Recent technological improvements have greatly expanded the sharing economy (e.g., Airbnb, Lyft, and Uber), coinciding with growing need for transportation and sheltering resources in evacuations. To understand influencers on sharing willingness in evacuations, we employed a multi-modeling approach across four sharing scenarios using three model types: 1) four binary logit models that capture each scenario separately; 2) a multi-choice latent class choice model (LCCM) that jointly estimates multiple scenarios via latent classes; and 3) a portfolio choice model (PCM) that estimates...

User Acceptance and Public Perception Regarding Automated Driving Systems

Motamedi, Sanaz

Fully Automated Driving System (ADS) is one of the most innovative and fundamentally disruptive changes in transportation. This technology has the potential to resolve or mitigate current transportation problems, including reducing traffic accidents, congestion, energy consumption, and pollution. However, the extent of these impacts will depend heavily on public perception and widespread adoption of ADSs. To gain a better understanding of user acceptance and public perception related to ADS, extensive interviews were conducted with Tesla end-users who have experience using partial ADS (i.e...

Understanding California wildfire evacuee behavior and joint choice making

Wong, Stephen D, PhD
Broader, Jacquelyn C
Walker, Joan L, PhD
Shaheen, Susan A, PhD
2022

For evacuations, people must make the critical decision to evacuate or stay followed by a multi-dimensional choice composed of concurrent decisions of their departure time, transportation mode, route, destination, and shelter type. These choices have important impacts on transportation response and evacuation outcomes. While extensive research has been conducted on hurricane evacuation behavior, little is known about wildfire evacuation behavior. To address this critical research gap, particularly related to joint choice-making in wildfires, we surveyed individuals impacted by the 2017...

Theory of highway traffic flow: 1945 to 1965

Newell, Gordon F.
1995

Although we lack a complete theory of the motion of individual cars, there are many simple facts that even the most inexperienced driver knows and there are others which we could determine through experiment if we thought these facts were worth the effort required to find them. The lack of such a theory however, should not deter us from constructing a framework of possible theories consistent with what is known and seeing if such an incomplete theory can give any useful information about the gross aspects of traffic.

Fundamentals of Traffic Engineering - 16th Edition

Homburger, Wolfgang S.
Hall, Jerome W.
Reilly, William R.
Sullivan, Edward C.
2007

This syllabus serves as an introduction to the field of traffic engineering to professionals who are being assigned traffic engineering tasks for the first time and as a source of recent information for those already in the field. It is designed mainly for one-week short courses, but past editions have also seen increasing use in university engineering courses and for individual study. Traffic engineering is an ever-changing profession. New standards, guidelines, and basic texts rapidly replace older reference volumes. This 16th edition again includes new and revised material needed by...
