📖
What is the Calculationlogistics Hub Accessibility & How does it work?

Understanding the accessibility of a logistics hub requires integrating geographic distance with transportation efficiency. The farther a supply point is from the hub, the greater the time and cost incurred, especially when road conditions vary.

Transportation speed is moderated by the road quality factor, a dimensionless coefficient ranging from 0 (poor) to 1 (optimal). This factor adjusts the nominal speed to reflect real‑world conditions such as pavement type, gradient, and congestion.

By combining vehicle capacity, trip frequency, and handling time, planners can estimate the daily throughput that a hub can realistically support, guiding decisions on infrastructure investment and routing.

A = frac{C times N}{frac{D}{V times R} + H}
A = accessibility index (tons/day)  |  C = vehicle capacity (tons)  |  N = trips per day  |  D = distance (km)  |  V = average speed (km/h)  |  R = road quality factor  |  H = handling time (h)

Frequently Asked Questions
How does road quality affect transportation speed?
Road quality is represented by a factor ranging from 0 (poor) to 1 (optimal). This factor adjusts the nominal speed to account for pavement type, gradient, and congestion.
What factors determine the accessibility of a logistics hub?
Accessibility is determined by geographic distance and transportation efficiency. Farther supply points from the hub incur greater time and cost due to varying road conditions.
How does this calculator help in logistics planning?
This calculator helps in logistics planning by providing insights into how far a supply point is from the hub, considering transportation speed and road quality factors.
Can I use this calculator for multiple supply points?
Yes, you can input multiple supply points to assess their accessibility relative to the logistics hub.
What is the purpose of the road quality factor in this calculation?
The road quality factor adjusts the nominal transportation speed to reflect real-world conditions such as pavement type, gradient, and congestion.
