بخش حمل ونقل در اقتصاد هر کشور اهمیت خاص خود را دارد که با گستردگی فعالیت های اقتصادی و افزایش تولید ملی نیاز به توسعه و بهبود شبکه های حمل ونقل به خوبی احساس می شود. بر این اساس هدف از این مطالعه بررسی عوامل موثر بر جابجایی مسافر در ایران و پیش بینی تعداد مسافر جابه جا شده توسط حمل ونقل ریلی است. این کار تحقیقی برگرقته از مطالعه چن در سال 2007 میلادی است. متغیرهای مورد استفاده در این تحقیق، ت...
Comprehensive transportation Channel is the backbone of the regional transport system. The Channel structure configuration is a direct means of adjusting channel development state to meet the needs of traveler. By using fundamental analysis of the affecting factors and mechanism of passenger structure evolution within comprehensive transportation Channel, this paper presents a model on the basi...
This article focus on Cybernetic Transport Systems (CTS) due to their effectiveness for solving mobility problems in cities. A new mobility concept is proposed which allows to attain the same flexibility of the private passenger car but with much less nuisances. It is based on small semiautonomous electric vehicles, which may be used to complement mass public transportation, by providing passen...
Study on search algorithm of passenger travel route in railway transport network is of great importance in evaluation on railway operation benefit. Based on features of large-scale network and railway passenger transportation organization, the paper firstly innovatively puts forward the generation method of alternative route set in multiple constraint conditions. K short routes is proposed base...
This research presents a method of comparing fixed-route transportation systems and demand-responsive feeder transit systems using passenger survey data, published transit schedules, and optimal routing techniques. Demand-responsive transportation can be utilized to improve transit service levels in low demand areas. Since cities can vary significantly in demand across the region and time of da...
This paper deals with disruption management in passenger railway transportation. In the disruption management process, many actors belonging to different organizations play a role. In this paper we therefore describe the process itself and the roles of the different actors. Furthermore, we discuss the three main subproblems in railway disruption management: timetable adjustment, and rolling sto...
This work is part of an ongoing effort to understand the dynamics of passenger loads in modern, multimodal transportation networks (TNs) and to mitigate the impact of perturbations. The challenge is that the percentage of passengers at any given point of the TN that have a certain destination, i.e. their distribution over different trip profiles, is unknown. We introduce a stochastic hybrid aut...
In this paper, we give an overview of state-of-the-art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to solve them. We do not only consider classical, well-known topics such as timetabling, rolling stock sched...
Over the last decades we verified a huge intensification of human, financial, resource and power flow throughout the world economy. This phenomenon, called as globalization, affects goods and passenger movement, and demands the availability of connections, such as communications and transportation, providing citizens wider options and mobility. Nowadays there is a saturation of transportation i...
Many of the existing methods for evaluating an airline’s on-time performance are based on flight-centric measures of delay. However, recent research has demonstrated that passenger delays depend on many factors in addition to flight delays. For instance, significant passenger delays result from flight cancellations and missed connections, which themselves depend on a significant number of facto...
