Examination of planting standards in urban pedestrian and vehicle circulation in Düzce example

Open and green spaces are important centers for important breathing and urban ecological sustainability of cities. Pedestrian and vehicle roads in the city are important plant corridors of the landscape, and ecological taxes also provide important contributions to the city. Trees, shrubs and bushes, ground covers and seasonal flowers on the roads are indispensable for green partitions. Vegetation of vehicle and pedestrian roads is a major factor in ensuring the continuity of green in the city. It also brings with it the restrictions arising from both the application and ecological resources of the planting done in this direction in the cities. Within the scope of this study, planting standards, plant species selections, planting spacings for D-100 Highway, Akçakoca Highway, 9 boulevards, 18 streets and 14 streets in and around the urban core of Düzce city were evaluated. In the first stage of the study, a criteria and scoring system was developed by making use of the literature and standards. In the second stage, the samples in the study area were scored according to this scoring system and triple grouped as very appropriate, appropriate and less appropriate. According to the data obtained, it was seen that while there were similar choices in terms of species selection in all boulevards, there were differences in terms of planting standards. As a result, criteria such as preferred plant type, distance between plants, plant height, crown width, under-crown height, tree trunk circumference and electrical-plate distance directly affect the function of roads actively used by both vehicles and pedestrians.
