Abstract

Violation behavior of e-bikes at the signal intersection is usually induced by the ‘herd effect’, which may easily lead to dangerous accidents. In order to study the propagation mechanism of e-bikes’ illegal crossing, taking the high mobility and flexibility of e-bikes into account, this paper proposes an illegal time-delay model based on the theory of regular Lattice. A typical signal intersection of Guilin was selected as the study subject. Its topological features are analyzed through field survey and video shooting. Further, how the violation behavior of e-bikes with different structural features evolves was investigated. Results show that the herd illegal behavior of e-bikes is sensitively affected by the degree, transmission rate, arrival rate and crossing time. Specifically, a slight increase of any of the above factors will dramatically boost the violation behavior across the whole intersection. This study may give insight into why the illegal crossing of e-bikes prevails, and help to facilitate intersection design and signal control in the future.
