Hold the Red evaluation

CARRS-Q developed a methodology to undertake an evaluation of a trial of a new intelligent collision prevention system, known as Hold the Red (HTR), at four Combined Red Light Speed Camera (CRLS) sites.

The evaluation considered the technical performance of the system, as well as road safety implications of the system.

The objectives were as follows:

● Determine if the HTR is performing as intended; and
● Determine what impact HTR has on safety and traffic flow at the trial intersections.
