Consistent Vmt Mapping And Modeling In California: How Can We Better Assess The Vmt Impacts Of State And Local Transportation Projects?, Serena E. Alexander, Shams Tanvir, Syed Tanvir Ahmed, Annie Jones

Mineta Transportation Institute

Despite California’s ambitious target to achieve carbon neutrality by 2045, the state is not reducing greenhouse gas (GHG) emissions from personal vehicle travel, and per capita Vehicle Miles Traveled (VMT) and GHG emissions continue to increase. One central challenge of climate planning facing California is the lack of consistent methods to measure the VMT impacts of transportation projects. Using both qualitative and quantitative data, this research answers the question: “What are the advantages and limitations of existing VMT calculators to determine the climate impacts of transportation projects to help meet California’s climate goals?” Research methods included: (1) a quantitative analysis …

An Aggregate Matching And Pick-Up Model For Mobility-On-Demand Services, Xinwei Li, Jintao Ke, Hai Yang, Hai Wang, Yaqian Zhou

Research Collection School Of Computing and Information Systems

This paper presents an Aggregate Matching and Pick-up (AMP) model to delineate the matching and pick-up processes in mobility-on-demand (MoD) service markets by explicitly considering the matching mechanisms in terms of matching intervals and matching radii. With passenger demand rate, vehicle fleet size and matching strategies as inputs, the AMP model can well approximate drivers’ idle time and passengers’ waiting time for matching and pick-up by considering batch matching in a stationary state. Properties of the AMP model are then analyzed, including the relationship between passengers’ waiting time and drivers’ idle time, and their changes with market thickness, which is …

Bike Buses: An Evaluation Of An Emerging Active Transportation To School Intervention, Evan Howington, Nathan Mcneil, John Macarthur

TREC Faculty and Staff Publications

Bike buses are a relatively new form of active transportation to school (ATS) that have primarily emerged in Europe and the United States. A form of coordinated, group bike riding along a defined route to school, bike buses are an outgrowth of Safe Routes to School interventions in North America that seek to reverse the declining rates of walking and biking to school among children. Our initial phase of research included a literature review of social and environmental factors affecting ATS in the contemporary North American context, and two convenience surveys of bike bus coordinators and parent participants. This initial …

Ev Charging At Multifamily Properties: Moving Beyond Barriers, Whit Jamieson, Anna Guida, Connor Herman

PSU Transportation Seminars

Transportation is the top contributor of greenhouse gas emissions in the US and light-duty vehicles are the #1 contributor to transportation emissions. Mass adoption of electric vehicles (EVs) is key in the fight toward a more sustainable future, but there are several factors that have delayed our transition to EVs.

EV charging at home is the most convenient and cost-effective charging option for EV drivers, but people living in multifamily housing face serious barriers to accessing home charging. During this session, we will explore why EV charging at multifamily housing is critical to mass adoption of EVs, barriers to charging …

The Heterogeneous Effects Of Cannabis Dispensaries On Crime: The Importance Of Foot Traffic, Thomas Lebesmuehlbacher, Justin Roush, Rhet A. Smith

Hunt Institute Working Paper Series

This paper pairs exact dispensary locations with city block level crime data to study the impact of medical cannabis dispensaries on crime in the state of Florida from 2016-2019. Leveraging a Florida state law that requires broadly uniform security provisions across dispensaries, we capture important dispensary heterogeneity by incorporating customer volume and local non-dispensary foot traffic with smartphone geopositional data. We use not-yet-operational dispensary locations as a control group and a geo-spatial difference-in-differences framework and find reductions in larceny, vehicle burglary, and motor vehicle theft following the opening of high-volume dispensaries. We fail to find evidence of similar deterrent effects …

Territorialising The Cloud Or Clouding The Territory? Volumetric Vulnerabilities And The Militarised Conjunctures Of Singapore's Smart City-State, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article explores how the volumetric characteristics of cloud computing can create new expressions of territoriality, which in turn can reveal new axes of vulnerability and threat. Whilst recent work in political geography has sought to “locate” the cloud through analyses of data centre geographies and data-driven processes of smart urbanism, we look beyond the material plane and consider the amorphous territorialities of voluminous data instead. As much as these data are acted on by the legal-regulatory mechanics of the state in a bid to territorialise them, so too do these data volumes serve to cloud, and thus obscure, territory. …

Urban Heat And Within-City Residential Sorting, Stefan Borsky, Eric Fesselmeyer, Lennart Vogelsand

Research Collection College of Integrative Studies

This study presents new causal evidence on how urban heat contributes to sorting within a city. We estimate a discrete choice residential sorting model that includes census-tract fixed effects and controls for open space and green coverage to analyze how differences in urban heat at the census-tract level influence the location choices of New York City homeowners given their race, ethnicity, and income. Our results show clear patterns of residential sorting, with whites and high-income households outcompeting other racial/ethnic groups and low-income households for housing in cooler neighborhoods. Our counterfactual exercise, inspired by Cool Neighborhoods NYC, reveals that heat-mitigation policies …

Toward Equitable Micromobility: Lessons From Austin E-Scooter Sharing Program, Shunhua Bai, Junfeng Jiao

Research Collection College of Integrative Studies

This study revealed the inequitable societal impacts of E-scooters on disadvantaged populations. The study conducted a population distribution analysis to compare the use opportunities and space intrusion burdens of E-scooter sharing on four vulnerable population groups in Austin, Texas. Nearly all minority population experienced fewer E-scooter use opportunities. Ten percent of the minority population waited for a disproportionately longer time before a disturbance could be resolved. Ten percent of the low-income population were in a disadvantaged position in high opportunities and moderate burdens. Twenty percent of the physically disabled population faced more moderate-level burdens. The result did not show significant …
