According to academia on the 24th, 'Phantom Jam' refers to a phenomenon where a line of vehicles comes to a long stop even without a clear cause like an accident or construction. A slight deceleration from one vehicle is transmitted to the car behind, gradually leading to a significant speed drop. It can start out trivial, but if one vehicle changes lanes or lightly applies the brakes before entering a tunnel, the car behind can slow down even more. And then The vehicle slows down even more strongly again, and since each driver has different reaction times before braking, the speed change increases as you go further back. There are also sections where this is highly likely, especially on uphill slopes, the speed can drop without the driver noticing, and at tunnel entrances, the sudden darkness often causes people to unconsciously slow down. In highway merging sections, frequent lane changes can narrow the distance between vehicles, increasing the likelihood of a chain reaction of deceleration. The most basic response drivers can take is to maintain a sufficient distance between vehicles and keep their speed steady; if they have enough distance from the car ahead, even if they slow down a little, they can gently slow down by taking their foot off the accelerator rather than immediately braking. Apparently, the speed change started by the car in front is absorbed in your own vehicle to reduce the deceleration passed to the car behind,,,,, Who's driving thinking about all these things??? Doesn't it make you think every driver on the highway is a veteran???????
