ElisaTM – Car to infrastructure communication in the field

Car to infrastructure (C2I) communication as an aspect of Intelligent Transportation Systems (ITS) is a topic that is currently under wide research. Most works however deal with theoretical analysis, simulative evaluation or closed testbeds. There are only a few publications describing real world application of C2I on real world streets with real world traffic.In this paper we present the results of initial tests and measurements performed in the testbed ElisaTM (Efficient Light Signal Adaptation Testbed Munich). The testbed consists of four intersections in a mostly residential area in Munich, Germany. The results include an analysis of data availability and data quality under different traffic conditions.
