Truck freight dominates the freight transportation. Motorways are especially important in serving truck freight demand due to more reliable travel times and favorable driving conditions, and result in different mode and route choice behaviors. Thus, it is important to understand the characteristics of truck commodity flows on motorways, which is the objective of this study. In the absence of commodity flow data in Turkey, the major source of freight data is the roadside axle load surveys conducted annually by the Turkish General Directorate of Highways (TGDH). Unfortunately, these surveys do not include observations on/around motorways, except for the year 2005, when 6299 trucks were surveyed at 19 locations on three motorway corridors in Turkey (Northern corridor connecting Edirne-İstanbul-Ankara, Aegean Corridor of İzmir-Aydın and southern corridors connecting Adana-Şanlıurfa). The following data was collected for each surveyed truck: Origin-Destination (O-D), commodity type, truck type, payload and location information. s. Therefore, truck circulation characteristics on different motorways corridors were studied to observe corridor based differences in commodity types, truck types, payloads, loading conditions and O-D patterns. The three motorway corridors serve many O-D pairs in the national level. Differences among the corridors are expected due to differences in regional economics and industries, as well existence of ports and border gates. The motorways are developed as corridors and are not total connected, yet, which may restrict the national flows on some of them

Modeling of freight transportation on Turkish highways
Ünal, Leyla; Türel, Ali; Department of City and Regional Planning (2009)
Transportation planners are often faced with the problem of estimating passenger and freight flows between regions. In the literature there are many models for passenger flows. However, models about freight flows are more limited. Modeling freight flow is also more complex than modeling passenger flow and there are many agents related with freight flows. In addition, data availability is a critical factor. In this research, freight flows between provinces in Türkiye are forecasted by demand analysis. Transp...
Location–routing and synchronization problems in city logistics
Farham, Mohammad Saleh; Süral, Haldun; Department of Industrial Engineering (2020)
City logistics aims to improve urban freight transportation by considering the costs and benefits of public and private sectors, consolidating segmented freight shipments, and integrating the individual actors in a collaborative environment. This thesis studies network design problems in city logistics systems to address managerial challenges in urban freight transportation. We consider two network design schemes, namely the one and the two-echelon distribution networks, to formulate strategic and tactical ...
Modeling truck traffic in Turkey
Fayyaz, Muhammad; Tüydeş Yaman, Hediye; Department of Civil Engineering (2015)
The objective of this study is to contribute to intercity road freight modeling in Turkey in general, and particularly estimation of origin-destination (O-D) matrix for intercity truck traffic, using the available freight transport data. As commodity flow data is not available for Turkey, information collected through roadside axle surveys is the main data source of this study. Firstly, the survey matrix has been estimated using roadside axle survey data from 2007-2011 period, and enlarged using link counts...
Factors Affecting the Capacity Utilization of Road Freight Transport in Turkey
ÖZEN, MURAT; Fayyav, Muhammad; Tüydeş Yaman, Hediye (Teknik Dergi, 2020-03-01)
Road freight accounts for 89% of the inland freight transportation in Turkey. This study examined the factors affecting capacity utilization in Turkey with a specific focus on load factors and empty running. These two decisions, the load factor and the choice of running empty, are modeled jointly in a Heckman model. The model results showed that rigid and articulated trucks represent relatively different transport markets. Their age and the distance profile of the shipments affect the load factor and the pr...
