This article introduces a high-level system using belief functions for exchanging and managing imperfect information about events on the road in vehicular ad-hoc networks. The main purpose of this application is to provide the most reliable information for the driver from multiple messages received informing the driver about events on the roads. This system and some variants are tested using a ...

OBJECTIVE To find an association between cognitive-perceptual problems of older drivers and unsafe driving performance during simulated automobile driving in a virtual environment. DESIGN Cross-sectional study. SETTING A driver evaluation clinic in a rehabilitation hospital. PARTICIPANTS Fifty-five drivers aged 65 years or older and 48 drivers in their late twenties to early forties. ME...

OBJECTIVES This prospective longitudinal study aims to determine which simulated driving tasks of a personal computer (PC)-based driving simulator can be used to identify problematic older drivers, using their 3-year driver violation points record as the outcome measure. METHODS A total of 129 urban community-dwelling older drivers volunteered to participate in the study. Using a driving simu...

More US teens die from traffic crashes than from any other cause, with speed and rural roads major contributing factors. This study aimed to validate a high-fidelity simulator to explore these risks in an injury-free environment. Twenty-one newly-licensed 16-year-old males completed simulated and on-the-road drives of the same rural roads. Average free speeds on three road segments showed no sy...

Although task analysis of pedestrian detection can provide us with useful insights into how a driver may behave in emergency situations, the cognitive elements of driver decision-making are less well understood. To assist in the design of future Advanced Driver Assistance Systems, such as Autonomous Emergency Brake systems, it is essential that the cognitive elements of the driving task are bet...

In spring 2002, the Center for Advanced Traffic System Simulation (CATSS), at the University of Central Florida, acquired a sophisticated reconfigurable driving simulator. This driving simulator is capable of supporting research in driving simulation, driver training, traffic engineering and human factors. However, it is crucial to assess the validation of the driving simulator since the credib...

This paper describes on-going research aimed at developing a 3-in-1 integrated traffic-driving-networking simulator (ITDNS) for the design and evaluation of Cyber Transportation Systems (CTS) and Connected Vehicle (CV) applications. This unique simulator allows a human driver to control a subject vehicle in a virtual environment; this vehicle is capable of communicating with other vehicles and ...

This paper presents a pre-trip demand simulator with predictive capabilities and an explicit simulation of the response of travelers to real-time pretrip information. The demand simulator is an extension of dynamic OD estimation models aimed at explicitly capturing the effect of information on demand. This is achieved by explicitly simulating driver behavior in response to both descriptive and ...

The Error Simulator allows for simulating errors during the runtime of a component. This is especially useful, when testing a component in an environment with multiple threads or processes. If resources are shared among threads and processes, race conditions can lead to unexpected behavior during runtime. In some cases, a particular scenario cannot be tested by just having a test driver invokin...

Over the past five years, there has been considerable growth and established value in the practice of modeling automotive software requirements. Much of this growth has been centered on requirements of software associated with the established functional areas of an automobile, such as those associated with powertrain, chassis, body, safety and infotainment. This paper makes a case for modeling ...
