1. Delays and Timetabling for Passenger Trains
Sammanfattning : Travel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. LÄS MER
2. Challenges with Driverless and Unattended Train Operations
Sammanfattning : Demand for transportation continues to increase, for both freight and passenger services. One of the most energy-efficient modes of transportation is rail. One solution to increase the attractiveness of rail transport is to introduce automatic train operation (ATO) with a high grade of automation (GoA). LÄS MER
3. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports
Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER
4. Application of Predictive Analytics for Shunting Yard Delays
Sammanfattning : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. LÄS MER
5. Applying Data Analytics to Freight Train Delays in Shunting Yards
Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.
