  1. Serving New Jersey’s Personal Mobility Needs: Mercer County With Walking, Bicycling, aTaxisand Trains

  2. Mercer County Overview • Population: 366,513 (12th most populous county) • Area: 225 sq miles • 861 pixels originating trips • We (Princeton University) are in Mercer County right now • Also, includes Trenton, capital of New Jersey

  3. Trips from Mercer County • Number of Trips: 1.4 million • Total Trip Miles: 22.6 million

  4. Intra-Pixel Trips • Number of Intra-Pixel Trips: 18.0 thousand • % of Total Trips: 1.2%

  5. Walk Trips • Number of Walk Trips: 82.9 thousand • % of Total Trips: 5.8% • Average Trip Length: 0.59 miles

  6. Train Trips • There are four train stations in Mercer County: Trenton, Princeton Junction, Princeton, and Hamilton • Number of Train Trips: 43.0 thousand • % of Total Trips: 3.0% • Average Trip Length: 38.0 Miles

  7. Largest bubble is 20.5 thousand

  8. aTaxi Trips • Number of aTaxi Trips: 1.29 million • % of Total Trips: 90.0% • Largest # of trips from a single pixel is 31.5 thousand • Princeton University Pixel

  9. Introduction to AVO Analysis • 4 parameters: • Time or DD: length aTaxi waits at station • Origin Area Type (Pixel or Superpixel) • Denoted p or sp • A superpixel consists of a 9 pixels and are only used if the total trip length is longer than 3 miles • Destination Area Type (Pixel or Superpixel) • CD: Number of common destinations • New destination added if: • Vector from origin to destination is the in the same half plane • Addition does not increase any individuals trip length by more than 20%

  10. Bubble Map of Top 100 Pixels in Mercer County by # of Trips • The areas correspond to AVO DD = 5 min, p -> CD = 1p minus ¾ so that the differences are clear • Large bubble is Mercer Community College, AVO = 1.62

  11. In the top chart blue represents passenger miles and red vehicle miles • Note that the AVO is highest in the morning rush, while miles are higher during the afternoon

  12. In the top chart passenger miles are blue and vehicle miles are red • Note that the AVO is still higher in the morning

  13. Points represent the top 60 pixels by # of trips • Outlier is Mercer Community College

  14. In Depth look at Princeton Train Station Pixel {199, 102} • The Princeton Train Station pixel is the sixth largest pixel by number of trips in Mercer County. It contains the Princeton Train Station and part of the Princeton University Campus, though in our data set few of the Princeton University employees are assigned to work in it.

  15. The red icon marks the Princeton Train Station Pixel • The area of a bubble is proportional to the number of trips made to that pixel from the Princeton Train Station Pixel • The largest bubble on the bottom is 365 trips • The top 200 destinations from the pixel are shown

  16. In the top chart passenger miles are blue and vehicle miles are red • Note that the AVO is still higher in the morning

  17. Train Arrivals

  18. Mercer County Community College • All trips made around 3 in the afternoon (right after schools ends) • 11th largest pixel in Mercer County • Leads to by far the highest AVO • 1.62 for p -> CD = 1p • 2.54 for p -> CD = 1sp
