- Creating more sustainable cities where there are economical and environmentally friendly ways to get around instead of just relying on private motorized vehicles
- Create systems with richer public realms so as to favor the creation of communities through regular social interactions
- Make cities where it's just plain better to live because of a vibrant culture and a lot of activities, economical and cultural
|A 20 000-people suburb with three supermarkets, 5-minute walksheds drawn around each one|
|A 20 000-people small city with 3 supermarkets|
|A dense urban neighborhood of 20 000 people with 3 supermarkets|
An example of how density increases active transport modes and transit, and reduces dependency on the car
|Example of an O-D sector and its info|
- Québec's metropolis, 1,6 million people in the city itself, around twice that including suburbs
- Has 4 subway lines that are very used and very frequent, and a complete bus system with many frequent lines in the city itself, which they call the "10 minutes max" lines.
- Commuter rail lines in the suburbs, but that only operate in the peak periods for the most part, and with pretty low frequencies
- Québec's national capital, around 500 000 people in the city, which has swallowed many suburbs over the years, 700 000 people including the suburbs that have not been merged.
- No subway, no tramway, no rapid transit. Just a few lines of "metrobus" which are essentially frequent bus lines with stops spread a bit further apart.
- A LOT of highways, very car-dependent suburbs, but a well-preserved dense inner city with European-inspired areas
|Transit mode share (y-axis) vs residential density (x-axis, people per square kilometer)|
- The absence of subway or other rapid transit line with high frequencies, which makes transit slow and much less useful. The subway seems to help the transit share even in relatively low densities, as sectors in Montréal with around 6 000 people per square kilometer (15 000 per square mile) have transit use about 50% higher than similarly dense areas in Québec City. Which shows the limited use of buses in mixed traffic to drive up transit use.
- Montréal is a bigger city, so even in the dense core there may be times where people need to take transit to go a bit further, whereas all the attractions in the urban core of Québec City may be closer together and thus be closer to dense areas, not needing transit to get there.

|Auto mode share (y-axis) vs residential density (x-axis, people per square kilometer)|
- If sectors have a lot of mixed use rather than use separation which increases distances
- If the area has highways cutting it in half and allowing fast car movements
- If sectors have good or bad transit service (in the case of Montréal, do they have access to the subway or not)
- If they have street grids that favor walking or street grids which makes walking more difficult
- If the population in the area is richer or poorer
