Comparison to UNC Commuting Survey Results[1]Data from recent travel behavior surveys for UNC employees can be compared to TMP data to further explore commuting patterns. The top residential locations for UNC employees are generally similar to TMP employees, though a slightly higher percentage of TMP employees reside in Chapel Hill, and a slightly higher percentage of UNC employees live in Alamance or Chatham Counties.

TMP employees are less likely to live within 5 miles of their work than UNC employees. TMP employees are also less likely to live more than 20 miles from their work. Though travel time data is not directly comparable due to different categories for time, it is notable that UNC employees are less likely to commute less than 10 minutes (3.5% of employees, as compared to the TMP’s 14.5%). This seems to reflect the fact that UNC employees are more likely to use alternative modes, since modes such as transit have higher travel time than automobiles.

Mode choice for TMP employees and UNC employees is very different. Only 68.7% of UNC employees drive alone, compared to 89.3% of TMP employees. UNC employees are much more likely to use park-and-ride or other transit than TMP employees, and a higher percentage of UNC employees use all alternative modes. This can be attributed to the limited parking available on the UNC campus, and the extensive transportation demand management (TDM) programs conducted by the university to overcome this shortage.
