Challenges and Innovations in Urban Traffic Safety

Addressing Risks in Non-Crosswalk Zones

With rising urban population density and traffic volume, pedestrian safety in non-crosswalk areas has become a global challenge. Data from the Governors Highway Safety Association reveals that U.S. pedestrian fatalities in traffic accidents exceeded 7,500 in 2022—a 40-year peak. ‌Unmarked crossings, low nighttime visibility, and adverse weather conditions‌ remain the three core risk factors. Ouster Blue City tackles these challenges by integrating LiDAR perception systems with AI analytics, delivering real-time risk alerts and data-driven insights for urban planners.

Core Technology Architecture of Ouster Blue City

Full-Scene LiDAR Perception System

Powered by Ouster’s high-resolution digital LiDAR technology, the system constructs ‌centimeter-accurate 3D digital twins‌ for high-risk zones like intersections and highway ramps. It dynamically tracks pedestrians, vehicles, and micromobility devices across all lighting and weather conditions.

Multi-Layered Safety Framework：

1.Dynamic Zone Configuration‌

Customizable virtual monitoring areas (e.g., non-crosswalk exclusion zones) via an intuitive interface

Supports multi-zone overlay analysis for complex road networks

2.Intelligent Behavior Recognition‌

Detects 11 types of high-risk behaviors, including jaywalking,逆行, and red-light violations

Anonymous tracking with unique IDs to map behavioral hotspots and peak hours

3.Hierarchical Response System‌

Tier 1: Activates on-site warning lights/V2X broadcasts

Tier 2: Syncs event logs and generates heatmaps in the cloud

Tier 3: Provides traffic flow optimization recommendations (e.g., barrier installation, signal timing adjustments)

Data-Driven Safety Decision Platform

Multi-Dimensional Analytics Dashboard：

Real-Time Risk Mapping‌: Live geographic distribution of active incidents

Historical Pattern Analysis‌: Hourly/weekly/monthly accident trend breakdowns

Infrastructure Efficacy Evaluation‌: Pre/post-intervention violation rate comparisons

Building a V2X-Ready Ecosystem

Pioneering Vehicle-to-Everything Integration

As the perception layer core for V2X systems, Ouster Blue City enables:

Real-Time Data Sharing‌: Encrypted pedestrian location feeds to connected vehicles

Dual-Mode Compatibility‌: Supports both DSRC and C-V2X communication protocols

Future-Proof Scalability‌: Pre-configured modules for autonomous vehicle collision avoidance

Through its layered architecture and closed-loop data ecosystem, Ouster Blue City redefines smart mobility safety standards—from real-time alerts to sustainable urban planning—for a more human-centric transportation future.
