Area of Science:

  • Traffic Safety
  • Data Analysis
  • Public Policy

Background:

  • Police stations manage local road traffic accidents, a critical public safety concern.
  • Effective accident prevention requires policies tailored to local accident characteristics and driving environments.

Purpose of the Study:

  • To analyze local road traffic accident variations in relation to environmental characteristics.
  • To apply Quality Function Deployment (QFD) for prioritizing accident control policies for police stations.

Main Methods:

  • Cluster analysis was used to group accident data based on local characteristics.
  • Poisson regression modeled accident severity within identified clusters.
  • Quality Function Deployment (QFD) integrated analysis results to prioritize policy interventions.

Main Results:

  • The study identified distinct local accident patterns and their associated environmental factors.
  • QFD provided a framework for prioritizing road accident control policies based on data-driven insights.
  • Specific accident severity levels were linked to actionable control factors for police intervention.

Conclusions:

  • Tailoring prevention policies to local accident characteristics is crucial for effective road safety management.
  • QFD offers a systematic approach for police stations to prioritize and implement targeted accident reduction strategies.
  • Integrating statistical analysis with QFD enhances the efficacy of road traffic accident prevention efforts.
