                            <p>Due to the increase in developing levels of the populations, development levels, and depending on the number of people travelling with the number of vehicles, the energy demand in the world is increasing. Due to the limited of Turkey&#039;s energy sources, it is necessary to meet the continuous growing energy demand and consumption. Turkey, petroleum and liquid fuel imports with energy demand and consumption. The establishment of energy-related demand and consumption models is an important step. In this study, with a solid regression analysis of regression analysis technique approaches, Turkey&#039;s energy demand has been evaluated. In all methods, the best method has been determined that the quantile regression of 0.50. According to the OLS method, ton-km, vehicle-km, passenger-km and oil price variables have been determined the ratio of determination of transport energy to be 85,6%. When the quantile regression of 0.50 method is applied, it is seen that ton-km, vehicle-km, passenger-km and oil price variables have been determined the ratio of determination of transport energy to be 90,5%.</p></trans-abstract>

Türkiye’nin enerji kaynaklarının sınırlı olması sebebiyle, sürekli artan enerji talebini ve tüketimini karşılaması gerekmektedir. Türkiye, petrol ve sıvı yakıt ithalatı ile enerji talebini ve tüketimini karşılamaktadır. Enerji ile ilgili talep ve tüketim modellerinin kurulması önemli bir adım olarak karşımıza çıkmaktadır. Bu çalışmada, regresyon analizi tekniği yaklaşımlarından olan sağlam regresyon analiziyle, Türkiye’nin ulaşıma enerji talebi değerlendirilmiştir. Tüm yöntemler içinde, en iyi yöntemin Kantil regresyonu 0.50 olduğu belirlenmiştir. EKK yöntemine göre, Ton-Km, Araç-Km, Yolcu-Km ve Petrol fiyatı değişkenlerinin ulaşım enerjisini açıklama oranının %85,6 olduğu belirlenmiştir. Kantil regresyonu 0.50 yöntemi uygulandığında, Ton-Km, Araç-Km, Yolcu-Km ve Petrol fiyatı değişkenlerinin ulaşım enerjisini açıklama oranının %90,5 olduğu görülmektedir.</p></abstract>
