in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

This paper studies the modeling theories and simulation methods for railway transportation system. The railway transportation system is a typical temporal-spatial dynamic system. Recently the method with temporal-spatial computation characteristics, Cellular Automata, is often used for road traffic flow research, but it’s homogeneity restricting make it impossible to modeling railway transporta...

after 1860’s the railway systems has started to be used in urban transportation in the world. however, especially after the 1950’s, automobile usage has been increased quickly. thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in istanbul. traffic density in urban transportation has started to be experienced since 1950 with the incre...

Making great strides in social economy, demands for the material is growing, at the same time,it also stimulates the development of logistics.The railway-water combined transportation of our country is being into a golden opportunity, With the support of national policy and the improvement of railway transportation capacity,it's preparing for the development conditions of the railway-water comb...

With the construction of high-speed railway lines in China, there are growing concerns about the rational transport cooperation between high-speed railway lines and conventional rail lines. A rational transport cooperation scheme can improve railway capacity utilization, train speed, service and the organization quality of railway transportation. The previous research mainly focused on the aspe...

A different intermodal transportation model based on cost analysis considering technical, economical, and operational parameters is presented. The model consists of such intermodal modes as sea-road, sea-railway, road-railway, and multimode of sea-road-railway. A case study of cargo transportation has been carried out by using the suggested model. Then, the single road transportation mode has b...

INTRODUCTION TRANSPORTATION of people is increasing as our society grows and the demand for railway services that can provide high-speed and high-capacity transportation is becoming greater. The number of train rides taken in Japan in 2006 was 22,243 million, more than anywhere else in the world by some margin, making Japan one of the world’s leading railway nations. A major feature of railway ...
