Characterizing Lane Changes via Digitized Infrastructure and Low-Cost GPS

TRANSPORTATION RESEARCH RECORD, 2673(8), 298–309.

By: I. Ahmed n , A. Karr *, N. Rouphail n , G. Chun n & S. Tanvir n

Contributors: I. Ahmed n , A. Karr *, N. Rouphail n , G. Chun n & S. Tanvir n

TL;DR: Analysis of naturalistic trajectory data revealed that ramp-to-freeway trips had the highest number of discretionary lane changes in excess of 1 lane change/vehicle, and excessive lane change rates were highest between the two middle freeway lanes. (via Semantic Scholar)

2019 journal article

Development and analysis of eco-driving metrics for naturalistic instrumented vehicles

JOURNAL OF INTELLIGENT TRANSPORTATION SYSTEMS, 25(3), 235–248.

By: S. Tanvir n, R. Chase n & N. Roupahil n

author keywords: Eco-driving; eco-driving evaluation; eco-driving metrics; driving behavior; energy; fuel efficiency; incentives
TL;DR: Two metrics for eco-driving metrics for instrumented vehicles in a longitudinal study environment developed passed the test of consistency so that, at the driver level, both revealed no temporal trend in the scores from month to month across a period of 2 years. (via Semantic Scholar)

Characteristics and Temporal Stability of Recurring Bottlenecks

TRANSPORTATION RESEARCH RECORD, 2672(42), 235–246.

By: I. Ahmed n , N. Rouphail n  & S. Tanvir n

Contributors: I. Ahmed n , N. Rouphail n  & S. Tanvir n

TL;DR: A systematic framework is developed for tracking and archiving the spatiotemporal changes in the recurring bottlenecks and the influence of a long-term work zone in the area and the effect of the rapid growth in traffic demand are revealed. (via Semantic Scholar)

Effect of Light Duty Vehicle Performance on a Driving Style Metric

TRANSPORTATION RESEARCH RECORD, 2672(25), 67–78.

By: S. Tanvir n, H. Frey  n & N. Rouphail n 

Contributors: S. Tanvir n, H. Frey  n & N. Rouphail n 

TL;DR: Findings from this study imply that the choice of vehicle does not significantly alter the natural driving style of a driver, and develops a metric for driving style termed “envelope deviation,” which is a distribution of gaps between microscale activity (1 Hz) and fleet average envelope.
