Abstract:This study was conducted to determine the effects of short-term pavement markings on driver performance. Three different marking patterns were tested within the scope of this study: 2-ft stripes with 38-ft gaps (0.61-m stripes with 11.58-m gaps); 4-ft stripes with 36-ft gaps (1.22-m stripes with 10.97-m gaps); and 10-ft stripes with 30-ft gaps (3.05-m stripes with 9.14 gaps) and edgelines. The first two patterns are the temporary markings examined without edgelines while the third scenario is the full complement of markings, including edgelines, recommended in the MUTCD. Data were collected for all three marking patterns during day and night and under dry and wet weather conditions. The data analysis consisted of comparing a number of operational measures collected for the three marking patterns including: 1) lateral placement of the vehicle on the roadway; 2) vehicle speed within the test segment; 3) number of edgeline and lane line encroachments; and 4) number of erratic maneuvers, e.g., sudden directional changes. This final report summarizes the effects on driver performance associated with the different marking patterns tested. The results of this study are presented to help organizations develop guidelines for short-term pavement marking policy.
