AN ORDINANCE TO ESTABLISH AN ARTERIAL TRAFFIC PLAN FOR
I THE VILLAGE OF DUBLIN, OHIO
WHEREAS, the Village of Dublin has paid for and received a comprehensive traf-
fic study for rights-of-way and realignment and location of existing and future
streets, highways, and roadways, within the Village of Dublin, and
WHEREAS, the Village must develop a plan for a street system to preserve the
health, safety and welfare of the general public as well as to create a desir-
able environment and promote economic growth; and
WHEREAS, a uniformed functional street system classification may be used by the
private sector as a guide to likely future action respecting the development of
public streets, and
WHEREAS, the Village Administration, the Planning and Zoning Commission, the
Board of Zoning Appeals, and the Council require a traffic plan on which to
base decisions on zoning changes, variances, and conditional uses.
NOW, THEREFORE, BE IT ORDAINED by the Council of the Village of Dublin, State
of Ohio, 7 of the elected members concurring:
SECTION 1. That the text, attached hereto, titled "Dublin Traffic Plan" con-
tains the terminQlogy and description of the Villages' roadway network and the
I basic design elements for the Villages' street functional classification.
SECTION 2. That the Map titled "Village of Dublin, Ohio, Map Street Plan" be
and hereby is adopted by this Council as the minimum recQmmended standards for
rights-of-way and pavement construction.
SECTION 3. That the actual alignment of arterial streets along proposed corri-
dors will be determined by engineering feasibility studies of alternate pro-
posals or will be determined by land use patterns as they develop.
In developed areas where no right-of-way has been acquired for future widening,
the stated minimum right-of-way may not apply. Any additional right-of-way
and pavement required for such roadway will be determined at the time a roadway
improvement is recommended, and on the basis of public concerns. For such road
ways the arterial type shall serve as a fURctional classification of the roadwa .
SECTION 4. That the Village Administration, the Planning and Zoning Commission
the Board of Zoning Appeals or the Council shall cause a review of the arterial
and their eonstructioR types to be made at such time as there is belief that
living, employment or traffic patterns have changed sufficiently to warrant
such, but in no case at longer intervals than four (4) years, and shall submit
proposed changes in the form of an amendment to this ordinance.
SECTION 5. That this Ordinance shall take effect and be in force from and afte
the earliest period allowed by law.

Freeways
The intent of urban freeways is to carry large volumes of
traffic with minimum interruption to the freeflow of traffic
movements. Its function is to link major traffic generators
and provide continuity with the rural and urban freeway system.
Principal Arterials
The primary function of principal arterials is to move large
volumes of traffic between major centers of activity. Its
secondary function is to serve adjacent properties, however,
this should be minimized so as not to materially disrupt
flow of traffic. Additionally, it serves as feeder to the
I freeway system.
Minor Arterials
The primary function of minor arterials is to provide for move-
ment of through traffic with the secondary function to pro-
vide access to abutting lands.
.
l-

Minor arterials are fed traffic by collectors and other minor
arterial streets and in turn feed principal arterials or free-
ways. In order to properly perform the primary functions they
are normally spaced about one (1) mile apart and intercept
I collector streets at intermediate points. Ideally they pro-
vide continuity of travel routes and are relatively straight
roadways so as to encourage usage by through traffic.
Minor arterial traffic is given preferential traffic control
treatment by stopping streets of lesser importance. Traffic
signals also would favor the arterial street so as to mini-
mize stoppage. Intersecting collector streets should junc-
tion with the arterials at 1/4 mile increments so as to favor
future traffic signal networks.
Collector
The service function of collector streets is to collect
traffic from local streets and distribute this traffic to
the higher classified roadways. It equally serves to move
traffic and provide access to abutting lands. Tra ffic con-
trols would favor this street over local streets.
I Local
The main function of local streets is to provide access to
abutting lands. It serves to feed the collectors and minor
arterials. Through traffic is discouraged on this type of
street.
Street Design Elements
Spacing Between Street Classifications
In order to provide for equal distribution of traffic in a
suburban area the approximate spacing of the various classi-
fication of streets (distance between similar type streets)
has generally been found to be the most effective as follows:
I .-
,
Freeways 2 - 6 Miles
Principal Arterials 1 - 2 ttiles
Minor Arterials 1 - 2 Miles
Collector 1/2 - 1 Mile
Local 1/2 - 1/10 Mile

Design Pavement Widths
I The design width of various types of roadways is dependent
upon the roadway capacity requirements. One of the para-
meters in selecting the street classification is traffic
volumes which in turn directly influences the number of
lanes and right-of-way widths.
Border Areas
The border area is defined as the area in back of the curb
or pavement edge to the right-of-way line. This would in-
clude the grassed area between the pavement and sidewalk.
In undeveloped areas the desirable area width would be
10-12 feet. This area would provide for a utility strip,
sidewalk, bikeway (additional 8-12') and an area for sign
installations. In locations where curb and gutter require-
ments have been waived, then 8 foot berms and ditches would be
utilized requiring a border area of approximately 22 feet de-
I pendent upon the topography.
