Investigating the Effect of Long-Term Worksites on Road Users

Abstract: A large part of German motorways is increasingly in need of modernization. In addition, the dimensioning of traffic routes has to be adapted to consistently growing traffic volumes. Worksites that have to be installed for road preservation and development are planned, following the existing technical regulations. However, the human factor is only considered poorly. Many accidents and traffic disturbances at worksites could be avoided if the driving behavior of road users would be taken into account for the particular situation "worksite". Therefore psychological aspects need to be taken into account for the design of future worksites. In the present study, funded by the Federal Ministry of Transport and Digital Infrastructure, not only driving behavior, but also heart rate and eye movement of the subjects were measured during test drives in real worksites in order to capture the behavior, workload and attitude that arise for road users when passing a worksite. In addition, longitudinal and lateral distances were detected by means of video cameras and additional measurements were performed at cross-sections. Based on these variables, local traffic parameters were determined. Based on the findings obtained in the study, recommendations for the installation and arrangement of worksites will be compiled which give consideration to the driving behavior. Overall, the aim is to reduce workload for road users in areas of worksites and thereby increase traffic safety.
