From the perspective of drivers' psychology, the drivers' behavioral decision-making process and its influence factors were analyzed. Based on the dates surveyed, the Logistic model of drivers' behavioral decision-making at signalized intersection with countdown display unit was established, which was also compared with the model without countdown display unit. The sensitivity analysis results of these two models were given at last. The results indicated that the countdown display influenced the drivers' behavioral decision-making significantly. These fundamental works provided some knowledge to traffic management to accelerate the process in the improvement of countdown display setting and gave some advices to promote the safety of intersections. |
