Methodologies For Estimating Traffic Flow On Freeways Using Probe Vehicle Trajectory Data, Khairul Azfi Anuar

Civil & Environmental Engineering Theses & Dissertations

Probe vehicle data are increasingly becoming the primary source of traffic data. As probe vehicle data become more widespread, it is imperative that methods are developed so that traffic state estimators such as flow, density, and speed can be derived from such data. In this dissertation three different methodologies are proposed for predicting traffic flow or volume on a freeway. All of the proposed methodologies exploit several different traffic flow theories in conjunction with probe vehicle data to predict traffic flow. The first methodology takes advantage of the fundamental diagram or speed-flow relationship. The relationship states that flow can be …

15-12 Analysis Of Walking Facility Performance Guidelines For Individuals With Disabilities, Keith Christensen, Anthony Chen, Mohammad Sadra Sharifi

Transportation Research Center Reports

It is necessary to design and evaluate the effectiveness of walking facilities to accommodate the needs of all pedestrian groups, including individuals with disabilities. The Highway Capacity Manual (HCM) defines walking facility performance using a qualitative measure describing operational conditions, or level of service (LOS). However, how closely pedestrian LOS thresholds correspond to actual conditions are questionable. To overcome the limitations, a controlled large-scaled walking experiment involving individuals with disabilities was conducted at Utah State University (USU). A temporary circuit with the necessary walking facilities was constructed using eight foot self-standing walls. In total, 202 (160 without and 42 with …

14-07 Development Of Decision Support Tools To Assess Pedestrian And Bicycle Safety: Focus On Population, Demographic And Socioeconomic Spectra, Deo Chimba, Abram Musinguzi

Transportation Research Center Reports

Despite the increase of these non-motorized trips, bicyclists and pedestrians remain vulnerable road users that are often over represented in traffic crashes. While the currently used methods that identify hazardous locations serve their purpose well, majority represent a reactive approach that seeks improvement after crashes happen. This research addressed these issues and proposed decision support tools to aid the implementation of bicycle and pedestrian safety strategies. This work developed an access based tool to predict the expected number of crashes at different neighborhood levels. This tool combines the traditional methods such as those provided in the Highway Safety manual to …

Mat-762: Building Sustainable Continuously Reinforced Concrete Pavement Using Gfrp Bars: Case Study-Highway 40 West-Montreal, Canada, Abdoulaye Sanni B., Hamdy M. Mohamed, Denis Thébeau, Brahim Benmokrane

Canadian Society for Civil Engineering

Continuously reinforced concrete pavement designs (CRCP) are premium pavement designs that are often used on heavily-trafficked roadways and urban corridors. Although CRCP typically is an effective, long-lasting pavement design, it can develop performance problems when the aggregate-interlock load transfer at the transverse cracks is degraded. The prevalence of wide cracks in CRCP has frequently been associated with ruptured steel and significant levels of corrosion. Because of that, there has been recent interest in identifying new reinforcing materials that can prevent or minimize corrosion-related issues in CRCP. Glass fibre-reinforced polymer (GFRP) bars are one product being investigated for use in CRCP …

Tra-901: Optimizing The Location Of Road Weather Information Systems (Rwis) Stations – A Sampling Design Optimization Approach, Tae J. Kwon, Liping Fu, Stephanie J. Melles, Max S. Perchanok

Canadian Society for Civil Engineering

This study presents an innovative approach to the design of a road weather information monitoring system (RWIS) that optimally combines spatial data on weather-related road surface conditions with data on traffic volume over a state-wide road network. The optimization method minimizes the spatially averaged ordinary kriging variance of hazardous road surface condition (HRSC) frequencies. Since it is desired that an RWIS should also be located at high traffic demand areas, road class data is implemented in the optimization process. Spatial simulated annealing (SSA) is used to search for the optimal RWIS network design by iteratively examining each possible location and …

Tra-904: Road Mortality Hot Spots Of Turtles: A Three-Year Ministry Of Transportation Study In Brant County, Ontario, Will Van Hemessen, Julie Scott, Tisha Doucette, Kirstie Houston

Canadian Society for Civil Engineering

Road mortality has a significant depressive effect on turtle populations in southern Ontario and mitigation measures to reduce turtle road mortality are therefore increasingly being incorporated into road construction projects in the province. This has included the installation of “ecopassages” beneath roadways which enable turtles and other animals to safely move between habitats. These measures are most effective if they are installed at locations with frequent turtle movement and high road mortality rates. We conducted a detailed multi-seasonal survey of turtle road mortality in order to identify mortality “hot spots” along a 4.85 km stretch of highway in Brant County, …

Tra-905: Encountering Rainbow Mussel, A Species At Risk, During Construction Of A Stormwater Management Facility, Robert Ginson, Courtney Beneteau, Tisha Doucette

Canadian Society for Civil Engineering

Many freshwater mussels in the Ontario-Great Lakes Area are considered Species at Risk (SAR) and these are increasingly influencing planning, implementation, and monitoring of infrastructure projects near watercourses. In 2010, the City of London commissioned an on-line Stormwater Management Facility in the Stoney Creek watershed in the form of an Erosion Control Wetland. Design objectives included: creation of additional water storage in the floodplain, prevent erosion in the downstream watercourse, and reclaim natural heritage features lost during infrastructure development. Erosion and sediment controls were applied during construction; however, storm events in December 2011 washed out a section of bank that …

