Summary
Optimizing passenger flow in metro stations is crucial. Placing mills barriers and encouraging 30-40% of passengers to use stairs significantly improves movement efficiency and safety.
Area of Science:
- Urban Planning
- Transportation Engineering
- Human Factors Engineering
Background:
- Transportation hubs face overcrowding due to high passenger volumes.
- Efficient passenger movement on vertical transit (stairs, escalators) is vital for safety and efficiency in multi-level metro stations.
Purpose of the Study:
- Analyze factors influencing passenger flow on vertical pedestrian transit facilities.
- Derive insights to minimize crowding and enhance movement efficiency.
- Propose strategies for improved passenger flow and safety-oriented evacuation.
Main Methods:
- Investigated escalator speed, passenger preference for stairs, and mills barrier design (layout, length).
- Explored guidance strategies on metro platforms.
- Detailed a safety-oriented evacuation layout.
Main Results:
- Mills barriers between stairs and escalators improve passenger efficiency; 1-1.5m length recommended.
- Increased passenger use of stairs (30-40%) reduces dwelling time and boosts efficiency.
- Removable facilities near bottlenecks expedite fire evacuation.
Conclusions:
- Strategic placement and design of mills barriers enhance passenger flow.
- Encouraging stair usage is an effective strategy for improving metro station efficiency.
- Effective planning of removable facilities is critical for rapid evacuation during emergencies.

01:14Design Example: Managing Concrete Workability
304
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

291
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

01:28Survey Safety
373
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

196.6K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

146.3K
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...
