The effects of the rawmaterral transportation from procuction units on the hisway

In Turkey, 92% of freight transport is realized on roads and highways. Today, the burden of that situation on country's economy is discussed and studies to shift freight transport to other modes are conducted. These countrywide studies lose their validity in urban scale. The transport relationship between production and comsumption places in our cities are also dependent to roads and highways. Among its reasons, the advantages of door-to-door transport together with lack of habidute of using other modes of transport are considered. That freight transport on roads and higways is seen as the only alternative even in the routes where railway alternative exists, brings the urban freight transport in Ankara to a point far from any solution. In this study, in the case of the transport relationship between the concrete centrals, the concrete factories and the stone quarries in Ankara, the structure of urban freight transport is examined. The data, wich were obtained through a detailed field research, show that in a comparison of highways versus railways, railways are not taken even in the agenda. In the final part of our study, some ideas to minimize and rehabilitate negative effects of freight transport in Ankara will be discussed.
