The CitiCAP Project aimed to change the attitude and behaviour of citizens towards mobility to promote the shift from private car use to sustainable mobility. The lack of mass-transit options in Lahti, and in many other medium-size European cities, emphasised the need to create smart mobility solutions to reduce traffic CO2 emissions. Approximately 32% of total CO2 emissions is contributed by the traffic sector within the city area of Lahti.

Today roughly 250 European cities have fostered their mobility planning using the Sustainable Urban Mobility Plan (SUMP) process. However, the participation of citizens to integrated mobility planning and new radical SUMP incentives required the revision of the SUMP process. CitiCAP seeked to develop new transport services for citizens while creating innovative incentives for sustainable mobility.

The project also focused on integrating the ITS approach into the sustainable urban mobility planning. Cities produce large amounts of mobility and traffic data, which society cannot fully utilise because this data is very segregated and is normally not made available to the public. Different traffic data produced in Lahti accumulate to differential storages and data providers.
