Additional information:
This paper deals with improving the capabilities of Large Language
Models (LLM) to provide route instructions for pedestrian wayfinders by
means of qualitative spatial relations. We use a method called Retrieval-
Augmented Generation (RAG). RAG supports the LLM with context in-
formation based on the specific query. We assess the impact the added
information has on model performance for generating pedestrian route
instructions. Our findings encourage further integration of qualitative
spatial data into LLM applications—potentially benefiting areas such as
digital navigation aids, smart city tools, and accessibility technologies.
