Transport contributes to 24% of total greenhouse gas emissions in the European Union, leading to urban issues such as traffic congestion, car exhaust pollution, and energy shortages. Mobility as a Service (MaaS) and ridesharing are viewed as essential complements to other transportation modes, particularly in addressing energy and climate challenges. With the imperative of achieving climate neutrality by 2040, there is a growing interest in MaaS and ridesharing to reduce emissions. Ridesharing plays a significant role in the transition to sustainable mobility. The use of information channels is a good way of making ridesharing services attractive to users and offering the best possible services. While acceptance of shared rides is gradually increasing, changing behavior remains a challenge. In the MUST (Multimodal Traffic Management by Merging Innovative Communication Channels) project, we aim to optimize communication channels for impactful information delivery. Additionally, the goal is to enhance the routine commute, characterized by local knowledge and fixed or changing travel times. The main objectives of the MUST project are to directly and indirectly influence mobility behavior in terms of climate and environmentally friendly traffic management through traffic avoidance, modal shift and traffic improvement. One of our aims is to test which combinations of information can be used to convey transport information across target groups in order to achieve positive effects.
