The Evolution of the SCATS and the Environment Study

By Christian Chong-white, Gareth Millar, Fraser Johnson and Steven Shaw

Abstract

This paper explains the evolution of a running study titled ‘SCATS and the Environment’ (SatE) by the Roads and Traffic Authority of New South Wales (RTA) (NSW). SCATS is a comprehensive traffic management system that provides adaptive traffic control, amongst other functionality. The SatE study is tasked to rigorously demonstrate the transport, environmental and economic value that the SCATS installation provides to the people of NSW. We consider the evolution of the SatE study to have two forms: (1) methodological and (2) experimental. We use these forms to describe an ordered schedule of salient decision points that records the progress of the study. We explain the incrementally developed and refined experimental design that is specifically targeted to defensibly assess SCATS performance outcomes. This paper provides some insight for modelling practitioners on the appropriate experimental design of studies that investigate automated traffic control. The presentation puts on public record the details of the study process to support the publishing of the SatE traffic performance results in another paper. 1
