THE DESIGN OF CENTRAL BUSINESS DISTRICTS, WHERE A SUBSTANTIAL PORTION OF THE 1 BILLION SQ FT OF OFFICE FLOOR SPACE BUILT IN THE NATION DURING 1960-1970 HAS BEEN LOCATED, WILL BECOME INCREASINGLY IMPORTANT IN THE FUTURE. YET, TRADITIONAL TRANSPORTATION PLANNING STUDIES, INCLUDING ORIGIN-DESTINATION HOME INTERVIEWS, FAIL TO ACCOUNT ADEQUATELY FOR NON-HOME-BASED, ESPECIALLY PEDESTRIAN, TRAVEL WITHIN THE CBD. PEDESTRIAN FACILITIES ARE SELDOM DIMENSIONED IN PROPORTION TO THE TRIP GENERATION OF THE BUILDINGS THEY SERVE. AS A RESULT, PEDESTRIAN CONGESTION IN LARGE CENTRAL BUSINESS DISTRICTS IS QUITE COMMON. THIS STUDY, FOCUSED ON MIDTOWN MANHATTAN, FIRST RELATES PEDESTRIAN DENSITY TO WALKWAY SPACE AND BUILDING FLOOR SPACE AT TWO POINTS IN TIME. AVAILABLE WALKWAY SPACE AND BUILDING FLOOR SPACE IN RETAIL, RESTAURANT, AND OFFICE USE ARE FOUND TO AFFECT SIGNIFICANTLY THE PRESENCE OF PEDESTRIANS. ESTIMATING EQUATIONS ARE PRESENTED AND EVALUATED. THE DAILY CYCLICAL VARIATION AND DIRECTIONAL DISTRIBUTION OF PEDESTRIAN TRAVEL AT BUILDINGS WITH DIFFERENT USES AND AT SELECTED STREET LOCATIONS ARE GIVEN. RELATIONSHIPS TO DAILY TRIP GENERATION RATES AND THE RELATIVE MAGNITUDE OF DESIGN PERIOD FLOW ARE SUGGESTED. TRIP LENGTH CHARACTERISTICS ARE SHOWN FOR THE WALKING PORTION OF VARIOUS TRIPS AT THE CBD END AND ARE ANALYZED BY PURPOSE AND BY MODE. THE AVERAGE WALK IS FOUND TO BE ABOUT 1/3 OF A MILE, AND WALK-ONLY TRIPS ARE FOUND TO COMPOSE ABOUT 26 PERCENT OF TOTAL CBD TRIP ENDS. ALTHOUGH MANHATTAN REPRESENTS A LIMITING CONDITION WITH REGARD TO TRIP- END DENSITY AND TRIP LENGTH, THE FACTORS DERIVED REPRESENT A USEFUL INPUT INTO THE DEVELOPMENT OF DESIGN STANDARDS FOR PEDESTRIAN MOVEMENT. /AUTHOR/
