Chicago launches urban sensing project

The first phase of an urban sensing Array of Things project has begun in Chicago with the installation of the first of an eventual 500 nodes on city streets. The sensors will collect data on air quality, climate, traffic and other urban features, kicking off a partnership between the University of Chicago, 5041 Argonne National Laboratory and the City of Chicago to better understand, serve and improve cities.

Array of Things is designed as a ‘fitness tracker’ for the city, collecting new streams of data on Chicago’s environment, infrastructure, and activity. This hyper-local, open data can help researchers, city officials, and software developers study and address critical city challenges, such as preventing urban flooding, improving traffic safety and air quality, and assessing the nature and impact of climate change.

In the first phase of the project, 50 nodes will be installed in August and September on traffic light poles in The Loop, Pilsen, Logan Square and along Lake Michigan. These nodes will contain sensors for measuring air and surface temperature, barometric pressure, light, vibration, carbon monoxide, nitrogen dioxide, sulphur dioxide, ozone, and ambient sound intensity. Two cameras will collect data on vehicle and foot traffic, standing water, sky colour and cloud cover.

Initial node locations and data applications were determined based on interactions with community organisations and research groups. Some nodes will contain sensors for tracking air quality and its relationship with asthma and other diseases, while others will study pedestrian and vehicle flow and traffic safety or measure features related to urban weather and climate change.

Data collected by Array of Things nodes will be open, free and available to the public, researchers, and developers. After a brief period of testing and calibration, the project will publish data through the City of Chicago Data Portal, open data platform Plenar.io, and via application programming interfaces (APIs). As specified by the Array of Things privacy and governance policies, no personally identifiable information will be stored or released by sensor nodes.

    Optex will showcase two above ground ViiK vehicle detectors in Europe, Middle East and Africa at Intertraffic, in Amsterdam. The solutions are said to be ideal for sites where ground loops cannot be installed, such as where the road surface is damaged, unsealed, paved with cobblestones or above drains or pipes. The OVS-01GT is said to be designed for gate, barrier or industrial door activation and combines microwave with ultrasonic technology to sense a vehicle’s movement and presence. It is suited for

    Road authorities have a lot to gain from high-resolution traffic data, argues Pravin Varaiya. Traffic engineers have traditionally been forced to operate with limited data regarding the performance of their arterials. Traffic studies are often commissioned once every three years, over a few days, to get an updated estimate of utilization.

    While initial cost of radar based detection may be higher than that traditional loops, lower maintenance costs more than balance the books. Following successful field tests, the US city of Greenville, North Carolina, has recently agreed a new policy of phasing in Wavetronix traffic sensor technology’s radar-based SmartSensor Matrix system across its signalised traffic intersections. City traffic engineer Rik DiCesare expects the incremental implementation to deliver benefits to both the city’s taxpayers an

    Lucid Vision Labs has launched four Triton GigE vision cameras which it says can be used for ITS applications and traffic systems due to its IP67 protection rating. The cameras, which feature an interface for long cables up to 100m, come with M12 Ethernet and M8 I/O connectors to provide a robust connection resistant to shock and vibration - and an optional lens tube which protects against dirt, dust and water. Also, the range is expected to offer an operating temperature ranging from -20°C to 55°C ambi
