1. Core Technology

• Detection Data → Link Speed Data → DTN Analysis entire process to precisely implement actual traffic situations in a digital space

• Vehicle Re-ID** technology is utilized to supplement blind spots in detection, and speed estimation and connection analysis of undetected sections are possible

• AT-EVL (Any Time Every Vehicle Location) function is used to improve vehicle location estimation accuracy
• 3D map visualization enables intuitive traffic flow analysis and review of policy effects

   

2. Key Features

• Simulation verification possible before policy change through Signal Adjust Experiment**

• Quantitative comparative analysis of various policies through comparison between scenarios

• Enhance operational efficiency based on actual data with a comprehensive traffic analysis system

3. Signal Optimization

• Results of the demonstration on the 6.7km section of Dongtan-daero:

  • Reduced waiting time

  • Reduced frequency of signal outages

  • Optimization of offsets between intersections

4. Digital Twin Creation

• Precise matching of undetected road sections through vehicle re-identification

• Restoration of intermediate paths and movement patterns required for simulation

• Simulation of the effects of various policies without physical testing
