Shoulder width: The width of shoulders on State and rural roads, in feet.

Speed limit: Speed limit is an attribute of State roadway data. Segments that did not contain a speed limit, and not field verified, were assigned 25 mph within Boroughs or residential developments and 35 mph within Townships.

Functional Classification: The Federal Highway Administration classifies roadways by how they function in the transportation system. Each class is based on the type of service it provides, considering access, mobility, and location.

Bicycle Infrastructure: Road segments of the County that contain bicycle infrastructure, like sharrows, or the protected paths along Lefever Street and the North Gettysburg Trail along Old Harrisburg Road.

Sidewalks: While sidewalks are not necessarily meant for bicycles, or allowed like in parts of Gettysburg Borough, points were given to those roadway segments with sidewalks to distinguish borough and residential development settings where smaller children or families may feel more comfortable riding on a sidewalk.
