Abstract Child safety concerns are among the strongest impediments to children walking or biking to school, but some students must walk or bike due to financial or other circumstances. These travel modes are more than twice as common among students from low-income households than students from higher income households. The Safe Routes to School (SRTS) program fosters opportunities for students to walk and bike to school safely and routinely. This study provides insights into the SRTS program’s effectiveness and potential to improve walking and biking safety in socially vulnerable communities by evaluating the program’s impact on schools in the Chula … Evaluating the Safe Routes to School (SR2S) transportation program in socially vulnerable communities in San Diego County, California
The proposed research is to enable the vehicle to navigate autonomously to stop out of the travel path of following vehicles.
Researchers from TTI presented results of Safe-D projects presented results at conferences in Toronto, Canada, Detroit, Michigan, and Durham, NC.
Abstract The number of electric vehicles on the road increases exponentially every year. Due to the quieter nature of these vehicles when operating at low speeds, there is significant concern that pedestrians and bicyclists will be at increased risk of vehicle collisions. This research explores the detectability of six electric vehicle acoustic additive sounds produced by two sound dispersion techniques: (1) using the factory approach versus (2) an excite transducer-based system. Detectability was initially measured using on-road participant tests and was then replicated in a high-fidelity immersive reality lab. Results were analyzed through both mean detection distances and pedestrian probability … A Data Driven Approach to the Development and Evaluation of Acoustic Electric Vehicle Alerting Systems for Vision Impaired Pedestrians
Recording Title/Project/Date Speaker Webinar Overview Link (YouTube) Title: Micromobility Regulation Best Practices Review: Scoot Now, Regulate Later Project: Safe-D TTI-05-04 Date: March 26, 2024 Gretchen Stoeltje, J.D., Texas A&M Transportation Institute This webinar will present the scope, methodology and findings of the Safe-D project Micromobility Regulation Best Practices Review (aka Scoot Now, Regulate Later). This project sought to locate data about e-scooter crashes, their actual causes, who or what party was responsible for the cause, and who or what party might be legally liable for the cause based on a combination of statutory and contractual assignment of that liability.

This project will develop a framework which will bring together traditional and emerging data sources, and will be developed in such a way that it can be up- or down-scaled based on the available data sources of a study area. The exposure estimation output will then be used for crash assessment tailored to the needs of the study area.
Automated vehicle technologies (AV) have the potential to become one of the most highly disruptive technological applications of our century.
This project will analyze these already-collected NDS data to evaluate the safety and mobility benefits of automated vehicle technologies AVT for senior drivers.

Abstract Safety issues that stem from commercial truck parking shortages are a national concern. National hours-of-service (HOS) regulations limit drivers’ time on the road, in an attempt to increase safety by limiting fatigue; thereby, creating a need for drivers to locate safe, secure, and legal parking wherever they are when or before they hit their limits. In addition, the recent rule mandating the use of electronic logging devices (ELD) to electronically record a driver’s Record of Duty Status (RODS), replacing the HOS paper logbooks, further exacerbates drivers’ needs to find adequate parking. If drive time is exhausted where there … Connected Vehicle Information for Improving Safety Related to Unknown or Inadequate Truck Parking
