The increasing capabilities and decreasing cost of information and communication technologies (ICTs) are enabling new categories of vehicular telematics applications, such as wireless drive-through (WDT) services, in which an external service provider provides services to in-vehicle occupants via a wireless connection. Most telematics systems rely on proprietary protocols for data exchange between an in-vehicle client and its external counterpart in individual applications, making it difficult to share data-exchange methods among applications. Sharing dataexchange methods is important because it allows a rapid return on ICT investments. In this paper, we study the data-modeling issues for data exchange between an in-vehicle client and its service provider for WDT services. We present a novel data model that captures the main characteristics of data exchange for the WDT application family, using a formal mathematical representation and an intuitive graphical representation. We show that the proposed data model provides generality for such data exchange. In addition, we propose several optimization techniques based on the data model to minimize user interaction so that a good usability can be achieved. Our simulations and analysis demonstrate that the proposed data model and relevant optimization techniques are promising in supporting efficient WDT applications.

RDS-TMC is a technology for distributing traffic information over the air. Despite its age, its popularity is still growing and is in many countries being freshly implemented. Because the way the information is encoded into RDS data is complex, it is quite difficult to objectively test and evaluate any RDS-TMC service; many times the evaluation simply states "it works" or "it does not work" on some particular device. This paper describes our approach to the conversion of raw RDS data into XML, which is much easier to understand and evaluate. We describe the format of XML and also mention possible technologies and tools which could help evaluating the information stored in these files, like XQuery, BaseX, etc. The described solution was used in real-life tests of three services: country-wide service in Czech Republic, regional service in Prague and pilot testing in Poland.

“…In the well defined infrastructure, vehicles can receive messages from various information sources. First of all, vehicle can receive data from information center via wireless communication or broadcasting (e.g., 3G, FM, Dedicated Short Range Communications(DSRC) [2], [5], [10] and DVB-T [6]) as shown in Fig. 1 hikaruu@seed.net.tw moving.…”

Vehicular wireless communication for real-time or emergent events notification is an important issue in VANETs. In this article we construct an integrated architecture for the implementation of dynamic routing/navigation application in VANET environment using iWCU -a WAVE/DSRC device developed by ITRI 1 of Taiwan. The Dynamic navigation field test in VENET using a WAVE/DSRC On-board-Unit(OBU) and a WAVE/DSRC Road-Side-Unit(RSU) as the network node is examined. OBU provides dynamic navigation service for driver when receiving the real-time traffic information from RSU. The loopback detection method is adopted to detect re-broadcasting packets when a forward request in real-time needed in this study. As result, real-time packets transmission for dynamic navigation application with high mobility situations are delivered efficiently in testing results.(
