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...
The analysis proceeds with a review of the problem of forecasting transportation requirements. Several idiosyncratic models are examined and their properties specified. The forecasting of transportation stocks and commodity flows is discussed. Models of the demand for transportation services are implemented with empirical data. Graph theory as an interpretative frame of reference is introduced ...
This paper studies the crew planning problem as observed in the transportation industry. We first survey the existing literature on crew scheduling applications in railways and airlines. Next, we identify the synergies in the two domains and propose new directions for railway crew scheduling inspired from the applications in airlines.
In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...
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...
In recent years, there have been requirments for a transport environment that will foster comfortable and safe town development. Studies on urban activities in aging societies with falling birthrates and effective use of public transport modes in addressing environmental problems have become particularly important issues. Public transport is of great importance, especially from the perspective ...
Currently, road transportation is the main mode of freight transit in Iran and about 90% of freight transit is done through this mode of transportation which is not in line with the transportation policies that based on them 70% of the freight transit should be done through road transportation and 30% of the freight transit should be done through rail transportation. However, Iran's railway net...
In this paper, a planning problem is analysed for a consolidation transportation system in order to serve different transportation requests (i.e., orders) with different origins and destinations and different characteristics. The considered transportation system is a railway network provided with innovative terminals (where handling operations are realized very much faster than in traditional t...
Abstract. We present a game-theoretic model for the line planning problem in public transportation, in which each line acts as player and aims to minimize a cost function which is related to the traffic along its edges. We analyze the model and in particular show that a potential function exists. Based on this result, we present a method for calculating equilibria and present first numerical re...
