Regional Characteristics

The modeling area covers the Harrisonburg MPO area which includes the City of Harrisonburg and part of Rockingham County, including the towns of Bridgewater, Dayton, and Mt. Crawford. The City of Harrisonburg comprises about two thirds of the current model region population. The Harrisonburg MPO area has the highest population density of any of the state’s small MPO areas and is the third highest in the state after Northern Virginia and Hampden-Roads . The Harrisonburg region is not in close proximity to any other existing model regions, with the nearest being Charlottesville.

Travel Characteristics

Centrally located in the Shenandoah Valley along the I-81 Corridor, Harrisonburg is a small growing metropolitan area. The population of the City of Harrisonburg has increased by more than seven percent over the last seven years. The principal north-south transportation routes serving the area are I-81 and State Route 42 while US 33 is the major East – West route. The Harrisonburg area’s three major academic institutions: James Madison University, Eastern Mennonite University, and Bridgewater College are major trip generators with 19,000 students. Tourism created by Shenandoah National Park, Luray Caverns, and other nearby attractions is also an important factor affecting travel. Additionally, since Harrisonburg is the largest city and economic hub of the Shenandoah Valley it is experiencing steady growth due to continued economic development. The Harrisonburg MPO area is projected to grow significantly from 2015 to 2035 as population is forecast to increase 40% from approximately 81,000 to 111,000.
