Summary

Street design has an impact on population health. Yarra’s streets can be better for the health of residents and visitors if more budget and street space is allocated to walking and cycling.

Experts call for more space

Health experts call for more space to be allocated to walking and cycling.

Today, over 100 health and transport experts call on government to support safe walking and cycling.

Creating urban spaces for healthier lives

GTA Consultants point out that streets are being seen as places where life happens, and where communities are built; and it is timely to recast local streets as places to be rather than simply pass through.

Anything we can do to encourage more activity through good design and planning will have a material impact on decreasing the public health costs associated with managing these outcomes.

Health impacts in Australia

In 2005, the Australian Bureau of Transport and Regional Economics assessed the health impacts of transport emissions.

This study estimates that in 2000 motor vehicle-related ambient air pollution accounted for between 900 and 4500 morbidity cases — cardio-vascular and respiratory diseases and bronchitis — and between 900 and 2000 early deaths. The economic cost of morbidity ranges from $0.4 billion to $1.2 billion, while the economic cost of mortality ranges from $1.1 billion to $2.6 billion.

Pollution from exhaust and brake dust

In 2020, health impacts continue to be identified.

The harmful impact of air pollution caused by diesel exhaust fumes on our health is well known. It’s responsible for causing everything from respiratory problems to dementia and even certain types of cancers. But what most people don’t realise is that exhaust fumes aren’t the only cause of air pollution. In fact, up to 55% of roadside traffic pollution is made of non-exhaust particles, with around 20% of that pollution coming from brake dust. And as our latest research reveals, these particles may be just as damaging to our lungs as exhaust fumes.

What Yarra can do

Yarra can directly impact health outcomes by influencing transport policies, and the allocation of public space.

The below figure shows how health outcomes are shaped by policies, plans and programs as well as the profound effects they have on people’s behaviours and the environment they live in.

Health and longevity from low-intensity physical activity

The simplest and lowest cost method of improving population health is to enable people to integrate walking and cycling into their daily lives, such as going to work or the shops; and thereby decrease the number of vehicle kilometres travelled in our city.

Longevity all-stars don’t run marathons or compete in triathlons; they don’t transform themselves into weekend warriors on Saturday morning. Instead, they engage in regular, low-intensity physical activity, often as a part of a daily work routine. Rather than exercising for the sake of exercising, try to make changes to your lifestyle. Ride a bicycle instead of driving. Walk to the store instead of driving. . .

Blueprint for an active Australia

The Heart Foundation supports safe and active transport as a means of improving population health.

Specifically, they recommend investment in good movement networks.

Even better, the value for taxpayers extends beyond public health.

Conclusion

Yarra’s streets can be better for the health of residents and visitors if more space and budget is allocated to walking and cycling.
