Vehicular ad hoc networks (VANETs) have gained interest because of their applicability and significance in the fields of traffic management, road monitoring and safety, infotainment, and on-demand services. Route planning in vehicular networks based on efficient collection of real-time data can effectively mitigate traffic congestion problems in urban areas. Furthermore, real-time data is shared by using an effective sharing mechanism to avoid redundancy of the collected information. However, dynamic route replanning and effective sharing mechanisms based on real-time data are still challenging problems. Therefore, the aim of this article is to describe route planning and data dissemination in real time using the Internet of Things paradigm. This objective is achieved by a novel data dissemination technique for information sharing among the roadside units in a hybrid VANET intelligent transportation system (Hybrid- VITS). Hybrid-VITS comprises VANETs, vehicular traffic servers, and a 5G-based cellular system of public transportation. By considering the traffic congestion in urban areas, the optimal path is calculated to replan routes based on the k shortest path algorithm, and a load balancing technique is adopted to avoid further congestion.

使用物联网的城市场景的实时路线规划和数据发布

车载自组织网络（VANET）由于其在交通管理，道路监控与安全，信息娱乐和按需服务领域中的适用性和重要性而引起了人们的兴趣。基于有效实时数据收集的车辆网络中的路线规划可以有效缓解城市地区的交通拥堵问题。此外，通过使用有效的共享机制来共享实时数据，以避免所收集信息的冗余。但是，基于实时数据的动态路线重新规划和有效的共享机制仍然是具有挑战性的问题。因此，本文的目的是使用物联网范例实时描述路线规划和数据分发。该目标通过一种新颖的数据分发技术来实现，该技术用于在混合VANET智能交通系统（Hybrid-VITS）中在路边单元之间共享信息。Hybrid-VITS包括VANET，车辆交通服务器以及基于5G的公共交通蜂窝系统。在考虑城市交通拥堵的基础上，根据k最短路径算法，计算出最优路径对路线进行重新规划，并采用负载均衡技术避免拥塞。
