Lessons learnt from the aforementioned crisis drive us forwardly to face any future risks more effectively by technological and innovation improvement. We need to acquire any possible mechanical tools to ensure that the “Expressway riders” are the “Express persons” in any riding trip. Accordingly, from now on our organization’s vision of “Enhancing Expressway development for sustainable safety with fast and conveniency” will lead toward a more challenging one of “Being the innovation organization for better traveling and living” within 2023 through a rapid improvement of the traffic in front of the toll point based on M-flow under AI. This purpose shall be possible by available land using to enhance EXAT aims in various forms.

Expressway Authority of Thailand Human Resources Development The Expressway Authority of Thailand (EXAT) attaches importance to the development of the potential or capability of employees at all levels by formulating a human resource development action plan in line with the strategy of EXAT. EXAT has developed the performance of employees in each position according to Core Competency, Functional Competency, and Managerial Competency and Individual Development Plan (IDP). The new development roadmap aligns with the organization’s core competencies. In addition, it prepares personnel for the promotion and replacement of retirees, including supporting new missions by Reskill & Upskill for employees. In the fiscal year 2021, the annual human resource development action plan has been implemented in various essential areas as follows : 1) To develop knowledge, skills, and competencies of managers and personnel at all levels to have the potential to work professionally, adapt to the digital age, and be ready for change. 2) To develop personnel based on morality, ethics, and good governance. 3) To systematically and continuously enhance various root-learning processes and methods and promote the organizational culture. 4) To promote knowledge management within the organization and create innovation in operations. 5) To develop information technology systems to support personnel development and learning within the organization. 6) To develop personnel by creating work-life balance to improve the quality of life in employees’ work. In this regard, EXAT organized 41 training programs, seminars, and work tours for executives and employees. It does not include other courses that send employees to study and train with external agencies, both public and private, including encouraging employees to pursue higher education at both master’s and doctoral levels. During the Coronavirus Disease 2019 (COVID-19) epidemic, EXAT has changed the training format to be online by learning through an E-Learning system and virtual training classroom through the Zoom Cloud Meeting system, which makes the development performance personnel achieve the objectives according to the set goals. 30

ANNUAL REPORT 2021 Code of Conduct of the Expressway Authority of Thailand Code of Conduct is a code of ethics or code of etiquette for EXAT officers to maintain and promote members’ honor, reputation, and status and is a code of conduct used as a moral and ethical measure for EXAT staff. The word “ethics” can be divided into ethics + dharma. The word ethics means behavior or behavior that should be performed. In contrast, dharma has many meanings, such as virtue and principle. When the two terms are combined to form “ethics,” they mean “ethical conduct,” “Principles of Conduct” or “Guidelines of Conduct.” In this regard, EXAT has given the meaning of ethics as morals and guidelines for the conduct of EXAT officers with honesty, integrity, and fairness, both in treating the organization and all groups of stakeholders, as well as the public and society to achieve the ultimate goal of the organization to be the leading state enterprise in the country. However, it can be seen that “ethics” or “conduct” have the same goal : to want each person or various organizations to have good practices and behaviors or good behavior towards oneself and others. It’s a matter of reason and discretion. It also creates a high level of mental awareness of the individual. EXAT is an agency whose primary mission is to solve traffic problems in Bangkok and its vicinity with various transport lines, leading to the development of the logistics system in the country. It is responsible for managing the special rails of Thailand by focusing on management with good governance. Therefore, it is determined to create significant awareness about ethical work in EXAT; and it is meant to be recognized and trusted by stakeholders and the public. The approach to raising awareness must be carried out with a commitment to achieve results among all EXAT staff, with stakeholders, service users, and people who can perceive and feel the outstanding characteristics of EXAT personnel. EXAT has adopted the organization’s ethical standards, which are core values of EXAT, which have been recorded since the fiscal year 2011, using words that denote the internal commitment of EXAT officers to perform their duties as EXAT officers with ethics. They also have followed the guidelines that the organization has given seriously as the abbreviation that conveys the determination of EXAT officers as “HEARTS,” which means “do your duty with the heart.” HEARTS Determination to “work with one’s heart” comprises of the following principles which shall be holding by all working staff. H E A R T S Honesty TErEqequauittmiatybe/lnet Accuracy Responsibility Transparency Society Accuracy, Honesty, Equity, Responsibility, Transparency, Society Thereby, EXAT recompiles its Code of Conduct for the modern era requirement approved by the EXAT Board in the 11/2021 meeting organized on 23 September 2021. 31

Expressway Authority of Thailand Guidelines for Enhancing Corporate Governance in the Expressway Authority of Thailand Good Corporate Governance Policy The main aim of EXAT in operation is to alleviate traffic congestion in Bangkok and its vicinity to reduce the country’s economic losses and ensure financial stability and sustainable growth.
