The determination of the vehicle position at the lane level is an important challenge in road navigation that can bring new possibilities for collision avoidance or advanced driver assistance systems. An interesting approach of this problem is the combination of GNSS with enhanced maps that include precise lane information. This paper presents a novel method for map-matching and positioning at ...

We present a formal proof of collision avoidance for a simple distributed hybrid system consisting of an arbitrary finite number of cars on a one dimensional road. Our cars take actions independently from one another and without synchronization, thus behaving in a truly distributed manner. We allow cars to enter and exit the road. For the continuous dynamics, we show how differential invariants...

We present a mathematical model to predict pedestrian motion over a finite horizon, intended for use in collision avoidance algorithms for autonomous driving. The model is based on a road map structure, and assumes a rational pedestrian behavior. We compare our model with the stateof-the art and discuss its accuracy, and limitations, both in simulations and in comparison to real data.

prevention of infectious diseases during travel but also with the personal safety of travelers and the avoidance of environmental risks. The major content areas of travel medicine include the global epidemiology of the health risks to the traveler, vaccinology, prevention of disease and pretravel counseling. Many of these risks can be minimized by precautions taken before, during and after trav...

In the recent works either the obstacle avoidance of robot in the 2-D unconstrained environment or the wall following behavior of mobile robot in constrained motion has been discussed. In some of them target alignment behavior has been discussed. Also the integration of some but not sufficient behaviors have been discussed in some research works. But all of the behaviors have not yet been integ...

The introduction of new technologies such as autonomous intelligent cruise control or collision avoidance schemes to road vehicles necessitates a high degree of robustness and reliability. Whilst very accurate range estimates may be recovered using conventional sensors, e.g. millimetric radar, these typically suffer from both low bearing resolution and potential ambiguities through, for example...

The analysis of a rear-end collision warning/ avoidance (CW/CA) system algorithm will be presented. The system is designed to meet several criteria: 1. System warnings should result in a minimum load on driver attention. 2. Automatic control of the brakes should not interfere with normal driving operation. 3. The system should perform well in a variety of driving conditions. The resulting CA al...

To improve organizational communication, this study identified the primary targets of sexual harassment in Latin America as a point of departure in addressing how managers can focus on strategic communication designed to deter future harassment. Consequently, this study reported the antecedent socio-cultural factors (i.e., marital status, age, education, race and sex) associated with employee t...

Ž . An effective approach to obstacle detection and avoidance for autonomous land vehicle ALV navigation in outdoor road environments using computer vision and image sequence techniques is proposed. To judge whether an object newly appearing in the image of the current cycle taken by the ALV is an obstacle, the object shape boundary is first extracted from the image. After the translation from ...
