Transportation,
which is one of the basic needs of people from the social point of view, is
provided through land, sea and air way. The most common of these is highway
transport. As well as shaping the urban space, the highways also determine the
development direction of the cities. Urban roads are important areas that
reflect the quality of urban space, where first impressions of the city are
formed. In today's conditions, highways are supported with plant designs in
terms of security, traffic control and aesthetic perception. Especially in big
cities, this subject is sensitive enough, but in small and medium sized cities,
these theories do not find enough places in practice. In metropolitan cities,
traffic jam negatively affected on people psychology, and these adverse effects
can be eliminated with planting designs made according to the technique. Highways
are public spaces where the intense interaction between people and the
environment. These places are important elements that provide the relationship
between constructions and green spaces. The fact that the highways are the
structural elements that outstanding, it necessary to make landscape
arrangements in terms of visual effect. In this study, present planting
design
of Zonguldak-Kozlu Highway (Milli Egemenlik Street) was evaluated within the framework of functional and
aesthetic perception principles, deficiencies were determined and suggestions
were made
to eliminate these deficiencies.
The study area,
cover the part of Zonguldak-Kozlu Highway which is 5.7 km long, starting from
the intersection surrounded by the entrance shopping centers, hotel and the
entrance of Bülent Ecevit University to the entrance of Değirmenağzı Tunnel. The
study was conducted by four stages. The literature research on the field and
the subject was completed in the first stage. In the second stage, a natural
and cultural landscaping inventory was created. In the third stage, the
environmental relations of the area was revealed and the method to be applied
in evaluations was explained. At this stage, the 5.7 km long highway has been
divided into 6 equal zones, each of which covers the road about 1 km in the
length, and has been evaluated in terms of planting design through land
observations, Google Earth satellite images and photographs. At the last stage,
suggestions were given to improve the functional and aesthetic qualities of
highway planting in the area.
The presence in
the Zonguldak Provincial Center has been influential in the selection of the
study area, including the location of important public places in the city and
the user density. Some deficiencies have been determined in the planting design
of the study area. The elimination of these deficiencies will provide
contributions to landscape in terms of aesthetics, as well as to regulate
traffic and provide road safety. Refuge
arrangements were found to be inadequate in terms of aesthetic and functional
aspects. Especially not effective enough for traffic control. The number of
species used at intersections that are in focus is quite small. Planting design
does not have visually impressive qualities. Some of the large green areas
along the roads have positive features in terms of planting design.
Functionally, however, fall
short of the expectations. It has been observed
that the planting species used are inadequate to provide slope stabilization.
It has been determined that some of the pavement do not comply with the
standards. Inadequate maintenance work is one of the reasons after the
application.
As a result,
applications that do not coincide with highway landscape design principles have
been observed in a significant part of the study area. It has been determined
that planting designs made at the focal points of the area may be regarded as
aesthetically effective in the perception of the urban space but are inadequate
in terms of traffic control and comfort. In planting designs, species resistant
to adverse climatic conditions such as drought, wind and frost should be
preferred in accordance with the ecological conditions of the area, tolerant to
dust and gas emissions. In addition, it is necessary to regularly care for
important sustainable urban green areas such as road circles to be planted with
effective design in terms of aesthetics and for sustainable applications. In
highway landscape planning, plant design is an important dimension. It is
necessary to comply with the principles laid out in scientific ways at all
stages, from the planning to the maitenance, to the success of the design. In
terms of ecological wishes and tolerance to environmental effects, plants
suitable for the conditions of the place should be preferred. Landscape
architecture as a profession discipline is an important actor in the planning
of highways and planting design. It is important for the municipality and other
governing units to receive support from landscape architects and related
disciplines in terms of sustainability of the applications.

açıdan insanların temel ihtiyaçlarından biri olan ulaşım kara, deniz ve hava
yolu aracılığıyla sağlanmaktadır. Bunların içerisinde en yaygın kullanılan ise
karayolu ulaşımıdır. Karayolları, kentsel mekânı da şekillendirdiği gibi,
kentlerin gelişme yönünü de belirlemektedir. Kent içi yollar ise o kent ile
ilgili ilk izlenimlerin oluştuğu, kentsel mekânın kalitesini yansıtan önemli
alanlardır. Günümüz koşullarında karayolları, güvenlik, trafik kontrolü ve
estetik algı açısından bitkisel tasarımlarla desteklenmektedir. Özellikle büyük
şehirlerde bu konuya gerekli hassasiyet gösterilirken, küçük ve orta ölçekli
şehirlerde bu teoriler uygulamada yeterince yer bulamamaktadır. Çalışma
alanında da bu eksiklikler tespit edilmiştir. Zonguldak İl Merkezi’nde bulunması,
çevresinde kentin önemli kamusal mekânlarının yer alması ve kullanıcı
yoğunluğunun bulunması çalışma alanının seçilmesinde etkili olmuştur. Bu çalışmada, Zonguldak-Kozlu karayolunun
(Milli Egemenlik Caddesi), mevcut bitkilendirme tasarımı işlevsel ve estetik
algı ilkeleri çerçevesinde değerlendirilmiş, eksiklikleri saptanmış ve bu
eksikliklerin giderilmesi yönünde öneriler geliştirilmiştir. Sonuç olarak,
çalışma alanının önemli bir bölümünde karayolu peyzaj tasarım ilkeleri ile
örtüşmeyen uygulamalar gözlenmiştir. Alanın odak noktalarında yapılan bitkisel
tasarımların kentsel mekânın algılanmasında estetik açıdan etkili
sayılabileceği, ancak trafik kontrolü ve konfor açısından yetersiz olduğu
tespit edilmiştir. Bitkilendirme tasarımlarında yörenin ekolojik koşullarına
uyumlu, toz ve gaz emisyonlarına toleranslı, kuraklık, rüzgar, don gibi olumsuz
iklim koşullarına dayanıklı türler tercih edilmelidir. Ayrıca karayolu
çevreleri gibi süreklilik gösteren önemli kentsel yeşil alanların estetik
açıdan da etkili tasarımlarla bitkilendirilmesi, yapılan uygulamaların
sürdürülebilir olması için de düzenli bakımının yapılması gerekmektedir.
