The Dresdner Verkehrsbetriebe AG (DVB) has had a modular ITCS in place for several decades, with its components supplied by various manufacturers. With this partial project, it aims to modernize several components within the ITCS in order to meet future demands in traffic management through new, powerful communication technologies within the vehicles and via the air interfaces to the control center as well as the vehicle environment.
As part of the equipment and implementation, all buses and low-floor trams of the DVB are to be equipped with an appropriate onboard computer. In addition, the audio management system of the DVB control center will be replaced, and the radio communication for voice and data communication between vehicles, dispatchers, and the land side will be modernized.
The scope of tasks for this assignment ranges from the development of entirely new functionalities based on new hardware and software to the preservation of proven existing functionalities and interfaces to connected systems and components that will be maintained during the processing. After the services are implemented, service tasks, such as maintenance, must be provided over a period of 10 years.
The DVB explicitly points out that the overall project is being implemented with the use of funding from the EFRE (European Fund for Regional Development 2021-2027). The financing of the part project advertised here is taken into account in the client's economic planning with the corresponding dependency on the funding. The client expects the final funding approval in Q3 or Q4/2025. The DVB further emphasizes that it is a KRITIS operator in the transport and traffic sector in accordance with the BSI Kritis Ordinance.

Procurement of Onboard Computers and an Associated Radio and Audio Management System as Partial Services of the Overall Project MIKT (Modernization of Information and Communication Technologies).
1. Vehicle-side components and functions As part of the partial project, the onboard computers of 416 trams and buses used in regular service, as well as the onboard computers of 16 business, special, and historical vehicles, are to be replaced. In addition to the vehicle equipment, the supply of 15 vehicle-type-specific prototypes for testing in the DVB ITCS laboratories and by the control system manufacturer, as well as 26 devices as operational reserves, is required. Furthermore, the DVB reserves the right to equip an additional up to 50 vehicles due to fleet changes and to double the operational reserve with an additional 26 devices.
2. Modernization of the Radio System The radio system, which handles voice and data communication between the control center, public transport vehicles, and dispatchers, needs to undergo a fundamental modernization in this partial project. On the one hand, the radio system no longer meets the requirements of the increasing traffic networking with acceptable financial resources. On the other hand, the components of the TETRA radio system have been phased out. Against this background, the public mobile network (PLMN) should be made usable for both voice and data radio connections through this partial project and, if necessary, the operational radio network should be modernized. Two potential implementation variants have already been identified (see Chapter 3 of the assignment). Additionally, further variants can be developed during the dialogue phase. Ensuring compliance with legal requirements for the radio system used in tram operations according to BOStrab receives particular attention.
3. Modernization of the Audio Management System For voice communication in the control center, the goal is to establish a VoIP-based communication solution (audio management system) that integrates the voice services of radio, telephony, and voice recording into a single system, providing the control center dispatchers with a unified user interface. The user interface should be available as both hardware and software client.
4. Service Phase After the overall acceptance (expected by no later than 30.09.2028), the contractor must ensure the long-term operational capability and reliability of the entire system over a period of ten years through regular maintenance, timely repairs, and continuous system updates. A twice option to extend the service phase by two years each is provided.
