摘要
在公共交通预测“四阶段规划模型”中,客流分布预测起着承上启下的作用,非常重要。应用最广泛的客流分布预测模型当属重力模型,从最基本的重力模型展开,分别描述了标准重力模型、单约束重力模型和双约束重力模型,并对各模型的标定和算法及应用进行了相应介绍。
In mass transit planning model, the passenger flow distribution forecast is extremely important. The most widespread model used in passenger flow distribution forecast is the gravitational model. This paper described the standard gravitational model, the single restraint gravitational model and the double restraint gravitational model respectively from the basic gravitational model. Finally, it presented the solution approaches, algorithms and application of these models.
