Research institutes subordinate to the Minister of Infrastructure in the field of transport: the Road and Bridge Research Institute, the Railway Institute and the Motor Transport Institute have concluded an agreement on establishing the Polish Transport Research Institutes Network (POLTRIN).

The idea behind the agreement is to strengthen the potential of research institutes, enabling the implementation of large research projects for the development of transport, economy and competitiveness of enterprises.

Three institutes conduct complementary activities and have been cooperating for many years both in the field of research projects and, for example, in the area of certification. They are linked by many short-term and long-term contracts. Establishing a network bringing together research institutions will help to systematize these activities and facilitate joint initiatives. Projects related to large transport projects throughout the country, such as the construction of new roads and highways and the modernization of railway lines, will be of particular importance.
