In-vehicle application for multimodal route planning and analysis

People are constantly inventing new ways of reducing traffic in big cities and encouraging the use of public transport. The idea of park-and-ride facilities is to increase the usage of public transport. However, it imposes additional problems for a driver to plan her trip and does not state clear benefits of using the approach. We developed a seamless solution to guide a user to public transport transfer spots by combining Web services, vehicle data and integration with an in-car infotainment system. Our solution offers optimal parkand- ride transfer points, instantly shows the benefits of taking a transfer to means of public transport and guides the driver throughout the whole trip, in car and in the public transport. We tested the system in Helsinki Capital Area and developed a tool for analysing multi-modal transportation scenarios. By customising the system using various optimisation parameters such as CO₂ emissions or trip time, we show what savings can be achieved in different scenarios.
