Cutin Behavior Analyses Based on Naturalistic Driving Data

Abstract:

Based on the realistic driving behavior data collected by Shanghai Naturalistic Driving Study, an automatic extraction algorithm was developed and 4 734 cutin events were identified. This study aims to make indepth analyses on the characteristics of cutin preparation, execution and its impacts on the following vehicle. The results show that cutins are mostly motivated by avoiding slow preceding vehicles in the original lane. Cutin duration and turn signal usage of the Chinese drivers are both less than those of the United States, which shows a more aggressive driving style. About 15% of the followers accelerate with a speed change rate of more than 10% in response to cutin behavior for their discourtesy or intolerance. Compared to freeways and expressways, the cutin behavior on surface roads has a greater impact on the following vehicles and it is more dangerous with higher risks.
