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.

A road environment recognition system is presented. First, lane lines are detected based on our proposed Gaussian comparison function. Then a road prospective model is built on the basis of a new Gaussian semi-sphere approach to detect vanishing point. Using this model, three road parameters are computed, i.e. vehicle's transverse bias, yawing angle and the road slope angle. Obstacles such as vehicles in front of the current lane are also extracted. Simulation experiments prove the effectiveness of the system.

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.

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.

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.

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.

In sensor networks, a data query can be named according to the physical attributes, and is generally diffused throughout the network to retrieve sensor data. However, the direct distributions of queries into the network will cause a large traffic overhead and high energy consumption. In this paper, we propose a localized query forwarding scheme based on the processing of query's name. In contrast to the conventional distributions of data query message, a query's name is resolved into the IDs of corresponding group of sensor nodes before being distributed to the network. Therefore, the query is efficiently forwarded into the network within a localized area. The proposed approaches highly reduce the query overhead in the network and save the energy consumption of sensor nodes.

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.
