The Innovation of Natural Rubber Applied with Concrete Road Barriers in Thailand

The Development of Natural Rubber for Traffic Devices in Thailand has been researched in several years. The enormous budgets have also been invested for the increasing of rubber prices. One of Traffic Devices is the application of natural rubber sheets for the protection of motorists - driving motorcycles as crashed through concrete barriers. The number of road side accidents on rural roads in Thailand is about 3 fatality per 10 kilometers. Therefore, the 11.20 MTB per a Fatality of accident cost is evaluated to be 3,360 TB per km. This leads to the mitigation methods to remedy a symptom’s motorist from severity to moderate and mild respectively. The solution is to find the best practice of road barrier which is applied with natural rubber latex glued with concrete barrier. In addition, the composite materials will be calculated of the modulus of elasticity and properties such as, strength and durability. The simulation of crashes, finite element of materials, LRFD and Concrete Technology methods will be taken into consideration. The testing of material in Thailand will be firstly applied for these, for example the road crash testing under the standard of NCHRP – TL3 (100 kph) will be taken into account.

Speed Management

Cambodia has one of the highest road crash rates amongst low-and middle-income countries (LMICs), with speeding a major contributor. Best practice speed management has been promoted internationally, and transfer of knowledge and best practices from high income countries (HICs) to LMICs has been recommended. However there is a need to take account of the physical, social and political environment of the LMIC concerned. The aims of this study were to analyse the context of speed management in Cambodia using the Road Safety Space Model (RSSM), and to recommend how best practice speed management could be implemented. Secondary sources were reviewed, and semi-structured interviews were conducted with 13 key informants with professional experience in speed management and enforcement in Cambodia. The interviews were recorded, transcribed, translated and thematic analysis was undertaken. The findings were interpreted using RSSM, within the categories of economic, institutional and social/cultural factors. Although there are Cambodian government initiatives to address speeding issues, many challenges were revealed. Recommendations are made, aligned with best practice recommendations for speed management. They include establishment of a functional road hierarchy and a review of provisions for different road users; a move away from the current complex vehicle-based speed limit scheme; improved databases to support enforcement, monitoring and evaluation; a review of current legislation and practices around fines and implementation of the licence points system; improvement of the spatial and temporal coverage of enforcement; public education to support enforcement; workplace safety measures to address speeding; and better coordination and funding across government agencies.
