Fast Track: Allowing Bikes To Participate In A Smart-Transportation System, Stephen Fickas, Marc Schlossberg

TREC Final Reports

This project focuses on a mode of transportation that is currently left out of V2X (vehicle-to-everything) conversations: bicycling. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to give bicyclists the same technology appearing on modern vehicles: Green Light Optimized Speed Advisory (GLOSA). GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a “green wave” (i.e., not being forced to stop as they travel through the corridor). This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists on a …

Evaluation Of Bus/Bicycle Andbus/Right-Turn Traffic Delays And Conflicts, Miguel A. Figliozzi, Katherine Keeling, Travis Glick

TREC Final Reports

This research evaluates conflicts and delays caused by interactions between buses, bicycles, and right-turningvehicles. Two concerns caused by these overlapping bus, bicycle, and automobile facilities are analyzed; the firstconcern is the number of bus-bicycle conflicts (as a proxy for safety) and the second concern is bus delay. Video datawas collected and analyzed to quantify conflicts, travel time, and delay. For every bus passing through the study site,the mixed-traffic scenario that the bus incurs was categorized as one of 72 different combinations of bus, bicycle, andautomobile interactions. Video count data was weighted according to seasonal, weekly, and hourly bicycle volumedata to …

Biking And Walking Quality Counts: Using “Bikeped Portal” Counts To Developdata Quality Checks, Nathan Mcneil, Kristin Tufte

TREC Final Reports

Cycling and walking are sustainable modes of transportation which improve community livability, but these modes have not been studied with the quantitative rigor applied to motor vehicle travel. This work aims to change that by improving bicycle and pedestrian traffic monitoring data quality, including how erroneous data can most accurately and efficiently be identified through automated processes. The research approach analyzes continuous bicycle and pedestrian count data stored in BikePed Portal, a data archive of bicycle and pedestrian count data. A primary goal of the project is to explore tests that could help to identify aberrant and/or erroneous data. A …

Strategic Implications For The United States Of The Belt And Road Initiative In Africa, Alec Monnie

Independent Study Project (ISP) Collection

The belt and road initiative is one of the most significant developments of the twenty-first century, which the United States will need to learn to adapt to. Much of the academic literature regarding the belt and road initiative mentions that Africa is a significant participant in this policy development, but fail to elaborate as to why that is, or what the implications for this are for the United States. This article expands upon the strategic significance of the African continent, and explains the implications thereof for the United States and China. This article argues that the belt and road initiative …

Barriers And Opportunities To Electric Vehicle Development In Nepal, Allyson Krupa

Independent Study Project (ISP) Collection

As the global carbon dioxide level reaches its highest point in human history (407.4 parts per million), energy systems must transition from fossil fuel to renewable-powered sources. Since the transportation sector contributes nearly one-third of global greenhouse gas (GHG) emissions, electric mobility offers a significant opportunity to reduce GHG emissions. Globally, there has been a rise in demand for electric vehicles. In Nepal, a clean energy transition within the context of rising urbanization and air pollution is imperative for quality of life, socio-economic development, and broadly climate change mitigation/adaptation. Furthermore, Nepal’s vast hydropower potential may increase energy independence and provide …

Inferring Accurate Bus Trajectories From Noisy Estimated Arrival Time Records, Lakmal Meegahapola, Noel Athaide, Kasthuri Jayarajah, Shili Xiang, Archan Misra

Research Collection School Of Computing and Information Systems

Urban commuting data has long been a vital source of understanding population mobility behaviour and has been widely adopted for various applications such as transport infrastructure planning and urban anomaly detection. While individual-specific transaction records (such as smart card (tap-in, tap-out) data or taxi trip records) hold a wealth of information, these are often private data available only to the service provider (e.g., taxicab operator). In this work, we explore the utility in harnessing publicly available, albeit noisy, transportation datasets, such as noisy “Estimated Time of Arrival" (ETA) records (commonly available to commuters through transit Apps or electronic signages). We …

The Effects Of Vehicle Automation Level And Warning Type On Responses To Vehicle Hacking, Wyatt D. Mcmanus

Psychology Theses & Dissertations

Modern surface transportation vehicles often include different levels of automation. Higher automation levels have the potential to impact surface transportation in unforeseen ways. For example, connected vehicles with higher levels of automation are at a higher risk for hacking attempts, because automated driving assistance systems often rely on on board sensors and internet connectivity. As the automation level of vehicle control rises, it is necessary to examine the effect of different levels of automation have on the driver-vehicle interactions. In addition, auditory warnings have been shown to effectively attract a driver’s attention while performing a driving task, which is often …

Evaluating Alternative Measures Of Bicycling Level Of Traffic Stress Using Crowdsourced Route Satisfaction Data, Chester Harvey, Kevin Fang, Daniel A. Rodriguez

Mineta Transportation Institute

Approaches for evaluating the quality of bicycling have become increasingly important for planning bicycle infrastructure improvements. Mekuria, Furth, and Nixon’s (2012) “Level of Traffic Stress” (LTS) approach, which requires minimal data inputs and produces a simple and intuitive output, has emerged as a widely-used framework for identifying streets that are “low-stress” for cyclists. The LTS framework is based on a hierarchy of characteristics, largely related to traffic speed and roadway layout, that are presumed to cause higher or lower levels of stress. Despite the apparent simplicity of LTS, several key challenges emerge from its application. Firstly, multiple LTS classification methods …

How Technology Can Affect The Demand For Bicycle Transportation: The State Of Technology And Projected Applications Of Connected Bicycles, John Macarthur, Michael Harpool, Daniel Scheppke

TREC Final Reports

The term “connected vehicle (CV)” refers to vehicles equipped with devices, which enable wireless communication betweeninternal and external entities, supporting vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-everything (V2X)communications. The widespread deployment of CVs will address a range of transportation challenges related to safety, mobility,and sustainability. Recent research efforts on connected bicycles have focused on the uses and limitations of the state-of-the-arttechnologies, safety implications, the reliability of various communication modes, and consumer adoption. Existing researchfocuses on either technologies that utilize data received from sensors and the internet to govern devices attached to the bicycle(situational sensing) or two-way communication.

The Impact Of Pedestrian Crossing Flags On Driver Yielding Behavior In Las Vegas, Nv, Sheila Clark, Courtney Coughenour, Kelly Baumgarner, Hanns De La Fuente-Mella, Chantel Reynolds, James Abelar

Environmental & Occupational Health Faculty Presentations

Walking is the most affordable, accessible, and environmentally friendly method of transportation. However, the risk of pedestrian injury or death from motor vehicle crashes is significant, particularly in sprawling metropolitan areas. The purpose of this study was to examine the effect of pedestrian crossing flags (PCFs) on driver yielding behaviors. Participants crossed a marked, midblock crosswalk on a multilane road in Las Vegas, Nevada, with and without PCFs, to determine if there were differences in driver yielding behaviors (n = 160 crossings). Trained observers recorded (1) the number of vehicles that passed in the nearest lane without yielding while the …
