The Traffic Performance Index (TPI) serves as a key indicator to evaluate the efficiency and flow of traffic within urban areas. It combines various metrics to assess congestion levels, travel times, and overall network performance. This index allows transportation planners to identify problematic areas and prioritize improvements based on real-time data and predictive modeling.

The TPI is constructed using several factors that reflect the status of traffic conditions:

  • Travel speed
  • Travel time reliability
  • Congestion levels
  • Vehicle density
  • Incident occurrences

Key Insight: By tracking these elements, cities can manage resources more effectively and improve commuter experience.

The formula for calculating TPI includes the weighted combination of these factors, allowing for a clear comparison between different areas or time periods. The following table shows a simplified version of how various metrics contribute to the overall TPI score:

Factor Weight Impact on TPI
Travel Speed 0.4 High
Congestion Level 0.3 Moderate
Incident Frequency 0.2 Low
Vehicle Density 0.1 Low
