The simplyfAI project: Using AI planning in urban traffic management or if at first the representation does not work, try, try and try and again

This paper is an experience report on the results of a collaborative one year feasibility study called "SimplyfAI" funded by Innovate UK. This concerned sourcing and enriching urban traffic data, and using this data as inputs to a system to generate urban traffic strategies in order (primarily) to improve air quality. This paper reports on the development surrounding the AI planning component of that work: the engineering and configuration issues that were found in this application. It discusses a range of issues and lessons we learned through the experience of collaborating with end users and technology developers.
