reduction is very high here. This reflects the modelling approach for the cycling package. There is no cycle (and walk)
model available in Auckland, hence future cycle movements were based on mode shift from a proportion of vehicle movements
under 10 km in length.
The modelling is based on individual model runs for each level of application of a policy package. MCA
indicator impacts are derived from travel distance, mode share and speed outputs.
