Cambustion fast response (high frequency) gas analysers are available in versions which support measurement of HC, NOx and CO&CO2 on board a vehicle.
Coupled with GPS and video recording, this allows the tailpipe emissions from an ICE vehicle in normal operation to be monitored, and mapped spatially.
This can be used to understand both the performance of the vehicle and specific areas for improvement, and the opportunities to reduce both emissions and human exposure through intelligent road design.
