Development Of a Control System For Barricades And Traffic Lights For Crossing Roads With Internet Of Things (IoT) Technology: Case Studies On Elementary Or Secondary Schools In Khon Kaen Municipality

Abstract

This study has three objectives which are 1) to develop a control system for barricades and traffic lights for crossing roads using the Internet of Things technology; 2) to assess the efficiency of the control system for the barriers and traffic lights for crossing roads using the Internet of Things technology and; 3) to compare the efficiency between the original road-crossing traffic light system and the barrier control system along with the road-crossing traffic light using the Internet of Things technology. The researcher had invented a barrier device and a traffic light that worked with Board We Mos D1 via the Internet to NETPIE2020 and could be commanded through Web Application developed with PHP language and Bootstrap Framework. We employed the efficiency and satisfaction evaluation form as research tools to collect data from the total population sample of 100 people for the study. Purposive sampling method was used, and the population samples were divided into 3 groups as follows: 1) 5 IT professionals; 2) 5 personnels or relevant personnels and; 3) a group of 90 people who cross the road. The statistics used to analyze the data were percentage, mean, and standard deviation. The following results showed the efficiency of the system in all 4 areas: 1) For functional requirement test, the overall average of efficiency was good (  = 3.95) 2) For function test, the overall average of efficiency was good (  = 3.94) 3) For usability test, the overall average of efficiency was good (  = 3.84) and 4) security test, the overall average of efficiency was good (  = 3.96). The following were results of satisfaction evaluation with the system in all 3 areas: 1) For suitability for use, the total mean of the satisfaction with the system was at a high level (  = 4.06) 2) For the functioning of the system, the total mean of satisfaction with the system was at a high level (  = 4.01) and 3) For safety, the total mean of satisfaction was at a high level (  = 4.04). According to the findings of the research on the system's efficiency and satisfaction, the efficiency was good and it could function as efficiently as the original road-crossing traffic light system.
