I'm using ArcGIS 10 Network Analyst Extension to try and incorporate their driving directions functionality into a walking network. I am wondering if there is any way to alter the RoadClass Values to be more suitable for a Walking Network. For example:
RoadClass Value: 3
Type of Road Class: Ramps
Example: Take ramp and go on US-59 N
Is there any way that I can modify or add a RoadClass value to be "Stairs" and instead of saying "Take ramp..." it says "Traverse stairs..." or "Elevators" saying "Use elevator"?
