Title: Experimental application to a water delivery canal of a distributed MPC with stability constraints Authors: Lemos, João; Igreja, José; Cadete, Fernando; Rijo, Manuel; Rato, Luís Editors: Hinkelmann, R.; Nasermoaddeli, M.; Liong, S.; Frohle, D.; Daemrich, K. Abstract: In this work, a novel distributed MPC algorithm, denoted D-SIORHC, is applied to upstream local control of a pilot water delivery canal. The D-SIORHC algorithm is based on MPC control agents that incorporate stability constraints and communicate only with their adjacent neighbors in order to achieve a coordinated action. Experimental results that show the effect of the parameters configuring the local controllers are presented.

Title: M-Traffic: Mobile Traffic Information and Monitoring System Authors: Romão, Teresa; Rato, Luís; Almada, Antão; Dias, António Eduardo Abstract: Traffic information is crucial in metropolitan areas, where a high concentration of moving vehicles causes traffic congestion and blockage. Appropriate traffic infor- mation received at the proper time helps users to avoid unnecessary delays, choos- ing the fastest route that serves their purposes. This work presents Mobile Traffic (M-Traffic), a multiplatform online traffic information system, which provides real-time traffic information based on image processing, sensor’s data, and traveller behaviour models. This system has a modular architecture that allows it to easily be adapted to new data sources and additional distribution platforms. In order to estimate route delay and feed the optimal routing algorithm, a traffic microscopic simulation model was developed, and simulation results are presented. This mobile information service ubiquitously provides users with traffic information regarding their needs and preferences, according to an alert system, which allows a personal- ized pre-definition of warning messages.
