residential_developer step target_units

[tianxie1995]

In the residential_developer step, current target_units is calculated by

semcog_urbansim/models.py

Line 1324 in 53212be

target_units = int(max((num_agents / (1 - target_vacancy) - num_units), 0))

and not taking the under-developing mcd_total_forecast table into account. So after the residential model step, it may still be possible for some MCDs to have insufficient HU supply for the HH target. Are we expecting this to happen?

When that happens, can we decrement the target_vacancy by increments of 0.01, until there is enough HU supply?

That's a good idea. But I think instead of decreasing, for MCDs which need more HU supply, the target vacancy should be increased so num_agents / (1 - target_vacancy) is larger.

Isn’t num_agents households? So you are releasing HU based on vacancy as opposed to placing HH.

How about we use target HHs from MCD forecast to replace num_agents?
