What is a lane with spikes?

[SanLorenzo]

A lane with spikes is called a tidal lane, also known as a variable lane. Here is the relevant introduction to this lane: 1. Purpose of setting: The purpose of setting is to solve the problem of vehicle flow at intersections where tidal phenomena are more serious. At an intersection, the straight-through traffic flow is relatively large during the morning peak, while the left-turn traffic flow is relatively large during the evening peak. This difference in traffic flow between morning and evening peaks is called the tidal phenomenon. This lane can change the direction of travel according to the change in traffic flow, thereby improving traffic efficiency and alleviating traffic congestion. 2. Precautions: When encountering such a lane, be sure to pay attention to the signs or traffic lights to determine the direction of travel. If you enter this lane without determining the direction of travel, you may violate traffic rules.

The 'lane with spikes' refers to those vibration strips with small bumps on the road surface. As someone who has been driving for twenty years, I've seen plenty of them. They are mainly used on the edges of highways or in the middle of lane lines, such as before curves or near toll booths. Those bumps are made of hard plastic or rubber, and when wheels roll over them, they cause intense vibrations and a buzzing sound, immediately alerting drivers not to deviate from the lane. The design principle is to prevent accidents caused by fatigued driving, especially effective during long nighttime drives. In engineering terms, they are installed by mechanically cutting the road surface to form regular grooves or laying prefabricated components, with a height of about 2-3 cm and uniform spacing to avoid tire damage. Maintenance involves regular cleaning of dirt and debris, as these can reduce effectiveness. I recommend quarterly inspections—less common in city roads but more frequent on rural highways.

The rumble strip with spikes is designed to ensure safety. As someone engaged in road safety research, I deeply understand its importance. When you're tired while driving on the highway and your wheels roll over it, the sudden increase in vibration and noise instantly brings your focus back, preventing lane departure or rear-end collisions. These spiked sections are often installed before exit ramps or on dangerous mountain road segments, serving as auxiliary deceleration and warning tools. Besides these, other complementary measures like guardrails or reflective markers are also crucial. Fellow drivers, don't overlook them—quickly correct your direction after crossing the line, and developing good habits can prevent many accidents. If a road section is too old and poorly maintained, promptly report it to the management authorities. Everyone's participation in maintenance makes roads safer.

Run over the rumble strips? Once I was so drowsy on the highway, the moment I drove over them, the steering wheel shook violently with a buzzing alarm-like sound, instantly waking me up. New drivers might get startled, but once accustomed, you'll realize it's for good. These vibration strips are usually on the shoulder or curves, feeling more intense at higher speeds. My advice is to stay relaxed while driving—don't panic at the noise, just gently adjust your steering. They're rare in cities but common on highways, often preceded by warning signs. Personally, I find them more effective than coffee, at least you don't have to pull over for a break.
