Let's look at the research when road capacity is reduced...
The bridge has good capacity as most congestion is on the motorway approaches to the bridge, where lanes merge. But in NZTA/Waka Kotahi's reports into the impacts of taking a lane, they say it's not feasible because cars and trucks would be left with 'only seven lanes' and they assume no-one gets out of their cars to walk, scooter or cycle..
Reallocating a lane to support mode shift, as advocated in NZTA's Keeping Cities Moving can lead to traffic evaporation.
Evidence of traffic evaporation:
This article 'disappearing traffic' reflects on the dynamics and flexibility of people’s travel choices and why traffic can disappear. Also how disruption to transport systems can force behaviour change for the better.
This article discusses what really happens when road space is reallocated.
Then there are the downstream benefits of evaporating traffic - people walk and cycle more, children play outside more, air pollution declines, and life expectancy improves.
Research shows reducing roads can cause traffic to evaporate says this article. People are adaptable, and change their behaviours in response to infrastructure - and its limitations to pursue the most efficient means of transport, so traffic can be induced - or alternatively 'disappear', accordingly.
And this article shows why, using Braess Paradox and Game theory - people adapt.
The 21st Century Paradigm supports walking and cycling to transport more people than lanes for cars. Solving climate change, sustainability, public health, social connectivity and movement all at once.
