in all that overlap in many locations with each other.
