Smart City Mobility Digital Twin & V2X Infrastructure
MobilityTwins mirrors metropolitan road corridors and smart intersections into a real-time microscopic traffic digital twin. By orchestrating roadside sensor fusion, C-V2X collective perception, and actuated traffic control, the platform eliminates blind zones and coordinates autonomous fleets at urban scale.
Mobility Twins Engine Zonal Architecture
Central Controller: Mobility Twins Engine — Urban Spatial Graph Platform
Zonal Control Units & TSN Ring
- Roadside LiDAR / Radar Sensor Ingress
- Dynamic SPaT Traffic Signal Controller
- V2X Collective Perception Message (CPM) Broker
- Zonal Micro-Geofencing Policy Authority
- Emergency Vehicle Preemption Dispatcher
Giving Autonomous Vehicles Beyond-Line-of-Sight Road Perception
Modern software-defined mobility requires closing the loop between edge sensor infrastructure and vehicle trajectory planners. MobilityTwins translates raw road lidar and camera detections into ETSI-compliant collective perception messages, driving adaptive traffic light cycles and streaming localized dynamic hazard zones to vehicles with sub-20ms latency.
Core Engineering Areas
- V2X Collective Perception (CPM) — Aggregating pole-mounted LiDAR and radar detections at intersections and broadcasting standardized ETSI CPM frames over 5.9 GHz C-V2X sidelink.
- Dynamic SPaT Signal Optimization — Broadcasting real-time Signal Phase and Timing (SPaT) messages allowing connected vehicles to adjust speeds to coast through green lights without stopping.
- Dynamic Urban Geofencing Enforcement — Enforcing active operational constraints: slowing autonomous vehicles through school zones during dismissal, or barring transit from construction zones.
