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

Incorporate Emerging Travel Modes In The Regional Strategic Planning Model (Rspm) Tool, Liming Wang, Joseph Broach, Huajie Yang
Incorporate Emerging Travel Modes In The Regional Strategic Planning Model (Rspm) Tool, Liming Wang, Joseph Broach, Huajie Yang
TREC Final Reports
Performance-based planning helps local and state decision makers to understand the potential impacts of policy decisions, supporting cost-effective investments and policy choices that can help achieve policy goals. In addition, it can enable monitoring of progress and facilitate needed adjustments, help them communicate to the public, and assist them with meeting federal regulations and the intent of MAP21. The Regional Strategic Planning Model (RSPM) is a performance-based planning tool first developed by Oregon State DOT (as GreenSTEP) and later adapted for use by other states in the form of the Federal Highway Administration (FHWA) Emissions Reduction Policy Analysis Tool (EERPAT) …

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister
Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister
Graduate Student Portfolios, Professional Papers, and Capstone Projects
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
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 …
Environmental Justice Activism Against Freeway Proposals In Contemporary America, Molly Wampler
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 …
Myers Street Streetscape Plan, Nathan J. Manning
Myers Street Streetscape Plan, Nathan J. Manning
Master of Urban and Regional Planning Capstone Projects
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 name just a …
The Tourist Destination From Hell: An Exploration Of The Multi-Jurisdictional Set-Up Of Vista Point Parking Lot, Genna Gores
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 completely …
An Assessment Of The Sharing Economy And Its Policy Solutions Through The Lens Of Sustainability, Chloe An
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 …
