Field interviews were conducted with drivers experiencing route choice difficulties at nine study sites in Pennsylvania and Maryland at which detailed observations established the causes and characteristics of erratic maneuvers. Subsequently, signing and marking improvements were made at several sites and their effectiveness was measured by further observations. Over-all, a one-third reduction in erratic movements was recorded in the 'after' studies. Further analysis of the effectiveness of different delineation treatments and of the time characteristic patterns of erratic maneuver by day of week and time of day are reported extensively in appendices.
