An increasing amount of parties wants to join the data chain, more outdoor objects are digitally linked and more cities acknowledge the added value of being able to guide and manage groups of road users in a smart way. As a result, Talking Traffic is becoming increasingly important for governments as a combination of tools for simplifying management and maintenance, as well as policy decision-making. Interest in this type of data-driven mobility is growing, especially in cities that are in the process of rolling out the Smart City concept. They are increasingly aware of the possibilities offered by Talking Traffic applications: determining which vehicles are allowed to enter an environmental zone and which are not, granting a degree of privilege to shared cars or electric cars, or determining in a simple way that residents of an apartment complex, i.e. access traffic, have access to a certain road that remains closed to others. The availability of real-time data offers a view of what is happening on the streets in the city at any moment in time. That view enables authorities to steer and facilitate desired mobility behaviour, but also to manage other challenges in areas such as housing, climate change and energy transition in an integrated and targeted way. An increasing amount of cities in the Netherlands consider this form of data-driven mobility to be a major cornerstone for making cities smarter, more sustainable, cleaner and safer.
