Council harnesses IoT to cut traffic congestion


Sensors utilising Bluetooth and Wi-Fi-enabled technology are helping Portsmouth Council to monitor road conditions and keep the city moving.

The solution, which has been in place since 2013, monitors journey times and traffic patterns and measures the impact of road works and events. This real-time data is then used to reroute traffic to less congested routes and improve planning in what is one of the UK’s most densely populated cities.

The sensors, supplied by Danish internet of things specialist BLIP Systems and installed by local service provider Smart CCTV, have so far been used for key routes in and around the city.


Scalable solution

The mobile solution is easily scalable however through the addition of additional sensors and is being expanded to cover additional roads and to collect data on average speeds, log individual journeys and reveal ‘rat runs’. BLIP says the council can also identify parking issues in and around the city.

Commenting on the solution, Portsmouth City Council traffic engineer Lee Gilbert said: “The ease of extracting traffic data from the BLIP Systems dashboard is significant to see how time savings are achieved. Selecting the required route, date, time, etc. is very straightforward and simple to understand.

“Cost savings are being made by triangulating three or more data units, allowing multiple routes to be monitored.

“The majority of the Portsmouth residents are unaware of how a system like this benefits them to date which is unfortunate, but the reality is that close monitoring of travel times allow engineers to review routes where slower than expected journey times are being achieved with improvements to be investigated.”
