Use your HERE Traffic API key with SignalGuard to upgrade the traffic signal with HERE's incident and flow coverage — a drop-in for enterprise mobility customers who already license HERE for fleet, navigation, or city analytics.
What HERE Traffic adds to SignalGuard
The traffic signal sits in SignalGuard's Movement pillar. Default coverage runs through a TomTom integration; HERE Traffic offers a parallel premium feed with different sensor coverage, incident classification, and flow segmentation. For venues in markets where HERE has stronger sensor density — particularly Europe and several large North American metros — the BYOK path improves both incident recency and false-positive rates.
Inside the 50+-signal model, traffic feeds the venue-level threat score by quantifying ingress corridor risk. A road-closure incident on a primary access route raises the traffic severity, which then weights into operational decisions about gate-hold timing, security perimeter placement, and emergency-route viability.
HERE's flow data also lets SignalGuard reason about congestion trends pre-event — useful for predicting when crowd arrival pulses will compress against limited entry points.
How the integration works
Paste your HERE API key into the HERE Traffic tile at /integrations. SignalGuard validates it with a low-cost flow call, then stores it AES-256-GCM encrypted at rest. All HERE requests run server-side.
Common use cases
- Ingress and egress corridor monitoring for stadiums and arenas
- Festival site access road incident detection across long windows
- Marathon, parade, and street-closure route monitoring
- VIP motorcade route risk briefings against live incident data
- Cross-checking TomTom default coverage where HERE sensor density is higher
- City-wide event coordination for venues sharing access infrastructure
What you need
A HERE developer account at developer.here.com. The free tier covers 250K transactions/month; Pro plans start at $99/mo, with enterprise contracts available for high-volume traffic use cases. Generate a REST API Key from your project page.
FAQ
Do I need a HERE subscription? No — the traffic signal works through the default TomTom path. HERE upgrades it where you want broader or alternate sensor coverage.
Where do I add my key? In your SignalGuard workspace at /integrations. Open the HERE Traffic tile and paste your API key.
Is my key secure? Yes. Keys are AES-256-GCM encrypted at rest and never appear in browser-side code, logs, or telemetry.
