Spatial Distributions of Flow Density and Crossing Density and the Dependency on Routing System

都市内の移動経路と流動量密度・交差密度の空間分布

In this paper, the authors treat spatial distributions of flow density and crossing density in a unit square and circle with a uniform demand, and show their dependency on routing systems. First, the authors derive flow density and crossing density in a square with a rectangular grid transport system, comparing inner routing and outer routing systems, while both systems have same average travel length of internal journey. Outer routing brings about decentralized flow distribution and less amount of crossings. Second, the authors test flow density and crossing density in a circular city with a radial-arc transport system, comparing systems of radial routing, inner-ring routing, outer-ring routing, external-ring routing, and Kahlsruhe routing that gives minimum average travel length. The authors find out, for example, that Kahlsruhe routing brings about greater amount of crossings than inner- or outer-ring routing, but most of which concentrate at the center of the city.本研究では，一様な人口分布と稠密な格子状交通網および放射環状交通網を持つ都市において，典型的な経路に対する流動量密度分布および交差密度分布を求めることを目的としている．格子状交通網では，内回り経路と外回り経路の混合型を考え，外回りへの誘導することが移動距離の増加を伴わずに交差によるロスを減少させることができることを明らかにした．放射環状交通網では，放射・内部環状・外部環状・外周・Kahlsruheの５経路について比較し，放射・外周・Kahlsruhe経路は放射方向の負荷が大きくなること，内部環状・外部環状経路は環状方向の負荷が大きくなること，交差密度は，Kahlsruhe経路では中心部ほど高く，内部環状では中間部，外部環状ではさらにその外側において高くなること，交差総量は，Kahlsruhe経路では約24%となり，平均距離が最短であるが，逆に交差によるロスが内部環状などよりも大きくなることを明らかにした．
