Road markings are crucial for traffic safety. Ireland's "Design Cycle Manual 2023" introduces new guidelines for cycle lane markings, enhancing road safety for cyclists.
However, designing these markings presents challenges. Ensuring visibility under all conditions and integrating seamlessly with existing road infrastructure is essential. Adapting these guidelines in urban areas, where space is limited, adds complexity.
Successful implementation requires careful planning and precise execution. The manual marks a significant step for cyclist safety in Ireland.

As we’ve navigated the Road Safety Roundabout, we’ve looked at the overall context of Australia’s road fatalities, how technology is impacting figures, and how design has reduced risks and improved safety. Faced with the impossibility of fixing every existing asset, we must look at the practical areas for focus and what emerging trends or technologies can help support improved road safety through design.
In our latest blog, Road Safety Roundabout – Safety in Design Part 2, we have once again collaborated with Kenn Beer of Safe System Solutions Pty Ltd. to look at the role of design in saving lives. Read more:

🚦Balance of Safety & Speed in Highway Design 🛣️
Highway design isn’t just about getting people from point A to point B faster—it’s about doing it safely. Designing for speed limits is one thing, but incorporating safety measures like proper signage, guardrails, and visibility enhancements is what truly makes a road reliable. 🚗
It's a constant balancing act: optimizing flow while reducing risks. The best highways are those that not only keep traffic moving smoothly but also keep everyone on the road safe, no matter the conditions. 🌧️

Innovative use of 'sight envelopes' on Offset Rural Channelised Left Turn Treatments.
Austroads Guide to Road Design Part 4A now includes a section on Offset Rural Channelised Left Turn Treatments. This was added as part of the 2023 update in response to many jurisdictions facing the dynamic visual obstruction issue of left turning vehicles masking the sight lines for vehicles at the hold line on side roads.

Roundabout, mini-roundabout, compact roundabout, traffic circle, rotunda, rotary… what’s the difference and why?
I was in Mackay, Queensland, this week running a Safe System Assessment course, and saw on Google Maps the ‘𝗪𝗼𝗿𝗹𝗱’𝘀 𝗦𝗺𝗮𝗹𝗹𝗲𝘀𝘁 𝗥𝗼𝘂𝗻𝗱𝗮𝗯𝗼𝘂𝘁’. Of course, this sparked my interest, so I jumped on an eScooter and made my way there with excitement.
While it was impressively small, I’m pretty sure it’s not the world’s smallest. I made a little video explaining a bit about roundabout design. But a few other questions people often ask:
1. What are the different names for circles at intersections?
2. Why would you design something small like this – why not just make it normal size?
Let me give some quick answers, and then I’ll welcome people adding to this in the comments.
𝗡𝗮𝗺𝗶𝗻𝗴 𝘁𝗵𝗲 𝗰𝗶𝗿𝗰𝗹𝗲𝘀 𝗮𝘁 𝗶𝗻𝘁𝗲𝗿𝘀𝗲𝗰𝘁𝗶𝗼𝗻𝘀:
This one is a bit jurisdictionally specific, but in Australia and New Zealand we would call anything with a diameter less than 4m a ‘mini-roundabout’. Anything that is in accordance with Austroads Guide to Road Design Part 4B would be a ‘roundabout’, and anything in between these sizes would be referred to as a ‘compact roundabout’.
The USA likes to use the term ‘traffic circle’ or ‘rotary’ for larger circles in the roadway with more of a traffic flow focus, and roundabouts for smaller circular infrastructure in the intersection with a safety focus. But it’s a bit different state-by-state. Here’s a fact sheet from Washington for those interested: https://lnkd.in/gkR4sRtU.
The only place in the world I’ve heard them using the term ‘rotunda’ for a large roundabout is in the Philippines.
𝗪𝗵𝘆 𝗱𝗲𝘀𝗶𝗴𝗻 𝗮 𝗺𝗶𝗻𝗶-𝗿𝗼𝘂𝗻𝗱𝗮𝗯𝗼𝘂𝘁?
As explained in the video, it’s about disrupting ultimate priority and keeping a smooth traffic flow. They work well in lower speed environments.
Some good 𝗾𝘂𝗲𝘀𝘁𝗶𝗼𝗻𝘀 𝘁𝗼 𝗮𝘀𝗸 𝘆𝗼𝘂𝗿𝘀𝗲𝗹𝗳 with mini-roundabouts:
❓ What’s your design vehicle?
❓ Are there appropriate facilities for pedestrians and cyclists?
❓ Is your pavement up to the task?
❓ What are the general operating speeds in the area, and do further speed calming measures need to be added?
Unfortunately, widening, building, or modifying a road takes longer than people think! It is a complex process. Each stakeholder has several complicated processes to ensure the project is run correctly.
The complexity comes into play when several entities have authority over an element of the project.
In this article, Mark Novitski lays out the various elements that have to work in order for roadwork to be undertaken.
There is sometimes years of planning before a single bit of ground is broken. Click to find out why roadwork can take so long from beginning to end.
