Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang Jan 2019

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are ...


The Impact Of Transportation Network Companies On Public Transit: A Case Study At The San Francisco International Airport, Lianne Renee Sturgeon Jan 2019

The Impact Of Transportation Network Companies On Public Transit: A Case Study At The San Francisco International Airport, Lianne Renee Sturgeon

Scripps Senior Theses

The emergence and rapid growth of Transportation Network Companies (TNCs), such as Uber and Lyft, has challenged the transportation industry by offering a new mode of transportation to consumers. It is imperative that transit agencies and cities understand the effect of TNCs on public transit usage to make informed decisions. This study analyzes the impact of TNCs on Bay Area Rapid Transit (BART) ridership at the San Francisco International Airport (SFO) to measure the effect of TNCs on public transit. Using a fixed effects model to analyze hourly BART and TNC ridership data from 2011 to 2018, these findings suggest ...

Exploring Transit-Based Environmental Injustices In San Gabriel Valley And Greater Los Angeles, Bailey Lai Jan 2019

Exploring Transit-Based Environmental Injustices In San Gabriel Valley And Greater Los Angeles, Bailey Lai

Pomona Senior Theses

This thesis attempts to disentangle the multilayered interactions between Greater Los Angeles’s history, its built environment, and its inequitable treatment of different peoples, focusing on how transportation in surrounding suburban communities like San Gabriel Valley has developed in relation to the inner city of Los Angeles. Greater Los Angeles contains a long, winding trajectory of transit-based environmental injustices, from the indigenous societies being overtaken by the Spanish missions, to the railroads and streetcars boosting the farmlands and urban growth of Los Angeles, leading into the decline of transit and rise of automobile-oriented suburbia. Within the San Gabriel Valley, the ...


Modeling Mixed Freeway Traffic: Human-Driven And Self-Driven Cars, Xianfeng Terry Yang, Zhao Zhang, Zhehao Zhang Dec 2018

Modeling Mixed Freeway Traffic: Human-Driven And Self-Driven Cars, Xianfeng Terry Yang, Zhao Zhang, Zhehao Zhang

TREC Project Briefs

Connected automated vehicles (CAVs) are typically equipped with communication devices (e.g., dedicated short range communications (DSRC)) and on-board sensors (e.g., Radar, Lidar, Camera, etc.). Communication devices would enable the exchange of real-time information between vehicles and infrastructures via vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) channels. Sensors equipped in vehicles are providing various vehicle sensor data (VSD) such as the CAV’s GPS location, speed and moving direction (trajectory). Existing studies have shown the effectiveness of using CAV trajectories as input in many traffic control models.

However, it can be expected that CAVs and human-driven vehicles (HVs) will co-exist on ...

The Universality Of The Human Condition: Theorizing Transportation Inequality Claims By Persons With Disabilities In Canada, 1976-2016, Laverne A. Jacobs Jun 2018

The Universality Of The Human Condition: Theorizing Transportation Inequality Claims By Persons With Disabilities In Canada, 1976-2016, Laverne A. Jacobs

Laverne Jacobs

Transportation is the lifeline that connects persons with disabilities with the community, and facilitates greater opportunities for work, social inclusion and overall independence. Adequate accessible transportation has long been a concern of persons with disabilities, yet there is a dearth of sustained research on the legal and societal implications of transportation inequality for persons with disabilities. This article contributes to the research on both transportation inequality and equality theory by providing an empirical and theoretical analysis of the human rights tribunal decisions on transportation equality in Canada. In doing so, it examines the issues from the perspective of the voices ...

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister

Graduate Student Portfolios

The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2 ...

Bike Lanes, Not Cars: Mobility And The Legal Fight For Future Los Angeles, Ernesto Hernandez-Lopez Feb 2018

Bike Lanes, Not Cars: Mobility And The Legal Fight For Future Los Angeles, Ernesto Hernandez-Lopez

William & Mary Environmental Law and Policy Review

In 2015, the City of Los Angeles adopted the controversial Mobility Plan 2035. The Plan restructures city transportation planning by emphasizing alternatives to cars for the next twenty years. Predictably, bike lanes became its most polemic aspect. The Plan envisions dramatic increases in bike lanes throughout car-obsessed Los Angeles. This bike lane increase was challenged in court, with objectors claiming that eliminating car lanes would increase congestion and compromise air quality. These arguments are ironic, since environmental justifications typically motivate bike projects.

