In order to provide the CELLO (CEntraL LOndon) Board (composed of senior TfL management and Borough representatives) with an impact assessment of planned schemes on the road network in central London over the next five years, Colin Buchanan developed a series of future year SATURN models from the CRISTAL-H refresh model.

Colin Buchanan produced an extensive set of SATURN results and a comprehensive analysis of each scenario to inform the CELLO board about how the planed network developments will affect central London at Borough and sector level.  This included converting SATURN results into a GIS database for detailed graphical analysis.

A set of performance indicators for the network were also produced and presented to the CELLO Board.  The performance indicators included an estimate of the capacity of the individual sectors within the study area and average speeds at sector and borough levels.  A set of heat diagrams, which are more easily understood by non-technical audiences, were then produced to show the performance of the network for the base and future scenarios. Recent tests have included the impact on emissions of increased usage of electric vehicles in London.
