If straight lines of infinite length are placed at random on the plane such that the relative numbers in a range of directions is described by a continuous function then it is proved that the maximum crossings per unit area for a fixed length of line per unit area occurs when the lines are provided equally in each direction. 相似文献

Two types of routeing on a rectangular system of roads are examined in a simple circular city where homes and workplaces are uniformly and independently distributed. Expressions for the number of vehicles crossing a given line segment, the average distance travelled by a commuter and the total number of crossings of vehicle paths in the city are derived. Comparisons are made with other routeing systems in terms of average distance travelled, expected number of crossings and average travel time. 相似文献
