INFORMATION LEAD DISTANCE STUDIES - ELECTRONIC ROUTE GUIDANCE SYSTEMS

THIS IS A REPORT ON A SERIES OF STUDIES THAT WERE PERFORMED ON THE INFORMATION LEAD DISTANCE (ILD) REQUIRED BY DRIVERS IN ORDER TO EXECUTE SUCCESSFULLY CERTAIN HIGHWAY TURN MANEUVERS, SUCH AS LANE CHANGES AND TURNS. EXPERIMENTS WERE PERFORMED TO COLLECT EMPIRICAL DATA TO BE USED IN ILD ESTIMATING PROCEDURES. MEASURES WHICH WERE BOTH SENSITIVE AND RELIABLE INN DETERMINING ILD'S WERE IDENTIFIED AND USED TO ESTIMATE ILD'S FOR SELECTED INTERSECTIONS. A MODEL FOR ESTIMATING ILD'S FOR ANY GENERIC INTERSECTION BASED UPON A TRACE CONCEPT WAS DEVELOPED. ADESCRIPTION OF HOW THE RESULTS FROM THE DRIVING EXPERIMENTS CAN BE APPLIED TO HIGHWAY AND TRAFFIC ENGINEERING PROBLEMS IS PART OF THE REPORT. /FHWA/
