Dr Alex Macmillan, a physician and environmental health lecturer at Auckland University, propagates on building bike lanes instead of an inner city rail loop.

She propagates on the theory that biking and cycling would reduce inequalities as it is a healthy way of transportation and it is most economical way of travel. Currently 10 % of poor family’s income is spent on transportation fares and petrol. This will help those families in saving that money and provide them with better and healthy life.

She said that bike lanes could be created in every arterial road and traffic calming could be installed in every street for approximately $ 1 billion which is half of the budget of $ 2 billion cost of a downtown rail loop.

"Half the cost of the CBD rail loop could buy you a universal transformation of Auckland streets that would give you a bicycle mode share competing with the most bike-friendly cities in the world", said Macmillan.

The bike lanes could be created adjacent to footpath by shifting bicycle lanes from outside the car parking to behind the parking. The benefits of the cost saving will be immaculate as 10:1 when compared with the cost of city rail loop.
