TIVE DATE
W~-~REAS, proper driveway access demgn and location are essentml to the maintenance of safe and
efficient traffic flow,
W~-~RF_,AS, m order to prevent the probfemtion of poorly spaced driveways, driveway access deign
polil~es, that can improve safety and maintain carrying capacity of pubhc roadways, should be promul-
gated to apply Jo all properties for which a land use or property boundary change is propom~d;
~r.~REAS, the impact of driveways on t~ safety and roadway canymg capacity makes ~t apparent
tha~ it ~s m the b~st interest of a community to have a driveway access pohcy which habits the number
of d~veways Io safely accommodate the traffic generated by each property, provides adequate spacing
bemeen adjacent dnveways or adjacent streeJs to reduce acc~ent potential and ensure proper geo-
me~c design to promote traffic safety and enhance the capacity of the roadway,
WI-~REAS, drrveway location and design nupacts tr~c safety;
WIgAn. AS, noht turns into and out of driveways, requumg only a speed change, a merge or demerge,
anda turn which may cause an encroachment on an adjacent travel lane, have the least LmpaCt on traf-
fic ~mfety;
WHEREAS, left turns, requiring a speed change, merge or demerge, and the crossing of opposing traf-
fic, eause more conflicts,
WHEREAS, adequate dnveway spacing promdes enough roadway for motor vehicles to make turns at
ad~-'ent drives such that acceleralien - deceleratien areas do not overlap, and
WHEREAS, the potential for accidents increases when dnveway spacing decreases to the point where
speed change and merge areas begin to overlap for turning movements at adlacent dnveways;
NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF COLLEGE STATION,
