スマートシティ交通デジタルツイン＆V2Xインフラストラクチャ
MobilityTwins は都市の幹線道路や交差点をリアルタイムの微視的交通デジタルツインに再現します。路側センサー統合、C-V2X協調認識メッセージ、適応型信号制御を連携させ、死角をゼロにし自動運転車群を都市規模で統合制御します。
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
自動運転車に見通し外の道路認識能力を付与する
ソフトウェア定義モビリティでは、路側センサー基盤と車両の軌道計画系とのクローズドループ化が不可欠です。MobilityTwins は路側LiDARやカメラの検出情報をETSI準拠の協調認識メッセージ（CPM）に変換し、適応型信号制御と低遅延危険通知（20ms以下）を実現します。
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.
