Abstract:

This study investigated the effects of different spatial locations of road guides, road types, intersection turns, traffic flow, and time periods on the driving stability and mental load of novice drivers in steering scenarios. Using a virtual driving simulation platform, mixed orthogonal tests were conducted with factors including road guide spatial locations, road types, intersection turns, traffic flow, and time periods. The test indexes included the standard deviation of the steering wheel turning angle and the pupil coefficient of variation. Using range analysis and interaction comparison of the test results, the optimal factor level combination was determined and analyzed. The results showed that the primary factors affecting driving stability were, in order of importance: intersection types, time periods, road guide spatial locations, and traffic flow. For mental load, the factors ranked as: road guide spatial locations, time periods, intersection types, and traffic flow. The spatial locations of road guidance, as a design element of head-up display (HUD) road guidance, either promoted or interfered with driver stability while consistently reducing mental load. These findings provided a reference for the design of information related to HUD road guidance, significantly contributing to HUD information design research and urban road driving research.
