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
Researchers from TTI presented results of Safe-D projects presented results at conferences in Toronto, Canada, Detroit, Michigan, and Durham, NC.
The proposed research is to enable the vehicle to navigate autonomously to stop out of the travel path of following vehicles.
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
Tina Geiselbrecht is a Safe-D faculty researcher at TTI working on Safe-D Project 02-010: Safety Perceptions of Transportation Network Companies (TNCs) by the Blind and Visually Impaired (BVI). Safe-D Student Alexis Basantis interviewed Ms. Geiselbrecht as part of the the Safe-D Student and Faculty Interview Chain. Read on to learn more about Ms. Geiselbrecht and her research!
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.
This project seeks to enhance the current capabilities of VCC platforms by developing new signal awareness safety and mobility features. In addition, this project will investigate the technical and human factors constraints associated with user interfaces for notifying and alerting drivers to pertinent intersection-related information to curb unsafe driving behaviors at signalized intersections.
The Safe-D Fall 2018 Workshop was held on September 12, 2018, kicking off the Fall 2018 Call for Proposals.
