M-Traffic - A Traffic Information and Monitoring System for Mobile Devices
Romão, Teresa; Rato, Luís; Fernandes, Pedro; Alexandre, Nuno; Almada, Antão; Capeta, NunoThis paper presents Mobile Traffic (M-Traffic), a multiplat- form online traffic information system, which provides real time traffic information based on image processing, sensor’s data and traveller be- haviour models. In order to estimate route delay and feed the optimal routing algorithm a traffic microscopic simulation model is developed and simulation results are presented. This mobile information service ubiqui- t...
Online data mining services for dynamic spatial databases I: system architectur...
Costa, Manuel; Sousa, Inês; Fonseca, Alexandra; Henriques, Diana; Rosa, Paulo; Franco, Ivan; Capeta, Nuno; Teixeira, Luis Miguel LopesThis paper describes online data mining services for dynamic spatial databases connected to environmental monitoring networks. These services can use Artificial Neural Networks as data mining techniques to find temporal relations in monitored parameters. The execution of the data mining algorithms is performed at the server side and a distributed processing scheme is used to overcome problems of scalability. To...
