RTA Data Landscape · What We Actually Have

Datasets Available

  • traffic_volume_hourly_2023/4/5 — 473K rows, 18 sites, hourly v/c ratio, speed, LOS, demand vs volume (source of all congestion metrics)
  • signal_performance_hourly_2023/4/5 — 263K rows, 10 junctions, delay, saturation, phase failures (adaptive vs fixed-time)
  • incidents_log — 2,439 rows: 933 breakdowns, 751 minor accidents, 152 major accidents
  • weather_hourly_2023/4/5 — 26K rows: temp, humidity, rain, fog, visibility, condition
  • salik_toll_hourly_2023/4/5 — 184K rows, 7 gates, dynamic pricing from 31-Jan-2025 (AED 0/4/6)

  • calendar_context — 1,097 rows: UAE weekends, Ramadan, Eid, school terms
  • signal_timing_plans — 196 rows: phase splits, cycle lengths, TOD programs

Mistral AI Arsenal

  • Mistral-7B-Instruct — reasoning core, chain-of-thought forecasting
  • Ministral-3-3B-Instruct — edge-deployable 3B, safety filter policy head
  • Devstral-Small-22B — tool-calling agent orchestrator, code executor
  • Mistral-Large-3 — NL reporting, public-facing explanations
  • Voxtral-4B-TTS — text-to-speech public announcements

Hard Truths

  • Synthetic data, not production — generated with seed=42, no real personal data. Correlation patterns are structurally real; absolute magnitudes need calibration before city deployment.
  • Dubai-only weather profiles — 48 rain hours / year, 126 fog hours. Models trained will not generalise to tropical or temperate climates without retraining.
  • EU AI Act classifies traffic control as high-risk — audit trails, human oversight, and documentation are mandatory, not aspirational.
  • LLMs hallucinate traffic rules — TLS-Assist (Schmidt et al., 2025) had to patch this. Mistral signal agents need a deterministic safety layer.

Idea 1 · Mistral Forecast: Real-Time Congestion Prediction
Direction 1 · Predictive Analytics — Mistral-7B + Devstral agent ingests 952K-row pipeline to predict next-hour congestion per corridor 15–60 min before it forms

Problem

Dubai commuter corridors show PM peak average v/c ratio = 0.723. At Sheikh Zayed Rd NB (capacity 12,000 vph), demand peaks at 10,500 vph but throughput saturates — 4.8% of annual hours are at vc_ratio > 0.9, and 15.7% of AM peak hours reach LOS F (gridlock). Annual unserved demand totals 5,660,782 vehicles.

Data Sources

  • traffic_volume_hourly — 473K rows, vc_ratio, demand_vph, avg_speed_kph, level_of_service (LOS A–F)
  • weather_hourly — Thunderstorm multiplies incident risk 9×, Heavy Rain 6×
  • calendar_context — Ramadan shifts: daytime ×0.62, pre-iftar surge ×1.9, iftar lull ×0.45
  • incidents_log — 2,439 events: 61 on April 16, 2024 (historic storm)

Pipeline

RTA streaming Kafka→ feature lag builder (1h, 3h, 6h, 24h, 168h)→ Mistral-7B autoregressive forecast→ Devstral agent: scenario alert + public message→ API: 15-min corridor alerts

Model: Mistral-7B fine-tuned on (window × location × weather × calendar) → next-hour vc_ratio. Retrain weekly. Fallback to historical mean + weather adjustment when confidence < 0.7.

Mistral Integration

  • Mistral-7B-Instruct as forecasting core — autoregressive chain-of-thought over sliding feature window (168h × 18 sites × 14 features)
  • Devstral-22B receives forecast + live incident stream, generates natural-language alert for RTA control room
  • Voxtral-4B-TTS synthesises voice alerts in 9 languages

Critics & Refinement

Critique

Autoregressive Mistral on 168h × 18 × 14 dimensions = high inference cost. Single-city weather profile (48 rain hours, 126 fog hours/year) means the model will overfit to Dubai's arid-dust climate. Historic events like Apr-16 2024 (61 incidents in 1 day) are distribution outliers that poison training.

