Transport planning for our future

The current challenge we face with traffic is that travel demand is higher than the supply of roads. Michiel Bliemer, Professor and Chair in Transport Network, is a leading expert in transport planning and traffic management who is developing new ways to forecast traffic volumes and conditions.

The modelling currently being used around the world by governments for transport planning dates back to the 1950s. Using these outdated mathematical models to predict how a road will benefit travel time, does not take into account congestion on our roads and assumes they have unlimited capacity. This can lead to ineffective use of the tax payer money, because roads that are not benefitting travel times are being funded.

Professor Bliemer has developed new models that are able to more accurately predict the impact a new road will have on cues, flows and travel times. As an example, the average travel time for someone in Sydney is worth around $20 per hour, these new models can more accurately predict how this cost would change if a new road was built.

The outcome from the new modelling will be more effective transport planning and better use of public funds. Everybody needs to be mobile, so being able to accurately predict our transport needs for the future is essential.
