DEVELOPMENT OF A ROAD SAFETY MANAGEMENT MODEL USING THE DISTRICT QUALITY OF LIFE DEVELOPMENT COMMITTEE (DQDC) MECHANISM TO DRIVE MULTISECTORAL NETWORK PARTICIPATION IN PHAYUHA KHIRI DISTRICT, NAKHON SAWAN PROVINCE

Abstract

This participatory action research aimed to develop a road safety management model using the District Quality of Life Development Committee (DQDC) mechanism to drive multisectoral participation and to examine the effects of implementing the model in Phayuha Khiri District, Nakhon Sawan Province. The research was conducted based on the action research framework of Kemmis and McTaggart, comprising four stages: planning, action, observation, and reflection. The model development group consisted of 21 members of the District Quality of Life Development Committee, a sample of 385 representing community network partners participated in the evaluation. Research instruments included a road safety management model effectiveness assessment based on the CIPP model, a network participation measurement scale, focus group discussion guides, and road traffic injury data retrieved from the Health Data Center (HDC). Quantitative data were analyzed using descriptive statistics and paired-sample t-tests, while qualitative data were analyzed using content analysis. The results indicated that the developed road safety management model was a systematic and participatory model consisting of six key components: 1) Defining Roles and Responsibilities 2) Establishing Network Partnership Engagement Teams 3) Defining Safe Driving Measures 4) Raising Awareness and Enhancing Road Safety within the Community 5) Managing Road Accident Risk Spots in the Community 6. Developing Data Management Systems. The overall effectiveness of the model was rated at a good level (Mean = 3.80, SD = 0.34). Furthermore, comparisons of network participation levels before and after model implementation revealed statistically significant improvements across all dimensions (p < .05). In conclusion, the road safety management model driven by the District Quality of Life Development Committee mechanism effectively strengthened systematic road safety management, enhanced multisectoral participation, and supported sustainable road traffic injury prevention and reduction at the district level. The model can be adapted and applied to other districts with similar contextual characteristics.
