A corridor analysis approach to selecting combined red-light speed camera sites in Queensland
Submission Date: 2019
During 2018, an enhanced methodology was developed for selecting suitable sites for the placement of combined red-light speed cameras within Queensland. Preliminary evaluations of recent installations suggest that the combined red-light speed cameras can influence crashes at the immediate site and at other signalised intersections along the adjoining road corridor, providing support for previously reported “halo effects”. Using this reasoning, the Department of Transport and Main Roads (TMR) revised its site selection methodology to prioritise placement by ranking road corridors in one-kilometre segments on the prevalence of red-light violation type crashes and speed related crashes.
