Allan Mariano de Souza,Celso A. R. L. Brennand,Celso A. R. L. Brennand,Roberto Sadao Yokoyama,Erick Donato,Edmundo R. M. Madeira,Leandro A. Villas +6 more
TL;DR: This article presents a classification, review, challenges, and future perspectives to implement a traffic management system that addresses the problem of congestion in cities.
Proceedings ArticleDOI
Real-time path planning to prevent traffic jam through an intelligent transportation system
Allan Mariano de Souza,Roberto Sadao Yokoyama,Guilherme Maia,Antonio A. F. Loureiro,Leandro A. Villas +4 more
TL;DR: An intelligent traffic system called CHIMERA is proposed, which improves the overall spatial utilization of a road network and also reduces the average vehicle travel costs by avoiding vehicles from getting stuck in traffic.
Journal ArticleDOI
ICARUS: Improvement of traffic Condition through an Alerting and Re-routing System
Allan Mariano de Souza,Roberto Sadao Yokoyama,Azzedine Boukerche,Guilherme Maia,Eduardo Cerqueira,Antonio A. F. Loureiro,Leandro A. Villas +6 more
TL;DR: Simulation results show the effectiveness of ICARUS in calculating new routes and disseminating them to vehicles approaching a congested area and it reduces the travel time, fuel consumption, and CO emissions of vehicles in urban environments when compared to existing approaches.
Proceedings ArticleDOI
Scorpion: A Solution Using Cooperative Rerouting to Prevent Congestion and Improve Traffic Condition
Allan Mariano de Souza,Roberto Sadao Yokoyama,Leonardo Castro Botega,Rodolfo I. Meneguette,Leandro A. Villas +4 more
TL;DR: An intelligent traffic cooperative routing application called SCORPION is proposed, which improves the overall spatial utilization of a road network and also reduces the average vehicletravel costs by avoiding vehicles from getting stuck in traffic.
Journal ArticleDOI
An architecture for secure positioning in a UAV swarm using RSSI-based distance estimation
TL;DR: The fundamental principles of beaconing-based communication are applied to calculate the distance between the nodes on the basis of the received signal strength indicator (RSSI), and results showed that the correct position determined by RSSI was better than the image processing from stereo cameras.
