The purpose of this paper is to review cost-effective methods for measuring driver behaviours (specifically driver compliance) at a signalised intersection. Driver compliance is defined as the degree to which motorists travelling through an intersection are obeying traffic control devices (i.e. traffic signals, signs etc.). More broadly speaking, evidence of a particular driving mindset may be exhibited when a driver is travelling within the posted speed on the approach to a traffic signal, suggesting the driver's willingness to stop if the light changes to amber. Measuring driver compliance can be done effectively within a short time frame. Examples of driver non-compliance may suggest problems with signal timing or signal coordination within a network, an inappropriate posted speed limit or signal heads that are incorrectly placed or are not visually prominent. Driver non-compliance, particularly red light running, may suggest a safety concern. This paper will review different possible methods of observing and measuring driver compliance, provide two specific observation methods used by the authors, suggest future avenues of research and propose present-day potential uses.
