Transfund New Zealand funded the development of a signal audit methodology in order to examine the safety and efficiency of traffic signals. A representative number of signal installations across nine territorial local authorities (TLAs) were audited. Stops & Goes of Traffic Signals presents findings of this study. Targeted at engineers who design, construct, install, manage and maintain traffic signals, the booklet examines the key factors required for safe and efficient operation of signalised intersections. These include technical requirements of the signals such as phasing and operational issues, intersection and lane layout, placement of signal posts, road marking, conspicuity of signals and other factors influencing the environment at intersections.
