rnet <- overline(routes_fast[c(2, 3, 22), ], attrib = "length")
plot(rnet)
lines(routes_fast[22, ], col = "red") # line without overlaps
islines(routes_fast[2, ], routes_fast[3, ])
islines(routes_fast[2, ], routes_fast[22, ])
# sf implementation
islines(routes_fast_sf[2, ], routes_fast_sf[3, ])
islines(routes_fast_sf[2, ], routes_fast_sf[22, ])
# }
