Abstract:
A method of computing sign text for branches from a carriageway of a processor readable representation of a network, the method comprising the steps of:accessing the processor readable representation of a network; selecting a branch of the processor readable representation of a network for which sign text is to be computed; initializing a sign text variable; constructing a first name list for a first road element that crosses the carriageway at a first junction; constructing a second name list for a second road element that crosses the carriageway at a second junction; computing sign text for selected branches of the processor readable representation of a network; wherein the computing step further comprises the steps of: computing sign text for a simple branch of the processor readable representation of a network using a first process; and computing sign text for a compound branch of the processor readable representation of a network using a second process; placing computed sign text into the sign text variable; and outputting sign text computed for selected branches of the processor readable representation of a network.
