Abstract
A survey to compare vehicle and travel characteristics under three different signal control modes (Scat dynamic, linked vehicle actuated and isolated) was conducted on a 13.5 kilometre section of Maroondah Highway during 1982. The survey was conducted in two parts- an instrumented vehicle survey to ascertain route operational comparisons and an intersection delay survey to ascertain the effects of the three signal modes on side- road traffic. This paper provides details of the design, conduct and results of the Maroondah highway survey, and of the lessons learnt regarding the design and operation of the traffic signal system.
