Validation and Applicability of Floating Car Speed Data for Road Safety
Keywords: Speed Limits 1
Traffic speeds are one of the most important factors influencing road safety outcomes. The project compares floating car data (FCD) speeds with conventionally collected point-speed data for different parts of the road network in Victoria. Analysis showed a clear relationship between the two data types. Simple calibration models were developed to interpret FCD speeds in the context of conventionally measured free-flow speeds. Availability of FCD speed data was much greater than for point-speed data, covering most of the public road network. The project also noted some limitations, but pointed to opportunities for more sophisticated speed-safety models than currently available.
