• Unified change tariff system enabling to make a ride by using a single ticket with the necessary changes, and this regardless of the selected way of transport and transporter
• Creation of conditions for market and competitive environment on the transport market with the objective to keep the necessary economic effectiveness of the operation, and this while maintaining the transport coordination and cooperation
