A Comparison of CORSIM and INTEGRATION for the Modeling of Stationary Bottlenecks
(Virginia Tech, 2001-05-09)
Though comparisons of simulation models have been conducted, few investigations have examined in detail the logical differences between models. If the output measures of effectiveness are to be interpreted correctly, it ...
Evaluation of Service Reliability Impacts of Traffic Signal Priority Strategies for Bus Transit
(Virginia Tech, 2002-06-03)
Recent progress in technology has facilitated the design, testing, and deployment of traffic signal priority strategies for transit buses. However, a clear consensus has not emerged regarding the evaluation of these ...
Live Stop-Controlled Intersection Data Collection
(Virginia Center for Transportation Innovation and Research, 2007-12)
This report describes an experimental investigation performed at live intersections to gather infrastructure-based naturalistic driver approach behavior data. This data was collected and analyzed with the goal of understanding ...
Modeling 100-car safety events: a case-based approach for analyzing naturalistic driving data: final report
(Virginia Tech. Virginia Tech Transportation Institute, 2009-09-30)
This study developed an integrated framework for modeling the safety outcomes of naturalistic driving studies and addressed several critical methodological issues. The results indicate a certain level of discrepancy between ...
Phoenix Metropolitan Model Deployment Initiative Evaluation Report
(United States. Federal Highway Administration, 2000-04)
This report presents the evaluation results of the Phoenix, Arizona Metropolitan Model Deployment Initiative (MMDI). The MMDI was a three-year program of the Intelligent Transportation Systems (ITS) Joint Program Office ...
Method for identifying rural, urban, and interstate driving in naturalistic driving data : final report
(Virginia Tech. Virginia Tech Transportation Institute, 2009-03-12)
By employing the functionality of GIS, code was written which allows for an automated process to compare the GPS data recorded in the naturalistic driving data with geographic map data from the U.S. Census Bureau and road ...
Enhanced Night Visibility Series, Volume III: Phase II - Study 1: Visual Performance During Nighttime Driving in Clear Weather
(United States. Federal Highway Administration, 2005-12)
Phase II-- Study 1 was performed as a stepping stone to expand the knowledge of how different vision enhancement systems can affect detection and recognition of different types of objects. The empirical testing for this ...
Wet Night Visibility of Pavement Markings
(Virginia Center for Transportation Innovation and Research, 2004-10)
This report describes an investigation into the performance of pavement markings in wet night conditions. The performance of a typical pavement marking will degrade when it gets wet. This is a result of the flooding of the ...
Reducing fog-related crashes on the Afton and Fancy Gap Mountain sections of I-64 and I-77 in Virginia
(Virginia Center for Transportation Innovation and Research, 2002-10)
The Fancy Gap and Afton Mountain interstates have a long history of fog-related, multivehicle crashes. Because of its earlier involvement in the installation and evaluation of the original Afton Mountain in-pavement fog ...
Development and validation of a luminance camera: final report
(Virginia Tech. Virginia Tech Transportation Institute, 2009-02-11)
Under the sponsorship of the National Surface Transportation Safety Center for Excellence (NSTSCE), an effort was undertaken to develop a system of image capture to analyze luminance data gathered in naturalistic driving research.
