AN EVALUATION OF THE PRIORITIES ASSOCIATED WITH THE PROVISION OF TRAFFIC INFORMATION IN REAL TIME

A STRUCTURED QUESTIONNAIRE WAS ADMINISTERED TO 732 DRIVERS RESIDING IN THE CHICAGO METROPOLITAN AREA. THE RESPONSES WERE USED AS A BASIS FOR DEVELOPING PRIORITIES FOR SCHEDULING IMPROVEMENTS IN THE HIGHWAY SYSTEM. SPECIFICALLY, THE PRIORITY OF PROVIDING TRAFFIC INFORMATION IN REAL TIME RELATIVE TO THAT OF MAKING ANY OTHER IMPROVEMENT IN THE HIGHWAY SYSTEM WAS EVALUATED. IN GENERAL, IT WAS FOUND THAT THE DRIVERS INTERVIEWED WERE QUITE CONCERNED WITH THE CONDITION OF THE PAVEMENT SURFACES ON BOTH EXPRESSWAYS AND CITY STREETS IN THE CHICAGO AREA. THE RESPONDENTS HAVING A LOWER INCOME, HAVING A LOWER EDUCATIONAL LEVEL, AND LIVING IN THE SOUTHERN PART OF CHICAGO WERE MORE CONCERNED WITH IMPROVING THE PAVEMENT CONDITIONS THAN WERE THEIR COUNTERPARTS. INFORMATION ON TRAFFIC CONDITIONS SEEMED TO BE RELATIVELY IMPORTANT TO EXPRESSWAY DRIVERS BUT UNIMPORTANT TO CITY STREET DRIVERS. THE PROVISION OF MOTORIST-AID PHONES WAS GENERALLY DESIRED FOR EXPRESSWAYS BUT NOT FOR CITY STREETS. THE PROVISION OF ADDITIONAL RADIO TRAFFIC REPORTS HAD VERY LOW PRIORITY. /AUTHOR/
