The environmental performance of road vehicles deteriorates after they have been in operation for a while, without many drivers becoming aware of this. Regular inspection may be take place only years later, and it only measures exhaust emissions at idle-running of the engine.
With a view to reduce pollution, the REVEAL project will therefore develop, install and validate a fully engineered prototype of a low cost instrument to measure, at the roadside, gaseous and/particulate emissions from individual vehicles in motion under normal driving conditions.
The instrument will be coupled to existing automatic number plate readers to allow information on vehicle type, age, and engine size and type to be correlated with the emission measurements. The low cost of the system combined with its flexibility in terms which pollutants it can measure will enable its use in long-term installations and multiple locations to provide continuously updated data on real-world emissions. This data is also needed to model the impact of policy or legislation changes more precisely then presently possible.
The system will be installed initially in three European cities to compare the effects of climate, street geometry, driver behaviour and fleet differences on emissions inventories.
