Using Optimization Methods For Solving Problems In Sustainable Urban Mobility And Conservation Planning, Zulqarnain Haider Jul 2020

Using Optimization Methods For Solving Problems In Sustainable Urban Mobility And Conservation Planning, Zulqarnain Haider

USF Tampa Graduate Theses and Dissertations

This dissertation considers three separate optimization problems related to sustainable urban and environmental systems. The first problem relates to the nightly relocation and recharging operations for Free-floating electric vehicle sharing (FFEVS) systems. Such operations involve a crew of drivers to move the shared electric vehicles (EVs), and a fleet of shuttles to transport those drivers. Mixed integer programs are used to model the relocation and recharging operations. Two approaches are devised: sequential and synchronized approaches. In the sequential approach, the movement of EVs is first decided, then the routing of shuttles and drivers is determined. In the synchronized approach, all …

Harmonizing Climate Change Mitigation And Adaptation In Transportation And Land-Use Planning In California Cities, Serena E. Alexander, Asha Weinstein Agrawal, Ashley M. Hooper, Michael R. Boswell

Mineta Transportation Institute

Abstract: Recent extreme weather events in California—wildfires, drought, and flooding—make abundantly clear the need to plan effective responses to both the causes and the consequences of climate change. A central challenge for climate planning efforts has been identifying transportation and land-use (TLU) strategies that simultaneously reduce greenhouse gas emissions (“mitigation”) and adapt communities so that they will be less affected by the adverse impacts of climate change (“adaptation”). Sets of policies that collectively address both mitigation and adaptation are known as “integrated actions.” This study explores municipal climate planning in California to determine whether cities incorporate integrated actions into their …

An Evaluation Of The Impact Of Leading Pedestrian Interval Signals In Nyc, Jeremy J. Sze May 2019

An Evaluation Of The Impact Of Leading Pedestrian Interval Signals In Nyc, Jeremy J. Sze

Theses and Dissertations

I evaluated the impact of the phased introduction of Leading Pedestrian Interval Signals (LPIs) on collision and injury outcomes at 12,987 signalized traffic intersections in New York City over the course of 25 quarters from 2012 to 2018. An intersection is treated when a LPIs is installed to give pedestrians lead time to cross the street before vehicles are allowed to move. Outcomes from NYPD’s Motor Vehicle Collisions data were matched to signalized intersections. I hypothesize that LPIs would reduce collisions and reduce injuries for pedestrians at intersections. A difference in difference fixed effects panel regression was used to identify …

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 …

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 suburban …


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 transportation network …

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 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 …
