Investigations of impacts of junction design on emissions: are our junctions sustainable?

  Purpose - An investigation of the driving behaviour and impacts on emission at two traffic junctions

Design/methodology/approach - A signalised junction and a roundabout in Edinburgh have been selected. An instrumented car has been used and a GPS to monitor driving activities as well as a gas analyser to monitor the vehicle’s emissions during the evening peak hour

Findings - Vehicles’ emissions are affected by a large number of factors including characteristics of the engine and the vehicle, characteristics of the road, the fuel used as well as driving behaviour

Originality/value - Different methods and approaches have been used to investigate behaviour of vehicles at various traffic junctions. The main aim however, has mostly been to reduce travel times as well as traffic delays and queues at the junction. Consideration of environmental impacts have been also considered but often as a by product of congestion reduction and not as a main aim
