The project closing meeting of the "Infrastructure Capacity Analysis Research Project for Increasing the Effectiveness of the National Railway Network", which was started on 01.06.2021 with the General Directorate of State Railways of the Republic of Turkey, was held on Monday, 28.11.2022 at the Fenerbahçe Facilities of TCDD General Directorate.
The meeting was attended by Mr. Hasan PEZÜK, General Manager and Chairman of the Board of Directors of TCDD, Mr. İsmail DOĞAN, Director of TUBITAK TÜSSİDE Institute, as well as Regional Directors, Heads of the relevant Departments and Directors of TCDD Technical Engineering and Consultancy Inc.
At the closing meeting, Yakup AS, Project Coordinator, made an informative presentation on the sharing of the results obtained as a result of the work carried out within the scope of the project and the contribution made.
Summarize with the project;
- The impact of modernization projects on capacity has been updated with current load data and field studies, and their specific and general impact has been revealed.
- A capacity-focused prioritization model has been developed that can be used to evaluate projects.
- A conceptual model was developed to calculate the capacity of stations for passenger and freight transportation and a sample application was made for 5 stations.
- Maintenance Capacity allocation analysis and capacity utilization efficiency were analyzed and a relationship model was developed.
- A dynamic ORER planning model has been developed, aiming to minimize waiting times.
- A GIS-based decision support system has been created for current and future situations in detail based on capacity parameters.
- Capacity parameters were digitized, visualized and analyzed by means of GIS tools, taking into account the planned HSR, HT and Modernization projects.
- Current bottlenecks and possible bottleneck points for the years 2025-2030-2035 are presented according to alternative scenarios.
- Suggestions for improvement for potential bottlenecks for the future were put forward and a prioritization model was developed to assess the contribution of the suggestions.
- As a result of the analytical models, a capacity development 2025-2030-2035 road map supported by expert opinion has been created for the solution of possible bottlenecks.
- HSR-HT calculation models have been developed for the existing HSR-HT tracks and the tracks planned to be opened in the future, which calculate the maximum number of trips that can be made and the number of sets that will be needed.
