Abstract

Traffic congestion, the main constituent of vehicular extrinsic flow resistance, has been an important factor in the design of routing algorithms. There are important intrinsic factors that can also aid these algorithms. This study proposes a new vehicular intrinsic flow resistance metric referred to as sinuousness. To obtain this metric several scenarios are designed. Each scenario has a unique topology with varying amount of curves, curve-radii lengths, total path lengths, and other features. Simulated vehicles flow through these scenarios and velocity data is gathered. Simulations show that the velocity, and hence the sinuousness, depends on several street aspects, such as distance between curves, curve radii, and aggregated arc circumference. A sinuousness expression is derived. Results show that the proposed metric of sinuousness is proportional and in agreement with the inverse of the average velocity of the vehicles.

Biography

Claudio Estevez received his B.S. degree in electrical and computer engineering from the University of Puerto Rico, Mayaguez, PR, USA, 2001; his M.S. degree in electrical and computer engineering with a minor in optical engineering from the University of Alabama in Huntsville, Huntsville, AL, USA, 2003; and his Ph.D. degree in electrical and computer engineering and with a minor in computer science from the Georgia Institute of Technology, Atlanta, GA, USA, 2010. In 2011, he was hired as an assistant professor by the electrical engineering department at Universidad de Chile. In 2012, he obtained a [Chilean] national research grant (FONDECYT) to study MAC protocols in WPAN using 60 GHz. In the same year he was appointed coordinator of the Communication Networks M.Eng. Program. In 2013, he obtained a [Chilean] national research grant (FONDEF) to study remote polysomnographic monitoring. His research interests include: Connection-oriented transport protocols, network fairness study, MAC-layer protocols in WPAN, 60-GHz WPAN applications, vehicle routing systems, cloud computing with data mining/warehousing, wireless body area networks, remote healthcare.
