“…We implemented DDRX in a TMS called FASTER [37], where it segments the scenario in different districts (i.e., sub-regions) to aggregate the traffic information of the roads. Each vehicle collects and transmits data of average speed and identification of the pathways in its radio range through beacons.…”

Services that aim to make the current transportation system more secure, sustainable, and efficient constitute the Traffic Management Systems (TMS). Vehicular Ad hoc Networks (VANETs) exert a strong influence for TMS applications, due to TMS services require data, communication, and processing for operation. Besides, VANET allows direct communication between vehicles, and data are exchanged and processed between them. Several TMS services require disseminated information among decision-making vehicles. However, such dissemination is a challenging task, due to the specific characteristics of VANETs, such as short-range communication and high node mobility, resulting in several variations in their topology. In this article, we introduce an extensive analysis of our proposed data dissemination protocol based on complex networks' metrics for urban VANET scenarios, called DDRX. Each vehicle must build a subgraph to identify the relay node to continue the dissemination process. Based on the local graph, it is possible to select the relay nodes based on complex networks' metrics. Simulation results show that DDRX offers high efficiency in terms of coverage, number of transmitted packets, delay, and packet collisions compared to well-known data dissemination protocols. Also, DDRX provides significant improvements to a TMS that needs efficient data dissemination.

Vehicular traffic re-routing is the key to provide better traffic mobility. However, taking into account just traffic-related information to recommend better routes for each vehicle is far from achieving the desired requirements of proper transportation management. In this way, context-aware and multi-objective re-routing approaches will play an important role in traffic management. Yet, most procedures are deterministic and cannot support the strict requirements of traffic management applications, since many vehicles potentially will take the same route, consequently degrading overall traffic efficiency. So, we propose an efficient algorithm named as Better Safe Than Sorry (BSTS), based on Pareto-efficiency. Simulation results have shown that our proposal provides a better trade-off between mobility and safety than state-of-the-art approaches and also avoids the problem of potentially creating different congestion spots.

“…De forma resumida, o foco do sistema MAESTROé minimizar os problemas causados pelo congestionamento de tráfego veicular de forma distribuída e sem comprometer a sua escalabilidade. A avaliação do sistema proposto foi realizada por meio de simulações comparando com outros sistemas da literatura [de Souza and Villas 2016, Doolan and Muntean 2017, Pan et al 2017] em diferentes requisitos. As avaliações de desempenho foram feitas sobre duas perspectivas: (i) avaliação de escalabilidade e (ii) avaliação do gerenciamento da mobilidade urbana.…”

O Sistema Avançado de Gerenciamento de Tráfego (ATMS) é cada vez mais utilizado por gestores de mobilidade urbana para aprimorar o gerenciamento de tráfego veicular. Muitos ATMS empregam soluções centralizadas devido à dificuldade de selecionar os veículos mais relevantes, em redes altamente dinâmicas, para detectar congestionamentos e sugerir rotas alternativas. Além disso, tais soluções nem sempre são escaláveis. Por outro lado, a solução distribuída necessita previamente segmentar todo o cenário para selecionar os veículos. Além disso, tal solução sugere rotas alternativas, de maneira egoísta, que podem levar ao congestionamento secundário. Com base nessas lacunas encontradas, foi proposto um sistema distribuído de gerenciamento de mobilidade urbana baseado no paradigma das redes sociais veiculares (VSNs) chamado MAESTRO. Tal paradigma surgiu a partir da integração dos dispositivos de comunicação sem-fio e das redes sociais no ambiente veicular. Assim duas diferentes abordagens podem ser exploradas em VSNs: Social Network Analysis (SNA) e Social Network Concepts (SNC). Ambas abordagens foram aplicadas no sistema MAESTRO. Os resultados das simulações mostraram que o uso dos SNA e SNC, no ambiente veicular, tem grande potencial em aumentar a escalabilidade do sistema e também aprimorar a eficiência no gerenciamento da mobilidade urbana.
