A simple change could make a huge difference for cyclists' safety and encourage more people to choose bikes over cars. But is it a realistic solution?
Slowing down cars to protect cyclists?
Recent research reveals that reducing speed limits from 50km/h to 30km/h in residential areas could significantly enhance cyclist safety without impacting car travel times. This finding is particularly relevant as Victoria introduces a new speed limit law, empowering councils to propose 30km/h limits in school zones and local streets.
The study, conducted by RMIT University researchers, analyzed traffic stress levels on Melbourne's roads. By modeling the impact of lower speed limits, they discovered that a 30km/h limit doubled the amount of bike travel on low-stress streets, creating a safer environment for vulnerable cyclists, including children and less experienced riders.
But here's where it gets controversial: Are slower speed limits enough?
Dr. Afshin Jafari, the lead researcher, emphasizes that slower traffic encourages more people to cycle, but Dr. Elliot Fishman, an expert in transport, argues that it's not just about speed limits. He believes that design changes, such as modal filters, are crucial to discourage 'rat-running' and create safer cycling environments. This perspective adds a layer of complexity to the discussion.
The research also highlights a concerning trend: cycling rates in Australia have remained low, despite government efforts. In cities like Sydney and Melbourne, many short trips are still made by car, even though cycling would be a more sustainable and healthier option. The main deterrent? Safety concerns.
A life-saving measure?
Dr. Fishman points out the stark difference in survival rates when hit by a car at 50km/h versus 30km/h. This simple change could save lives, as evidenced by countries like the Netherlands, where 28% of trips are made by bike, thanks to their adoption of 30km/h limits on residential streets.
As Australia aims to reduce emissions from the transport sector, increasing active travel like cycling becomes a priority. But is a speed limit reduction enough to achieve this goal? Or should it be combined with other measures to create a comprehensive solution? The debate is open, and your thoughts are welcome!
