Our principal goal is to provide the Latvian national economy with qualified human resources for its stable growth and development. We work with our students sharing our knowledge, skills and experience as well as try to communicate to them also the spirit of zealous search for the new – the spirit of investigation, the desire to stretch their minds, invent and innovate. RTU is the only many-branched technical university in Latvia. Now there are more than 17 000 students, including 400 Doctoral degree students, 3200 Master’s degree students, 10000 Bachelor’s degree students, 1400 Academic personnel.
RTU Research Capacity: 30 Laboratories, 33 Institutes, 103 Departments and Divisions, 435 Researchers
RTU has expertise in application of formal methods for safety and performance evaluation, development of software and functional prototypes for onboard electronics and embedded control and safety systems for railway transport domain.
Research fields: intelligent transport systems, evolutionary algorithms for embedded systems, genetic programming for embedded systems, energy saving multifunctional power electronic converters, performance optimization services for electric drives, diagnostics of group traction drives and vibration of locomotives, standard development in railway transport.
RTU is involved in the desing and development of specialized projects for transport systems and its’ optimal control, i.e. maximization of energy efficiency, capacity and safety and minimization of exploitation costs using high technologies.
