Toyota Mobility Foundation's "Tateshina Conference" Overseas Subcommittee Holds Workshop in Bangkok, Thailand, on Implementing Traffic Safety Measures

The Toyota Mobility Foundation (TMF) (Chairman: Akio Toyoda) held a workshop on July 3, 2026 (Fri) in Bangkok, bringing together key organizations involved in traffic safety. This event was part of "TRUST (Thailand Road Users Safety through Technology)" (※2), a traffic safety project promoted by the overseas subcommittee of the "Tateshina Conference" (※1), an initiative aiming to eliminate traffic accident fatalities and injuries beyond corporate boundaries.

At the workshop, participants shared their understanding of issues based on an analysis of accident-prone locations in the Chatuchak district and discussed concrete directions for traffic safety measures.

TRUST is a collaborative project involving TMF, the Bangkok Metropolitan Administration, UN-Habitat, the Asian Institute of Technology, Toyota Motor Thailand, and Road Accident Victims Protection Co., Ltd. It aims to identify risks and dangerous behaviors that lead to serious accidents by combining AI analysis utilizing diverse data such as vehicle probe data and CCTV footage, systematic data collection, and the identification of near-miss incidents and dangerous driving behaviors, thereby leading to highly effective traffic safety measures.

Participants in the workshop included representatives from the Bangkok Metropolitan Administration, the Department of Disaster Prevention and Mitigation, the Office of Policy and Planning for Transport, the Land Transport Department, the Police, the Chatuchak District Office, private companies, and related organizations. Participants verified the analysis results, organized the issues, prioritized measures, and confirmed the direction for future implementation.

1. Background

Traffic accidents remain a serious social issue in Thailand, with motorcycle users and pedestrians being particularly affected in densely populated urban areas like Bangkok. While various initiatives have been undertaken, further improvements in traffic safety require data-driven analysis of accident causes and the promotion of effective measures through collaboration among relevant organizations.

2. Workshop Content

(1) Focused Analysis of Accident-Prone Locations

Based on accident occurrence and road environment characteristics in the Chatuchak district, the TRUST project selected the following three locations for focused analysis:

G2: In front of Wat Samian Nari School, under the railway overpass

G4: Ratchada-Lapphrao major intersection

G5: Ratchada Soi 32, main road merging point

For the analysis, CCTV footage, drone footage, and AI analysis tools (from companies such as DataFromSky and Transoft Solutions) were used in combination, tailored to the characteristics of each location. This allowed for the visualization of vehicle and pedestrian movement data and the analysis of traffic intersection patterns and the occurrence of dangerous behaviors, thereby identifying the causes of accidents at each location.

Identifying the root causes of accidents through data analysis tailored to the characteristics of accident-prone locations

In addition to traditional accident records, near-miss analysis using Time to Collision (TTC) was incorporated to identify potential risks that are difficult to grasp through normal on-site observation or accident records alone. This enabled quantitative analysis of frequency, time of day, and behavioral patterns, allowing for the prioritization of risks.

(2) Key Analysis Results

The analysis revealed different risk factors at each accident-prone location. For example, at G5 (main road merging point), vehicle interactions at the merging and diverging sections were identified as the primary risk. Specifically, it was found that improper lane changes to avoid congestion created a significant collision risk between straight-moving vehicles and turning vehicles.

Furthermore, combining AI analysis with on-site observations confirmed that the relationship between dangerous driving behaviors and road/infrastructure conditions could be visualized, leading to a clearer understanding of the root causes of accidents.

(3) Consideration of Measures Based on Analysis Results

Based on the analysis results, measures were discussed from the following three perspectives:

- Road and Infrastructure Measures (e.g., improvement of road markings, enhancement of visibility, redesign of traffic flow, deceleration measures, etc.)

- Human and Behavioral Measures (e.g., traffic safety awareness campaigns, driver education, traffic enforcement)

- Vehicle Measures (e.g., understanding driving behavior using vehicle probe data, etc.)

At the workshop, the direction of measures was organized from short-, medium-, and long-term perspectives. Through group discussions using large maps and prioritization exercises, the priority and implementation direction of measures were clarified. Additionally, representatives from relevant organizations and local stakeholders participated, discussing highly effective measures while considering local conditions and consistency with existing policies.

3. Future Developments

This workshop served as an important opportunity to strengthen collaboration among relevant organizations for the promotion of traffic safety measures in Bangkok. Based on the analysis results, the direction of priority measures tailored to local conditions was shared, and the roles of each organization and future approaches were organized.

Furthermore, participants from the KUB-DEE-DAI-DEE project (※3) also attended, creating a forum for sharing knowledge that connects traffic safety with awareness activities.

The TRUST project will continue to contribute to the realization of a safer, more inclusive, and sustainable mobility society by linking data-based analysis to concrete measures and through collaboration with stakeholders.
