OVERVIEW
Shared electric scooters (e-scooters) are fast becoming a mobility option in cities across the United States. This new micromobility mode has the potential to replace car usage for certain trips, which stands to have a positive impact on public health and sustainability goals. However, many aspects of this emerging mode are not well understood.This webinar explores the findings of three NITC studies examining transportation mode choices, safety, and public health outcomes of electric scooters.
KEY LEARNING OUTCOMES
By the end of this presentation, the participant will be able to:
- describe the ways in which electric scooters may provide new substitutive, complimentary or synergist transportation opportunities for different activities...

Joseph Broach, PhD candidate in Urban Studies, will discuss the results of his research, which models the propensity of children aged 6-16 to walk or bike to parks and school without an adult chaperone, extending existing work on children’s active travel in several ways: 1) focus on travel without an adult, 2) inclusion of school and a non-school destinations, 3) separate walk and bike models, 4) consideration of both parent and child attitudes and perceived social norms, 5) explicit inclusion of household rules limiting walking or bicycling.

OVERVIEW
How do people with intersecting marginal identities experience social exclusion as they travel via mass transit?
To answer this question, PSU researchers employed a qualitative method less common in transportation studies: photovoice. Researchers asked participants to describe the factors that shape their travel behavior and provide photographic data of their experiences. Then, they conducted in-depth video interviews to gain further depth and clarity regarding the visual data.
The findings from this study can help transit system designers better understand how experiences of harassment and discrimination across the entire users’ journey affects the riders’ decisions about whether and when to take transit, and the extent to which transit-related infrastructure is related to decisions about where to live or their access to long-term housing.

The proliferation of information technology in the transportation field has opened up opportunities for communication and analysis of the performance of transportation facilities. The Highway Capacity Manual relies on rules of thumb and small data samples to generate levels of service to assess performance, but modern detection technology gives us the opportunity to better capture the dynamism of these systems and examine their performance from many perspectives. Travelers, operations staff, and researchers can benefit from measurements that provide information such as travel time, effectiveness of signal coordination, and traffic density. In particular, inductive loop detectors show promise as a tool to collect the data necessary to generate such information. But while their use for this purpose on restricted‐access facilities is well understood, a great many challenges remain in using loop detectors to measure the performance of surface streets.
This thesis proposes 6 methods for estimating arterial travel time. Estimates are compared to simulated data visually, with input/output diagrams; and statistically, with travel times. Methods for estimating travel time are applied to aggregated data and to varying detector densities and evaluated as above. Conclusions are drawn about which method provides the best estimates, what levels of data aggregation can still provide useful information, and what the effects of detector density are on the quality of estimates....
