Call for Papers

The 9th International Conference on Railway Operations Modelling and Analysis (ICROMA)

(RailBeijing 2021)

Beijing, China,

November 3-7, 2021

 Aims of IAROR

IAROR was founded in 2005 and has currently more than 400 members. IAROR combines the expertise of academic and professional railway research with the aim of enhancing the quality of service for railway passengers and customers, improving the effectiveness and efficiency of capacity management, timetabling, traffic management and ensuring the safety of railway operations. IAROR stimulates innovative theoretical approaches, high-tech concepts, new technological developments and dynamic decision support systems that contribute to a higher flexibility, performance and punctuality of trains operating on single or dedicated lines and in heterogeneous networks. IAROR contributes to the development of new international standards for railway capacity and traffic management by integration of the state-of-the-art from different scientific disciplines as engineering, mathematics, physics, economics and computer science. IAROR aims at becoming the Network of Excellence in the field of railway operations research and an acknowledged advisor to governments, railway infrastructure managers, train operating companies and the industrial suppliers with regard to the development and evaluation of research programs, innovation strategies, directives and norms for railway operations.

IAROR organizes the International Conference on Railway Operations Modelling and Analysis (ICROMA) every two years since 2005. The previous eight conferences were held in Delft University of Technology, the Netherlands; Leibniz University Hannover, Germany;  ETH Zürich, Switzerland; University of Rome, Italy; Technical University of Denmark, Denmark; Chiba Institute of Technology, Japan; IFSTTAR, France; Linköping University, Sweden. The 9th international conference RailBeijing2021 will be held in Beijing Jiaotong University, China.

Scientific Topics 

RailBeijing2021 solicits contributions dealing with any aspect of railway operations modelling and analysis. Typical, but not exclusive, topics of interest are:

    Land use, mobility and line planning.

    Transport economic modelling for railways.

    Capacity and robustness in saturated networks.

    Impact of signaling and safety systems on capacity and punctuality.

    Impact of train priorities, dispatching rules and dedicated lines on network capacity.

    Optimal network timetabling and maintenance scheduling.

    Crew and vehicle scheduling.  

    Timetable stability, punctuality, temporal and spatial distributions of timetable margins.

    Scheduling and routing of passenger and freight trains.

    Real-time rescheduling, disturbance and disruption management.

    Prediction of route conflicts, arrival and departure times.

    Passenger flows in stations, on platform, and dwell time distribution.

    Multimodal transportation.

    Energy saving in railways.

    Impact of emerging technology on future railway operation.

    Governance, benchmark analysis and performance evaluation.

    Connections between railway and other transport modes.

    Due to the on-going worldwide crisis of COVID-19, we choose the hybrid conference model with physical local as well as remote online participation. The conference will be executed with an approved safety concept to ensure maximum safety for the participants in compliance with the applicable practice and regulations in China. With its hybrid model, RailBeijing aims at maximizing the quality of experience for all participants:

ü  The classic conference experience for those who can and want to travel;

ü  An interactive virtual experience for those who participate remotely.

    Details will be announced in due course.

Paper Submission and Important Dates

Prospective participants need first to specify the type of a submission:

    Type A: Research paper.

    Type B: Professional paper.

The authors of research papers (Type A) should submit a full paper of a maximum length of 20 pages in ICROMA format including figures and references, while the authors of professional papers (Type B) should submit a full professional paper of around 10 pages at the maximum.