The Mobility Plan illustrates how law supports and challenges bike lane projects. This Article argues that although this ...

The Scott’s Addition neighborhood in Richmond, Virginia has faced growing density and redevelopment as the neighborhood has become an appealing place to live, work, and play. Myers Street sits directly East from most of Scott’s Addition and has historically housed many industrial businesses. The street is rapidly transforming as many commercial/retail businesses are moving into the corridor. Streetscape redevelopment of the corridor will cause a need for complete streets infrastructure allowing the street to be a safe place for all people, urban design to provide visual aesthetics, and sustainable water runoff catchments to help displace stormwater to ...


Environmental Justice Activism Against Freeway Proposals In Contemporary America, Molly Wampler Jan 2018

Environmental Justice Activism Against Freeway Proposals In Contemporary America, Molly Wampler

Summer Research

Transportation infrastructure provides an excellent lens through which to look at environmental justice. There is legislation in place that should prevent or at least draw significant attention to environmental justice, yet new freeways are still being proposed which continue to commit the same environmental injustices as decades past. With grassroots opposition as a primary form of resistance, this paper investigates the tools available to activists, as well as the ones most effective in ensuring success of the movement. I also consider what accounts for the difference in outcomes of resistance movements, why some community movements are successful in stopping a ...

The Tourist Destination From Hell: An Exploration Of The Multi-Jurisdictional Set-Up Of Vista Point Parking Lot, Genna Gores

Scripps Senior Theses

The Golden Gate Bridge, and the surrounding national parks, are one of the most iconic tourist destinations in the world. Although this area is idyllic in many ways, its underlying governmental set-up creates traffic problems on the US-101 highway that angers tourists and commuters alike. One piece of land that exacerbates the increasing congestion on this section of US-101 is the Vista Point parking lot that is just North of the Golden Gate Bridge. This parking lot’s entrance is just off of the Northbound side of US-101, and during summer and holiday weekends cars will queue onto the freeway ...


An Assessment Of The Sharing Economy And Its Policy Solutions Through The Lens Of Sustainability, Chloe An Jan 2018

An Assessment Of The Sharing Economy And Its Policy Solutions Through The Lens Of Sustainability, Chloe An

Pomona Senior Theses

This senior thesis in environmental analysis explores the promise of sustainability of the sharing economy, its shortcomings from this positive potential, and possible policy solutions to help it reach its fullest, positive potential. At its core, the sharing economy enables shared access to goods and services that would otherwise sit in idle or underutilized capacity – popular platforms such as Uber, Lyft, Airbnb, and craigslist all fall within the sharing economy. By enabling affordable and convenient access to goods that would otherwise sit idle, the sharing economy encourages maximal use of a good that already exists rather than seeking out the ...

Center For Population Dynamics Quarterly Brief January 2017: Transportation’S Role In The Economic Restructuring Of Cleveland, Richey Piiparinen, Jim Russell

Richey Piiparinen

Transportation is the vessel for the movement of people. Migration is the actual movement of people. Both transportation and migration are dictated by the economic eras of which they are a part. These economic eras are most simply illustrated by showing the type of work people did across our nation’s history. Nearly 70% of the nation was employed in agriculture in the 1840s. Fast forward to 1930 and employment in mining, manufacturing, and construction—categorized as “industry” employment—surpassed farm work, with industrial jobs peaking in 1960. Then, the era transitioned into a knowledge economy dominated by the proliferation ...

Additionally, growth patterns of ...


The Missouri Student Transfer Program, Howard E. Fields Iii Apr 2017

The Missouri Student Transfer Program, Howard E. Fields Iii

Dissertations

In 1993, the state of Missouri passed the Outstanding Schools Act. This law was created as a means to ensure that “all children will have quality educational opportunities, regardless of where in Missouri they live.” Section 167.131 of this law states that an unaccredited district must pay the tuition and transportation cost for students who attend an accredited school in the same or adjoining district. This portion of the law became known as the Student Transfer Program.

The Riverview Gardens School District (RGSD) was one of three unaccredited school districts in the state of Missouri in 2013. With close ...
