Driving safety has been a key problem to the health and sustainable development of the transportation system. This paper focuses on the identification of behavioral risks under natural driving conditions based on GPS data, and examines the risk assessment and expression of behavioral characteristics of driving behaviors under natural driving conditions. The natural driving behavior database based on GPS data was established,and the behavior risk assessment method based on the information entropy under the condition of natural driving was put forward. The in-depth exploration of risk characteristics of individual drivers’ driving behaviors and the construction of driving behavior map provide practical solutions for the prediction and early warning of behavioral risks of ordinary drivers under daily and natural driving conditions. This study provides a theoretical reference and technical support for promoting the improvement of road traffic safety.
