A Revealed Preference Methodology to Evaluate Regret Minimization with Challenging Choice Sets: A Wildfire Evacuation Case Study

Regret is often experienced for difficult, important, and accountable choices. Consequently, we hypothesize that random regret minimization (RRM) may better describe evacuation behavior than traditional random utility maximization (RUM). However, in many travel related contexts, such as evacuation departure timing, specifying choice sets can be challenging due to unknown attribute levels and near-endless alternatives, for example. This has implications especially for estimating RRM models, which calculates attribute-level regret via pairwise comparison of attributes across all alternatives...

Authorized Vehicles Only: Police, parking, and pedestrian access in New York City

Moran, Marcel E
2023

Sidewalks and crosswalks serve little purpose for pedestrians if they are routinely obstructed by automobiles. In New York City, local journalists and transportation advocates have drawn attention to this occurring, particularly in certain settings. Specifically, there is consistent photographic evidence that streets surrounding New York Police Department (hereafter, NYPD) offices are replete with cars parked on the sidewalk and within crosswalks. Though clearly problematic for pedestrians and abutting residents and local businesses, this type of parking behavior has not been studied...

Trust and Compassion in Willingness to Share Mobility and Sheltering Resources in Evacuations: A case Study of the 2017 and 2018 California Wildfires

Wong, Stephen D

2020

Advances in the sharing economy – such as transportation network companies (e.g., Lyft, Uber) and home sharing (e.g., Airbnb) – have coincided with the increasing need for evacuation resources. While peer-to-peer sharing under normal circumstances often suffers from trust barriers, disaster literature indicates that trust and compassion often increase following disasters, improving recovery efforts. We hypothesize that trust and compassion could trigger willingness to share transportation and sheltering resources during an evacuation.To test this hypothesis, we distributed a survey to...

New Metrics for Measuring Academic Research Outside the Ivory Tower

Levine, Kendra K.
2019

The need to demonstrate the value of research programs is critical for funding sustainability, particularly in the 21st century where research funding is rarely guaranteed beyond the life of a single project. After the great economic crash of 2008 many research programs have also diversified their funding portfolios, which means cultivating new relationships with funders and potentially different objectives of research projects. Measuring the impact of academic research outside academia is critical to providing a holistic view of a research program, but the methods to do so are still being...

California’s Freeway Service Patrol Program Management: Information System Annual Report Fiscal Year 2004-05

Mauch, Michael
Skabardonis, Alex
2007

The Freeway Service Patrol (FSP) is an incident management program implemented by Caltrans, the California Highway Patrol and local partner agencies to quickly detect and assist disabled vehicles and reduce non-recurring congestion along the freeway during peak commute hours. The first FSP program was piloted in Los Angeles, and was later expanded to other regions by state legislation in 1991. As of June 2005, there were ten participating FSP Programs operating in California, deploying over 315 tow trucks and covering over 1,500 (center-line) miles of congested California freeways.The...

Theory of highway traffic signals

Newell, Gordon F.
1989

This report gives a comprehensive survey of the theory of highway traffic signals including isolated signals, one-way arterials, two-way arterials, and networks, limited however, to the common right angle junctions. The emphasis is on the logistics of control strategies rather than recipes for implementation. It is anticipated, however, that the implementation of some of the strategies described here will give substantial reductions in delays as compared with existing procedures.

Peer-To-Peer (P2P) Carsharing: Understanding Early Markets, Social Dynamics, and Behavioral Impacts

2018

Shared mobility services have now become firmly integrated into urban transportation systems across the globe. Carsharing, bikesharing, ridesourcing or transportation network companies(TNCs), and other systems now offer urban travelers access to transportation services that had long been previously only possible through personal vehicle ownership. Carsharing is arguably the pioneer mode of the sharing economy, given it ushered in a new way of thinking and access to the private automobile in the 20thcentury.Since its North American inception in Montreal in 1994, carsharing has undergone...
