DURING 1956, THE LOUISIANA DEPARTMENT OF HIGHWAYS, IN CONJUNCTION WITH THE BUREAU OF PUBLIC ROADS CONDUCTED A NUMBER OF RESEARCH STUDIES ON US 71 NEAR LEBEAU TO DETERMINE THE EFFECT OF PAVEMENT EDGE STRIPING ON THE LATERAL PLACEMENT OF VEHICLES ON 24-FT TANGENT HIGHWAYS. RESULTS OF THE STUDY INDICATED THAT A CONTINUOUS EDGE STRIPE OR LINE HAD NO EFFECT ON VEHICLE PLACEMENT DURING THE DAY, BUT AT NIGHT THE CONTINUOUS LINE TENDED TO MOVE VEHICLES SLIGHTLY TOWARD THE CENTERLINE. DURING THE SUMMER OF 1957, THE DEPARTMENT, AGAIN IN COOPERATION WITH THE BUREAU OF PUBLIC ROADS, REPEATED THE PLACEMENT STUDY ON 24-FT TANGENT HIGHWAYS IN A DIFFERENT PART OF THE STATE IN AN EFFORT TO VERIFY FINDINGS OF THE INITIAL STUDY. IN ADDITION, THE SCOPE OF THE STUDY WAS BROADENED TO INCLUDE A STUDY OF A SECTION OF TANGENT 20-FT ROADWAYS, A SECTION OF 20-FT ROADWAYS ON A 4-DEG CURVE, AND A SECTION OF 4-LANE DIVIDED HIGHWAY WITH 12-FT LANES IN ONE DIRECTION AND 10-FT LANES IN THE OTHER. IN ALL CASES, SHOULDERS WERE IN COLOR CONTRAST TO THE THROUGH ROADWAYS. /AUTHOR/
