DEVELOPMENT OF EQUIPMENT POSITIONNING SYSTEM OF THE EXPRESSWAY NETWORK USING MOBILE APPLICATION

Abstract

The total length of expressway network in Bangkok area is about 224.6 kilometers. There are many components of expressway structure and equipment for controlling and facilitating along the network. Therefore, GIS-based asset management system by ArcGIS has been established which specifies the location, related information, and pictures of the equipment. However, the process of collecting and recording all those data is quite difficult especially in the high-speed traffic conditions which may cause accidents during the data survey process. Thus, the mobile phone application “Theodolite” has been adapted to achieve the task. Equipment location data that is; “pictures and location” taken by the application and “distance” measured by Electronics Distance Measurement (EDM) are encrypted then sent via email. In this process, the PHP script is written to extract and calculate the encrypted data. Then, all extracted information will be inserted the database. In doing so, a number of targeted equipment can be surveyed faster, safer, and more convenient.