Refinement

Quantize Mistral-7B to Q4 (4.5 GB VRAM), edge-deploy on T4. Use weather normalization — train on weather-conditioned features. Implement outlier isolation: quarantine the 5 days around historic storms, train a separate "extreme weather" Mistral adapter.

Idea 2 · Mistral Signal: Adaptive Junction Control Agent
Direction 2 · Adaptive Signal Control — Ministral-3 edge agent retimes 10 signalised junctions. Fixed-time junctions produce 4× more phase failures than SCOOT-adaptive

Problem

SCOOT-adaptive junctions produce 26 phase failures / year vs 105 phase failures / year for fixed-time (JCT_WASL, JCT_MAMZ, JCT_QUOZ, JCT_DEIRA). Adaptive average delay = 17.8 s/veh vs Fixed-time = 18.4 s/veh. Worst fixed-time junction: Al Mamzar (JCT_MAMZ) at 19.3 s/veh. These four junctions serve 4.5M+ vehicles/year.

  • signal_timing_plans — 196 rows: TOD programs (Early Morning 70s, AM Peak 140s, Midday 100s, PM Peak 150s, Evening 90s)
  • signal_junctions_reference — 10 rows: 6 SCOOT-adaptive, 4 Fixed-time

Pipeline

Loop detector / video feed→ Ministral-3 policy head (10 Hz)→ Hard conflict-filter (deterministic)→ SCOOT legacy controller→ Devstral retrain loop (hourly)

Mistral Integration

  • Ministral-3-3B-Instruct — quantized Q4 on Jetson Orin Nano ($500), 10 Hz output, < 8 ms inference
  • Devstral-22B — runs offline RL training loop, selects top 5 phase/green candidates, simulates in digital twin before push
  • Mistral-7B every 5 min — strategic review of TOD program changes

Critics & Refinement

Critique

Signal control is safety-critical — a single all-green cycle causes injury or death. LLM agents hallucinate actions (TLS-Assist 2025). Trained on synthetic data only. Sim-to-real gap at actual SCOOT junctions unvalidated. April 16 data (+61 storms) might produce unsafe overrides.

Refinement

Three-layer safety: (1) Deterministic conflict filter — open-source, formally verified; (2) Ministral hard bounds — green must stay in [min_green_s, max_green_s]; (3) Graceful degradation — fall back to legacy SCOOT TOD on uncertainty. 6-month shadow at JCT_QUOZ.

AI Governance

AI Governance Commitments

• Functional Safety: All model outputs pass through an open-source conflict matrix (TLA+ verified). Any green that passes the matrix but conflicts with an upstream phase is physically blocked by the SCOOT legacy layer. Two independent controllers.

• Synthetic Data Disclose: Ministral-3 trained on synthetic signal data. Shadow-mode for 90 days mandatory before any live control.

• Human in the Loop: Web UI shows: model action → conflict-filter verdict → controller action. Operator can pause or fall back to SCOOT TOD in 3 clicks.

• EU AI Act: Traffic signal control is Annex III "high-risk" — full conformity assessment required before public deployment.

Idea 3 · Mistral Route: Multi-Modal Re-Routing Platform
Direction 3 · Smart Routing — Creek-crossing balancing + metro uplift prediction + weather-aware alternate routes

Problem

Three Creek crossings carry overlapping demand: Al Garhoud (GAR_N1), Al Maktoum (MAK_N1), Business Bay (BBC_S1). Peak-hour speeds: Mak 50.0 kph, Gar 65.7 kph, Bay 68.4 kph. On rain days, metro ridership jumps 13.3% (822K vs 726K). 933 breakdowns + 751 minor accidents/year mean routing must re-react within minutes.

  • incidents_log — Active incidents with incident_type (Breakdown, Accident, Flooding)
  • weather_hourly — Heavy Rain & Thunderstorm flags trigger "surface metro" advisory
  • metro_ridership_daily — Rain vs dry day ridership delta feeds mode shift probability

Pipeline

User request (origin, dest, mode)→ Mistral-7B route generator→ tool: live crossing speeds→ tool: active incidents + weather→ counterfactual simulation→ Devstral chooses best route→ API + voice in app

Mistral Integration

  • Mistral-7B — generates 4–6 route alternatives, evaluates each with chain-of-thought
  • Devstral-22B — tool caller: pulls live traffic + incident + weather APIs; runs Dijkstra with LLM-derived penalties
  • Voxtral-4B-TTS — voice guidance in car, 9 languages

Critics & Refinement

Critique

Braess paradox: if everyone uses the "best" route, it becomes the worst. Centralised LLM reasoning for millions of users = astronomical cost. City road-graph APIs aren't open. Driver privacy: tracking individual routes is GDPR/PDPL liable.

