SignalDecoded

A neighborhood-facing dashboard and mobile app that translates how AI-controlled traffic signals at your local intersection are making timing decisions, with plain-English explanations of queues, phase choices, and a one-tap way to report confusing patterns to the city.

Target user

urban commuters and neighborhood association leaders who want to understand and challenge traffic-light behavior on their block

Features
  • Plain-English 'why this light is red' overlays for any signalized intersection, generated from live signal-timing data and queued-vehicle counts
  • Crowd-reported 'this feels wrong' pins with auto-clustering so cities can see which intersections frustrate residents most
  • Weekly neighborhood digest showing average delay, red-light complaints, and how the AI has changed timing week-over-week
  • Plain-language summaries that residents can paste into city council meeting comments
Why now

Cities are quietly rolling out RL-driven signal controllers but face public backlash when timing changes feel arbitrary; an explainability layer aimed at residents turns a trust deficit into an adoption lever.

Demand
4/10

Public complaints about AI signal timing exist (Quebec case, smart-city backlash) but residents route feedback through 311 / SeeClickFix rather than seeking dedicated explainability apps; no evidence of organic consumer pull for a signal-decoding tool.Smart City: Building Trust Through Transparency - iAPPHere's how AI helped this Quebec town reduce its traffic

Whitespace
7/10

B2C layer of AI-traffic-signal explainability is unoccupied - Miovision, Surtrac, In|Sync and NeuroFlow all sell to cities/operators, not residents; no consumer-facing explainer found.Innovating Traffic Solutions for Smart Cities | MiovisionSurtrac: Real-Time Adaptive Traffic Signal Control - CMUGitHub - NeuroFlow

Monetization
3/10

Citizens rarely pay for civic apps - SeeClickFix and 311 tools monetize via municipal SaaS contracts, not consumers; selling 'AI explainability' to budget-constrained transportation departments is a long, hard sell with small per-city ACVs.SeeClickFix Pricing 2026 - pricingnowCivicPlus SeeClickFix 311 CRM

Longevity
8/10

RL/adaptive signal deployment is accelerating - In|Sync alone touches ~54M daily motorists and Surtrac/Surtrac-derived systems continue expanding into cities - so the explainability gap will persist for years.In|Sync - Rhythm Engineering

Feasibility
4/10

Hard to build without direct API access to proprietary signal controllers (SCATS/In|Sync/Surtrac are vendor-locked); requires city data-sharing agreements and a tactile plain-English model on top of phase/queue data.Innovating Traffic Solutions for Smart Cities | Miovision
