The phrase "at bottlenecks" is correct and usable in written English.
It can be used to refer to points in a process where congestion or delays occur, often in discussions about workflow or efficiency.
Example: "The project faced significant delays at bottlenecks in the approval process."
Alternatives: "during delays" or "at critical points".
Shipments piled up at bottlenecks, particularly along the Mexican border.
These included lanes of uniform walking directions, oscillations of the pedestrian flow at bottlenecks, and "stripes" of intersecting flows.
On the borders of Hungary and Serbia, thousands of people meet at bottlenecks, desperate to get further into Europe.
I know this because a while ago I began asking around — politely, I mean, trying to avoid words like "bullying" and "lowlife," making inquiries as to who lines up at bottlenecks and who sidezooms.
"The rules of the road for the Infinite Corridor include: stay to the right, limit group size, pass on the left, form a line at bottlenecks, don't stop/slow down, no tailgating, traffic within corridor has right of way, no physical contact and no eye contact.
For example, when the route narrows at bottlenecks, so that the maximum flow rate is lower, the model predicts how congestion might develop and spread elsewhere.
Under such circumstance, several novel unconventional intersection designs, including the well-recognized continuous flow intersection (CFI) design, are originated to improve the capacity at bottleneck intersections.
It benefits from the CFI concept to enable simultaneous move of left-turn and through traffic at bottleneck intersections, but does not need installation of sub-intersections.
Several expeditions were on the mountain over the weekend, and some reports said about a dozen climbers were stranded at Bottleneck, a region known as the "Death Zone" because bodies begin degenerating from lack of oxygen.
Automation level is more than plant A and cycle time at bottleneck station is 90 s.
We assume that the interference measurement point is located at bottleneck SU v b for convenience.
