Recognizing the urgent needs of accident knowledge and research, the Thailand Road Safety Master Plan, among others, identified the need for establishing a Thailand Accident Research Center (TARC) as a priority in its long-term action plan. Furthermore, the Master Plan made a strong recommendation that the best results of the research are achieved when it is carried out in an academic community, such as an university or a research institute and if possible, independent of the authorities responsible for implementing road safety measures. Another important point is that research is a long term and learning process. It is therefore preferably combined with education and training to transfer the knowledge gained by research to new generations of students. Thailand Accident Research Center (TARC) officially saw the light of reality in 2002 when the center was opened by King Carl XIV Gustav of Sweden.

Vision and Mission

The Center is envisioned as the research center to study the data related to accidents and other constraints for road safety improvement in Thailand
The Center Mission can be understood as

  • Increased efficiency in road safety work through increased expertise and understanding about why road accidents happen in Thailand.
  • To find innovative and yet, pragmatic solutions to avoid accidents and improve road safety in general, through high-standard research, application, evaluation and dissemination of practices on the partnership basis.

Focus Areas

The Thailand Accident Research Center (TARC) focuses on various aspects of road safety in the Thai context, including accident investigation, reconstruction, road safety audit, and research activities aimed at analyzing, evaluating, and acquiring knowledge to enhance road safety. TARC’s objectives include studying contributing factors to accidents, evaluating the effectiveness of safety programs, and conducting in-depth analysis of road crashes, particularly in areas such as car-following driving simulations and construction project safety.

Featured Projects

In-depth motorcycle accident investigation project (Motorcycle Accident Investigation: Year 2016-2020)

The objective of this project is 

The outcome of this project will enable the related agencies working in road safety to develop countermeasures to increase active safety to prevent or reduce the occurrences of motorcycle crashes or passive safety to reduce severity of motorcycle accidents.  In addition, the outcome of this project will be applied to the safety driving training program and approach to the governmental entities to increase the safety awareness in the public.

Toyota Passenger Car Accident Analysis (2018-2023)

The objective of this project is to conduct the in-depth Toyota passenger-car accident investigation (AI) by using the Event Data Recorder (EDR). EDR is the recording system located in airbag ECU for diagnosis.  In case of a crash with airbag deployment, it records a few seconds of a vehicle’s operation immediately before and after the crash.  EDR collects data from on-board computers, including acceleration, velocity, seatbelt status (for driver), brake pedal and acceleration pedal condition, and airbag deployment information.  The data recorded by EDR will be used for further analysis in the in-depth accident investigation process to understand the causes of crashes.  The output of this project will be the new approach to conduct in-depth accident investigation by using the EDR technology and to analyze accident data by including driving maneuver information and vehicle performance at the time of crash.  The information from EDR will be very important to analyze the root causes of crash and to understand how the crashes occur.

Road Assessment Program in Lao (02/2023-08/2023)

The main objectives of project are the preparation of intermediate post-construction iRAP survey. The purpose of the iRAP assessment is to identify areas of concern for the safety of the travelling public from selected road infrastructure. The recommendations arising out of the iRAP Star rating will inform the Client on road infrastructure to mitigate the hazards identified.
