Comparative analysis of daily travel/activity behavior for workers and non-workers
xiv, 196 leaves : illustrations ; 28 cm.
The objective of this research is to conduct a comparative
analysis between the daily travel/ activity behaviors of
workers and non-workers so as to provide a better
understanding of their different daily travel/activity
patterns as subject to temporal/ spatial and household
constraints. This study represents a step towards improving
the forecasting of travel/ activity behavior in urban areas
by providing a conceptual framework which explicitly
recognizes behavioral differences between the two groups.
The source of data for this study includes 5,232 households
and 22,553 trip records which were surveyed by the Bexar
County Metropolitan Planning Organization in San Antonio in
1990. To achieve the objective of this research, and
validate the hypotheses, the research methodology involves
the following steps: Methodology for the first hypothesis
involves the use of Pearson's correlation coefficient (r) for
measuring the strength of correlation between variables, and
Analysis of Variance to test not only the variability of the
observations within each travel/ activity group but also the
variability between the group means, based on F ratios.
Methodology for the second hypothesis involves cluster
analysis for a number of homogeneous daily travel/ activity
patterns, and comparative analysis of the z scores for the
general travel/activity patterns. Methodology for modeling
daily travel/ activity behavior involves the description of a
conceptual framework and conceptual structures for workers
and non-workers. The analysis results verify that workers
and non-workers exhibit significant differences in daily
travel/ activity behaviors in terms of total daily travel/
activity duration, main activity duration, trip generation in
the afternoon peak time between 4 and 6 p.m., travel modes,
vehicle occupancy, and travel/ activity sequences before and
after main activities. The conceptual framework provides the
causal mechanism between constraints and decision processes
of workers and non-workers for urban daily travel/ activity
behavior. In the framework, the differences between workers
and non-worker can be explained by the concept of the main
activities. The conceptual method can be used as a guideline
to analyze the impacts of alternative scenarios of problem
constraints such as temporal and spatial dimensions. This
study has a great potential for improving the forecasting of
travel/ activity behavior in urban areas, especially in
relation to the policy issues of transportation demand
