摘      要：Purpose–This study aims to investigate the safety effects of work zone advisory *** traditional system includes a dynamic message sign(DMS),whereas the advanced system includes an in-vehicle work zone warning application under the connected vehicle(CV)***/methodology/approach–A comparative analysis was conducted based on the microsimulation ***–The results indicate that the CV-based warning system outperforms the *** this study,the optimal distances of placing a DMS varies according to different traffic ***,negative influence of excessive distance DMS placed from the work zone would be more obvious when there is heavier traffic ***,it is recommended that the optimal distance DMS placed from the work zone should be shortened if there is a traffic *** was also revealed that higher market penetration rate of CVs will lead to safer network under good traffic *** limitations/implications–Because this study used only microsimulation,the results do not reflect the real-world drivers’reactions to DMS and CV warning messages.A series of driving simulator experiments need to be conducted to capture the real driving behaviors so as to investigate the unresolved-related *** machine interface needs be used to simulate the process of in-vehicle warning information *** validation of the simulation model was not conducted because of the data *** implications–It suggests for the optimal DMS placement for improving the overall efficiency and safety under the CV ***/value–A traffic network evaluation method considering both efficiency and safety is proposed by applying traffic simulation.
