This study aims to determine whether ramp meters increase the capacity of active freeway bottlenecks. The traffic flow characteristics at twenty-seven active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering. A methodology for systematically identifying active freeway bottlenecks in a metropolitan area is proposed, which re...

Automated Meter reading systems are a invaluable technological advancement that can lead to a better standard of living, owing to the fact that metering has become a part and parcel of our mundane lives. It solves many issues of the traditional meter reading system like need for human resources, efficiency, accuracy, delayed work, unavailability of customer during metering visit by employee, et...

A method is presented to divide the total congestion delay in a freeway section into six components: the delay caused by incidents, special events, lane closures, and adverse weather; the potential reduction in delay at bottlenecks that ideal ramp metering can achieve; and the remaining delay, due mainly to excess demand. The fully automated method involves two steps. First, the components of n...

This paper discusses the threat to privacy that smart meters pose and offers solutions that protect user privacy without diminishing the provider’s capabilities to use the data for legitimate purposes. Two use cases are considered: collection of aggregated real-time data by the provider for optimization, and monthly billing of customers. For the first, we present various approaches before propo...

The cell transmission model of a freeway is used to compare four congestion-reducing schemes: (R) ramp control only; (T) one lane is tolled and ramps are uncontrolled; (B) bottlenecks are tolled and ramps are uncontrolled; and (RB) ramps are controlled and bottlenecks are tolled. In the base case, ramps are uncontrolled and there are no tolls. It is found that (T) is inefficient and may leave a...

My PhD research focuses on traffic management in freeway networks subject to random disturbances that compromise link capacities. Such disturbances are responsible for a significant portion of congestion in transportation networks, which leads to enormous economic and environmental losses. My research develops a framework that systematically considers the presence of unreliable capacities in th...

In order to improve Multi-polar magnetic structure’s efficiency. Ansoft Maxwell of electromagnetic field finite element software is utilized to study the effect of different polarity arrangement of magnetic seeding element on the magnetic induction intensity of seeding element end and magnetic field distribution in the seeding air gap. As a result of the different electromagnetic coil current d...

In recent years, more than 50 million advanced (smart) metering infrastructure units have been installed by the U.S electric utilities. Although, smart metering can provide hourly or sub-hourly customer load, it has failed to directly benefit and provide actionable information to consumers and engage them in energy savings. Using nonintrusive load monitoring techniques, the smart metering data ...
