The two yellow streets are main traffic corridors with 3 lanes of traffic in each direction. The street at the top is two lanes in each direction, the street at the bottom is one lane in each direction. There are eleven entrances into the tract (marked by red dots). There is a large condo complex and a shopping center bordering the tract on the left side.
To make it easy, I make a green circle in the center that indicates the preferred area to live in this tract. The streets toward the bottom of the tract might also be acceptable, but there is high density housing across the street. Generally, the outer streets of any tract will be less desirable because they are impacted by traffic and noise from outside the tract. The homes backing up to the condos and shopping center don’t have traffic, just multi-story buildings near their backyards.
Because traffic backs up on the various streets outside the tract, people attempt to beat traffic by cutting through the tract. Any streets that provide an opportunity for people to “cut through” should be avoided.
The green outlined area doesn’t include streets that provide direct entry into the tract, it is far enough from high traffic streets to where noise isn’t an issue and although it is possible to get from one side of the tract to the other using those streets, it isn’t effective to do so.
In short, the location minimizes undesirable impacts.
