      <title>The Effect of Location, Mobility and Socio-Demographic Factors on Task and Time Allocation of Households</title>
      <link>https://trid.trb.org/View/805626</link>
      <description><![CDATA[Although several factors have been identified that influence interpersonal, within-household interactions, no study has yet investigated the role of location factors in within-household interactions in time use and activity participation.  This study investigates the role of location factors in task and time allocation at the household level. It is hypothesized that, if time constraints are less binding as a result of living in an urban area or owning more cars, spouses engage more often and longer in out-of-home activities and schedule their activities more independently. The hypotheses are tested with logistic and Cox regression models of activity participation and time allocation on a data set collected in the Amsterdam–Utrecht region in the Netherlands. The findings confirm the hypotheses that individuals engage more often in and allocate more time to work, personal business and out-of-home tasks in situations of fewer constraints.  Intrapersonal tradeoffs occur less frequently when space-time constraints are less binding.  The findings also suggest that with fewer constraints, activity choice and duration are more independent between spouses.  In most cases, this implies that women's activity schedules are more independent from males' activities in higher-density settings.]]></description>

      <title>A Multiple Discrete-Continuous Model for Independent- and Joint-Discretionary-Activity Participation Decisions</title>
      <link>https://trid.trb.org/View/794576</link>
      <description><![CDATA[Analysis of household interdependencies in activity-travel patterns is a growing area of research.  This paper contributes to this analysis by examining solo and joint discretionary activity participation (time use) decisions.  A multiple discrete-continuous econometric structure is used to model the daily time-investment decisions of couples in solo- and joint-discretionary activities incorporating intra-personal and inter-personal inter-dependencies. The empirical model was estimated using data from the 2000 Bay Area Travel Survey. The findings show evidence of the positive impact of vehicle availability on independent activity participation and the negative impacts of the presence of children and mandatory time investments on the joint discretionary-activity engagement of the spouses. In addition, results show that mandatory- and maintenance-activity-participation characteristics of the spouse influence the discretionary activity choices of individuals. The analysis also indicates a strong impact of common unobserved factors on the decisions of couples. Overall, these findings underscore the importance of explicitly incorporating intra-household interdependencies in transportation policy evaluations.]]></description>

      <title>Couple Similarity for Driving Style</title>
      <link>https://trid.trb.org/View/782743</link>
      <description><![CDATA[Though gender differences in driving habits and behaviors are well documented, the similarity between couples for such behaviors has received little or no attention. This study examined the associations between 413 pairs of intimate partners who completed the multidimensional driving style inventory, a self-report scale which assesses four broad domains of driving style. Significant associations were found between couples’ driving styles. Moreover, significant correlations were found between self- and partner-reports, indicating a high reliability for self-report in this context. The discussion focuses on the importance of examining intra-familial associations in driving styles as a basis for planning and designing effective safety interventions.]]></description>
