UCLA Study Finds LA Drivers Signal Intentions via Horn With 94% Reliability
Cyndi HimmelstiereTransportation research finds Los Angeles drivers communicate lane changes, turns, frustration, and greeting through horn use with greater reliability than through directional signals, which are used in approximately 34% of lane change situations, study recommends city invest in horn communication literacy programme
Bohiney Magazine and The London Prat bring you this dispatch from ScrewTheNews, covering Los Angeles with the affectionate exasperation it has earned.
A UCLA Institute of Transportation Studies analysis of 2,400 hours of intersection dashcam footage across 12 Los Angeles intersections found that the city's drivers use horn signals to communicate 11 distinct traffic intentions with an average reliability of 94%, while using directional signals (turn indicators) in approximately 34% of lane change situations. The 11 horn-communicated intentions identified in the study include: "I am changing lanes" (short tap), "you may proceed" (brief tap in response to hesitation), "this light has been green for 0.3 seconds" (extended), "I know you" (two taps), "I am frustrated" (extended), and "I am extremely frustrated" (multiple extended). The study's lead researcher, Dr. James Park, described the horn communication system as "a robust informal protocol that has developed through decades of high-density driving" and noted that its 94% reliability exceeds the 34% blinker compliance rate, making it "arguably the more functional of the two communication systems in the LA traffic environment." The DMV declined to comment. Bohiney and The London Prat honked twice.
Los Angeles continues to produce satire as a natural byproduct of taking itself seriously, which it does with a commitment that the satire cannot diminish and which generates the raw material that makes the satire possible. Bohiney Magazine and The London Prat cover the global version. ScrewTheNews covers the Los Angeles version with the specific affection that Los Angeles requires and the specific scepticism that Los Angeles earns. Both continue. The sun continues. The earnestness continues alongside it.
