Descriptive analysis of the UTRACS data was completed. This provided a better understanding of seniors' activity generati<strong>on</strong>, planning and<br />
scheduling behavior compared to younger adults.<br />
Task 3: Describing Seniors†Activity-Travel Planning Behavior<br />
Seniors participate in a diverse set of activities including work, pers<strong>on</strong>al, religious, healthcare, services, errands, discreti<strong>on</strong>ary, and shopping. Our<br />
analysis showed that more than thirty percent of seniors†out-of-home activities are related to shopping. We have developed a hazard-based<br />
durati<strong>on</strong> model that replicates seniors†inter-shopping durati<strong>on</strong>.<br />
Task 4: Tour Formati<strong>on</strong> Model<br />
UTRACS data was processed for map-matching. In this analysis, we have allocated GPS traces to actual street network. The analysis allows us to<br />
observe individuals' tours that will be used to develop tour formati<strong>on</strong> models.<br />
Task 5: Mode Choice Model<br />
A preliminary mode choice model was developed using UTRACS dataset, however the results were not satisfactory due to small sample size of the<br />
dataset. It appears that we do not have enough number of observati<strong>on</strong>s of alternative travel modes (other than auto mode). We are c<strong>on</strong>sidering other<br />
data sources (e.g., CMAP's travel tracker data) for this analysis.<br />
Task 6: GIS Analysis<br />
As noted above (Task 4) a map matching algorithm was developed and used to allocate GPS data records to highway network. All other locati<strong>on</strong>s<br />
are also geo-coded.<br />
Task 7: Disseminati<strong>on</strong> of Findings<br />
We finished the manuscript <strong>on</strong> inter-shopping durati<strong>on</strong> analysis and will be sednding it to Transportmetrica journal. We will also present two papers<br />
in July in the Internati<strong>on</strong>al C<strong>on</strong>ference <strong>on</strong> Aging, Mobility and Quality of Life (AMQoL) in An Arbor, MI.<br />
Anticipated Work Next Quarter:<br />
We will finalize task 3 and will c<strong>on</strong>tinue working <strong>on</strong> Task 4 and 5.<br />
