Road Work Ahead: Using Deep Neural Networks To Estimate The Impacts Of Work Zones, Abbas Rashidi, Ali Hassandokht Mashhadi

TREC Project Briefs

Roadside construction - be it a detour, a closed lane, or a slow weave past workers and equipment - work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users. Funded by the National Institute for Transportation and Communities, the latest Small Starts project led by Abbas Rashidi of the University of Utah introduces a robust, deep neural network model for analyzing the automobile traffic impacts of construction zones.

Urban Governance And Electricity Losses: An Exploration Of Spatial Unevenness In Karachi, Pakistan, Ijlal Naqvi, Ate Poorthuis, Anirudh Govind

Research Collection School of Social Sciences

The inadequate supply of electricity in Pakistan disrupts everyday life and hampers industry and business; in this it is an emblematic indicator of the poor quality of urban governance pervasive in much of the Global South. We focus on the governance of Karachi’s electricity distribution system, and its spatial unevenness across this sprawling metropolis of 15 million residents which encompasses huge informal settlements alongside upscale housing and commercial plazas. Using a dataset with granular, neighborhood-level electricity data, we apply spatial and statistical modeling techniques to understand how transmission and distribution losses, i.e., the utility’s ability to bill for the electricity …

Evaluating Mobility Impacts Of Construction Work Zones On Utah Transportation System Using Machine Learning Techniques, Ali Hassandokht Mashhadi, Abbas Rashidi

TREC Final Reports

Construction work zones are inevitable parts of daily operations at roadway systems. They have a significant impact on traffic conditions and the mobility of roadway systems. The traffic impacts of work zones could significantly vary due to several interacting factors such as work zone factors (work zone location and layout, length of the closure, work zone speed, intensity, and daily active hours); traffic factors (percentage of heavy vehicles, highway speed limit, capacity, mobility, flow, density, congestion, and occupancy); road factors (number of total lanes, number of open lanes, and pavement grade and condition); temporal factors (e.g., year, season, month, weekday, …
