Autonomous Driving (AD) and Advanced Driver Assistance Systems (ADAS) are being vigorously developed for improving traffic safety and transportation efficiency. AD and ADAS need to provide smooth and comfortable driving experiences to drivers and passengers as well as accommodation of other traffic. Individual drivers have different driving styles. This paper proposes a driver-adapted narrow road...
For this study, using Bayesian Network (BN) to graphically express the interrelationship between safety confirmation behaviors for driving scene and driver's internal state, we analyze correlations between characteristic body information (i.e., eye-gaze / face orientation) and operation information (i.e., steering wheel, accelerator, and brake), when switching from "concentrating state"...
At night, accidents are more severe and involve vulnerable people, older people with disabilities, and mothers with children. Increasing the level of illumination in the pedestrian crossing area by optimally dimensioning the associated lighting system leads to the driver being alerted to the presence of a risk area and adapting the speed of movement to avoid any danger. The projected pedestrian lighting...
A novel method for evaluating driver distraction and situation awareness while performing a secondary task using a fuzzy set theory is proposed in this paper. A fuzzy inference engine realization process based on simple matrix operations is described in detail. The drivers' performance is evaluated referring to the vehicle behavior, in particular, the abilities to keep the vehicle in the center of...
High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert...
Recently, the performance evaluation of V2X(Vehicle to Vehicle, Infrastructure, Pedestrian and so on, or namely Vehicle to Everything) Communication System becomes more and more imperative because of the rapid development and urgently-needed deployment of Intelligent Transportation System. 802.11p and LTE-V are the main communication technologies which would be used in V2X system. Performance evaluation...
In order to reduce the traffic accidents caused by fatigue driving, on the basis of analyzing the current fatigue driving detection methods, the fatigue state detection technology based on human eye state detection is studied. Based on the characteristics of skin color, the color space transformation of YCbCr is used to achieve face location to improve the efficiency of image processing. The binary...
This paper represents a non-cooperative trajectory-planning algorithm for vehicles with consideration of drivers' characteristics. The driver-vehicle model considering driver's different characteristics is applied to formulate a vehicle to vehicle (V2V) encountering system. The non-cooperative control algorithm is employed to plan collision-free trajectories for these encountering vehicles with initial...
This paper proposes a method to monitor driver's movement using capacitive electrocardiogram (ECG) sensors. The sensor measures ECG by sensing voltage changes in our body, and voltage changes according to the movement of the body also can be measured by the sensor. The proposed method uses independent component analysis to decompose the signal component related to the body movement in the measured...
Recent research on eco-driving has paid more attention on human driving behavior and vehicle performance, but neglects the impacts imposed by dynamic, discrete and distributive traffic, which may result in partial and limited eco-driving suggestions. This paper presents a multi-factor integration based eco-driving optimization method for vehicles with same driving characteristics. It constructs driving...
Automotive sensors market has valued 19.7 USD billion in 2014 with an expectation of growth up to 30.0 billion in 2020 [1]. Among the different types of sensors for automotive, devices for safety applications result particularly important and appealing. In this scenario, elastomeric polymers represent a low cost, easy-to-use choice that results to be suitable for large-scale application. In this work,...
Real-time head pose recognition is an important function of Advanced Driver Assistance System that need to consider the driver's intention. The majority of early head pose recognition techniques utilize multi-axis sensors or 2D camera images to estimate the head pose in 3D space. When running the head pose recognition systems, the driver has to carry a device with multi-axis sensors or the system...
The world has recently witnessed a great tendency towards rapid urban development. This has been accompanied by an increase in the population and a development in the uses of the land, which changes the reality of transport and increases its problems over time. The city of Mansour suffers from traffic jams in certain parts of its road network due to the increase in population and the shift in the...
With strong wind predicting and warning system setup, train dispatch system structure will change, and will bring change of work process and reliability of the whole system. In order to build a high reliable railway dispatch system, the paper analyzes three railway dispatch system structures and their fuzzy reliability. The first dispatch system with no wind warning system, the second and the third...
In recent years, the road accidents have increased significantly. One of the major reasons for these accidents, as reported is driver fatigue. Due to continuous and longtime driving, the driver gets exhausted and drowsy which may lead to an accident. Therefore, there is a need for a system to measure the fatigue level of driver and alert him when he/she feels drowsy to avoid accidents. Thus, we propose...
Ridesharing is a natural option for increasing the efficiency and availability of transportation, and many factors need to align for ridesharing to successfully meet user needs in the marketplace. This paper explains how some of these issues have been addressed in the creation of GrabShare, a realtime ridesharing service available in an increasing number of Southeast Asian cities including Singapore,...
With increased work load and unsuitable work shifts to survive in the fast paced world of today, people tend to lose sleep. Irregular sleep patterns and lack of sleep leads to drowsiness and fatigue. Drowsiness is perilous for the driver himself and for other drivers on the road and must be avoided for example by noise alerts in the car. This paper describes a method to detect drowsiness after implementing...
The vision of cooperative and automated driving sets new challenges for various industry sectors and research domains. In this context, the telecommunications community is called to provide reliable communication systems for vehicle-to-anything (V2X) communication that combined with sensor-based technologies will improve the performance of automated driving and increase further traffic safety. 3GPP...
Today, driver assistance systems and autonomous vehicles are actively developed and verified in real-world test scenarios. These real-world tests are neither cheap nor sufficient to ensure a reasonably low enough risk of failure. In order to enable efficient and methodical system tests, we propose the use of Virtual Testbeds (VTBs) as a software environment in which "Digital Twins" of real...
The article presents the research results of the existing payment systems on urban passenger transport. The methodology for conducting a comparative analysis of travel payment systems has been proposed by authors. The criteria for their comparative evaluation has been formulated, the weight of each criterion has been determined for both groups of users. The rating of the payment systems has been determined...
