Vehicular Ad Hoc Networks (VANETs) are expected to be the next big step towards safer road transport, supporting applications to exchange information between vehicles. To develop novel applications for this area a high number of tests, considering all traffic situations, are demanded. However, it is unfeasible to reproduce these tests in real life, by the fact that any failure on the applications would cause severe impacts on transport system safety and could risk human lives. Thus, this paper presents the concept, model, and validation for InTAS, a realistic traffic scenario for Ingolstadt. InTAS road topology accurately represents Ingolstadt real road map. Elements such as buildings, bus stops, and traffic lights were added to the map. Twenty traffic lights systems were simulated according to the real program deployed on the traffic lights. Traffic demand was modeled based on the activitygen method, considering demographic data and real-traffic information. The city public transport system was also simulated accordingly to bus time-tables and their routes. The simulation step was implemented considering the best value for device.rerouting.probability, which was defined by evaluating InTAS output and real traffic data. The scenario was validated by comparing real-traffic data from 24 measurement points with InTAS simulation results.

InTAS-SUMO的因戈尔施塔特交通场景

车载自组织网络（VANET）有望成为朝着更安全的道路运输迈出的下一步，这将支持在车辆之间交换信息的应用程序。为了开发该领域的新颖应用，需要考虑所有交通情况的大量测试。但是，由于应用程序的任何故障都会对运输系统的安全造成严重影响并可能危及生命，因此在现实生活中重现这些测试是不可行的。因此，本文介绍了InTAS的概念，模型和验证，InTAS是Ingolstadt的现实交通场景。InTAS道路拓扑可准确表示Ingolstadt真实路线图。建筑物，公交车站和交通信号灯等元素已添加到地图中。根据部署在交通信号灯上的实际程序模拟了20个交通信号灯系统。在考虑人口统计数据和实际交通信息的基础上，基于activitygen方法对交通需求进行建模。还根据公交车时刻表及其路线对城市公共交通系统进行了模拟。仿真步骤是在考虑设备，路由，概率的最佳值的情况下执行的，该值是通过评估InTAS输出和实际流量数据来定义的。通过将来自24个测量点的真实交通数据与InTAS仿真结果进行比较来验证该方案。通过评估InTAS输出和实际交通数据来定义。通过将来自24个测量点的真实交通数据与InTAS仿真结果进行比较来验证该方案。通过评估InTAS输出和实际交通数据来定义。通过将来自24个测量点的真实交通数据与InTAS仿真结果进行比较来验证该方案。
