Safe System Snippet 535: Angles and Speeds – Roundabouts are the Winner (for vehicle-to-vehicle crashes).
Why do crashes at roundabouts tend to be less severe than those at traditional intersections (crossroads, t-intersections, signalised intersections)? Two factors play a big role - speed and angle. Roundabouts naturally slow vehicles as they approach and move through...
Kenngineering Notes: Safe System heavyweight fight – Australia vs Aotearoa New Zealand
Closing keynote slots can be dangerous. The audience has already heard a lot and the energy is dropping. You need something to bring the oomph back. So at last week’s Transportation Conference in Aotearoa New Zealand, I threw in a Safe System heavyweight fight. --...
Kenngineering Notes: Another motorcyclist NOT hitting a wire rope safety barrier
Another motorcyclist NOT hitting a wire rope safety barrier.( that’s not the point of this post, but I thought I would get it out of the way before the comments come in ) What I'm very interested in is the joint sealant here that appears to have destabilised the...
Safe System Snippet 534: Dynamic Visual Obstruction
Be honest, were you ready for that blue car? Dynamic Visual Obstruction is when one vehicle blocks sightlines to another vehicle or road user. Left turn lanes (like the one below) create a situation where this becomes more prevalent. Make sure you think about these...

Kenngineering Notes: Transportation Conference 2026 (📍Wellington NZ)
The conference app chat made me laugh. Great to be back in Wellington, New Zealand for Transportation Conference 2026. But I could not help but giggle at the discussion happening in the conference app. Dr. Elliot Fishman asked the question many people had been...
Kenngineering Notes: Number of people killed by travel mode
Last week I was teaching the Road Safety Audit course and running the module on infrastructure design for motorcycle safety. I mentioned that, no matter how you look at it, motorcyclists are significantly over represented in road trauma (which is why Auditors need to...
Kenngineering Notes: When is a crossing ‘warrented’
I use this analogy a lot when pedestrian crossing 'warrants' come up. It usually gets a laugh first… then a pause. Anyways, sharing it here in case it helps you get people over the line to create safer and more accessible roads and streets. (Note: I didn’t come up...
Safe System Snippet 533: How we can learn from crashes
Last week our engineers were obsessing over the technical details of this crash in Tasmania involving a light pole and roadside barrier. (Thankfully, we understand no one was seriously injured.) From the footage, it appears the white ute has pocketed into the light...

Kenngineering Notes: POV Perceptions of Road Users
I posted this a couple of years ago and people still ask me for it, so here it is again. This was from when I first started experimenting with AI. I asked it to create a pictorial view of how different road users perceive each other. Interesting, isn’t it. ————-...
Kenngineering Notes: Comparing 100km/h Highways via AusRAP
Earlier this week I was chatting with one of our young gun engineers. By chatting, I mean he innocently asked a question and somehow found himself in an impromptu lecture on speed limits and speed management. Occupational hazard, I guess. One of the points I made was...

Kenngineering Notes: The Beer Zipper reunion
Finishing off the week in Washington, D.C. I had a brilliant catch-up with David Zipper. If you’re in DC and care about road safety and sensible transport, you make time to see this man. Apart from coining the term ‘Car Bloat’, authoring countless articles,...
Kenngineering Notes: Black Audio Tactile Line Markings
I’m in the passenger seat on the way home from Port Fairy, just marvelling at the black Audio Tactile Line Marking (ATLM) offset from the edgeline. Why is it done like that? Maintenance. If ATLM is placed on or right next to the edgeline, it gets struck frequently and...
