Temporal stability of freeway macroscopic traffic stream models

In Transportation Research Record (pp. 131–140).

By: C. Liu*, B. Williams n  & N. Rouphail  n

Contributors: C. Liu*, B. Williams n  & N. Rouphail  n

TL;DR: A method to investigate the issue of temporal stability of freeway macroscopic traffic stream models rigorously with 15 years of traffic data from the London Orbital Motorway is presented and implemented and parameters were found to be relatively stable over time and did not exhibit statistically significant seasonal correlation.

2012 journal article

Development and evaluation of a constrained optimization model for traffic signal plan transition

Transportation Research Part C: Emerging Technologies, 20(1), 185–198.

By: J. Lee * & B. Williams n 

Contributors: J. Lee * & B. Williams n 

author keywords: Traffic control; Signal plan transition; Control optimization; Genetic algorithms
TL;DR: A non-linear mathematical model is presented that provides constrained delay minimization through incremental and simultaneous adjustments in offset and cycle length during plan transitions that showed measurable improvement in delay performance under a broad range of traffic and geometric conditions.

Generating Emissions Information for Route Selection: Experimental Monitoring and Routes Characterization

Journal of Intelligent Transportation Systems, 17(1), 3–17.

By: J. Bandeira *, T. Almeida*, A. Khattak *, N. Rouphail* & M. Coelho *

author keywords: Driving Behavior; Emissions; Route Choice; Vehicle Specific Power (VSP)
TL;DR: It was found that the choice of a route can substantially affect emission rates of the analysed pollutants and that smoother driving styles can also result in considerable emissions reduction, which has implications for future investment and policy decisions regarding eco routing strategies.
