Abstract EN
Overtaking experiments on four two-lane highways were conducted.
The data of overtaking conflict time (the time difference between the time of driving back to the original lane and the time of meeting with the first opposing vehicle) and experimental drivers’ risk feeling were observed.
Membership was adopted to denote the experimental drivers’ risk feelings which also denote the severity of traffic conflict.
Membership ranges from 0 to 1 and corresponding risk becomes higher; that is, traffic conflict becomes more serious.
According to the observed relationship between overtaking conflict time, and drivers’ risk feeling membership, Cauchy distribution function was adopted as membership function.
The thresholds of the severity of traffic conflict were determined through Delphi method.
The relationship model among traffic volume, overtaking conflict time and design speed was established according to experimental data.
Then the idea of setting auxiliary lane on two-lane highway in China was presented.
And the traffic volume values that need setting auxiliary lane corresponding to different design speed and traffic conflict degree were given according to the established model.
It is expected to improve the traffic safety level of two-lane highway in China through setting auxiliary lane.
