Impact of Advanced Driver Assistance Systems (ADAS) on Road Safety and Implications for Education, Licensing, Registration, and Enforcement

Thursday, November 10, 2022 • Link to session recording

Learn about the research that was undertaken to investigate the impact of Advanced Driver Assistance Systems (ADAS). ADAS are rapidly being developed and deployed, with an increasing number of new passenger vehicles equipped with advanced ADAS. These systems promise to improve safety by assisting drivers. However, there exists a critical gap in our understanding of the potential impacts associated with driver over-reliance and disengagement in vehicles equipped with ADAS.

This research involved the development and evaluation of approaches to improve drivers’ understanding of ADAS functionalities and the role and responsibilities of the driver. This included an experimental driving simulator study to examine the impact of training on drivers’ mental models. The outcome of this research includes an understanding of manufacturer offerings of common ADAS technologies in late-model vehicles, an examination of drivers’ understanding and perceptions of ADAS technologies, and evidence that targeted training may increase drivers’ understanding of these systems.

Detecting Subsurface Voids in Roadways using UAS with Infrared Thermal Imaging

Thursday, October 20, 2022. Link to session recording. Link to presentation
Link to Final Report from the research study

This webinar will present new research which validated an innovative method to detect roadway subsurface voids based on infrared (IR) imaging combined with unmanned aerial system surveying. The ability to detect voids before pavement collapse occurs is crucial for maintenance and replacement purposes. The failure of culverts and drainage piping underneath roadways creates sinkholes that represent a safety hazard to the traveling public and result in costly repairs and traffic inconveniences. Routine inspections of culverts are hard to perform and require expensive and time-consuming techniques such as drain cameras or ground penetrating radar. As part of this validation, laboratory and field tests were necessary to develop mission critical information that marked IR imaging’s current performance and solved issues that characterized this technique. Advanced image post-processing techniques were also developed to improve the detection accuracy of IR imaging, showing that thermal photogrammetry can detect roadway subsurface voids that are representative of failing culverts and drainage pipes. This research developed a more accurate nondestructive evaluation approach for assessing the conditions of real-world underground structures that are crucial for their inspection, maintenance, and management.

Evaluating the Safety Impacts of Flashing Yellow Permissive Left-Turn Indications in Massachusetts

September 22, 2022. Link to session recording.  Link to session presentation
Link to Final Report from the research study

The 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD) introduced the flashing yellow arrow (FYA) as a permissive left-turn indication. In the past decade, Massachusetts has begun implementing this traffic control device through a statewide retrofitting project at over 350 traditional protected-permissive left-turn traffic signals. This webinar will present a before/after implementation safety impact analysis, including a thorough benefit-to-cost analysis. The analysis evaluated the economic benefits of installing FYA signals, yielding a range of benefit-to-cost ratios across the three typical FYA treatment intersections (3-way with one FYA, 4-way with one FYA, and 4-way with two-or-more FYAs). The economic benefits suggest that the FYA signal retrofits should be widely implemented, regardless of intersection type. Overall, results provided overwhelming evidence that the FYA reduced the average annual number of injury-related crashes and led to a lower economic cost of injuries in all three of the treatment types of intersections investigated. This webinar will also highlight ongoing work investigating the impact of specific infrastructure elements at FYA intersections.

Panelists: Francis Tainter, Research Assistant Professor, University of Massachusetts Amherst; and Jim Danila, Assistant State Traffic Engineer, MassDOT

Tools for Crash Data Analyses and Developing the Massachusetts Strategic Highway Safety Plan

Link to session recording. Link to session presentation

This Innovation webinar session gave an overview of the ongoing work of developing the Massachusetts Strategic Highway Safety Plan (SHSP). A Strategic Highway Safety Plan (SHSP) is a statewide-coordinated safety plan that provides a comprehensive framework for reducing highway fatalities and serious injuries on all public roads. The SHSP identifies a State's key safety needs and guides investment decisions towards the strategies and countermeasures possessing the greatest potential to save lives and prevent injuries. For Massachusetts Strategic Highway Safety Plan, 14 emphasis areas have been identified, such as Lane Departure, Intersections, Pedestrian, Bicyclists, Speeding and Aggressive Driving and Safety of Workers on Roadways. Subject matter experts from across the state have been convening to develop action plans to reduce fatalities and serious injuries in these 14 emphasis areas. In addition to discussing the SHSP, this webinar also provided a live demo of the IMPACT data tool developed by MassDOT. This tool, which is being used heavily in the SHSP data analysis, is a great one-stop resource for accessing and analyzing all motor vehicle crashes in the Commonwealth.

Developing Improved Load Rating Procedures for Deteriorated Steel Bridge Beam Ends

November 19, 2021. Link to session video

This Innovation webinar session aims to provide improved evaluation procedures for structurally deficient bridges where corrosion is the common cause for steel bridge deterioration. The research methodology was organized in three phases that each employed real corrosion data. This work included an experimental program, extensive computational simulations, and parametric analyses and analytical work to develop a new proposed set of equations for the assessment of the remaining capacity of corroded beam ends. The experimental program was conducted in the Brack Lab at UMass Amherst.
