Short summary

Ultra-fast response engine exhaust emissions analyzers have been adapted for on-board vehicle use combined with GPS data. We present, for the first time, how high spatio-temporal resolution data products allow transient features associated with internal combustion engines to be examined in detail during on-road driving, revealing the detailed causes behind emissions hot spots. In particular, NOx pollution was assessed in detail for a number of road network features (e.g. speed bumps).
