METHODS FOR FIELD EVALUATION OF ROADWAY-DELINEATION TREATMENTS

The objective of this study was to establish the relationships between various traffic-performance measures and accident probability on two-lane rural roads. This information would enable researchers to evaluate new roadway-delineation treatments without having to collect before-and-after accident data over a period of many years. Accident data and speed and lateral-placement measures were collected for typical roadway sections of both tangent and curvilinear alignment. Multiple linear regression analysis was then used to develop an accident-probability model. Important influencing variables were centrality of vehicle placement within the traveled lane, difference in lateral placement along the roadway section, skewness of the speed distribution, pavement width, and shoulder width. Procedures for the field evaluation of delineation-treatment effectiveness were then specified. /Author/
