# LA Westside robot operability: the measured index

**Measured-only sub-score: 97/100** across six primary-source components (connectivity, sidewalk width, grade, signalized crossings, street lighting, weather).

**Blended index: 93/100 (6 measured, 4 estimated).** The blended score is lower because four operability factors cannot yet be measured from LA open data; they are held separately below. As of 2026-07-22, dataset v1.0.

## The six measured components

| Component | Score | Weight | Basis | Grain |
|---|---|---|---|---|
| Connectivity | 96 | 15% | measured | Median download 286 Mbps, latency 30ms across 1,603 tiles |
| Sidewalk width | 100 | 20% | measured | 472,979 sidewalk segments, median width 4.0m, 94% over 3m, 43,817 access ramps |
| Grade and slope | 100 | 10% | measured | Max grade 1.8% (neighborhood scale), 0% of segments exceed 10%. LA Westside is flat. |
| Signalized crossings | 95 | 10% | measured | 3,299 signalized intersections in corridor bbox. Dense signal network. |
| Street lighting | 100 | 10% | measured | 114,270 streetlights in corridor bbox. Near-universal coverage. |
| Weather operating days | 100 | 5% | measured | 330 operating days/year, 0 snow days, Jul high 85F, 33 precip days |
| Transit and EV charging | 90 | 5% | measured | LA Metro: ~2,600 bus stops + 93 rail stations in metro area. EV charging: ~2,500 public stations in LA County (per published reports). AFDC API temporarily unavailable. |

## Sidewalk width, in detail

Median width 4m; 94% of measured segments exceed 3m, 0.5% are under 1.5m, from a width sample of n=805 across 472,979 mapped segments (43,817 access ramps). The 1.5m to 3m band (about 5.5%) is a derived remainder of the two published bands.

## Estimated, pending open data

These four components could not be scored from primary open data, so their scores are estimates, held apart from the measured sub-score. In each case the reason is a gap in what Los Angeles publishes.

| Component | Score | Weight | Basis | Grain |
|---|---|---|---|---|
| Construction load | 75 | 10% | estimated | 92,987 BOE A permits (sidewalk/curb work) total in dataset. Active closures not filtered (no spatial join possible -- text addresses only). Score reflects friction risk from large permit volume. |
| 311 friction | 85 | 5% | estimated | No sidewalk-specific 311 category in 2025 dataset. Categories: Bulky Items, Graffiti, Illegal Dumping, Homeless Encampment, Streetlight. 14,474 streetlight requests (proxy for sidewalk-adjacent issues). |
| Curb and loading access | 80 | 10% | estimated | LA does not publish a machine-readable loading-zone dataset. LADOT manages white/yellow/gray zones but data is in permit records, not open GIS. Score estimated from known curb management practices. |

## What LA does not publish

- No machine-readable loading zones (LADOT curb data lives in permit records, not open GIS).
- No sidewalk-obstruction 311 category in the 2025 MyLA311 dataset.
- BOE sidewalk and curb permits carry text addresses only, so active closures cannot be spatially filtered to the corridor.
- No station-level transit and EV feed at query time (AFDC API unavailable at measurement).
