OVERVIEW
CARS for Road Curve Safety
Automated Curve Speed Evaluation
CARS utilizes advanced sensors and GPS technology to automatically measure curve radii, superelevation, and other critical parameters. This data-driven approach facilitates accurate determination of advisory speeds.
Compliance with MUTCD Standards
Ensure roadway signage and speed advisories meet federal requirements. CARS provides detailed reports aligned with MUTCD guidelines, aiding in proper placement of warning signs and chevrons.
Enhanced Traffic Safety
By accurately assessing curves and recommending appropriate speeds, CARS contributes to reducing accidents and improving overall road safety with real-time data collection.
