Transportation System and Performance 3 The Multimodal Transportation System—Its Use and Performance The transportation system includes all of the facilities and services that enable people to travel, ship goods, and provide services. This chapter inventories all modes found in Cambria County: • highways, bridges and traffic signals and signs – see page 20 for highways, page 41 for bridges, and page 48 for signals and signs • public transportation services – see page 50 • air travel facilities and services – see page 58 • rail infrastructure and services for freight and passengers – see page 61 • facilities for bicyclists and pedestrians – see page 64. More importantly, the chapter discusses the use, condition, and performance of these facilities and services as PennDOT and the County increasingly manage maintenance and improvement funds based on these metrics. Cambria County Long Range Transportation Plan, 2015-2040 19 Transportation System and Performance 3 Highway Network: Classifications and Volumes Summary Statistics Of the 1,700 linear miles of roadway in Cambria County, roughly 60 percent of roads in this area are locally owned by municipalities, but state-owned roads carry 88 percent of all traffic. See Table 3-1.

These highways are selected by PennDOT and local officials and subject to approval by the Federal Highway Administration and are eligible for financial assistance for their construction, maintenance, and operations through the Federal- Aid Highway Program. The Federal-Aid System in the County includes all National Highway System (NHS) highways plus portions of several state and local highways totaling more than 447 state-owned miles and 25.9 locally-owned miles. See Table 3-2. Total mileage of the Federal-Aid System has not changed over the past five years.

The National Highway System includes the Interstate System, the Strategic Highway Network, and highways serving major airports, ports, rail or truck terminals, railway stations, pipeline terminals, and other strategic transport facilities. The National Highway System receives dedicated funding that cannot be used on non-NHS highways. Elements of the National Highway System within the County include US 22, US 219, US 422, and PA 56, and portions of PA 271 totaling 126 miles. See Figure 3-1 and Table 3-3. Over the past five years, there has been no significant change in total mileage of the NHS in the region.

They can be grouped or ranked in terms of the proportion of mobility vs. access they provide—a concept known as highway functional classification. The Federal Highway Administration, PennDOT and Cambria County use functional classification in determining eligibility for funding under the Federal-aid program. The Federal Highway Administration prescribes three functional classifications with various sub-classifications and determines the classification of each state- and locally-owned highway by segment. Arterials are highways that connect, as directly as practicable, the nation’s principal urbanized areas, cities, and industrial centers; serve the national defense; and connect at suitable border Cambria County Long Range Transportation Plan, 2015-2040 21 Transportation System and Performance 3 points with routes of continental importance. All arterials are eligible for Federal-Aid funding. Arterials are sub-classified into four groups: • Interstates are the highest classification of arterial roads characterized by divided, directional lanes offering the highest level of mobility, at the highest speed, for long uninterrupted distances. There are no interstates in Cambria County. • Other Freeways and Expressways often but not always have divided directional travel lanes and access limited to grade-separated interchanges or a very few at-grade intersections. Portions of US 22 and US 219 and PA 56, the Johnstown Expressway, are classified as other freeways/expressways. • Other Principal Arterials provide high mobility in urban areas and between rural centers. They may be limited access or provide direct access to abutting lands. Remaining portions of the US routes and many PA 2- and 3-digit routes in Cambria County are principal arterials. • Minor arterials typically interconnect other arterials and collectors for long-distance trips. In Cambria County, these include about a dozen 2-, 3- and 4-digit state routes. Collectors provide land access service and traffic circulation within As federal and state transportation residential neighborhoods, commercial and industrial areas, and agencies continue to move toward a downtown city centers. Collectors connect local roads and streets performance-based management with arterials and provide less mobility than arterials, at lower speeds approach, they may also measure, and for shorter distances. They may be sub-classified as major develop benchmarks, and set collectors in higher density developed areas and minor collectors in performance targets by functional classification. lower density developed areas. Major collectors are eligible for Federal-Aid funding; minor collectors are not.

In functional classification, “local” indicates the facility’s function, not its ownership. All highways not classified as arterials or collectors are deemed locals. Locals are not eligible for Federal-Aid funding. PennDOT posts highway network maps of functional classification by county on the Bureau of Planning and Research webpage here. Highway mileage by classification is shown in Table 3-4.

Other principal arterials carry the largest percentage (24.2 percent) of daily vehicle- miles traveled (DVMT) followed closely by freeways/expressways at 23.6 percent. Major collectors rank a close third, carrying 20.1 percent of total traffic. These Federal-Aid eligible highways total 27.2 percent of the network and carry 83.5 percent of its traffic. Minor collectors and locals total 72.8 percent in length and carry 16.5 percent of total traffic. See Table 3-5.
