DATA REQUIREMENTS FOR METROPOLITAN TRANSPORTATION PLANNING

URBAN TRANSPORTATION STUDIES HAVE COLLECTED SUBSTANTIAL DATA ON LAND USE, TRAVEL, TRANSPORTATION FACILITIES AND SOCIOECONOMIC CHARACTERISTICS. IT HAS BEEN ALLEGED THAT THE COLLECTION OF THESE DATA IS EXCESSIVELY COSTLY AND TIME-CONSUMING. IN VIEW OF THE EVOLVING NATURE OF THE TRANSPORTATION PLANNING PROCESS, A REEXAMINATION OF DATA REQUIREMENTS AND COLLECTION TECHNIQUES HAS BEEN NEEDED. WHAT DATA SHOULD BE GATHERED IN THE FUTURE? WHAT SHOULD BE A TRANSPORTATION STUDY'S POLICY ON DATA COLLECTION? IN THE RESEARCH REPORTED HERE, FIVE REPRESENTATIVE TRANSPORTATION STUDIES WERE EXAMINED IN DETAIL TO REVEAL THE KINDS OF DATA NEEDED, TO DETERMINE THE COSTS OF DATA COLLECTION, AND TO CHECK THE DEGREE OF USE OF THE COLLECTED DATA. FOUR RELATED KINDS OF PLANNING (COMPREHENSIVE METROPOLITAN LAND USE PLANNING, HIGHWAY ROUTE SELECTION, TRANSIT PLANNING, AND TOPICS) WERE EXAMINED TO DETERMINE THE RELATIONSHIPS OF THEIR DATA REQUIREMENS TO THOSE OF THE TRANSPORTATION PLANNING PROCESS. THE SENSITIVITY OF THE TRANSPORTATION PLANNING PROCESS TO DATA ERRORS WAS STUDIED TO DETERMINE THE AMOUNT OF DATA NEEDED, OF EACH TYPE. ALTERNATIVE DATA COLLECTION TECHNIQUES WERE EXAMINED TO SEE WHETHER OTHER TECHNIQUES COULD OBTAIN DATA MORE EFFICIENTLY AND AT A LOWER COST. AN EXAMINATION OF SAMPLING RELIABILITY WAS UNDERTAKNE. THE FINDINGS FROM THESE SEPARATE STUDIES WERE THEN INTEGRATED AND A SUGGESTED DATA COLLECTION POLICY WAS PREPARED. THE MAIN FOCUS OF THIS WORK WAS THE STRATEGIC TRANSPORTATION PLANNING PROCESS (STPP). THE STPP IS DEFINED AS THE PROCESS OF DETERMINING A RECOMMENDED LONG-RANGE LEVEL OF INVESTMENT IN TRANSPORTATION, THE DIVISION OF INVESTMENT BETWEEN MAJOR MODES OF TRAVEL, THE LOCATION OF CORRIDORS FOR EXPRESSWAYS AND RAPID TRANSIT FACILITIES AND THE GENERAL SEQUENCE OF INVESTMENT. THE STPP IS THE CORE OF THE URBAN TRANSPORTATION PLANNING PROCESS; IT DEFINES THE SYSTEMS OF MAJOR FACILITIES THAT WILL SERVE AS THE FREAMEWORK FOR LESSER TYPES OF IMPROVEMENTS AND FOR MORE DETAILED, IMPLEMENTATION PLANNING. /HRB/
