The following passage describes the
classification of roads in two countries.
Read the passage and make notes in the
correct format with a title Functional Classification (FC) 1 –An FC 1
facility is any type of surface paved
road. These roads may include
surfaces consisting of bituminous
asphalt and aggregate, hot-mix
asphaltic concrete, porcine cement
concrete or some combination of
these types of improved surface
courses; generally overlaying an
aggregate base course of varying depths.
In some ways it can be said that
structured road networks have existed in
India for almost 5,000 years. The
Mohenjo-Daro urban settlement in the
Indus valley (estimated population
about 35,000) had a rectangular road
grid and a system of major and lesser roads. More recently the Nagpur Plan of
1943 proposed four classes of roads.
National highways are the roads which
would pass through states, and places
having national importance for strategic,
administrative and other purposes. State
highways are the roads which would be
the other main roads of a state. District
roads are the roads which would take
traffic from the main roads to the
interior of the district. According to the
importance, some are considered as
major district roads and the remaining
as other district roads. Village roads are
those which would link the villages to
the road system.
The U.S. DOT‘s Federal Highway
Administration (FHWA) classifies its
Nation‘s urban and rural roadways by
road function. Each function class is
based on the type of service the road
provides to the motoring public, and the designation is used for data and planning
purposes. Design standards are tied to
function class. Each class has a range of
allowable lane widths, shoulder widths,
curve radii, etc. The four major road
function classifications are : Interstates,
Other Arterials, Collectors, and Local
roads. The amount of mobility and land
access offered by these road types
differs greatly.
Interstate System is the highest
classification of roadways in the
United States. These arterial roads
provide the highest level of mobility and
the highest speeds over the longest
uninterrupted distance. Interstates
nationwide usually have posted speeds
between 55 and 75 mi/h. Collectors are
major and minor roads that connect
local roads and streets with arterials.
Collectors provide less mobility than
arterials at lower speeds and for shorter distances. They balance mobility
with land access. The posted speed limit
on collectors is usually between 35 and
55 mi/h. Other Arterials include freeways,
multilane highways, and other important
roadways that supplement the Interstate
System. They connect, as directly as
practicable, the Nation‘s principal
urbanized areas, cities, and industrial
centers. Land access is limited. Posted
speed limits on arterials usually range
between 50 and 70 mi/h.Local roads
provide limited mobility and are the
primary access to residential areas,
businesses, farms, and other local
areas. Local roads, with posted speed
limits usually between 20 and 45 mi/h,
are the majority of roads in the U.S.
