本文研究了一个二维随机格模型上的交通流，该模型包括两条旅行路线的交汇处：国内路线和国际路线，每条路线都有停车场。在我们的模型中，系统将到达的粒子分配到两条路线中的任意一条，并为每个粒子在路线中选择一个停车点，每个粒子在其行驶过程中在停车点停留一次。由于每个粒子在前后方向都有天线来探测其他接近的粒子，因此每个粒子的体积排斥效应在运动方向上延伸。系统表现出有趣的行为；值得注意的是，在达到国内航线最大停车容量后，吞吐量对国内航线颗粒分布比的依赖性降低。我们用排队模型对这一现象进行了模拟和分析，并得出如下结论：随着颗粒在国际航线上的分布比例降低，国际航线的吞吐量降低，同时国内航线的吞吐量趋于饱和。减少和饱和的同时影响导致整个系统的吞吐量减少。
This paper examines the traffic flows on a two-dimensional stochastic lattice model that comprises a junction of two traveling routes: the domestic route and the international route each of which has parking sites. In our model, the system distributes the arrived particles to either of the two routes and selects one of the parking sites in the route for each particle, which stops at the parking site once during its travel. Because each particle has antennas in the back and front directions to detect other approaching particles, the effect of the volume exclusion of each particle extends in the moving direction. The system displays interesting behavior; remarkably, the dependence of the throughput on the distribution ratio of particles to the domestic route reduces after reaching the maximum parking capacity of the domestic route. Our simulations and analysis with the queueing model describe this phenomenon and suggest the following fact: as the distribution ratio of particles to the international route decreases, the throughput of the international route reduces, and simultaneously, that of the domestic route saturates. The simultaneous effect of the decrease and saturation causes a reduction in the throughput of the entire system.
