Multimodal Safety Analysis of the implementation ofrectangular rapid flashing beacons (RRFBs)

With the increased number of non-motorist related crashes, there is a growing need for accommodating the safety of active modes in urban areas. The City of Calgary has recently installed rectangular rapid-flashing beacon (RRFB) at several locations in the City in an attempt to improve cyclists and pedestrians’ safety. RRFB use dual rectangular LED lights to display intermittent rapid flashes similar in operation to emergency flashers on police vehicles. These devices were shown to assist motorist yielding behaviour at some particular locations. However, more analysis is needed to further evaluate the effectiveness of these new systems as more experimental data is needed. The purpose of this study is to evaluate the effectiveness of the RRFB system at several locations in the City to determine the effect of this new operation on pedestrian and cyclists safety. The specific objectives of this study are : 1) determine the long-term effectiveness of RRFB, 2) identify variables related to the efficacy of RRFB's, and 3) identify and recommend how FFRB's effectiveness can be improved.
