Aranda CBR Cycle Route C5: falling short of expectations

The ongoing saga of Aranda bike path and the lastest email from Tara Cheyne on the topic. Maintenance is sorely needed but despite the newest promises nothing has been done. ACT Labor has never got on top of this issue in their 19 years in government.

Aranda update 13 February 2021

The lower section of the Aranda bike path (C5) has been resurfaced following the 2020 ACT Election but is already cracking due to tree roots. The root cause of the cracking previously was also the trees. This problem is well understood as asphalt reshapes itself to the underlying ground like a glacier. Asphalt is more like plasticine than concrete. The ACT Active Travel Stand Drawings and Austroads recommendations for bike paths provide recommendations for bike path construction to avoid such issues. For roads the asphalt is laid on a thick compacted road base (for John Gorton Drive it has about a 30 cm thickness). The construction of a bike path is similar with a thick “road base” and a relative thin layer of asphalt over that. The “road base” is important as it provides the stability and load bearing that asphalt lacks.

Cycling in the ACT

The National Cycling Participation Survey (NCPS) is unusual for Australia. It is a standardised survey that has been repeated every two years since 2011. Repeating the survey regularly is the only way to find trends. The survey provides data on cycling participation across Australia and estimates of participation in the ACT too.

Coppins Crossing is missing bike lanes and more

Coppins Crossing Road is an example of a popular Canberra road without bike lanes. As today is our unofficial bike lane day, it is worth a closer look. On-road cycle lanes in the ACT are also discussed here.

The Coppins Crossing is a river level crossing on the Molonglo River built to rural road standards and only suitable for low volumes of traffic. As a north-south corridor and part of the Molonglo development, the traffic volumes along Coppins Crossing Road are high.

It will be replaced with a bridge in 2024.

The most recent update on the John Gorton Drive Bridge is found here from 12 February 2021.

Tactical urbanism: an agile approach to better cities

We all want better cities but it seems to take decades for any change. Tactical urbanism is an urban planning approach for delivering projects when needed. This webinar from Austroads tells us why we need it in the ACT.

Cycling fatalities with motor vehicles

Gravel riding, mountain bike riding, and cycling on separated bike paths – far from a road – are relatively safe. Injuries are possible but fatalities unlikely. Cyclists have much greater risks riding on roads. Collisions with a motor vehicle are more likely to be fatal. This is the story of what makes motor vehicles so deadly.

Safety is all in the mind

The perception of personal safety is very important for a cyclist. Many people will say that they do not cycle because they feel unsafe. Often authorities fall back to statistics, suggesting that it is not as bad as people think. However, if we want people to cycle they must first feel safe. A study in Berlin looks at cycle infrastructure that makes people feel safe.
