Analyzing traffic incidents is an important part of traffic incident management (TIM). In this paper, a traffic incident analysis method based on the accumulative ratio (AR) and extended spectral envelope (ESE) methods is presented. AR is used to analyze the spatial-temporal evolution of a bottleneck caused by a traffic incident. The ESE method is used to detect key time points in the progression. An empirical study of a typical traffic incident on the 4th Ring Road East in Beijing was carried out and shows that the proposed methods can effectively trace the bottleneck and discover the key time points, which can provide a theoretical basis for traffic incident management.
