Abstract:The objective of this project was to develop Super 2 design criteria in a format suitable for inclusion in the TxDOT Roadway Design Manual. Site evaluations were conducted in Texas, Kansas, and Minnesota, including before-and-after studies of driver behavior for variations in pavement markings. A hypothetical two-lane, two-way rural highway with varying length and spacing of passing lanes was simulated under a variety of traffic mixes and two-way traffic volumes. Additionally, laptop-based surveys were conducted to determine driver reaction to various passing lane spacings, wording on related signs, shoulder widths, and pavement markings entering a passing lane section. Recommendations for the TxDOT Roadway Design Manual were developed based upon these activities.
