Abstract EN
In this paper, the decision-making model of discretionary lane-changing is established using cumulative prospect theory (CPT).
Through analyzing the vehicles’ dynamic running states, safety spacing calculating approaches for discretionary lane-changing and lane-keeping have been put forward firstly.
Then, based on CPT, a lane-changing decision model with accelerating space as its utility is proposed by estimating the difference between actual spacings and the safety spacings for discretionary lane-changing as well as lane-keeping.
In order to calculate the utility of discretionary lane-changing, dynamic reference points and a parameter representing driver’s risk preference are introduced into the model.
With the real data collected from an urban expressway, the distribution of discretionary lane-changing duration is analyzed, and the model parameters are also calibrated.
Furthermore, the applicability of the model is evaluated by comparing with the actual observation and random unity model.
Finally, the sensitivity analysis of the model is carried out, that is, assessing the influence degree of each variable on the decision result.
The study reveals that the CPT-based model can describe discretionary lane-changing behavior more accurately, which consider drivers’ risk-aversion during decision-making.
