Criteria for determining classifications shall be as follows:
A. Major or principal through street or highways. (See Figure
1.)
(1) The proposed street or highway is the direct and logical
continuation of an existing street highway that carried 1,000 or more heavy
and light vehicles during a twelve-hour period as shown on the latest traffic
count.
(2) The proposed street or highway creates a shorter and
more convenient through-traffic artery so that it can be reasonably expected
that traffic will be diverted from other major streets or highways to such
an extent that it will reach at least 1,000 cars in 12 hours two years after
opening.
(3) The proposed street or highway could logically be expected
to become a major street or highway because of future construction or other
foreseeable circumstances.
B. Commercial or light industrial streets or highways. (See
Figure 2.)
(1) The proposed street or highway is in an area zoned for
commerce or light industry.
(2) The proposed street or highway is on or so close to the
dividing line between a residential and commercial or light industrial area
that it may reasonably be expected to carry a substantial volume of heavy
vehicles.
(3) The proposed street or highway creates a shorter and
more convenient route between a commercial or light industrial area and a
major traffic artery.
(4) The proposed street or highway for any other reason may
be expected to carry a substantial volume of commercial or light industrial
traffic.
C. Rural or suburban streets or highways. (See Figure 3.) This classification is intended to cover the majority of residential
subdivision roads.
(1) The proposed street or highway shall not be or be reasonably
expected to become a principal through, commercial or industrial street or
highway.
(2) The proposed street or highway shall be a deadend, loop
or other main street or highway within a residential development or residential
neighborhood.
(3) The proposed street or highway does not or cannot reasonably
be expected to carry such a substantial volume of traffic as to require its
construction in accordance with major or principal through road standards.
D. Rural streets (private). (See Figure 3a.) This classification is intended to cover proposed residential
subdivision streets serving eight or fewer lots or dwelling units, which streets
are proposed to remain under longterm private ownership and maintenance responsibility.
