Trying to provide safer and more efficient transportation solutions, the need for reliable and efficient communications is increasing in ITS (Intelligent Transportation Systems) use cases such as collaborative road data collection, driver information systems, infotainment or fully driverless vehicles. Applications that rely on vehicle-infrastructure (V2I) and vehicle-vehicle (V2V) communications have different requirements and would benefit from a widely deployed common standard for the exchange of data. IP (Internet Protocol) is thus advocated as the convergence layer between the various available wireless technologies available on the market. This paper surveys the methods employed in the Imara team to provide a stable communication environment allowing driverless vehicles to interact with each other in several scenarios where information sharing is required. An account of how the solutions are integrated and how well they behave together in live experiments is given.

Vehicle-to-vehicle and vehicle-to-infrastructure wireless communications are currently under development to improve traffic efficiency and safety. The time-critical nature of road safety applications imposes the need to accurately dimension the operation and performance of wireless vehicular communication systems. Given that radio propagation modeling has been shown to importantly affect the performance of traditional mobile and wireless communication systems, this work investigates its impact on the dimensioning of traffic safety wireless vehicular communications by separately analyzing the contributions of pathloss, shadowing and fast fading.

In the past years, though communication became more and more available and efficient (GPRS, UMTS, Win...), very few traffic applications have been implemented in the real life, all of them using a central server (V2C). Cooperative systems using inter-vehicular communication (V2V) represent the next step, but the deployment roadmap remains unclear, even though safety is strongly pushed. This paper aims at presenting current integration and testing work performed at the LaRA lab for inter-vehicular communication. From the characterization of communication performance, we analyze the suitability of a set of applications. Our aim is to show what kind of application can be deployed with current hardware and software.

To solve the aggravating traffic problems in China, from the beginning of 2007, a program called traffic monitoring and processing technique based on aerial platform (TMAPTBOAP) supported by the hi-tech research and development program of China is undertaken by Beijing University of Aeronautics and Astronautics. If everything goes smoothly, the system developed in this program may be used during the 2008 Beijing Olympic Games. The architecture designed for this system will be introduced in this paper.

In this paper we propose a new system to detect obstacles round a vehicle for intelligent driver assistance system. The system consists of a pair of panoramic annular lens (PAL) cameras, which are installed on the top of the vehicle. The panoramic annular lens can project the view of the entire 360 degrees around the optical axis onto an annular plane. Two cameras which are fixed properly can capture all view of the surroundings of the vehicle. They are calibrated by using the spherical perspective projection model to unwrapped the conventional perspective image without distortion. A front panoramic image and a back panoramic image of the vehicle form a vehicle dynamic panoramic map (VDPM). A driver can watch the scene in any direction of the vehicle through the VDPM, which will make the drive safer. Three coordinates systems are established in order to obtain the obstacle position information from the vehicle. We create a virtual binocular vision situation using the video stream from each one panoramic camera. The binocular analysis technique with area-based correlation is used to recognize the obstacle and compute the distance from the vehicle. The experiment result shows the basic feasibility of this system. It is believed that a panoramic annular lens camera will play an important role in the future of intelligent driver assistance systems.

An IEEE 802.16 MESH network is envisaged for multihop inter-ship communications and its MAC performance is investigated by simulations. Results show that, with respect to throughput, delivery ratio, and average delay, when sea wave direction is perpendicular to the nodes connection direction, good MESH MAC performance can be achieved in sea states 1.0, 3.0, 5.0, and 7.0, for both 1-hop and 2-hop CBR connections with hop distance more than 10 km. With relative parallel wave direction, in sea states 1.0 and 3.0, the MAC performance is close to that of the perpendicular case while it drops in sea state 5.0 and 7.0; however the delivery ratio can still be more than 60 percent. With increase in 1-hop CBR data flows, the network throughput increases linearly in sea state 1.0; but the increase in throughput becomes slower in higher sea states.

ITS components are more and more software components, so ITS design research seems to join software engineering one. But if communication middlewares are well suited to standard software design, they become insufficient when software aims mobility, and especially ITS. We propose a solution based on a multi-model approach, able to simplify the work of ITS software designers, and to ensure communication between distributed components, however is the quality or availability of the network connection. We also present an application work, applying our multi-model approach to providing Internet access in trains.

Multipath is an issue of paramount importance in the GNSS context, and the dominant error source for the Delay Lock Loop (DLL) used for code tracking. This paper introduces an optimized Multiple Gate Delay (MGD) code tracking implementation in the modified GRANADA Bit-true Software Receiver Simulator. Then the tracking performance of the optimized MGD structure is presented via GRANADA simulation results. This tracking performance is also compared with the tracking performance of High Resolution Correlator (HRC) and of the narrow correlator or narrow Early-Minus-Late (nEML) structures. The tracking performance criteria include Multipath Error Envelopes (MEEs) and Root Mean Square Error (RMSE) for both multipath static channels and fading channels. It is shown that the optimized MGD structure has a better performance than nEML and HRC in the multipath channels, and that the GRANADA Bit-true Software Receiver Simulator is a useful tool for testing the performance.

Accompanying with the rapid spread of various ITS applications, most of current existing systems were designed under particular purpose but less attention on cooperating with other systems or devices. As the trends, it is widely believed that ITS is no longer a simple standalone application in the vehicle. How to provide a convenient and flexibility mechanism to integrate multiple applications seamlessly has became an urgent issue. In this paper, we propose a SOAP-based IPv6 Middleware platform to establish a unified framework which can easily integrate all the services or messages provided by different ITS applications or devices. The proposed Middleware is composed of four major parts: communication management, device management, object management and data management. However, it involves many different domain knowledge and techniques in practical implementation. In this paper we are primarily concerned with one of the key techniques when build up this middleware, namely SOAPv6 (Simple Object Access Protocol over IPv6). Furthermore, our preliminary prototype telematic system will also be demonstrated in this paper.
