According to analysis of infrared and manual trail counts along the 150-mile Great Allegheny Passage by economics professor Dr. Andrew Herr at St. Vincent College, trail traffic on the GAP increased 4.6 percent from 2018 to 2019, to an estimated 989,455 visits.  This increase is welcome news after the most rainy year on record in Pennsylvania (2018) curtailed travel for some tourists and local users.  Data from visitor centers along the GAP indicate that bicyclists, hikers, and runners arrived from all 50 states and over 35 countries.  

There are 12 infrared counters along the GAP, and manual counts performed by volunteers in the spring, summer, and fall verify the extent to which the infrared counters are working properly.  Observations by the volunteers indicate an estimated 63,213 overnight or thru-riders on the GAP in 2019.

The complete analysis is available here.
