... 17 Transportation Networks Automobile, Bicycle, and Pedestrian Networks Automobile Network For decades, functional classification has relied upon three general thoroughfare types: arterials, collectors, and locals. More recently, arterials have been further subdivided into principal and minor, resulting in four classification types that are now in common use.

... 18 An Expanded Functional Classification System for Highways and Streets – Access to public transportation. – Pedestrian and bicycle movements.
From page 19...
... Transportation Networks 19 routes should be spaced at greater intervals than medium-separation-level routes, which are spaced at much greater intervals than low/no-separation routes. Spacing varies considerably for different areas.

... 20 An Expanded Functional Classification System for Highways and Streets to 15–20 miles (NHTSA 2002)
From page 21...
... Transportation Networks 21 However, in denser urban areas, pedestrian activity may also cross contexts or land use boundaries, necessitating the accommodation of pedestrian traffic through a context area to another major area of activity. For example, a corridor connecting a university campus with a downtown area may require enhanced sidewalks even if the context may not demand such treatment.
From page 22...
... 22 An Expanded Functional Classification System for Highways and Streets Efficiency of Travel Pedestrians typically seek out roadways (paths) that let them travel to their destinations along routes they perceive as safe and interesting.
From page 23...
... Transportation Networks 23 and routing plans for transit facilities as well as guides to aid in the design of transit facilities (AASHTO 2014)
From page 24...
... 24 An Expanded Functional Classification System for Highways and Streets or generation. For instance, a roadway in the urban core with heavy pedestrian-focused retail should place a high priority on pedestrian movement as it serves as the point of attraction.
From page 25...
... Transportation Networks 25 discussions with these stakeholders, aiming to identify the relative need for each facility within the respective network. This process can rely on CSS principles to define modal priorities and hence establish the network classifications for bicyclist and pedestrian facilities.
