Eina d'avaluació i simulació per al monitoratge del trànsit en xarxes delimitades amb suport a la presa de decisions

Abstract

El transport sempre ha estat un sector molt important pel progrés de la societat. Ens ha permès intercanviar recursos, idees i serveis. En el segle passat, un període de grans revolucions i canvis, es va incorporar la massificació dels vehicles. Això ha donat lloc a la creació i el desenvolupament de les vies, que han ocasionat la implementació de normatives i l'addició d'elements característics com són els semàfors, els passos de vianants o les rotondes, i també de les normes de trànsit que fan possible una circulació més segura i ordenada. L'increment en la densitat de vehicles en les infraestructures ha suposat la congestió de les vies, amb la consegüent reducció del seu rendiment i la necessitat constant d'adaptació per cobrir les demandes creixents que hi apareixen. Un dels principals reptes és l'impacte ambiental, que es manifesta a través d'alguns efectes com: les emissions dels vehicles, l'obtenció de recursos, la qualitat de l'aire, la gestió dels vehicles al final de la seva vida útil i les conseqüències en l'àmbit atmosfèric. D'acord amb el que comporta un estudi de trànsit i aquests reptes, l'objectiu principal és proposar un entorn de treball capaç de traslladar a l'entorn digital aquestes infraestructures amb els seus elements més característics, on el sistema facilitarà valorar i comparar els resultats per prendre decisions més informades en la millora de les vies. Com a resultat, s'ha aconseguit la creació d'un sistema de simulació integrat, que permet traslladar de forma semiautomàtica l'àrea d'estudi al món digital, poder fer i guardar les modificacions necessàries, generar alternatives al circuit original, simular les infraestructures, verificar el seu funcionament, extreure mètriques, visualitzar-les a través de gràfiques o mapes de calor i comparar-les entre elles. La principal contribució d'aquest projecte es troba en el sistema desenvolupat, que pot ser un suport útil per a l'avaluació i millora d'infraestructures viàries des del punt de vista d'eficiència, però també ambiental a través de la captació de detalls com el consum energètic, les emissions generades o el consum dels combustibles fòssils.

Transportation has always been a fundamental sector for the progress of society. It has allowed us to exchange resources, ideas, and services. In the last century, a period of great revolutions and changes, the widespread adoption of vehicles occurred. This led to the creation and development of roads, which resulted in the implementation of regulations and the addition of characteristic elements such as traffic lights, pedestrian crossings, or roundabouts, as well as traffic rules that enable safer and more organized circulation. The increase in vehicle density on infrastructures has caused road congestion, resulting in a reduction in performance and the constant need for adaptation to meet the growing demands that arise. One of the main challenges is the environmental impact, which manifests through effects such as: vehicle emissions, resource extraction, air quality, the management of vehicles at the end of their useful life, and atmospheric consequences. In line with what a traffic study involves and these challenges, the main goal is to propose a work environment capable of transferring these infrastructures with their characteristic elements to a digital environment, where the system will allow evaluating and comparing the results to make more informed decisions for the improvement of roads. As a result, an integrated simulation system has been developed, which allows for semi-automatically transferring the study area to the digital environment, making and saving necessary modifications, generating alternatives to the original circuit, simulating the infrastructures, verifying their operation, extracting metrics, visualizing them through graphs or heatmaps, and comparing them against each other. The main contribution of this project lies in the developed system, which can be a useful tool for evaluating and improving road infrastructures from both an efficiency perspective and an environmental one, by capturing details such as energy consumption, generated emissions, or fossil fuel consumption.
