Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: ATIS Function Transitions
(United States. Federal Highway Administration, 1999-12)
The objective of the first experiment reported below was to measure the cognitive demands associated with transitioning across Advanced Traveler Information System (ATIS) functions. This required the development of both ...
Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: Literature Review
(United States. Federal Highway Administration, 1996-11)
The purpose of Task A was to conduct a literature review of human factors-applicable articles associated with Advanced Traveler Information Systems (ATIS) and ATIS-related commercial vehicle operations (CVO) systems. ...
On-line Traffic Signalization using Robust Feedback Control
(Virginia Tech, 1997-12-18)
The traffic signal affects the life of virtually everyone every day. The effectiveness of signal systems can reduce the incidence <BR>of delays, stops, fuel consumption, emission of pollutants, and accidents. The problems ...
Application of Magnetorheological Dampers for Vehicle Seat Suspensions
(Virginia Tech, 1997-12-03)
This study evaluates and provides solutions to the problem of poor subjective feel of seat suspensions that employ magnetorheological (MR) dampers and skyhook control. An Isringhausen seat suspension that had been modified ...
A Method to Enhance the Performance of Synthetic Origin-Destination (O-D) Trip Table Estimation Models
(Virginia Center for Transportation Innovation and Research, 1998-01)
The conventional methods of determining origin-destination (O-D) trip tables involve elaborate surveys, e.g., home interviews, that require considerable time, staff, and funds. To overcome this drawback, a number of ...
Development of Human Factors Guidelines for ATIS and CVO Identify Strengths and Weaknesses of Alternative Information Display Formats
(United States. Federal Highway Administration, 1993-10)
This report is one of a series produced as part of a contract designed to develop precise, detailed, human factors design guidelines for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO). ...
Effects of In-Vehicle Information Systems (IVIS) Tasks on the Information Processing Demands of a Commercial Vehicle Operations (CVO) Driver
(Virginia Tech, 1999-12-10)
This study was performed with two main goals in mind. The first goal was to understand and predict "red-lines" and "yellow-lines" in terms of what the CVO driver can process without hindering the primary task of driving. ...
TravTek Evaluation Task C3 - Camera Car Study
(United States. Federal Highway Administration, 1995-06)
The goal of the TravTek Camera Car Study was to furnish a detailed evaluation of driving and navigation performance, system usability, and safety for the TravTek system. To achieve this goal, an instrumented "camera car" ...
Review and evaluation of models that produce trip tables from ground counts
(Virginia Center for Transportation Innovation and Research, 1996-02)
This research effort was motivated by the desires of planning agencies to seek alternative methods of deriving current or base year Origin-Destination (O-D) trip tables without adopting conventional O-D surveys that are ...
Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: Display Channels
(United States. Federal Highway Administration, 1999-12)
Three experiments were conducted in a driving simulator to evaluate effects of in-vehicle message modality and message format on comprehension and memory for younger and older drivers. Visual icons and text messages were ...
