AADT Estimation Models and Analytical Comparison of Pedestrian Safety Risk Evaluation Methods for Signalized Intersections
(University of Waterloo, 2021-01-13)Pedestrian road safety is a priority for Canadian municipalities due to the particularly large social and economic impact that pedestrian-vehicle collisions can have on society. There is a constant need to improve roads ... -
Acceptance Criteria for Ultrasonic Impact Treatment of Highway Steel Bridges
(University of Waterloo, 2012-08-30)The need for rehabilitation of bridges has become a critical challenge due to aging and an increase in traffic loads. Many of these bridges are exceeding their design fatigue life. Since many of these bridges are structurally ... -
Acquiring Multimodal Disaggregate Travel Behavior Data Using Smart Phones
(University of Waterloo, 2013-01-25)Despite the significant advances that have been made in traffic sensor technologies, there are only a few systems that provide measurements at the trip level and fewer yet that can do so for all travel modes. On the other ... -
Active Retrofit of Shear Critical RC Components Using Self-Prestressing Iron-Based Shape Memory Alloys
(University of Waterloo, 2023-09-26)With growing traffic demands and structural degradation accelerated by climate change, there is a critical need for continued advancement of concrete repair and strengthening technologies to enable extended bridge service ... -
Activity Analysis for Continuous Productivity Improvement in Construction
(University of Waterloo, 2010-08-30)In the construction industry, onsite labour is one of the most variable and costly factors which affect project profits. Due to the variable nature of construction labour and its correlation with profits, construction ... -
Adaptable Three Dimensional System for Building Inspection Management
(University of Waterloo, 2012-08-30)Sustaining the safety and operability of civil infrastructure assets, including buildings, is a complex undertaking that requires a perpetual cycle involving inspection, and further decisions for renewal fund allocation. ... -
The Adaption of a Rapid Screening Test to Rank the Corrosion Behaviour of Stainless Steel Reinforcing Bars in Concrete
(University of Waterloo, 2018-08-21)The costs associated with aging reinforced concrete infrastructure in Ontario continue to rise as highway infrastructure, such as bridges, continuously deteriorate. The use of de-icing salts on these bridges in the winter ... -
Addressing Uncertainty in Health Impacts of Air Pollution under Climate Change Mitigation
(University of Waterloo, 2022-01-18)Simulations to evaluate climate policy take a lot of time, but little evidence exists to say how long is enough, especially for policy impacts related to air pollution. Air pollution and climate change are the two leading ... -
Advanced Traffic Signal Control Using Bluetooth Detectors
(University of Waterloo, 2018-03-14)Traditionally signal timing plans are developed for expected traffic demands at an intersection. This approach generally offers the best operation for typical conditions. However, when variation in the traffic demand occurs, ... -
Advanced Water Treatment Strategies for the Removal of Natural and Synthetic Organic Contaminants
(University of Waterloo, 2014-01-24)Prior to full-scale implementation of process modifications at the Brantford WTP, a pilot-scale treatability study was conducted to investigate intermediate ozonation/AOP and to determine the most suitable granular media ... -
Advances in River Bedload Tracking Technology: Self-righting Radio Frequency Identification Tracers and an In-stream Automated Station
(University of Waterloo, 2018-09-25)Understanding of bedload transport rates in natural streams has been an area of focus for researchers for decades. Recently, researchers have begun to use Radio Frequency Identification (RFID) technology to track individual ... -
Ammonia Removal and Recovery from Wastewater Using Natural Zeolite: An Integrated System for Regeneration by Air Stripping Followed Ion Exchange
(University of Waterloo, 2014-01-23)This study revealed that ammonium ion exchange of natural zeolite could be a feasible method of nitrogen removal and recovery from permeate from anaerobic membrane bioreactors (AnMBRs). NaCl concentrations optimized for ... -
Anaerobic Biodegradation of Petroleum Hydrocarbons in Powdered Activated Carbon Groundwater Systems: A Modelling Investigation
(University of Waterloo, 2022-09-19)Subsurface contamination by petroleum hydrocarbons (PHCs) is a widespread issue resulting from oil and gas production, distribution, and use. As a result of improved injection methods and particulate materials, injected ... -
ANALYSING ATMOSPHERIC IMPACTS OF REGIONAL TRUCK EMISSIONS USING AN INTEGRATED MODELLING APPROACH
(University of Waterloo, 2018-10-19)Transportation technology is providing new ways to mitigate multipollutant emissions co-emitted from on-road sources. Zero-emission vehicles (ZEV) are more common in passenger vehicles and other light-duty vehicles; however, ... -
Analysis and Design of Link Slabs in Jointless Bridges With Fibre-Reinforced Concrete
(University of Waterloo, 2014-08-29)Many transportation agencies in Canada and the United States have explored alternatives to expansion joints in bridges due to high maintenance costs and poor joint durability. One of the alternatives is the use of link ... -
Analysis of a Construction Small-Projects Rework Reduction Program for a Capital Facility
(University of Waterloo, 2010-01-12)Reducing field rework is widely regarded as an effective way of improving construction performance in terms of productivity, cost, schedule, quality, and safety. While existing rework reduction programs and much literature ... -
