Negotiations with MPK and ZTM in Lublin regarding the initial implementation of CLD and carrying out trial tests for optimizing the construction of brigades for the bus fleet have entered the final stage. A new algorithm created as part of previous EU projects and the currently implemented 514_ELEKTRO project will be used for testing. The tests will be conducted in summer months on real data from ZTM in Lublin. If the first test results bring good results, another contract will be signed in the fall for the full implementation of both systems (CLD and TransERP) in ZTM and MPK.
