This project has been established to study and develop the rural community roadsafety tool kits emphasized on how to transfer the appropriate traffic engineering knowledge to safer the rural community road. In phase I, the speed management is focused. The project summary can be drawn as follow:
1. The project summarized the lessons learn from 3 case studies.
- Case study I, Kham Nang Poom Village road safety project presents the
community involvement in speed enforcement.
- Case study II, MSU Gateway presents the effectiveness of gateway treatments to reduce the vehicle speed passed through the campus.
- Case study III, Black spot improvement in the villages around MSU presents the possibility of community involvement in black spot treatments program as well as speed management program.
2. This project studies existing speed bumps and humps through the 3 methods; 1)questionnaire survey, 2) spot speed study, 3) on route vertical acceleration survey. The study results show that:
- The existing speed bumps, although have relatively low construction cost, cause excessive difficulty to the road user. It post unnecessary hazardous to road user especially when installed on the collector road. Key factors are from the speed differences between the motorcycle and passenger car when crossing the bumps.
- The motorcycle rider tends to use the higher speed to cross the wider bump and the higher speed tends to yield the higher vertical accelerations.
- Standard size of road hump recommended in the Western countries may not suitable to control the motorcycle speed.
3. This project develops the rural community speed management guidelines. It provides evidence of why speed management in the community road is important. It explains the basic knowledge about the speed and its impacts on traffic accident. To access
the speeding situation, speed study techniques are also discussed. Finally, speed control measures are addressed. It is hoped that the document can be read and easily adapted to suit the problems and needs of individual communities.
4. This project also develops the research team and the prototype communities in the 6 villages. The speed management training and workshops were organized to fill the technical knowledge and reveal the existing speed problems. Based on the findings, the
speed management programs were conducted. These include the improvement of existing speed bumps and construction of new speed humps. The programs were successfully implemented in the target villages as well as were effectively distributed to nearby areas. Several villages volunteer to construct the road hump on their local road from their own budget. Project results create significant changes both in terms of physical and knowledge.
The physical changes refer to the traffic calming devices from community action. The knowledge changes extend to the developed guideline and the knowledge gain by the research team members and community leaders who can develop their own skill to identify and analyze the speed problem. They also enable to lead other communities as well. It is hoped that to encourage the community to participate in improving their own safety problems, i.e., to create problems ownership feeling, to analyze their own problem, to seek for improvement solutions by integrating of local wisdom and technical knowledge, will enable sustainable community safety improvement.
