MetroSMS™: Autonomous Passenger Telephony in < 2 Seconds
Universal, app-free transit arrival predictions over standard carrier cellular SMS. Riders text an intersection, route number, or 4-digit stop code to receive verified arrival countdowns and detour bulletins. 100% single-segment GSM-7 compliance with zero mobile app downloads or data plans required.
Carrier-Grade Architecture
Engineered from First Principles
Sub-second response latencies backed by mathematical arrival smoothing and cryptographic carrier verification.
Monotonic Countdown Guard
Eliminates GPS drift jitter. When a bus is within 3 minutes of a stop, predicted arrivals are mathematically guarded so countdowns never jump backward in successive rider queries.
Single-Segment GSM-7 Packing
Every message strictly conforms to a single 160-character GSM-7 carrier segment. Zero split-message fragmentation, zero carrier overage charges, and 100% deliverability on prepaid devices.
EWMA Velocity Smoothing
Exponentially Weighted Moving Average (alpha = 0.35) continuously dampens traffic stoplight spikes and temporary signal holds, delivering accurate real-time arrival estimates.
MetroAlert™ & MetroRemind™
Riders text `ALERT 66` or `REMIND 15` for proactive detour bulletins, snow route notices, and arrival countdown alerts. Fully autonomous opt-in and TCPA-compliant unsubscribe.
Bilingual Semantic Parsing
Handles informal commuter queries in English and Spanish ("Lomas y San Mateo", "Bus 66 East", "parada 1042"). Sub-15ms inverted GTFS lookups without external AI API dependencies.
Title VI & Digital Equity
Over 30% of transit riders have prepaid data restrictions or basic non-smartphones. MetroSMS bridges the digital divide with 100% universal access on any cellular phone.
