The situational factors associated with youthful driving while intoxicated (DWI) and riding with an impaired driver (RWID) are examined. Data were collected from separate samples of youth who had driven while impaired by alcohol and who had ridden with an alcohol-impaired driver. The purpose of the study was to determine whether there are consistent situational factors associated with DWI and R...

Railway level crossings have the potential to bring motor vehicles and trains into fatal contact. In Australia there are approximately 9,400 public railway level crossings across the country, protected either passively (64%) or by active/automated systems (28%). Passive crossings provide only a stationary sign warning of the possibility of trains crossing. Their message remains constant over ti...

as functional integration has increased in hand-held consumer devices features such as global positioning system (gps) receivers have been embedded in increasingly more devices in recent years. for example, the train positioning system based on gps provides an integrated positioning solution which can be used in many rail applications without a cost intensive infrastructure. the network built i...

In order to give a warning to the drowsy driver, this paper proposes a new Fatigue Driving Detection Algorithm. AdaBoost algorithm is applied to fast detect and track human faces, and the algorithm is implemented in FPGA; differential template-based multi-algorithms are used to localize human eyes and recognize eye states; PERCLOS algorithm is adopted to analyze and determine whether a person i...

but does require sufficient real traffic and action data to capture the underlying relationship between states and actions. Therefore, ANN models estimate actions on the basis of the real state–action mapping of natural behavior. Data from the naturalistic driving database of the Naturalistic Truck Driving Study (NTDS) (1), collected by the Virginia Tech Transportation Institute and Blanco et a...

Alcohol availability has been linked to drunk driving, but research has not examined whether this relationship is the same for first-time and repeat offenses. We examined the relationship between the business hours of alcohol outlets licensed to serve alcohol for on-premises consumption and misdemeanor-level (first offense) and felony-level drunk driving (repeat offense) charges in New York Sta...

This paper is about building robots that get better through use in their particular environment, improving their perceptual abilities. We approach this from a life long learning perspective: we want the robot’s ability to detect objects in its specific operating environment to evolve and improve over time. Our idea, which we call Experience-Based Classification (EBC), builds on the well establi...

Driving simulators have been used to support the development of new vehicle systems for many years. The rise of electric vehicles (EVs) as a means of reducing carbon emissions has lead to the emergence of a number of new design challenges related to the performance of EV components and the flow of power under a variety of circumstances. In this paper we describe the integration of an EV drive t...

Developing feedback systems that can detect the attention level of the driver can play a key role in preventing accidents by alerting the driver about possible hazardous situations. Monitoring driver’s distraction is an important research problem, especially with new forms of technology that are made available to drivers, which can interfere with the primary driving task. An important question ...

Challenges facing fuel cell hybrid vehicles is in implementing a control strategy to find the optimal split of power between the different power sources. This paper proposes a mathematical model of power flow in such vehicles taking into consideration power train losses. Linear programming locates the global optimum indicating the finest synchronization among power units in an attempt to lower ...
