The expressway is the infrastructure. Not just the asphalt.
Spondbyte builds connected corridor infrastructure for NHAI, NHIDCL, state highway authorities, and concessionaires. V2I communication, variable digital signage, EV charging grids, multi-utility poles, and automated enforcement — on a single integrated stack.

What highway authorities face today
Every pole is a single-purpose asset
Lighting poles, camera poles, sensor poles — each procured separately, each with its own maintenance contract, none sharing data
EV corridors exist only on paper
Charger availability, health status, and load balancing have no integration with the highway command centre
Signage is manual or static
VMS boards updated by phone call. No automated response to fog, incidents, congestion, or lane closures
Outcomes
Fewer fatalities
Wrong-way detection in under 50 ms. Fog advisories pushed to every vehicle within 300 m. Automated incident escalation.
Faster incident clearance
Real-time detection and dispatch. Target clearance under 12 minutes from first alert to lane reopening.
Higher compliance revenue
Automated challans with end-to-end loop closure under 30 seconds. Court-admissible evidence.
What we deploy
Connected corridor infrastructure
Every pole, sign, and charging point — one network.
Modern expressways are not just roads — they are linear utility corridors. Spondbyte deploys connected infrastructure that turns passive hardware into an intelligent, responsive network. Variable message signs that react to real-time conditions. EV charging stations reporting availability and health. Multi-utility poles combining lighting, sensing, communication, and surveillance on a single mast.
All managed from the same command layer that runs your ATMS. No separate vendor dashboards. No fragmented telemetry.
Variable digital signage
Content management, real-time speed/weather/incident updates, remote scheduling, brightness auto-adjust
EV charging grid
Charger health monitoring, availability API, load balancing, payment integration, fleet reservation
Multi-utility poles
Lighting + camera + RSU + AQM + 5G small cell on one mast. Shared power, shared backhaul, single maintenance contract
Smart tolling integration
FASTag analytics, lane throughput monitoring, revenue reconciliation, queue detection and dynamic lane allocation
Corridor connectivity
Fibre backbone health, cellular failover, V2I mesh status, edge compute node uptime — all on one dashboard
Structural health
Bridge load sensors, pavement condition scoring, guardrail impact detection, overpass deflection monitoring
Asset analytics
Lifecycle tracking, energy consumption, utilisation rates, predictive replacement scheduling across all corridor assets

How we work
Scoping
Corridor survey, traffic data analysis, DPR alignment. Output: scope document with BOQ.
Design
System architecture, pole placement, integration plan. Output: DPR-ready design with compliance matrix.
Deploy
Hardware installation, fibre/cellular backhaul, commissioning. Factory + site acceptance testing.
Operate
AMC, remote monitoring, OTA updates, quarterly review. SLA-backed uptime with 24/7 NOC.
We work with NHAI, state PWDs, and expressway concessionaires under standard EPC and BOOT contract structures. Compliance pack available on request.
