Managing traffic in a large city has become a topic of great interest in both politics and science. The costs of poor traffic management have been quantified as losses equal to millions of dollars, not counting the unquantifiable value of the time that a person loses in traffic jams. Intelligent transport systems (ITS) offer a set of innovative solutions specific to the management of different modes of transport. This article focuses on the development of an ITS for the city of Quito that allows smart decisionmaking to direct heavy haul transporters that want to enter the city via one of its main access routes. Technologies such as Sensor Web Enablement (SWE), in association with the Message Queuing Telemetry Transport (MQTT) communication protocol, facilitate the development of a vehicular management platform/system capable of sending notifications in real-time and issuing instructions to drivers regarding traffic delays along routes, average speeds, etc. The system supports a network of heterogeneous sensors accessible through the web. It can integrate any device that uses HTTP protocol. Time interval and location range testing have been undertaken to refine the accuracy of the system and make it adaptable to any geographic situation. The system allows communicate with the server through MQTT or through web services, using technologies such as: MongoDB and GeoJSON. One of the most relevant results is that the degree of accuracy of the system is within appropriate ranges when compared to commercial applications such as Google Maps and Waze.

Nowadays, the free movement of people and goods within the European Union is one of the topical issues. Each member state and border practitioner exploits its own set of assets in their goal of border surveillance and control. States have invested significantly in these assets and infrastructures necessary to manage and control the transit in the border areas. As new capabilities and assets become available and as current Command and Control (C2) systems become older, border control practitioners are faced with the increasing challenge of how to integrate new assets, command and control all of them in a coordinated and coherent way without having to invest in a completely new C2 systems built from the ground up. Therefore, and bearing in mind that the systems already developed up to date are very old and are not framed in a global standard data model, it has been identified, on one side the need to define a platform that allows to interact with multiple UxVs (land, sea and air), and on the other, unify all data models so that it can globalize and generate a much more concise analysis of what happens in places of conflict.
