网络宏观交通流模型的间断Galerkin方法

Discontinuous Galerkin method for macroscopic traffic flow models on networks

Lukáš Vacek, Václav Kučera

摘要:

在本文中,我们描述了一种数值技术的解决方案的宏观交通流模型的道路网络。在个别道路上,我们认为标准的莱特希尔-惠瑟姆-理查兹模型,该模型是离散使用不连续伽辽金法以及适当的限制器。为了解决网络上的交通流,我们构造合适的数值通量在路口的驾驶员的偏好的基础上。我们证明了所构造的数值通量和所得到的方案的基本性质,并提出了数值实验,包括一个路口与复杂的交通灯模式与多个阶段。与Čanić等人的结处数值通量方法的差异,2015年,讨论并证明了一个简单的网络数字。

英文摘要:

In this paper, we describe a numerical technique for the solution of macroscopic traffic flow models on networks of roads. On individual roads, we consider the standard Lighthill-Whitham-Richards model which is discretized using the discontinuous Galerkin method along with suitable limiters. In order to solve traffic flows on networks, we construct suitable numerical fluxes at junctions based on preferences of the drivers. We prove basic properties of the constructed numerical flux and the resulting scheme and present numerical experiments, including a junction with complicated traffic light patterns with multiple phases. Differences with the approach to numerical fluxes at junctions from Čanić et al., 2015, are discussed and demonstrated numerically on a simple network.
