RS-19-13  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Remote Sensing and Geographic Information System  aThesis (M. Sc.) - Asian Institute of Technology, 2019  aCurrently, many people may accustom and may use the technology to position themselves,  which the technology that has the ability to position this accurately is called GPS. GPS is  used in many applications, one of them is tracking vehicles. GPS tracking devices for vehicle  car are used in the various consumer because GPS trackers can help to operation and  inspection without a field survey. The use of GPS in public transport systems is interesting,  which one of the most popular public transport services today is taxis. In the present, GPS is  used to track and monitor the driving behavior of taxi drivers widely because taxi drivers  have different driving behavior, both normal driving, and unsafe driving behavior. Thus, it  useful to improve taxi service.  Therefore, this thesis work aimed to study about driving behavior of taxi driver that  passenger encountered and use the GPS receivers to detect the driving behavior of taxi  driver. In this study, many devices were used to test the ability to collect the GPS signals,  and monitor the driving behavior. There are three objectives in this study which are; 1) to  study the driving behavior of taxi driver using questionnaire survey, 2) to field test the GPS  receivers, and 3) to assess the accuracy of the data obtained from GPS receivers. From these  objectives, this thesis makes the criteria to detect unsafe driving behavior. Moreover, this  study will show the driving behavior that passenger feel unsafe which are Over the speed  limit, Sudden lane change and Sudden braking, and show the accuracy value and issues when  collect the data in field survey in each device. Finally, this thesis show the percentage of  accuracy of each device for detecting unsafe driving behavior which JA V AD GNSS is the  best device to detect driving behavior of driver.     0aGlobal Positioning SystemxData processing 0aMotor vehicle driving 0aMobile apps1 aTripathi, Nitin Kumar,eChairperson0 aApichon Witayangkurn,eCo-Chairperson0 aSurachet Pravinvongvuth,eExamination Committee 0 aSaksin Chongolnee,eExamination Committee 2 aRoyal Thai Government Fellowship,eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
