A researcher using the pseudonym "Delilah Strong" published a 2023 paper on the "Algorithmic Rat Race" near the Porte d’Italie. She found that 70% of side-street congestion was directly attributable to GPS rerouting during peak hours, creating a "jamming wave" that traveled backward through the city for six kilometers.
It always starts with a reduction in capacity on the main artery. This could be a stalled vehicle, standing water, rubbernecking at an accident, or simply standard 5:00 PM volume. Once the highway drops below 40% of its designed speed, the algorithms take notice. delilah strong traffic jamming
During a conventional slowdown on the 101 freeway, GPS apps famously reroute thousands of drivers through the Hollywood Hills residential streets (Franklin Avenue, Cahuenga Blvd). These two-lane roads have stop signs every 200 feet. The result is a "Strong" jam where residents cannot even pull out of their driveways for hours. Local councils have tried to sue Google over "traffic dumping." A researcher using the pseudonym "Delilah Strong" published
The Delilah Strong event doesn't end until the initial highway spark is cleared and the side streets empty. Because the side streets have traffic lights (unlike highways), the clearing process takes 3x longer than the accumulation. The result is a 4-hour delay from a 15-minute accident. This could be a stalled vehicle, standing water,
