When driving on highways, the easiest place to get stuck is often not at toll booths, but at the intersection of ramps. Although the road has widened, it always slows down as soon as it merges. This is not accidental, but the inevitable result of the combination of physical rules, driving behavior, and road design.
1、 Road structure: natural bottleneck caused by speed difference
1.1 Collision of Two Traffic Flows with Completely Different Speeds
The cars on the main line travel at a speed of 100km/h, アダルトグッズ,while the cars on the ramp only have a speed of 40-60km/h.
The huge speed difference requires the mainline vehicles to slow down and avoid, instantly creating a "flow blockage".
1.2 Lane suddenly compressed
The main line is smooth before merging, and merging is equivalent to temporarily reducing the number of lanes,
The traffic flow remains unchanged, the traffic space becomes smaller, and congestion naturally occurs.
2、 Driving behavior: Everyone's self-protection leads to overall stagnation
2.1 Main line vehicles are not allowed, ramp vehicles dare not enter
Ramp vehicles require a safety gap to merge, but mainline vehicles usually do not yield.
As a result, the ramp cars queued up and blocked the rear.
2.2 Frequent lane changes, sudden braking, and rush driving
Everyone in the merging area is looking for gaps, interweaving, and stopping quickly,
The traffic flow is constantly interrupted, the overall speed decreases, and congestion is amplified.
3、 Design and flow: Confluence points are inherently fragile
3.1 The acceleration lane is too short
The acceleration lanes on many ramps are too short, 乳首ローター,forcing vehicles to merge before they can accelerate,
Further exacerbating the chaos.
3.2 Peak traffic instantly exceeds the upper limit of tolerance
The design capacity of high-speed merging points is limited,
At peak hours, the traffic flow instantly exceeds the standard and directly becomes a parking lot.
Conclusion
The congestion at the intersection of highways is not due to narrow roads, but rather the combined effect of speed difference, refusal to yield, and lane compression.
This is the most vulnerable and prone to collapse position on the highway, and also the most common source of traffic congestion.
