The impact of guide sign informational density on driver cognitive load: An integrated simulator and real-world driving study.

Key Points

• The research examines how the density of information on guide signs affects the cognitive load experienced by drivers.
• Utilized both simulator and real-world driving environments to assess cognitive load
• Analyzed the effects of varying information densities on drivers
• Considered factors influencing cognitive processing in urban settings
• Increased information density on guide signs led to higher cognitive load in drivers
• Optimizing sign information can improve traffic safety
• Findings support the need for better design of urban guide signs
