ABSTRACT

This paper introduces a new approach to hybrid traffic modelling, along with its implementation in software. The software allows modellers to assign traffic models to individual links in a network. Each model is a plugin that implements a series of methods, referred to as the modelling interface. These methods are used by the program to exchange information between adjacent models. Traffic controllers are implemented in a similar manner. The paper outlines the important components of the method: the network description, the description of demands, and the modelling and control interfaces. We include tests demonstrating the propagation of congestion between pairs of macroscopic, mesoscopic, and microscopic models. Open Traffic Models is an open-source implementation of these concepts, and is available at https://github.com/ggomes/otm-sim.

摘要

本文介绍了一种混合流量建模的新方法，以及它在软件中的实现。该软件允许建模者将流量模型分配给网络中的各个链路。每个模型都是一个实现一系列方法的插件，称为建模接口。程序使用这些方法在相邻模型之间交换信息。流量控制器以类似的方式实现。本文概述了该方法的重要组成部分：网络描述、需求描述以及建模和控制接口。我们包括测试，证明了成对的宏观、中观和微观模型之间的拥塞传播。Open Traffic Models 是这些概念的开源实现，可在 https://github.com/ggomes/otm-sim 获得。
