Validation and applicability of floating car speed data for road safety

Popis výsledku v původním jazyce

(presented at 2017 Australasian Road Safety Conference, Perth, 10. – 12. 10. 2017) Traffic speeds are one of the most important factors influencing road safety outcomes. Arrival of ‘big data’ and powerful analytical methods opened a new avenue for obtaining and applying traffic speed data for road safety purposes. This paper briefly explores conventional speed data sources and the comparatively new floating car data (FCD) as a source of speeds. It then compares the conventional spot-speeds with FCD speeds for selected parts of the road network in Victoria. Presented analyses shows a systematic relationship between the two data types, with FCD speeds being lower than spot-speeds. Availability of FCD speeds was much greater than spot-speeds, covering most of the public road network. With appropriate understanding, FCD speeds could be used for many road safety purposes: network-wide speed monitoring, and for informing and evaluating speed management. Further exploration of specific use-case feasibility, precision and data calibrations are planned. The paper points to new opportunities for safety monitoring and evaluation, and for development of more sophisticated speed-safety models than those currently available.
