A comprehensive and accurate evaluation of takeover risk is the key to improve the safety of automated vehicles takeover. The researches on takeover mainly focus on the factors affecting the takeover performance, and rarely involve the quantification of the risk of automated vehicles takeover. This study considering the influence of traffic physical object shape on the field distribution, the existing Driving Safety Field was improved. On this basis, the safety index of takeover was established, and a risk evaluation method of takeover considering multiple risk sources was proposed. The experimental results show that the improved field strength distribution is more consistent with the actual situation, and it solves the problem of overestimating and underestimating risk. The proposed takeover risk evaluation method considering multiple risk sources has good rationality and advanced nature.
