This paper describes WAVE (Wireless Access in Vehicle Environment) system design especially for UHF frequency band. Especially 700MHz band is currently used for analog TV terrestrial service in the world and it is going to be terminated soon or done in the world. Japan will terminate 700MHz band analog TV in July 2011 and it is going to assign new application system from 2012. In terms of WAVE system, IEEE802.11p standard is available in currently world wide standardization activities and it is focused on 5.9GHz frequency band. However 700MHz band has more technology advantage not only longer range communication but also hidden vehicles access such as in urban area. In Japan, MIC (Ministry of Internal Affaires and Communications) is going to assign ITS (Intelligent Transport System) frequency at 720MHz band with 10MHz bandwidth and started several field tests. In order to use 700MHz technology advantage, authors propose optimized 700MHz WAVE system architecture design and it will be useful for future standardization.

Future driver assistance systems need to be more robust and reliable because these systems will react to increasingly complex situations. This requires increased performance in environment perception sensors and algorithms for detecting other relevant traffic participants and obstacles. An object's existence probability has proven to be a useful measure for determining the quality of an object. This paper presents a novel method for the fusion of the existence probability based on Dempster-Shafer evidence theory in the framework of a highlevel sensor data fusion architecture. The proposed method is able to take into consideration sensor reliability in the fusion process. The existence probability fusion algorithm is evaluated for redundant and partially overlapping sensor configurations.

This paper presents the results of a set of extensive experiments carried out in daytime and nighttime conditions in real traffic using an enhanced or extended Floating Car Data system (xFCD) that includes a stereo vision sensor for detecting the local traffic ahead. The detection component implies the use of previously monocular approaches developed by our group in combination with new stereo vision algorithms that add robustness to the detection and increase the accuracy of the measurements corresponding to relative distance and speed. Besides the stereo pair of cameras, the vehicle is equipped with a low-cost GPS and an electronic device for CAN Bus interfacing. The xFCD system has been tested in a 198-minutes sequence recorded in real traffic scenarios with different weather and illumination conditions, which represents the main contribution of this paper. The results are promising and demonstrate that the system is ready for being used as a source of traffic state information.

In this paper, we propose a novel approach to deal influence of own vehicle behavior to driving scene which called “interactions” with surrounding traffic participants. Recently, various advanced driver-assistance systems (ADAS) have been proposed. In these ADAS, however, it is not sufficiently considering the influence of own vehicle behavior. With a novel driver assistance system based on the traffic interactions, each vehicle keeps not only own vehicle but also surrounding space in safety and comfortable, such as, Lane Change Assist for reducing traffic jam. We estimate the interactions from the behavior data of the traffic participants using Bayesian filtering techniques. Efficiency of the novel driving support with the interactions is evaluated in simple traffic simulations. In the simulated experiments, our approach improves traffic flow 140% smoother than without the driving support. Constructions of more detail traffic interaction models and demonstrations of effectiveness using real-vehicles are important feature works. It is also important that the development of the specific ADAS application based on traffic interaction.

Video-based driver assistance systems are a key component for intelligent vehicles today. Applications for lane detection, traffic sign recognition, and collision avoidance have been successfully deployed in cars and trucks. State-of-the art algorithms rely on machine learning and therefore depend on invariance conditions, e.g. a fixed image perspective. In order to apply current modules in two-wheeled vehicles one needs to determine the roll angle, i.e. the angle between the road plane and the slanted vehicle. It can either be used for parametrisation of the algorithms or for rotation of the video image back to a horizontal alignment. Using an inertial measurement unit to acquire this data is unreasonably expensive. We propose a video-based module that estimates the current roll angle based on gradient orientation histograms to overcome this flaw. Due to the visual structure of a traffic scene we are able to derive possible roll angles from the gradient statistics by correlation with learnt data. Analogously, we estimate the roll rate by correlating subsequent image statistics and stabilise both measures within a linear Kalman filter. Experiments on real image data from various test scenarios show high accuracy of the proposed approach. Thus, estimating the roll angle / rate from video only, enables us to employ established video-based assistance modules for two-wheeled vehicles without any additional hardware expense.

Besides the use for classical navigation applications, precise vehicle self-localization will be a key requirement for many future advanced driver assistance systems (ADAS). Current systems available do not provide the accuracy and availability needed for vehicle safety applications at reasonable sensor costs. This paper proposes a novel approach for vehicle self-localization using cooperative landmarks integrated into infrastructure. A prototype system, performing Angle-of-Arrival (AOA) and Round-Trip Time-of-Flight (RTOF) measurements at 2.4 GHz, was designed and integrated into a test vehicle. Based on experimental results, a robust position filter was derived. The system performance, tested at an urban crossing with two cooperative landmarks, demonstrated the feasibility of a low-cost localization system that achieves lane accurate positioning without dependence on satellite signals.

Reliability is the most important criterion in the design of advanced driver assistance systems. In this context the use of probabilistic activation conditions for e.g. driver warnings or automatic system interventions allows handling of noisy input data and thus reduction of false alarms. In this paper we present a novel computation method for the time metric Time-To-Collision (TTC) in complex traffic situations. Our algorithm is based on a computationally efficient, non Euclidean distance function between extended objects. This function is approximated by a interpolating polynomial and TTC is computed by finding a root of this polynomial. The main contribution of this work is the determination of the collision probability. The calculation of this probability relies on the minimum of the aforementioned distance function and statistical linearization via the Unscented Transformation. The accuracy of the presented method was proven in the simulation using the example of a turning left scenario.

In this study, collision-prevention support braking was used as an example, and a methodology for estimating the collision mitigation ratio using this system is discussed. A method for analyzing the collision-mitigation ratio is discussed through a time series Monte-Carlo simulation based on the integrated error of driver and system [1][2]. First, driver performance in terms of braking timing and deceleration level for collision avoidance was analyzed in a driving simulator when the control timing of the braking-support system was changed. Next, a driver model simulating braking operation, when a preceding vehicle started slowdown was constructed. Through time series simulations using this driver model, the frequency of collisions with a preceding vehicle and the collision velocity were estimated. One result analyzed through this simulation study based on the integrated error of driver and system considering the driver's risk taking behavior during the use of the system estimates that the frequency of collisions decreased from 6.64×10−1 to 1.00×10−5 when the driver used the driving support system for collision avoidance. Although further verification regarding the driver error and system error will be necessary, a methodology for evaluating effectiveness of driving-support system is shown in this study.

A detailed study of cultural differences can facilitate the process of introducing a product into a particular market. Such an analysis can be used to decide to what extend a global design of a product needs to be considered and which subsequent measures related to localization or adaptation to a specific target culture need to be taken. In the particular case of a Driver Information System (DIS), cultural preferences in the interaction with the user interface could lead to a decrease of the ease of navigation through an insufficiently localized human machine interface depending on the culture. In this study we examine cultural differences on the interaction with the menu of a DIS through a cross cultural survey. The web based comparative multilingual questionnaire was analyzed to determine the impact of the user's culture on preferences in the design of the menu structure of a system to be used in a vehicular environment. Results confirm the existence of cultural differences among users from Germany, USA and Japan. In particular we show heterogeneity that affects the menu structure design of the DIS' user interface. The implications for the design and adaptation of entertainment related functions in the DIS' menu structure are outlined.

In vehicular applications based on motion-stereo using monocular side-looking cameras, pairs of images must usually be rectified very well, to allow the application of dense stereo methods. But also long-term installations of stereo rigs in vehicles require approaches that cope with the decalibration of the cameras. The need for such methods is further underlined by the fact that offline camera calibration is a costly and time-consuming procedure at vehicle production sites.
