Red-light Running Behaviors of E-scooters and E-bikes at Signalized Intersections in China

摘要

A comparative analysis was conducted to compare the red-light running behaviors of the riders of e-bikes, e-scooters and bicycles as they were crossing signalized intersections. The crossing behaviors of 5,646 individuals, including the riders of 1,568 e-bikes, 2,612 e-scooters, and 1,466 bicycles were observed. The average red-light running rate for e-bikes, e-scooters and bicycles at the selected sites was found to be 24.9%, 25.0%, and 18.3%, respectively. The red-light running rates for e-bikes and e-scooters are significantly higher than those for bicycles. The difference in the red-light running rates for e-bikes and e-scooters is not statistically significant. A binary logit model was then developed to evaluate how various factors affect the red-light running rates of two-wheeled vehicles at signalized intersections. Comparing the traffic conflicts caused by various red-light running two-wheelers, it was found that bicycles were slightly more likely to be involved in traffic conflicts than e-bikes and e-scooters as they were crossing intersections during a red pedestrian phase. In addition, e-bikes are less likely to be involved in traffic conflicts in the middle stage of a red pedestrian phase than e-scooters and bicycles. Both e-scooters and e-bikes have higher crossing speeds than bicycles. Even though e-scooters have significantly higher speeds than e-bikes as they were crossing intersections during green phases, the difference in the crossing speeds between red-light running e-bikes and e-scooters is not statistically significant.
