The paper deals with two different heuristic approaches for solving the problem of optimal location of traffic count sections (OLTCS), which is a crucial issue of the design of area wide ITS traffic monitoring centers. The first method applies deterministic rules on O/D flows and O/D pairs coverage. The second is based on a genetic algorithm (GA). Both are(More)
High density radio base station networks for mobile communication systems (i.e. GSM, GPRS, UMTS) are nowadays available, especially in populated urban areas and along the major roads and communication routes. Such radio networks encompass a high number of microwave radio links of different lengths (from hundreds of meters to dozens of kilometers), depending(More)
1 BACKGROUND In the last three decades various researchers had been facing the problem of maximizing global network performances by optimizing traffic signals. The main difficulty of the problem arises from the existing interaction between network performance and users' route choice. In fact, drivers make their travel choices in order to minimize their own(More)
The paper develops a mesoscopic emission model for signalized intersections that takes into account the dynamic variability of traffic conditions. It starts from an analytical model based on Akcelic theory and it permits to distinguish between vehicles in queue and vehicles entering/exiting the queue (deceleration and acceleration phases) using data derived(More)
The capability to detect and/or forecast traffic conditions is of utmost importance in road management applications. Recent advances in technology have made available numerous new monitoring systems exploiting larger fleet of probe vehicles. Together with traditional volume and time mean speed measurements relative to a local section monitored continuously(More)
The paper illustrates methodology and preliminary results obtained in the project of basic research “Interaction between signal settings and traffic flow patterns on road networks”, funded by the Italian Ministry of University and Research. The object of the project is to develop a general procedure to study, model and solve the problem of the optimal road(More)
The paper describes the objectives, the methodology and the preliminary results of the research project “Interaction between signal settings and traffic flow patterns on road networks”, granted by the Italian Ministry of University and Research with the Fund for Investments on Basic Research (FIRB). The project joins three research units, belonging(More)
