Example of Context-Specific Route Directions

Here is a small example of a context-specific route direction for a given route.

The figure displays a sketch map of the example route (the bold, red line), showing street names and landmarks encountered along the route. Its main characteristics is that a wayfinder has to follow a river for a considerable part of the route. This is reflected in the context-specific route directions in that decision points 3 to 8 are combined in one chunk.

The following XML-code lists the abstract, relational specification of the context-specific route direction as produced by GUARD. Each Direction-tag contains one chunk, i.e. one instruction of the context-specific route directions (which possibly covers several consecutive decision points). For further details please refer to our publications.
