Urban mobility computing is a process of acquisition, integration, and analysis of big and heterogeneous data generated by a diversity of sources in urban spaces, such as sensors, devices, vehicles, buildings, and human, to tackle the major issues that cities face [1,2]. In this respect, one of the major application areas of urban computing is to improve private and public transportation in a city and traffic congestion management stands on top of the most compelling challenges.
One of the most sustainable solutions is to start a feedback loop that induces more and more people to make a modal shift away from driving. Nevertheless, in the city of Tallinn making the public transport free did not increase its attractiveness. In this respect, making the public transport more convenient will increase patronage, which means that the service can be run more frequently and for longer hours, making it attractive to more people.
Key interventions to reduce traffic congestion include:
- Optimise traffic-light management: Traffic signals have been installed throughout road networks to control competing traffic flows at road intersections. These traffic lights divide time between conflicting flows and enhance vehicle safety while crossing road intersections by scheduling conflicting traffic flows. However, traffic signals may decrease vehicles’ efficiency in traffic networks.
- Car sharing and multi-modal solutions: Car sharing has huge potential to improve quality of life and traffic conditions in cities. It offers a car at your disposal without the need of ownership and has the potential to reduce the number of cars in cities without reducing individual mobility. The wide spread of information and communication devices (smartphones in particular) and of social media and web platforms, together with the sharing economy that is growing into a cultural consumption approach, are at the basis of this development. Moreover, smart technology has helped to improve the experience of using car sharing, making booking, accessing and using shared transport easier.
- Sustainable global schema of traffic light management
- Impact of this global schema on the reduction of unbalanced ratio of Public Transport and private transport through the determination of key bus stops.
- Quality of Driving assessment and its consequences on car rental/sharing.
- Car sharing and public transport in Tallinn towards a better multi-modal integration 
- Inception phase: Literature review, discover and comparison of related technologies, running tests for performance analysis.
- Contribution phase: Creating algorithms and implementation tools based on them.
