Summary
We developed a new dataset of road link travel speeds in Chengdu, China. This data supports research in traffic, transportation, and logistics by showing realistic speed variations.
Area of Science:
- Traffic engineering
- Transportation science
- Logistics management
Background:
- Road network travel speeds are crucial for traffic, transportation, and logistics research.
- Existing datasets may not capture the realistic variations and randomness of urban link travel speeds.
Purpose of the Study:
- To develop a comprehensive dataset of road link travel speeds in a major Chinese megacity.
- To provide realistic traffic data for data-driven decision-making in transportation and logistics.
Main Methods:
- Collected travel speed data for each road link in Chengdu, China.
- Integrated travel speed data with the actual road network map.
- Captured data across different time periods to reflect temporal variations.
Main Results:
- The dataset includes realistic variations and randomness of urban link travel speeds.
- The data reflects diverse urban road network structures present in Chengdu.
- The dataset is representative of a megacity in Western China.
Conclusions:
- The developed dataset enhances research capabilities in traffic, transportation, and logistics.
- This resource enables data-driven decision-making for real-world transportation challenges.
- The dataset provides valuable insights into urban traffic dynamics.

01:04Travelling Waves
6.9K
A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it is deformed.
Water waves, sound waves, and seismic waves are some examples of mechanical waves. For water waves, the wave propagation medium is...

01:27Traveling Waves: Lossless Lines
471
The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.

340
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

02:04Covalently Linked Protein Regulators
8.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

02:26Protein Networks
4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

02:18Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
