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
