The concept of building a friendly city for older people by adjusting the physical environment is considered one of the crucial components of promoting older people’s better health and quality of life. Based on this tenet, designing a suitable footpath and considering older people’s needs are vital to the reduction of risks and the increase of safety in travelling, especially for older people living in Wat-Thad and Wat-Klang communities where the proportion of the elderly has continuously, increased. The research aimed to 1) survey the physical environment of footpath, approaching public assistance, 2) observe the elderly’s behavior and satisfaction on footpath in communities, and 3) create the proposal concept in developing the suitable footpath with the elderly’s need in city area. This research used various tools, including the questionnaire on the footpath’s physical environment to analyse problems, limitations, and footpath potentials, the interview of staff in the Engineering Division, Khon Kaen municipality and the questionnaires collecting travelling behaviour, satisfaction and attitude of elderly on the footpath in community. The data analysis the physical environment following six components in the monitoring list showed three used descriptive statistics. Interestingly, from 370 samples, the results of investigating qualified evaluations, namely 1) land utilisation in the communities, 2) linking the transportation network, and 3) beautifully attractive places for walking. However, three unqualified evaluations were 1) safety footpath availability, 2) design for all people, and 3) walking on the footpath to access public assistance and facilities. Moreover, the results from the questionnaire to study older people’s travelling behaviour, indicated that the most travelling objectives were grocery shopping and accessing the recreation sites with frequent visits three to five times per week. Furthermore, older people’s satisfaction with the community footpath was overall at a high level, This research proposed suggestions for developing a safe footpath to ensure safe walking access to facilities and public assistance.

This project presents the development of a single-frequency GPS-based total electron content measurement tool. It applies theories related to total electron content in the ionospheric layer and the measurement of total electron content using GPS time delay to design the single-frequency GPS total electron content measurement tool. The tool consists of an antenna, a single-frequency GPS satellite receiver, a data processing unit for evaluating and calculating total electron content, and a display unit for showing total electron content data. The performance of the single-frequency GPS total electron content measurement tool is tested by comparing it with total electron content data obtained from the International Reference Ionosphere (IRI) model, which is a global reference model for electron content. The tool is also put to practical use. The results of the comparison and practical applications conclude that the single-frequency GPS-based total electron content measurement tool can be effectively utilized, with the difference from the IRI model being 50 TECU
