Emergency-Response Latency Budget
Detection → triage → dispatch → arrival latency as an additive budget with independent variance terms.
Design study plaque · Emergency-Response Latency Budget
ECSL is a public design-research surface under TLTE. No service exists. No operational authority is claimed. In an emergency call UK 999, EU 112, or the relevant Sri Lanka emergency line.Formulae
L_{\text{total}} = L_{\text{det}} + L_{\text{triage}} + L_{\text{dispatch}} + L_{\text{travel}}\sigma^2_{\text{total}} = \sum_i \sigma^2_i \;\;\Rightarrow\;\; P(L > L^\*) = 1 - \Phi\!\left(\frac{L^\* - \mu}{\sigma}\right)Variables
- L_det
- Detection latency (caller → operator)
- L_triage
- Triage latency (operator → category)
- L_dispatch
- Dispatch latency (category → vehicle move)
- L_travel
- Travel latency (R-field model)
- L*
- Target ceiling (e.g. 8 minutes)
Meaning
Decomposes 'time to help' into four independent stages, each with its own variance. Lets the design study show which stage to compress first — typically dispatch — before adding more stations. Anchored to NFPA 1710, NHS Ambulance Response Programme, and London Ambulance CAD reviews.

Anchored to NFPA 1710, the UK NHS Ambulance Response Programme and London Ambulance CAD reviews. Used here to show which stage to compress first — typically dispatch — before adding stations.
Becoming · இரு-அடுக்கு (2)
A budget a future Ambulance & Medical Response Unit would publish per district, with the variance term made explicit so the public reads honest probability, not headline averages.

Never coupled to a real dispatch number. No live ambulance data is used.
