Road classification systems define functions and present design criteria for different types of streets and roads. Get information and see interesting opinions on existing and alternative road classifications in terms of the way they impact CSS.
Excerpt

Urban Roadway Classification: Before the Design Begins
"The traditional classification systems have been based on the mobility and access functions of roads for motor vehicle traffic. Other road users and road uses have been largely ignored in this important step of the road design process. This article describes alternative classification systems..."
"Functional class and design speed don't have an automatic relationship. Functional classifications should be established with an eye to future planned development. There is a need for new classifications for scenic and historic country roads, with increased federal funding eligibility."

"A key concept expressed by staff from all [CSD] pilot states is to recognize the functional classification of the road or highway... [D]ifferent classes of facility serve distinctly different purposes on the highway network"
"Even after the decision has been made to functionally classify a highway section, there is still a degree of flexibility in the major controlling factor of design speed...It is [also] important to remember that there are no 'cookie cutter' designs for arterial highways or collector streets."
