“…The reactive approach employed in this context exhibits different deficiencies, namely, the constrained accessibility and substandard nature of collision data and the challenge of discerning factors. This contributes to the occurrence of collisions, which is an ethical quandary arising from the necessity of observing a sufficient number of collisions over an extended duration to conduct a statistically reliable safety analysis [ [82] , [83] , [84] ]. Hence, the employment of surrogate measures, such as the surrogate safety assessment method (SSAM) in conjunction with resources of The Swedish Traffic Conflict Technique, as a proactive and supplementary strategy for examining road safety from a more comprehensive standpoint rather than solely relying on collision-based analysis [ [85] , [86] , [87] ] has been recommended.…”

“…Based on the nonlinear traffic flow model, Du et al [25] improved the control strategy of the expressway maintenance work zones. Ge and Wu proposed a method to determine the length of the road maintenance operation area [26,27]. Peng et al [28] established the VISSIM simulation model of an expressway maintenance operation area, and proposed a method to determine the length of four-lane expressway maintenance work areas.…”

There is a body of literature on the influence range and traffic risk of fixed work zones. However, relatively few studies have examined the effect of ubiquitous moving operating vehicles, such as road cleaners, on urban roads. The influence of low speed moving work zones on road traffic flow and traffic risk is still unclear. In this work, we used simulations to establish an urban expressway three lanes VISSIM model, and selected the road traffic volume and speed of the moving work zone as the independent variables. We analyzed the range of influence of the moving work zone on the rear vehicles in the left, middle and right lanes of the urban expressway and the traffic risk variation law caused by the moving work zone. The results show that the left lane was indirectly affected by the moving work zone when the traffic volume reached 2000 pcu/h. The influence of the moving work zone on the middle lane was controlled by the traffic volume and the speed of the moving work zone. Both the left and middle lanes were mainly impacted by vehicles changing lane from the right lane. Regardless of the traffic volume and the speed of the moving work zone change, the vehicles 200 m behind a moving work zone will be directly affected in the right lane. Furthermore, the average traffic risk is the highest within 50 m of the moving work zone in the right lane. When the traffic volume decreases and the speed of the moving work zone increases, the average traffic risk decreases gradually. These results provide a scientific basis for the operation and management of moving working vehicles on urban roads.

“…Morgan et al studied the relationship between the length of the transition section in the work zone and the driving risk, of which the results showed that the reduction of the transition section length will increase the driving risk to a certain extent [25]. Ge et al used the VISSIM simulation model and the surrogate safety assessment model (SSAM) to analyze the relationship between the length of the warning zone and traffic conflicts, which showed that the traffic conflicts decreased as the length of the warning zone increased [26]. Ge et al analyzed the impact of speed dispersion on traffic risk based on the improved time to collision (TTC) model, and the results showed that reducing speed dispersion can effectively reduce driving risk in work zone [27].…”

In the expressway reconstruction and expansion engineering, the form of rightward zone is increasingly adopted, and its complicated traffic conditions can easily cause traffic accidents. In order to quickly and effectively grasp the traffic risk of the right diversion section, this study employs average speed, the coefficient of variation, the equivalent minimum safety distance, and the deceleration as evaluation indexes of driving risk, and then analyses the influence rules of traffic volume, the proportion of large vehicles, and the length of the transition section on each evaluation index by using Vissim simulation software. On the basis of this, we determine the weight of each evaluation index by the entropy method and establish the driving risk index evaluation model of the work zone with multiple linear regression. The results show that the partial regression coefficients of traffic volume, the proportion of large vehicles, and the length of the transition section to the driving risk index are 0.059, 0.317, and 0.15, respectively. Finally, in this paper, we analyze the traffic risk of example section based on the driving risk evaluation model. The results of evaluation are consistent with the number of measured conflicts. This study proposes a new method for predicting the traffic risk of the expressway reconstruction and extension engineering, which can provide a reference for the development of safety management measures in the rightward zone.
