Summaries of content, keywords and links generated by algorithms. Thank you smmry.com:
Summary 1: A loop is defined as any stretch of road which makes it impossible for cars that don't have destinations on it to use it as a shortcut.
Summary 2: 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.
Summary 3: " We define a looped road as any road in a road network so placed that no path along other roads in the road network can be shortened by travel along the "loop.
Summary 4: The loops themselves must be designed to discourage high volumes or high speeds: this depends on the total number of houses served by the loop, the road surface, the road width, and the number of curves and corners.
Summary 5: A way of closing streets to form looped local roads.
Summary 6: Make all the junctions between local roads three-way T junctions, never four-way intersections - T JUNCTIONS; wherever there is any possibility of life from buildings being oriented toward the road, give the road a very rough surface of grass and gravel, with paving stones for wheels of cars - GREEN STREETS; keep parking off the road in driveways - SMALL PARKING LOTS and CAR CONNECTION; 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.....
