Reporting empirical marginal costs in SCATS

In economics, the marginal cost is the change in total cost of service (or production) for an increment of that service (or production). Analysis of marginal costs allows judgements to be made regarding profitability, or value generation generally. In 2015 in New South Wales (NSW) a new facility termed the Strategic Performance (SP) framework has been introduced in SCATS that reports the physical and economic performance of SCATS operation at each instrumented detector, at each traffic signal service. Included in the SP is the reporting of marginal costs. Performance from customer and service perspectives are reported and provision is made to differentiate customer types, e.g. general vehicles, tracked prioritised vehicles and pedestrians, given available SCATS measurement. SP marginal costs indicate the marginal change in total customers travel time cost for marginal changes to the traffic signal scheduling. An example is the marginal time cost for an increase in the terminated duration of the traffic signal service, e.g. red signal for vehicles, ‘don’t walk’ signal for pedestrians. We demonstrate how the SP marginal costs inform on the performance of the traffic signal operations. We provide insight why SP marginal costs and the SP framework generally readies SCATS for the challenges of C-ITS and autonomous vehicles.
