Intermodal Mobility Assistance for Megacities

IMA develops an open mobility platform where mobility-related providers are able to offer their services in a standardized fashion. The assistance system integrates these services with semantic annotations to provide users with personalized intermodal travel recommendations.

Motivation and Goals

The ever increasing urbanization has significantly aggravated the traffic situation in megacities. Common travel habits, such as using a vehicle, are challenged by factors like severe congestion, insufficient parking availabilities or present full prices. Furthermore, growing traffic entails an increased level of noise and greenhouse gases and thus affects residents even more. The IMA project aims to utilize means of transportation in a more effective and sustainable fashion in order to increase the quality of life in cities and to contribute to global environmental objectives. In IMA, this utilization is realized by a capable assistance system which proposes intermodal traveling options which are tailored to the users´ needs that are also constantly monitored.

Approach: Mobility platform and assistance

One objective of IMA is the development of an open mobility platform, where providers of mobility concepts or traffic-related information services are able to offer their services in a standardized fashion. The assistance system accesses these services and uses semantic annotations to calculate individual travel recommendations. These recommendations are communicated to users by means of multimodal interfaces. The assistance system continuously observes the trajectory of the user and traffic related data and is thus able to notify users in case of unexpected route deviations or sudden traffic disturbances. Impacts of infrastructural changes can be predicted by an additional simulation component. Another very important aspect in IMA is to ensure data security and privacy.
