In order to study the relationship between deceleration behavior and facility setting in the construction area of expressway reconstruction and expansion, the variation of average deceleration in the construction area of reconstruction and expansion was studied by taking the type of speed limit sign in the warning area and the distance between construction areas as independent variables. The driving simulation scene in the construction area of highway reconstruction and expansion was established, and 30 drivers with different driving experience were recruited to carry out driving simulation test, driver behavior data and information were also collected. The multi-factor analysis of variance (anova) was used to compare the difference of drivers’ average deceleration under different facilities, and relevant models were established. The results showed that under a single speed limit sign, the spacing between the average deceleration of 5 000 m construction areas was larger than the average deceleration of 2 000 m construction areas. The average reduction speed of the step by step speed limit sign is smaller than that of the single speed limit sign. Experienced drivers decelerate more smoothly. The number of traffic signs had the greatest effect on the average deceleration.
