OP-17: Employee Commute Modal Split

The percentage estimates provided above are based on the Make My Trip Count (MMTC) regional transportation survey results for the University of Pittsburgh main campus in Oakland. These results indicate the primary mode of travel to and from campus, and do not include multi-modal trips or people who use different modes throughout the week (such as someone who usually drives, but takes the bus sometimes).

Our total population of employees and students at the main campus when the MMTC survey was administered was 40,894. 2,679 people* (7%) responded to the MMTC survey. This sample size provides us a 95% confidence level** and a 2% margin of error***. The confidence level and margin of error were calculated using SurveyMonkey's Sample Size Calculator: https://www.surveymonkey.com/mp/sample-size-calculator/

The University receives total transit trip data from Port Authority of Allegheny County, but at this time cannot distinguish between student and employee travel. We hope that future technology advancements will allow us to distinguish between employee and student ridership counts.

According to MMTC, the mode split for the University of Pittsburgh main campus is as follows:
Drive Alone: 38.6%
Carpool: 4.8%
Vanpool: 0.9%
Dropped off: 2.6%
Bus: 34.3%
Light Rail: 2.3%
Park and Ride: 3.0%
University Shuttle: 0.7%
Bike: 5.1%
Walk: 7.2%
Telecommute: 0.2%
Other: 0.3%

For the purposes of this reporting, the following adjustments were made to the MMTC category results:
- The "Take a campus shuttle or public transportation" category also includes people who use Park and Rides, accounting for approximately 3% of our total campus population.
- The "Vanpool or carpool" category also includes people that reported being dropped off at work, approximately 2.6% of our total campus population.
- Our permit records indicate about 2% of our total employee population commutes to campus using a motorcycle, scooter, or moped. Since individuals using these types of vehicles would also most likely be driving alone, we removed 2% from the "drive alone" category (originally 39%) to avoid double counting.

* MMTC results can not distinguish between student and employee responses.
** Confidence Level: The probability that our survey sample accurately reflects the behaviors of the entire population.
*** Margin of Error: The range, measured as a percentage, that the total population's behaviors might deviate from our sample responses.
