Located on the northern bank of the Yarra River, Birrarung Marr, a place of spiritual and cultural importance to traditional owners, features a range of native flora and sculpted terraces and is a popular site for exercising, leisure and commuting through.

Currently, sensors are used in open spaces like Royal Park, Argyle Square and Southbank Promenade to better understand user behaviour and inform how our parks are designed and managed. In Birrarung Marr, we’ll continue to trial how we use emerging technology to drive great city experiences.

A variety of sensors will collect information in the park to help us understand behaviour over time, share data insights with the community and inform future planning of open spaces. Insights from data collected will be shared with the community.

The details

Sensors are a useful tool to help us understand our parks and other open spaces. For instance, they can tell us how usage changes over time, opportunities for improvement, the impact of developments and, importantly, help us to have conversations with the community.

Argyle Square in Carlton was the first Melbourne open space to be ‘sensed’. We’ve been collecting and storing data from Argyle Square since 2020. Royal Park was our second 'Data in the park' project, enabling us to trial new types of sensors and develop insights about park usage.

We have started implementing sensors in Birrarung Marr. Some of the sensors we’re using have been tested in other parts of the city such as the Bluetooth sensors that are part of our Pedestrian Counting System and micro-climate sensors in parks including Argyle Square and Royal Park. We’ll also be trialing new sensors in order to capture useful data.

Data collected will help provide insights into areas such as:

  • the busiest times and days
  • the key modes of transport and how their usage patterns differ
  • the micro-climates here and how user behaviour changes in different conditions
  • the seasonal trends for usage
  • the most popular places in the park and the duration people spend in the area.

We’re currently exploring how other sensors could provide useful data. We’ll update this page as we implement new sensors and share any useful data via a dashboard.

The technology

  • The Skyfii mobile phone counting pedestrian sensor counts the number of devices that emit a Bluetooth signal. We de-identify each Bluetooth signal and randomise it so it is not personally traceable.
  • The Ouster sensor uses Li-DAR technology. Li-DAR stands for Light Detection and Ranging and uses a laser to emit light. It measures the time for the light to reflect off an object and return to the sensor. Li-DAR is useful technology to get an accurate understanding of activity in specific areas.
  • The Micro-climate sensor captures a range of data including temperature, humidity, particulate matter in the air and more.
  • The Skyfii Bluetooth sensor sends data across telecommunications networks via a SIM card.
  • The Ouster Li-DAR sensor also sends data via a SIM card.
  • The Micro-climate sensor sends data via LoRaWAN, Low Range Wide Area Network. This network is used for devices that only need to send small amounts of data.

The data is used by City of Melbourne to design, plan and maintain Birrarung Marr and other green spaces in the city. The data will be shared with the community via a dashboard on this page soon. Stay tuned.

This data is stored permanently for records and analysis. We are not collecting any data that could personally identify anyone.
