Professor Piotr Kisielewski took part in the sessions of an elite association, the Polish Association of Public Transport Employers held between June 4th and June 5th. We were invited and recommended for participation by the management boards of the largest Polish urban carriers. The meeting took place in Tatranská Lomnica in Slovakia and it was an opportunity to discuss current issues related to transportation in Poland, especially in the area of timetable design. It was also an opportunity for networking with the management board members of several carriers.
