The following individuals read and discussed the thesis submitted by student Brian Richard Portugais, and they evaluated his presentation and response to questions during the final oral examination. They found that the student passed the final oral examination. iv DEDICATION " Forgetting what is behind and straining toward what is ahead, I press on toward the goal… " (Philippians 3:13-14) The w...

This paper investigates the problem of regulating in real time a linear dynamical system to solution trajectory time-varying constrained convex optimization problem. The proposed feedback controller is based on an adaptation saddle-flow dynamics, modified take into account projections constraint sets and output-feedback from plant. We derive sufficient conditions tunable parameters (inherently ...

A safe headway to the lead vehicle is important reduce conflicts with merging vehicles from highway on-ramps. Previous research has outlined advantage of gap metering strategies yield sufficient space and improve capacity during peak hours. However, prevailing systems fail indicate minimum required leave it drivers’ judgment adjust their headway. This paper proposes a new Active Gap Metering (A...

This paper simulates, analyzes, and compares, for two case studies (one synthetic freeway one real-life freeway), the behavior of Logic-Based Traffic Flow Control (LB-TFC), an integrated control strategy Ramp Metering (RM) installations Variable Speed Limits (VSLs) that was proposed derivated in first part work (‘Part 1: Controller’). For study, which presented work, performance LB-TFC is compa...

Currently most optimization methods for urban transport networks (i) are suited for networks with simplified dynamics that are far from real-sized networks or (ii) apply decentralized control, which is not appropriate for heterogeneously loaded networks or (iii) investigate good-quality solutions through micro-simulation models and scenario analysis, which make the problem intractable in real t...

have used either revealed preference or stated preference data and various forms of logit choice models (e.g., multinomial, nested, and mixed random effect) to identify marginal rates of substitution between travel time and the price of a trip. It is intuitive that the value of travel time is not constant in all situations. Previous studies suggest it varies by assorted trip characteristics inc...
