Engineering and Environmental Assessment of Foam Glass Lightweight Aggregate for Pavement Application
(University of Waterloo, 2019-04-02)Foam-Glass Lightweight Aggregate (FG-LWA) is an innovative lightweight material based 95% on waste and recycled glass. Several European countries use this type of material in the pavement structure and mainly as lightweight ... -
An Enhanced Mechanistic Analysis Framework for Designing Resilient Airfield Pavements
(University of Waterloo, 2023-01-05)Changes in climatic conditions can directly impact pavement performance. With alarming temperature records and the increased frequency of extreme weather events, Canadian infrastructure could be at risk if adaptation ... -
Enhanced Traffic Signal Operation using Connected Vehicle Data
(University of Waterloo, 2017-08-29)As traffic on urban road network increases, congestion and delays are becoming more severe. At grade intersections form capacity bottlenecks in urban road networks because at these locations, capacity must be shared by ... -
Enhanced Transit Ridership Forecasting Using Automatic Passenger Counting Data
(University of Waterloo, 2017-04-07)Recent emphasis on sustainable development has carried over into the transportation sector, given the impacts of transportation behavior on environment and equity. Transit is widely recognized as a viable option supporting ... -
Enhancement of Modeling Phased Anaerobic Digestion Systems through Investigation of Their Microbial Ecology and Biological Activity
(University of Waterloo, 2012-01-25)Anaerobic digestion (AD) is widely used in wastewater treatment plants for stabilisation of primary and waste activated sludges. Increasingly energy prices as well as stringent environmental and public health regulations ... -
Enhancing Real-Time Data Acquisition from Embedded Road Structural Health Monitoring Systems
(University of Waterloo, 2024-04-23)Canada's economy heavily relies on its roadways, yet managing pavement assets faces challenges due to past infrastructure spending cuts. Addressing this, a pavement management system (PMS) is essential for efficient resource ... -
Enriched mixed finite element models for dynamic analysis of continuous and fractured porous media
(Elsevier, 2019-01-01)Enriched Finite Element Models are presented to more accurately investigate the transient and wave propagation responses of continuous and fractured porous media based on mixture theory. Firstly, the Generalized Finite ... -
Estimates of gridded relative changes in 24-h extreme rainfall intensities based on pooled frequency analysis
(Elsevier, 2019-10)The potential effect of climate change needs to be considered in urban infrastructure design and risk assessment to improve reliability. The present study proposes a methodology for obtaining grid-scale relative changes ... -
Estimating Average Annual Daily Pedestrian Volumes at Intersections based on Turning Movement Counts
(University of Waterloo, 2021-12-07)There is a focus on increasing the use of active transportation and, consequently, a need to have pedestrian traffic volumes such as Annual Average Daily Pedestrian Traffic (AADPT) for infrastructure planning and safety ... -
Estimating Bus Delay at Signalized Intersections from Archived AVL/APC Data
(University of Waterloo, 2012-04-09)The travel times of public transit systems that operate on mixed use right-of-ways are often dictated by the delays experienced at signalized intersections. When these delays become large and/or highly variable, transit ... -
Estimating Effectiveness of Countermeasures Based on Multiple Sources: Application to Highway-Railway Grade Crossings
(University of Waterloo, 2007-03-13)To provide an adequate level of safety at grade crossings, Transport Canada has allocated several millions annually to prevent collisions at grade crossings through the implementation of countermeasures, such as train-actuated ... -
Estimating Intersection Annual Average Daily Bicycle Traffic from 8-hour Turning Movement Counts
(University of Waterloo, 2021-09-23)This thesis outlines a set of procedures for estimating annual average daily bicycle traffic (AADB) from one day, 8-hour turning movement counts (TMCs). Factoring methods for annualizing short duration counts have been ... -
Estimation and Occurrence of Select Antimicrobials in the Grand River Watershed
(University of Waterloo, 2015-01-09)Antimicrobials are pharmaceutically active compounds that destroy or inhibit the growth of bacteria, fungi, protozoa, or viruses. This diverse group of compounds, used in both humans and livestock, are increasingly being ... -
Estimation of Pile Capacity by Optimizing Dynamic Pile Driving Formulae
(University of Waterloo, 2012-04-26)Piles have been used since prehistoric times in areas with weak subsurface conditions either to reinforce existing ground, create new ground for habitation or trade, and support bridges and buildings. Originally piles were ... -
Estimation of Stochastic Degradation Models Using Uncertain Inspection Data
(University of Waterloo, 2012-05-18)Degradation of components and structures is a major threat to the safety and reliability of large engineering systems, such as the railway networks or the nuclear power plants. Periodic inspection and maintenance are thus ... -