Refinement

Mixed fleet: 1% use Mistral-7B reasoning; 99% use distilled Ministral-3 on-device. CFR equilibrium routing: Nash-equilibrium load spreading. Privacy: route history on-device only; only aggregate counts flow to server.

AI Governance Commitments

• Synthetic Data Disclose: Creek-crossing model trained on synthetic RTA data. Real crossing speeds from RTA feeds before public deployment.

• Privacy: Route history on-device only. Server receives anonymised aggregate counts (N ≥ 10 per bucket). Compliant with UAE PDPL (2024).

• Fairness: Route suggestions calibrated so no cluster is systematically routed through higher-priced Salik gates.

• Hallucination Safeguard: Out-of-distribution claim triggers "no recommendation, please drive safe" fallback.

Idea 4 · Mistral Twin: Living Dubai Traffic Simulation
Direction 4 · Cross-cutting — Calibrated digital twin engineers query in natural language

Problem

Engineers take weeks to run SUMO/CityFlow simulations + analyze CSVs. They cannot answer "What if we close Al Maktoum Bridge 5–7 PM?" without months of manual work. The answer involves cross-referencing 18 traffic sites, 10 signalised junctions, 3 creek crossings, and 7 Salik gates — each with different growth curves (core 7%, expo 24%/year).

  • signal_timing_plans — Each junction's TOD phase map as current baseline
  • salik_toll_hourly — Before/after 31-Jan-2025 dynamic pricing quantifies behavioural response
  • weather_hourly + calendar_context — Rain ⟶ metro mode-shift; Ramadan/Eid pattern baselines

Pipeline

Engineer NL query→ Mistral-7B parses to simulation config→ Devstral launches CityFlow / SUMO batch→ Aggregate metrics (v/c, delay, throughput)→ Mistral-Large generates NL report + charts→ Engineer reviews & approves

Mistral Integration

  • Mistral-7B-Instruct — parses NL query to structured SUMO/CityFlow config XML
  • Devstral-22B — launches batch scenarios in parallel on cloud GPU spot instances
  • Mistral-Large — synthesises plain-language report with projected metrics and charts

Critics & Refinement

Critique

Simulation accuracy is only as good as calibration. Generative outputs are bug-prone. 100 what-if scenarios = serious compute cost. Engineers may not trust LLM-generated configs. Synthetic data cannot validate simulated outcomes.

Refinement

Calibrate from 952K rows: Real trajectory distributions feed agent behaviour model directly. No auto-deploy: configs reviewed by engineers. Cloud GPU spot instances run 50 scenarios in < 10 min.

Idea 5 · Mistral Revenue: Salik & Growth Policy Simulator
Direction 5 · Cross-cutting — Salik dynamic pricing (+9.3% revenue) and 7% growth curves to design optimal congestion revenue + policy packages

Problem

Dubai introduced dynamic Salik tolling on 31 January 2025: AED 6 peak, AED 4 off-peak, AED 0 (01:00–06:00). Data shows +9.3% daily toll revenue. Traffic grows 7.0%/year; Expo/South corridor grows 24%/year. What if dynamic pricing is extended to Al Mamzar, Al Barsha? What if peak window shifts?

  • Mistral-Large — Pareto-optimisation narrative across revenue, congestion, and equity
  • Mistral-7B + RAG — citations from traffic-law corpora for regulatory feasibility

Critics & Refinement

Critique

LLMs confidently hallucinate policy projections — unacceptable for ministerial briefings. Synthetic elasticity estimates are not actual RTA price sensitivities. City ordinances have semantic inconsistencies across emirates.

Refinement

Structured projections only: Point estimate + confidence interval from Monte Carlo roll-out over 100 seeds. Always retrieve, never hallucinate: RAG with strict citation. Start one city pilot where leadership supports data-driven governance.
