A Conceptual Framework for an Integrated Information System to enhance Urban Mobility

Decision-making processes are essential in the design and operation of transportation systems. Multiple actors interact through these systems and their decisions may significantly influence each other actions, both at a strategic level and an operational and real time level. However, those decisions are often based on the same or similar data. Planners are interested in knowing congestion points to manage traffic, transport operators want to prevent delays, and travelers try to choose the best route for their trips. In this context, multimodal networks have a great potential to provide higher levels of service, and to improve system efficiency and city sustainability. Managing a multimodal network with multiple stakeholders can be achieved through integration and collaboration, and a smart incorporation of modes, along with well-designed interfaces and multi-platform information systems. In such a context, a diverse and dynamic demand from varied types of travelers (residents, visitors) and trip purposes (loading/unloading, services access) needs to be addressed. In cargo transport, vehicle dimensions, pollutant emissions or time/zone windows have also to be taken into account. To help decision-making processes in such multi-stakeholder contexts, we have created a conceptual framework for an integrated information system based on Enterprise Architecture Frameworks and Service Design approaches. Since this information system will be capable of integrating different data sources and provide different information for different stakeholders, the framework can hopefully be used in quite different contexts. In this work, we use it to address urban mobility issues.
