Three such alignments, with simple and complex curves were designed to generate desired traffic volumes for different levels of service. The driving simulator at Ryerson University was used to simulate the roadway alignments. Data was collected from twenty drivers that participated in experiments using the driving simulator. Statistical Analysis Software (SAS) Enterprise Guide was used to analyze and process output data. Models were developed for visual demand and volume/capacity ratios, and geometric characteristics of the road, where visual demand was the dependent variable,and other variables were the independent variables. The research proved that there exists a relationship between visual demand and different traffic volumes along with geometric characteristics of the road.
