# Looped Local Roads (49)

> Source pattern from the abridged `apl-md` corpus. Use as a design reference and constraint seed; do not treat as commercial-clean training data.

### Problem
>Nobody wants fast through-traffic going by their homes.

### Solution
>Lay out local roads so that they form loops. A loop is defined as any stretch of road which makes it impossible for cars that don’t have destinations on it to use as a shortcut. Do not allow any one loop to serve more than 50 cars, and keep the road really narrow—17 to 20 feet is quite enough.

### Related Patterns
... assume that neighborhoods, house clusters, work communities, and major roads are more or less defined -- [[Local Transport Areas (11)]], [[Identifiable Neighborhood (14)]], [[Parallel Roads (23)]], [[House Cluster (37)]], [[Work Community (41)]]. Now, for, the layout of the local roads.

Make all the junctions between the local roads three-way T junctions, never four-way intersections -- [[T Junctions (50)]]; wherever there is any possibility of life from buildings be oriented towards the road, give the road a very rough surface of grass and gravel, with paving stones for wheels of cars -- [[Green Streets (51)]]; keep parking off the road in driveways -- [[Small Parking Lots (103)]] and [[Car Connection (113)]]; except where the roads are very quiet, run pedestrian paths at right angles to them, not along them, and make buildings open off these paths, not off the roads -- [[Network of Paths and Cars (52)]] ...
