Find an area delineated by major roads. This will be the location of the superblock.

• Ideally, it should have mixed zoning and public transit links that connect other parts of the city
• A metro or train station is the best, but trams and buses can also do the job

Reorganize directions of traffic.

• Strategically placed one-way streets
• Possible to drive in and out of the area, but not through it, eliminating transit traffic is the key to superblock design
• Bicycles and street-level public transit should be an exemption from this, of course

And with that, most of the work is already done!

Limit parking for non-residents

• Pricing should disincentivize car ownership
• Pricing should take into count size and proportion 

Mixed traffic spaces

• If there are people around, drivers will be much more careful
• We now have space for bike lanes and restaurant terraces
• But most importantly: trees, which will keep the superblocks nice and cold during summer

Congratulations! You just made an entire district much more liveable. 

• Most of the air pollution is now gone
• Streets are safe now, and you don't have to be afraid of getting run over
• The streets are nice and cold during the summer and heatwaves
