Instytut Transportu Samochodowego called “ITS” (Eng. Motor Transport Institute) began operating in 1952 under the Decree of the Minister of Road Transport and Aviation of 25 September 1951, on establishing the Motor Transport Institute.

The research problems dealt with by the Institute over the past more almost 70 years, have been undergoing constant changes. These changes were a result of the demand of the economy and the road transport as well as the technical and organizational progress.

Currently, the most important objectives of the Institute are:

  • Transport safety
  • Transport economics
  • Environmental Protection
  • Technical Safety

The Institute carries out a number of projects under EU programs, such as projects on electromobility, methanation or hydrogenization of the road transport.

The most fundamental tasks for the Institute’s operation are:

  • general improvement in functioning and organization of the road transport,
  • limiting harmful effects of the road transport and traffic development with regards the road safety and environmental protection,
  • developing new material solutions for the automotive industry, including improvement of the service materials such as oils, coolants, etc.

The Environmental Protection Center is a laboratory that carries out:
