Application of a Discontinuous Form of Macroscopic Gazis-Herman-Rothery Model to Steady-State Freeway Traffic Stream Observations
TRANSPORTATION RESEARCH RECORD, 2672(20), 51–62.
Contributors: I. Ahmed n , B. Williams n & M. Samandar n
TL;DR:
Three constraints justified by the Highway Capacity Manual were applied to fit the model so that the fitted parameters have reasonable and physically interpretable values, and two statistical performance measures verify that the proposed model is preferable to the HCM models both in terms of fit alone and when considering the tradeoff between fit and model complexity.

Weigh Station Impact on Truck Travel Time Reliability: Results and Findings from a Field Study and a Simulation Experiment
TRANSPORTATION RESEARCH RECORD, 2672(9), 120–129.
Contributors: M. Samandar n, B. Williams n & I. Ahmed n
TL;DR:
The model results indicate that WIM technology does increase travel time reliability and provides benefits to both trucking companies and enforcement agencies, and it was also found that increases in the proportion of WIM bypass result in increases in routeTravel time reliability.

Effect of Light Duty Vehicle Performance on a Driving Style Metric
TRANSPORTATION RESEARCH RECORD, 2672(25), 67–78.
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.

Simulation of Work Zones with Lane Closures in Proximity of Freeway Interchanges
IEEE INTELLIGENT TRANSPORTATION SYSTEMS MAGAZINE, 10(3), 184–195.
TL;DR:
The paper illustrates how ramp demand affects the share of segment capacity available to mainline traffic to reveal strategies for controlling this demand (via ramp metering for example) in order to maintain a prescribed freeway capacity through the work zone.
