This function simplifies a Konigsbergr graph by reducing the graph to a simpler representation where intersections are directly connected by straight edges.

simplify_konigsbergr(graph, preserve_bridges = TRUE)

graph | A Konigsbergr graph created from |
---|---|

preserve_bridges | Boolean. Preserve full bridge geometry? |

A simple, undirected `igraph`

object.

This reduces to a simple, undirected graph, so note that the distinction
between two-way and one-way roads will be discarded. The sum of the total
distances of the removed edges are maintained, however. The real-world road
distance in meters along an edge will be saved in the `distance`

edge
attribute of the new graph.

This function relies on the simplify_topology() function from the pathfinder package.
