Planning and Accommodating the Micromobility Revolution and Its Impact on Public Health

Quistberg, Alex
Rodriguez, Daniel
2024

Micromobility has grown immensely over the past decade, encompassing both public shared systems and private ownership, and, as Burford et al. have found, a surge in user injuries and deaths has accompanied the growth. Micromobility refers to the use of small vehicles, such as bicycles and scooters, that are either human powered or electric. These vehicles are ideal for short trips—although electric-powered micromobility has expanded the potential distance range.

Connected and Automated Vehicle Policy Development for California

Shladover, Steven
2017

Connected and automated vehicles (CAV) have the potential to confer large benefits to California in economic development (job creation) and in improving the operation of its road transportation network. CAV systems are likely to become one of the most important application domains for modern information technology, employing large numbers of highly skilled people in research, development and implementation wherever the companies that are developing these systems find the local environment most hospitable. The CAV systems are expected to produce significant improvements in roadway capacity...

Streamlining Connected Automated Vehicle Test Data Collection and Evaluation in the Hardware-in-the-Loop Environment

Fu, Zhe

Lu, Xiao-Yun, PhD
2020

Quality data collection, processing, and analysis are foundational to good research, policy making and regulation development. With the rapid development of Connected Automated Vehicles (CAV) technologies, it is urgent for both researchers and policy makers to obtain and evaluate good quality CAV data to better understand CAV impacts. CAV hardware-in-the-loop (HIL) tests can expedite CAV performance evaluation and system implementation. This research aims at equipping an existing HIL test tool with data management functions. To this end, a database instance on MySQL has been integrated...

Recirculating Coherent Structures Inside the Cove of a Bulb Sealed Slat

The current aircraft noise has a large contribution provenient from the airframe in which the most relevant sources are the landing gear, the flap and the slat. The leading edge slat is a distributed noise source since it spans almost the whole wing extension. The presence of excrescences inside the slat cove can change significantly the recirculating flow and the characteristics of noise generated. Previous experiments showed substantial increasing in the narrow band peaks for the MD30P30N high-lift model in which the slat geometry included a bulb seal attached at some positions of its...

Are Traffic Safety Rules and Experience Sufficient to Make Children Safe Pedestrians?

Pedestrian injury is among the top causes of death in North American children ages 5-12 (NCIPC, 2014). Research documents a wide range of factors that contribute to child pedestrian injury risk, but many contributing factors remain unknown and unevaluated. This study considered two such factors: institution of safety rules by parents and children’s experience crossing streets. We hypothesized both presence of parental rules about traffic safety and greater child pedestrian experience would be associated with safer pedestrian behavior in children.

Teaching Pedestrian Safety in Virtual Reality: A Community-University Collaboration

In 2012 the US pedestrian fatality rate increased 6%, with 4,743 deaths occurring that year, equivalent to almost 13 fatalities per day and more than one every two hours. Children aged 5-9 years accounted for 22% of pedestrian fatalities (NHTSA, 2012). Studies suggest young children often negotiate dangerous street environments when travelling unsupervised by adults to and from school (Martin, Lee, & Lowry, 2007) so not surprisingly, community-based initiatives like Walking School Bus and Safe Routes to School are flourishing. A major limitation of such programs, however, is they...

The Influence of Self-efficacy and Perceived Safety in Neighborhood on Children’s Frequency of Walking to/from School

Walking is among the common transportation methods utilized by children to commute between home and school. Previous research indicates children’s intrapsychic characteristics such as self-efficacy play an important role in their decision to walk to/from school. Few studies have addressed the role of parent self-efficacy in these decisions. Furthermore, environmental factors such as neighborhood safety have mixed effects on children’s decision to walk to/from school

Associations Between Self-Efficacy and Children's Pedestrian Safety Following Training

Pedestrian injury is a leading cause of unintentional pediatric death. Hundreds of deaths related to pedestrian injuries occur every year in children under 18. Virtual reality interventions to teach children safe pedestrian behavior have shown success. Increasing self-efficacy is consistently related to the induction and maintenance of behavior change following a variety of interventions. In children, self-efficacy is associated with intervention-driven changes in health and academic behaviors. Self-efficacy is also linked to child and adolescent pedestrian engagement, with children...
