Empirical Case Study of Student Travel Demand Based on Spatial-Temporal Activity Population

초록

This study uses the spatial-temporal activity population approach to estimate and validate hourly travel demand for individual buildings. A case study models the spatial-temporal activity for students at North Carolina State University. To validate the results field survey provides observations of student in-and-out trips for dynamic, time varying ‘Class/Study’ activities at individual buildings. The travel estimates by activity-based approach are compared to the ones by conventional approach. Results show that the spatial-temporal activity presence approach provides reliable estimates of travel demand against the conventional approach at individual building level. This empirical case study should improve acceptance of the spatial-temporal activity procedure for activity travel demand, and demonstrate its value for other planning applications.
