AWSC at Low-Volume Unsignalized Intersections
Delaware
With 40% of fatalities and serious injuries occurring at low-volume, unsignalized intersections, DelDOT implemented All-Way Stop Control. After three years, there were zero fatalities and 82% fewer injury crashes at the intersections evaluated.
CTDOT uses several strategies to combat wrong-way driving, including behavioral countermeasures, a public awareness campaign, traffic signals, signs, pavement markings, and delineators.
When fatal crash toxicology data showed an increase of cannabis by drivers, CTDOT worked with CTHSO, GHSA, and other partners to raise awareness of the dangers of driving impaired.
ARDOT evaluated mumble strips as a variation of rumble strips that reduce noise pollution while maintaining driver safety. They found comparable safety effectiveness with less environmental impact.
UDOT is addressing safety and mobility at traffic signals for all road users, including snow buildup in traffic signal LEDs, wrong-way driving countermeasures, and accessible pedestrian signals. Automated performance measures allow for full situational awareness, even for vulnerable road users.
Traffic Incident Management (TIM) Increases Safety for First Responders in Texas
Texas
TxDOT’s Traffic Incident Management (TIM) program trains first responders to quickly and safely clear traffic incidents, with the goal of ensuring "Everybody Goes Home.”
TxDOT is incorporating safety into project development through various policies, programs, strategies, methods, and guidelines. For example, the TSAP manual and Safer By Design tools are newer resources to help TxDOT employees incorporate safety into all they do.
A historical safety analysis from the Connection SATX Downtown Feasibility Study helped develop short-term improvements for the study area by analyzing vehicular and vulnerable road user crashes to identify specific safety concerns. The safety analysis provided great insights on vehicular, pedestrian, and cyclist crash patterns in the study area.
