Title:

AN ANALYSIS OF DRIVER PREFERENCES FOR ALTERNATIVE VISUAL INFORMATION DISPLAYS

Accession Number:

00223286

Record Type:

Component

Abstract:

SEVERAL TRAFFIC INFORMATION DESCRIPTORS HAVE BEEN EVALUATED AS TO HOW DESIRABLE THEY ARE TO DRIVERS RESIDING IN THE CHICAGO METROPOLITAN AREA. THESE DESCRIPTORS ARE MESSAGES ABOUT THE CONDITIONS ON A FREEWAY AND ARE DISPLAYED BY ELECTRONIC SIGNS. EVALUATED WERE 7 DESCRIPTORS AT THE LEVEL OF HEAVY CONGESTION, 6 AT THE LEVEL OF MODERATE CONGESTION, AND 6 AT THE LEVEL OF NO CONGESTION. THE MESSAGES CONTAINED DESCRIPTIVE INFORMATION, QUANTITATIVE INFORMATION, AND NO INFORMATION. FOR ALL LEVELS OF CONGESTION, TRAFFIC INFORMATION WAS PREFERRED TO NO INFORMATION ABOUT TRAFFIC CONDITIONS. FOR THE LEVEL OF HEAVY CONGESTION, INFORMATION ABOUT AN ACCIDENT HAVING OCCURRED AND CAUSING HEAVY CONGESTION WAS THE DESCRIPTOR MOST PREFERRED BY RESPONDENTS IN THE TOTAL SAMPLE. THE SPEED DESCRIPTOR RANKED SECOND (THE ACCIDENT DESCRIPTOR RANKED FIRST) FOR THE LEVEL OF HEAVY CONGESTION AND FIRST FOR THE OTHER TWO LEVELS OF CONGESTION. THE TWO REMAINING DESCRIPTORS (EXCLUDING THE ACCIDENT DESCRIPTOR) WERE SCALED FAIRLY HIGH, BUT WERE LESS DESIRABLE THAN THE SPEED DESCRIPTOR. THE TWO QUANTITATIVE DESCRIPTORS, DELAY AND TRAVEL TIME, HAD RELATIVELY LOW SCALE VALUES AND WERE SIMPLY NOT DESIRED BY THE RESPONDENTS. /AUTHOR/
