How the Hoddle Street Streamlining Project reduced peak hour congestion by up to 14%

With a $110m budget to upgrade four key intersections, how much has
traffic flow and congestion improved on Hoddle Street?

Using Intelematics traffic flow data, we conducted a before and after analysis for 2017
and 2019 to discover the recent roadworks have in fact reduced congestion and
improved traffic flow.

Intelematics capture data through hundreds of thousands of sensors Across Australia located on roads, in vehicles and infrastructure. The data we capture provides context around traffic trends, accident blackspots, the most congested areas, the most dangerous roads and more so getting to the bottom of just how congested Hoddle street was before the roadworks and now, is a simple task that only takes a few minutes”

Do you have a hypothesis about just how congested a particular stretch of road is, or need to prove that a recently finished traffic management project has in fact, improved congestion?

Your traffic flow questions can be answered in a matter of minutes with readily sourced and easy to decipher traffic flow data from Intelematics.

Take the recently completed Hoddle Street Streamlining project as an example. The project was designed to improve the travel experience for 330,000 people who travel along and across Hoddle Street every day. Works started in 2018 and were completed in 2019. Four major intersections were upgraded and it included the creation of Victoria’s first Continuous Flow Intersection at Punt Road and Swan Street.

Using Intelematics data – I had the answer in a matter of minute

For the purpose of this analysis I looked at one day in August 2017 and the same day in August 2019 but because the files are broken down by month, day, and time (15-minute increments), it can be sliced and diced however you see fit. You can look at it by month, day, time, travel times, actual speed, delay in seconds and more.

What I wanted to look at was actual speeds so I took the same day in August 2017 and 2019 from both files, put them side by side, and built a line chart in a matter of seconds and this is what I saw – from 6.30 AM to 7.30 PM the actual speed was faster in 2019 than it was in 2017. Outside of this main period the speeds were similar however, this was outside of the peak times when congestion doesn’t cause the same issues.

Performing the same analysis for your next project is easy

Hoddle Street is on the border of two suburbs Collingwood and Abbotsford so I could purchase a file for either suburb knowing the data would be in both. I knew this because Intelematics Traffic Flow calculator lists the exact roads available in every individual file before you make a purchase.

It was easy to purchase the file. I just selected the suburb and the years I wanted data for from the Intelematics Traffic Flow page, proceeded to the checkout, and purchased the files using my credit card. Because this is a before and after analysis, I purchased the 2017 and 2019 Collingwood Traffic Flow files.

The files were delivered to my email inbox too so the whole process was really fast and easy.
