The growth of the use of wireless and internet technologies in transport systems, enables the provision of new information services based on vehicle-to-ground communications. There are many broadband management systems but most of them come from non-mobile environments. This results in a poor performance when deployed to environments where senders and receivers are moving. Such problems appear because transportation systems environments present specific requirements related to coverage, bandwidth and also a mix of communications networks. In order to tackle these challenges this paper presents the work in progress of a vehicle-to-ground communication middleware that aims to manage communication requests using a dynamic schema. The core of this new communications manager is an adaptive algorithm that selects the most favorable network link taking into account several actual and past aspects of the communications requests..