Tra-910: Connected Vehicle V2i Communication Application To Enhance Driver Awareness At Signalized Intersections, Mostafa Mohammed, Yahui Ke, Jie Gao, Hui Zhang, Karim El-Basyouny, Tony Z. Qiu

Canadian Society for Civil Engineering

This study introduces a Vehicle-To-Infrastructure (V2I) architecture to enhance driver awareness at signalized intersections. The main objectives are to (i) provide a proof-of-concept field experiment on the use of V2I communication architecture at a signalized intersection and (ii) evaluate the impact of V2I communication on improving driver performance while crossing the intersection. The proposed V2I communication application will relay an advisory auditory message to the driver regarding the status of the traffic signal. It is expected that driver behaviour is going to change as a result of the in-vehicle audible message. Consequently, the proposed application will collect additional driver performance …

Tra-912: Barn Swallow (Hirundo Rustica) Nesting Habitat, Use Of Bridges And Culverts And Other Structures, And Implications To Infrastructure Projects In Ontario, Sean Spisani, Matt Bruder

Canadian Society for Civil Engineering

Barn Swallow is a medium-sized song bird that is approximately 15 to 18 cm long, which feeds on flying insects. They are easily recognized by their blue glossy back and upper wings, rusty- orange forehead and throat, brownish underbelly, and their deeply forked tails. In Ontario, they are most common in southern and central Ontario but occur as far north as Hudson Bay (COSSARO 2011). Barn Swallows nest on walls or ledges of barns and on other human-made structures such as bridges, culverts or other buildings (Lepage 2007). Barn Swallow often nest in small colonies of 2 to 59 nests …

Tra-914: Tdm To Promote Sustainable Commuting – An Employer’S Perspective, Sarah Hanson, Kevin Phillips

Canadian Society for Civil Engineering

There is a comprehensive transportation consulting industry across Canada that provides engineering services for highway and roadway design, environmental assessments, traffic engineering, etc. that all contribute to the development of our transportation infrastructure. However, as leaders in transportation planning and engineering, these transportation consultants must also strive to ‘practice what we preach’ in terms of promoting sustainable transportation solutions in our communities and in our daily lives. The purpose of this presentation is to examine the Travel Demand Management (TDM) initiatives that our AECOM Richmond Hill office has implemented to promote more sustainable work related commuting, and to present a …

Tra-919: A Survey-Based Approach To Understanding Resilience Implications Of Disruption To Transit Operation, Jenessa Man, Aarshabh Misra, Siva Srikukenthiran, Amer Shalaby

Canadian Society for Civil Engineering

Recent surge in academic and industry-related interest in transit resilience can be partly attributed to the occurrence and impact of disruptive events like Hurricane Sandy, Hurricane Katrina and the July 2005 London bombings. Such events have served not only to highlight the vulnerabilities of our public transit systems to natural disasters, targeted attacks and, broadly speaking, unexpected conditions, but also to garner interest in resilience-based approaches to mitigate and recover from the damage caused. In spite of recent gains in developing better understanding of transit resilience, substantial gaps remain in establishing a clear relationship between resilience and transit planning. This …

Tra-927: The Evolution Of Reptile Mitigation Measures On Highway 69, Terri Rogers

Canadian Society for Civil Engineering

MTO is actively expanding Highway 69 from a two-lane rural highway to a four-lane controlled access freeway. This is being completed through the eastern Georgian Bay area, some of the most pristine habitat for numerous species at risk reptiles. MTO obtained a permit under the Endangered Species Act for the project, prescribing extensive mitigation measures, including a requirement to prevent snakes and turtles from accessing the highway while still being able to access habitat on both sides.

To fulfill this condition, MTO is constructing one of the most permeable highways in Canada. At this stage, MTO has completed 13 passage …

Tra-928: Fish Barrier Mitigation Of An Oversteepened Culvert Within Saugeen First Nation Reserve, Robert A. Amos, Courtney Beneteau, Tisha Doucette, Dan Green, Kirstie Houston, Adele Mochrie, Valerie Nantais, Dave Penny, Doran Ritchie

Canadian Society for Civil Engineering

A deteriorated concrete box culvert conveying a tributary of the Saugeen River under Highway 21 in Ontario had reached the end of its lifespan and was in need of replacement. The tributary supports a diverse range of coldwater fish species such as Rainbow Trout; however, fish passage, particularly upstream migration, has been cut off since the culvert and highway were constructed over seventy-five years ago. Specifically, fish passage has been hindered by shallow sheet flow along the sixty metre flat bottom, excessive velocities associated with the smooth, seven percent gradient, and a perched barrier at the downstream outlet. A key …

Tra-929: A Standard Lexicon To Measure The Level Of Service Of Public Transportation Services Through Online Transit-Oriented Discussions, Moein Hosseini, Tamer El-Diraby, Amer Shalaby

Canadian Society for Civil Engineering

Public involvement in operation and planning of transit services is becoming a major focus of public transportation agencies. With the growing population and diversification of ideas, distilling knowledge from public opinion to incorporate into decision support systems is a major challenge for transit agencies. The common practice is to collect information from customers via Customer Satisfaction Surveys (CSat). Although such surveys provide useful insight for transit agencies, their design, data collection, and interpretation is expensive and time consuming. Because of the qualitative nature of the questions in these surveys, inconsistency in respondents’ perception of the survey questions is another challenge. …
