Translating traffic safety data into valuable insights

Making complex data approachable

— Translating traffic safety data into valuable insights

 

We now live in a world of data.  But raw data isn’t valuable in and of itself, rather the value is created when it is collected accurately, connected to other relevant data in a timely manner and translated into information.

 

At Real Time Traffic, we use many different sensors to collect a lot of traffic safety data.  The data is complex and very granular.  For instance, in a recent project, we captured the trajectories of motorbikes through a curve in a high-speed zone with our computer vision capability.

 

How exactly can we explain such technical data in a simple and approachable way?  How do we help our traffic safety experts understand what is going on?  And can we help their time-poor bosses get the same insights without needing to delve into the deep bowels of the data world?

 

Make complex data into something simple

With our motorbike trajectories project as an example, we share some of the things we do to make highly complex traffic safety data into valuable insights that even our non-data savvy friends would understand.

 

Motorbike Safety Analysis

 

Firstly, our computer vision algorithms do the hard work of extracting the timestamps and position of each motorbike through the curve.   For this study, our traffic safety experts are particularly interested in how far the motorbike is from the centreline.  To produce this insight, we created a heatmap.

Provide context with the data in one visual hit

The data captured has a geospatial context.  To provide that context, the heatmap is superimposed over a map.  Using a satellite view provides even more context.   Sourcing high resolution up-to-date satellite images can be prohibitive.  In our projects, we use our imagery captured from our drone instead to provide the most up-to-date and accurate view.

An interactive version always helps

And finally providing an interactive version where our users can zoom in and out helps them.  In this example, we placed an interactive heatmap and trajectories through the curve side-by-side to help our traffic safety expert understand motorcyclists behaviour.
