This study focuses on the assessment of the congestion impacts of fatal accidents. The paper addresses the current paucity of research into accident induced congestion levels outside of Motorway/Freeway environments, and using the SCOOT traffic control system, provides an assessment of these impacts in more heterogeneous urban environments. Levels of induced congestion are found to vary significantly according to the temporal and spatial settings in which they occur, with only accidents that occur in either peak periods or constricted network layouts producing significant induced congestion externalities in monetary terms. The detailed spatial and temporal resolutions required for such forecasts are subsequently discussed, as these raise a number of issues for SCOOT and ITS data more generally, if such analyses are to become more detailed, sophisticated, and ultimately automated, across a range of complex temporal and spatial settings.
