CORRELATION OF ROAD AESTHETICS AND VISUAL PARAMETERS FOR TRAFFIC SAFETY IMPROVEMENTS

Lidia Żakowska

Abstract

The proposed paper concerns an experimental study in the area of geometric road design related to road aesthetics and safety. The research objective was to develop a method for road safety evaluation based on complex information from road environment. Based on subjective assessment of moving road view, the relationships between road design and environmental parameters and characteristics that enhance safety are investigated. The laboratory experiment presented in the paper is based on the three-dimensional visualization of alternative road designs. Multi-parametrical studies of road view perception were provided in two ways, namely: (1) driver’s subjective assessment of road characteristics and road safety, (2) multi-variance analysis of objective road parameters and subjective road characteristics and safety. The results show the effect of geometric road parameters on subjective assessment of road aesthetics, driver’s speed choice and road safety perception. The applied method is being tested for practical use in three-dimensional computer aided road design evaluation. 1.
