The study objectives are to establish whether mass produced, accurate traffic counts from very high-resolution earth observation satellites, combined with traffic emissions and air quality models, can be used to provide data to fulfil our customer’s needs in a cost effective and timely way.
Traffic has an important impact on air pollution and health, but datasets of this kind are at best only available in advanced western cities, rarely at country scale and too often unavailable in low and middle income countries.
The proposed system is summarised as follows:
1. To count vehicles using very high-resolution satellite imagery;
2. To create vehicle emissions road-by-road and combining these with other emissions, to predict high resolution air quality concentrations in any city;
3. To develop an air quality service that allows users to access traffic counts, traffic emissions and air pollution predictions, through a web portal and mobile applications, with both one-off purchasing, and subscription payment models available.
The Feasibility Study includes the development of a proof of concept, aimed at obtaining further customer buy-in and to develop user needs.
The Users and Customers involved in the Feasibility Study fall within the sectors identified below.

The air quality service allows users to access traffic counts, traffic emissions and air pollution predictions for their city, through a web portal and mobile applications, with both one-off purchasing, and subscription payment models available.
Our service offers on-demand world-wide air quality modelling information at a very high level of detail (20 metre resolution). Spatial modelling of this kind are only possible through detailed knowledge of emissions sources, with vehicles being one of the most important. The road emissions will be added to all other emissions sources both anthropogenic (industry, power generation, commercial and domestic fuel combustion, other mobile machinery etc) and biogenic to create the final air pollution maps.
Vehicle locations and speeds are extracted through interrogation of Very High Resolution (VHR) satellite imagery (0.5m resolution) providing the following advantages to air quality modelling:
The Feasibility Study is complete with users and customers successfully consulted to test the Proof of Concept dataset. System and service architecture has been tested which has produced feedback and recommendations which will be built into an upcoming Demonstration Project and furthermore into deployment of a sustainable operational service through a new Joint Venture company formed between the parties.
