The following ADAS applications are enabled by AV camera technology:
- Lane Departure Warning
- Lane Keeping Assist
- Distance Warning
- Pre-crash Vehicle Preparation
- Collision Warning
- Automatic Emergency Braking
- Basic Adaptive Cruise Control
- Traffic Sign Recognition
- Auto Head Lamp (on/off)
- High Beam Control.
Recommendations for infrastructure upgrades to improve function ADAS and AV Camera technology applications.
- Very wide or narrow lane marks are uncommon and should be discouraged; 12 to 15 cm is the ideal width as they are most common; lane marks under 10 cm or over 25 cm wide should not be permitted
- Very long dashes can be mistakenly detected as solid; dashes should be limited to a maximum length of 5 meters
- Markings with higher contrast are easier to detect; in some scenarios the combination of lighting and concrete causes yellow marks to be less visible than white marks
- White road markings are better than yellow
- Under certain conditions (angle of the sun or wet roads at night) tar seams can appear as lane marks
- Recommend using less reflective material
- Road construction: overlap of old and new lane markings can be confusing; hiding irrelevant marks can also be useful for humans
- Cat’s eye retro-reflectors can extend the range of lane detection at night, particularly in inclement weather conditions
- Botts’ dots can make detection difficult, especially if they are dirty or have worn-away paint. The study suggested using dots with retro-reflectors to improve visibility.
