The Behavior Analysis of Pedestrian-cyclist Interaction at Non-signalized Intersection on Campus: Conflict and Interference

AbstractPedestrian-cyclist interaction is closely relative with traffic safety on campus intersection. The relationships of flow, speed, Level of Service (LOS) with pedestrian-cyclist conflict and interference were studied. Studying pedestrian-cyclist interaction was using collected video data which recorded the behaviours of pedestrians and cyclists at a non-signalized intersection on campus. The pedestrians and cyclists’ flows were recorded by video statistic software, the collected videos were decoded into image frames, their trajectory and distance data were acquired by image processing software, the data was converted into numbers as a VCNXY(Video number, Current frame no, Pedno, Pedx, Pedy) database, then their speeds were computed by Euler's formula. The LOS is classified with three levels under different traffic density and road traffic capacity. Through the analysing of pedestrians and cyclists’ flows and their average speeds at different time, and analysing the relationships with pedestrian-cyclist interaction and their flow, speed, LOS. Results showed that campus’ transportation is much different from city transportation, the proportion of pedestrians and cyclists are much higher, the average speeds of pedestrians and cyclists are lower. Experimental results show that flow, speed and LOS are very strongly related to pedestrian-cyclist interaction
