Abstract
The sustainable urban mobility of people and goods in a territory has become one of the major challenges which has recently gained much interest in several ICT research areas. In this context the Pegasus Project aims to provide reliable and timely information to improve the safety and the efficiency of vehicles’ and goods’ flows. To do this, it is necessary to collect and integrate large amounts of geo-located stream items coming from On Board Units (OBUs) installed on vehicles. The final aim is to exploit these information for providing end users with various services to enhance mobility.
We propose a data management solution where stream items coming from vehicles are processed and stored in a result container. The required data access functionalities are provided through an SQL-like query language enhanced with stream, event, spatial and temporal operators.
Finally, we propose several communication-saving techniques for Vehicle to Infrastructure (V2I) and Vehicle to Vehicle (V2V) communications in order to aggregate and reduce the data coming from vehicles.
