Road Node

A point spatial object that is used to break up the Road Network for connectivity. The Road Network splits for the following circumstances:

• The location where an attribute recorded on the Road Link changes (for example, its name or form)

• The intersection or crossing of roads (including bridges, flyovers, and tunnels where there is no connectivity)

• The start / end of a Road feature

• Where a one-way routing feature starts or ends

• Where a tunnel starts or ends

• Change of local highway authority

• Where there is a connection to the Path Network
