Abstract:

The purpose of this paper is to examine the effect of variability in pedestrian volume on cyclist- vehicle interactions after accounting for the effect of cyclist and vehicle volumes. Interactions between cyclists and motor vehicles at six signalized intersection were identified in this study using an objective conflict indicator; Post-Encroachment Time (PET). A total of 83 videos were reviewed and 465 interaction events were identified. A total of 3,688 through cyclist movements, 6,522 right-turn vehicle movements and 23,512 individual pedestrian crossings were recorded. A threshold of 3 seconds was used to identify interaction events based on measured PET. The results showed that the pedestrian volume was found to be associated with a positive (desirable) impact on cyclist safety when vehicles yielded to the cyclists while making a right turn movement across the cyclist path. This was statistically significant for PET proximity levels (0, 2] and (0, 3] seconds. However, when motorists failed to yield to cyclists, the effect was not significant. Furthermore, the variability in pedestrian volume was not associated with vehicles blocking cyclist path while making a right-turn movement. It may be argued that the increased presence of pedestrians may promote safer crossing of cyclists across right-turn vehicles when motorists yield to cyclists.
