As traffic light posts are evenly distributed across cities, they pose a great opportunity to provide extra data coverage throughout the city. This includes both Wi-Fi and mobile data (4G). In Stockholm a City Wi-Fi will provide the means for leveraging the ‘Internet of Everything’ potential in terms of connectivity and real-time monitoring and enabling services to support and manage all aspects of city life and operations. The City Wi-Fi would enable connectivity and communication – IP based – over one common network infrastructure. This would enable Smarter City solutions in the areas of Traffic Management, Sustainable Mobility, Low Energy solutions for buildings, Video Surveillance and Incident Monitoring, Waste Management and Quality of Life.
This Smart Connected Street Environment is a process that involves the following steps:
In the Slakthus area of Stockholm, two types of sensors are installed to collect data on people and vehicle flow. The sensors are connected to the existing optical fibre network. When pedestrians and cyclists pass a sensor, a time and ID-tag is collected from their mobile phone device. When the same ID passes another sensor it is possible to, for instance, define the average speed and direction of the person. The other sensor is identifying vehicles' registration plates and checks it against the vehicle register. When there is a match, the vehicle information such as type of vehicle and level of CO2 emission can be defined.
This system gives very exact information of the transport emissions in the area over a given time. The real-time data in Stockholm is then transferred to IBM's IOT Watson environment, where it can be analysed, visualised, but also used for developing applications for users. Information from these sensors will in turn give indications for the need of other IOT equipment in the city environment. For instance, the City of Stockholm might want to communicate to car drivers, pedestrians or cyclists and therefore might use either apps or screens for this purpose.
A workshop with city departments and other interested parties was organised in March 2017 to define the types of analysis to be done.
