Abstract

Abstract The path finding, called the Tree Building, is the main foundation on traffic assignment model. In conventional method, each iteration in route finding process can produce best path or shortest-path. On the contrary, on fuzzy travel cost condition, that process could produce several paths as shortest-path nominations. This paper discussed the route finding using fuzzy travel cost approach. In conventional method, travel cost, as an input in the model, is expressed in deterministic form, while in fuzzy cost, travel cost is represented as range of certain value from under-bound to upper-bound. Path finding process in fuzzy cost was developed based on Dijkstra (1959) algorithm which placed each selected route in certain layers. Layer with selected route is sequenced from “first” best route. This algorithm is named as Dijkstra Multi Layer (DML) Algorithm. At the end, flow assignment has done with calculating fuzzy membership value in each selected route toward to the best route.   Keywords: fuzzy route cost, shortest path, layer, Dijkstra Algorithm

Abstract

Abstract The road transport infrastructure investments have significant impact toward processing industry sector. The high cost of transportation will increase production costs and result in a lack of competitiveness of economic sectors in Indonesia. The purpose of this paper is tried to describe the contribution of road infrastructure investment to Processing Industry Sector in Bandung Regency (by empirical data). The role of infrastructure investment is a way to lower the cost of transportation of goods and increase accessibility among the connected region. The result indicates reduction of freight transportation cost for around 17% after the operation of Cipularang Toll road (+2% of marginal cost). Keywords: freight transportation cost, toll road investment, processing industry sector  Abstrak Investasi infrastruktur jalan akan mempengaruhi sektor industri pengolahan, dimana peran transportasi sebagai fungsi logistik mempengaruhi sektor produksi. Tingginya biaya transportasi dapat meningkatkan biaya produksi dan menyebabkan lemahnya daya saing sektor ekonomi di Indonesia. Penelitian ini mencoba mendeskripsikan kontribusi dari investasi infrastruktur jalan (Jalan Tol Cipularang) terhadap sektor industri pengolahan di Kabupaten Bandung. Peran dari investasi infrastruktur jalan adalah untuk menurunkan biaya transportasi dan meningkatkan aksesibilitas antarwilayah yang terhubung. Hasil penelitian menunjukkan pengurangan biaya transportasi barang di Kabupaten Bandung sebesar +17% sesudah beroperasinya Jalan Tol Cipularang (+2% dari total biaya produksi). Kata-kata kunci: biaya transportasi barang, biaya produksi, sektor industri pengolahan

Abstract

Strong interaction between landuse and transportation system has been well and widely known by many transport planners. However, this concept is rarely being used in many transportation network planning projects. The parameter usually used is the trend of traffic growth. This kind of information is not very precise to be used for the transportation network development policy. This kind of information will give misleading results for the transportation network development policy.Basically, this interaction concept combines the regional development policy represented in the Regional Landuse Plan (national, province, kabupaten or city) with the Transport Network System which will accomodate the flows resulting from the activities carried out by each landuse. In fact, the landuse has a very strong causal relationship with the transport network system (road, rail, etc.)A quantitive model has been developed to relate the interaction between the Regional Landuse Plan and the Transport Network System (especially road) so that the transport network development policy, in fact, has anticipated and accomodated the changes due to the landuse development. This quantitive model can be used for different levels of planning such as: for landuse (national, regional island, province, kabupaten, city and ecen small local area) and for road transport network (arterial, collector, local, either primary or secondary). This paper will describe in detail the interaction concept in the form of a quantitive model and show the results of the application for planning the development of road transport network in East Java province.
