Development of Instrumented Bikes: Toward Smart Cycling Infrastructure and Maintenance

Posted by ab3824 on September 29, 2022

Sponsor: U.S. Department of Transportation, Pacific Southwest Region 9 UTC

PI: Chun-Hsing Ho

Co-PIs: Brendan J. Russo and Steven R. Gehrke

This research project developed an instrumented bike with a sensor logger, a video device (e.g., GoPro), a mobile app, and a cloud server/website to detect real-time quality of cycling infrastructure systems (bike trails, sidewalks, pedestrian pathways, etc.). The instrumented bike is capable of immediately sharing the information with cyclists (road users) and governments/authorities (road managers) such that (1) cyclists… Read more

Evaluation of Sidewalk Autonomous Delivery Robot Interactions with Pedestrians and Bicyclists

Posted by ab3824 on

Sponsor: U.S. Department of Transportation, Pacific Southwest Region 9 UTC

PI: Steven R. Gehrke

Co-PIs: Edward J. Smaglik and Brendan J. Russo

Information and communication technology advancements and an increased demand for contactless deliveries after the Covid-19 pandemic outbreak resulted in the growing adoption of automated delivery services. Across university campuses, the deployment of sidewalk autonomous delivery robots (SADRs) has provided students, staff, and faculty a convenient last-mile delivery option. However, SADRs traverse campuses on pathways designed for pedestrians and… Read more

The Development of a Cooperative Safety Performance Assessment Framework for Connected and Automated Driving System-Equipped Vehicles

Posted by nbl42 on November 12, 2019

Sponsor: Institute of Automated Mobility (IAM) through the Arizona Commerce Authority (ACA)

PI: Brendan J Russo

Start Date: August 2019

The rapid development and testing of connected and automated driving system (ADS)-equipped vehicles (CAVs) in our urban communities raises serious concerns for public safety. To address these concerns, the Institute of Automated Mobility (IAM) established by Governor Ducey in Arizona has embarked on an innovative approach to driving safety performance assessment that cooperatively utilizes both infrastructure and vehicle data. Data from… Read more

Smart Technology Taxonomy and Evaluation for Maricopa Association of Governments (MAG)

Posted by nbl42 on July 24, 2019

AZTrans staff, along with colleagues at the University of Arizona and Arizona State University, have entered into a partnership with MAG to develop a taxonomy of Smart Region technologies and assist with independent evaluations of select Smart Region technology deployments.  Over the next several years, AZTrans faculty and students will work with MAG and the other partners to scope and evaluate the effectiveness of various Smart technologies in the MAG region.
