Compared to using connected vehicle data alone, algorithms developed to estimate the positions of unequipped vehicles can result in up to an 8 percent reduction in delay.
Methodology
Four tasks were carried out to achieve the study objectives:
Literature review
The literature was reviewed to determine similar proposed techniques to estimate positions of individual…
