Algorithms for pedestrian detection based on multi-cue computer vision systems have become increasingly sophisticated and have been shown capable of achieving high detection performance for moderate range of applications. In particular, it has been demonstrated that a key successes lies in the integration of both single frame and over time measured cues and via building up additional object categories consisting of vehicles and stationary background structures. However, most of extensive field tests were made with a use of high contrast, good resolution, large filed of view, distortion free mounted cameras. In this paper we use a standard vehicle with a built-in rear view camera for parking space detection that has moderate contrast, low resolution, limited field of view and large distortions. For the evaluation of multi-cue pedestrian recognition system, we used a database of more than 300 typical sequences from 30 seconds to 30 minutes of 30 km/h limited drive both in Europe and Japan. Using that database and semi-automatically collected ground truth, several experiments were carried out to determine how pedestrian detection performance evolves with respect to distance from vehicle to pedestrian, vehicle's speed and illumination conditions. The results and interpretation of these experiments will be described in this paper.

In this paper, we present the design and calibration of two antenna arrays, of 4 active elements each, at 3.5 GHz for double directional channel measurements. This frequency band is used for wireless local loop (WLL) applications. The beam patterns of these two arrays are measured in anechoic chamber. A calibration algorithm is applied on these measurements for high resolution 4times4 MIMO (multiple input multiple output) channel sounding. Results obtained after the beam patterns calibration are presented. The importance of this work is shown by ESPRIT simulations for better multipath parameters estimation.

The tracking of radar targets in automotive applications often relies on certain constraints to the movement of objects. For example, the objects of interest in an ACC system (adaptive cruise control) are other vehicles that are positioned straight ahead and moving in approximately the same direction as the observer. In this case, a single radar measurement (distance to target, bearing angle and Doppler velocity) contains -neglecting measurement noise -full information about the position (by distance and angle) and the movement state. Thus, the initialization of tracks can be done based on a single measurement. Without the mentioned assumption, no information about the movement direction of the object is contained in a single measurement. Theoretically, at least two measurements are necessary to extract information about the object movement direction. But due to severe measurement noise and quantization, even three or more measurements may contain misleading information about the movement state. In this paper we present an initialization procedure for radar target tracking without any constraints to object movement. In the first cycles of a new track, the state estimation is computed by a linear regression method. After that, the track state is handed over to a Kalman filter which does the tracking for the rest of the track's lifetime.

The future European railway system will have to exhibit dramatically improved overall efficiency and performance. In order to achieve this high level goal, the InteGRail project aims to create a holistic, coherent information system, integrating the major railway sub-systems. In this paper we present ICOM, a framework for intelligent communication in InteGRail. This framework follows an application driven approach to integrate the heterogeneous railway networks and to deliver advanced end to end communication services combining QoS, mobility and security via business oriented interfaces. It defines a reference model for further interoperability standardisation in railway communication.

A scientific coordination group devoted to intelligent transportation systems has been set up in the Brittany region, called GIS ITS Bretagne. The focus of this paper is on the LoCoSS project, one of the two first projects launched by the GIS, which aims at improving the efficiency and safety of terrestrial and maritime rescue operations through the use of geo-localization and wireless communication technologies. The paper gives an overview of the project and presents its progress after the first year, particularly in terms of geographical data management and indoor localization of the intervening firemen.

Millimetre-wave devices for intelligent transport systems (ITS) are among the research topics for road-vehicle communications (RVC) and inter-vehicle communications (IVC). Up to now, the only commercialized millimetre wave ITS devices are automotive cruise control radars (ACC), as those manufactured in France by Autocruise Company. The idea which we are working on is to implement a communication function on the AC20 radar from Autocruise in order to improve road safety, transport efficiency, comfort as well as environmental conservation. The reuse of the RF functions that already exist on the radar makes it possible to reduce the new equipment costs and the frequency band used (millimetre waves) allows a high traffic to be run out.

In this paper, we study safety applications in Vehicular Ad hoc Networks (VANETs). More specifically we concentrate on emergency situations after a car crash in a platoon of vehicles which have wireless transmission capabilities. In order to avoid multiple collisions, vehicles should exchange emergency information as quickly as possible. To extend the area in which the emergency information is sent, they must relay it. In this article, we study various techniques to disseminate emergency data within a platoon of cars. We examine three different techniques : the pure flooding, the multipoint relay (MPR) diffusion mechanism of OLSR [1] and a geographic aware flooding technique as described in [2]. Different realistic scenarios are considered; we scrutinize various parameters such as vehicle density, and background traffic load.

One of the most important functions of VTS is to resolve collision among vessels by giving anti-collision advice. In the past, the advice was generated by manual ARPA plotting which may lead to heavy workload. Recently, AIS are widely deployed on vessels. Therefore, VTS can collect more accurate data about the movement of the vessels than before. That makes it possible to generate anti-collision advice automatically. In this research, we built a cooperative multi-agent negotiation system to generate anti-collision instructions for VTS operators. This system can create a software agent for each vessel, constantly monitors their movement, detects the collision risk, and initiates a negotiation process if collision risk exists. Agents negotiate with each other complying with monotonic concession protocol to make themselves more and more concessive until an agreement is achieved. Simulation results show that this system can generate safe and economic anti-collision instructions for VTS operators, and the application of this research shall improve the efficiency of VTSs.
