Railway and Public Transport

Pendeltåg och buss i kollektivtrafik

We develop computational support tools for good planning of railway traffic and public transport. The tools can be used for evaluating systems and making better decisions. 

A good transport system is essential to allow access to workplaces, schools, service establishments and health care institutions and necessary for transportation of goods. Railway and public transport are energy efficient, environmentally friendly, fast, safe and secure. There is a strong will from society to extend and develop these systems.

The research group for railway and public transport is interested in developing models and methods, which describe the traffic and can be used as decision support tools by infrastructure managers and operators.

On a strategic level, we are interested in evaluating the imposed effects of changes in the infrastructure. At a tactical level we study timetables and schedules, and on an operational level how the planning can be adjusted just before or during operation.

Most of the methodological approaches come from the academic field of operations research, where we use optimization, simulation and statistics. An objective is often formulated as to gain time, cost, capacity, energy, stability or robustness.

Our research is often carried out together with stakeholders and funders from industry and society. The research group for railway and public transport is partner of the national research program Capacity in the Railway Traffic System (KAJT) and a national initiative for railway expertise, where we lead area 7 Traffic planning and control, and participate in area 9 Capacity and punctuality. Some of our collaborators are RISE - Research Institutes of Sweden, Swedish National Road and Transport Research Institute (VTI) and Swedish Transport Administration. The group consists of some ten researchers, half of which are doctoral students in the scientific area of infra informatics.

Reducing construction transport movements in cities

Construction transport in cities creates major disruption. This can be greatly reduced. But it requires better planning and management at an early stage in construction projects.

Can the cellular network be used to analyse travel patterns?

We are facing the challenge of meeting the climate goals while simultaneously accommodate human mobility demand. Nils Breyer has studied how the traffic system could be streamlined by using large-scale data sources for analysis.
