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 ... -
Adaptive Traffic Signal Optimization Using Bluetooth Data
(University of Waterloo, 2017-10-23)Traffic congestion continues to increase in urban centers causing significant economic, environmental, and social impacts. However, as urban areas become more densely developed, opportunities to build more roadways decline ... -
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, ... -
Automatic Transit Schedule Updating Using AVL/APC System
(University of Waterloo, 2018-09-11)Observing and fixing transit vehicle’s schedule adherence problems have always been one of the main priorities of a transit agency, and different approaches have been developed over time to help reflect transit vehicle’s ... -
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 ... -
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 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 ... -
Examining the effects of autonomous vehicle ride sharing services on fixed-route public transit
(University of Waterloo, 2020-05-14)With the increased development of new transportation technologies such as autonomous vehicles and ridesharing fleet services comes the possibility of a new mode of transportation: autonomous vehicle ridesharing services ... -
Improving Predictive Models for Road Safety Screening: Cost-Benefit Data Analytics and Deep Generative Models
(University of Waterloo, 2023-04-17)The process of identifying the sites (e.g., road segments, intersections) within a road network that are most in need of detailed safety audits and interventions with the most potential for improvement is known as road ... -
Real Time Prediction of Traffic Speed and Travel Time Characteristics on Freeways
(University of Waterloo, 2017-01-20)Travel time is one of the important transportation performance measures, and represents the quality of service for most of the facilities. In other words, one of the essential goals of any traffic treatment is to reduce ... -
Short-Term Travel Time Prediction on Freeways
(University of Waterloo, 2019-05-30)Short-term travel time prediction supports the implementation of proactive traffic management and control strategies to alleviate if not prevent congestion and enable rational route choices and traffic mode selections to ... -
Using Microsimulation to Estimate the Impact of Transportation Improvements and Operational Policy Changes on Travel Time Reliability
(University of Waterloo, 2017-01-16)Traditionally, traffic engineers have designed roadway networks and operational strategies to manage congestion and minimize delays during the peak demand period for some “average” or “typical” day. However, increasingly, ...
