Design And Development of an Online Electronic Directory System for Tagbilaran city with A* Algorithm Edgar Uy II, MEng

ABSTRACT Tagbilaran City is the capital of Bohol. Bohol now is well known for its many tourist destination. Usually all travelers who wants to explore Bohol first starts in Tagbilaran City since the main port is located in it. In arriving to a new place one of the problems commonly encountered is finding for an establishment on where to stay and the route towards that particular establishment. Although a paper map provides information of a particular place it does not give us all the necessary information we are looking for a particular establishment nor does it show the image of an establishment.

The paper map does not also show the shortest path towards an establishment. It is on these problems that the proponent decides to develop a system that helps tourists visiting Tagbilaran City to find for establishments and gives the shortest path towards the establishment.

Goals and Objectives of the Study The main objective of this study is to create an online directory of Tagbilaran City using A* algorithm as its main search algorithm in finding establishments. This study aims to accomplish these objectives: 1.To find important establishments located in the city that are vital to their stay in Tagbilaran City. 2.To find reliable and accurate information of a particular establishment. 3.To travel without the hassle of looking at a printed map and frequently asking people for directions and information.

Statement of the Problem One of the main problems encountered by a traveler when arriving in Tagbilaran City is finding establishments and information about it. This research project aims towards the solution to this problem. This study aims to answer the following questions: 1.How to find accurate or reliable information on a specific place or establishment? 2.What does that particular establishment look like? 3.What is the shortest path towards this establishment?

Conceptual Framework

The system with its graphical user interface (GUI) interacts with the web server and the SQL Server. The system displays a road map on the screen. A zoom option allows the user to look closely on the road map. The user then chooses on the menu buttons and click on it. Markers then appear on the road map to indicate the location of different establishments that belongs to the specific category. The user then clicks on a marker of his/her choice and a picture of that establishment is then displayed and all the necessary information is then displayed. These information are the address, contact number, business hours and distance from the port.

A user can also use the search menu options and type the name of an establishment and then a marker will appear on the road map indicating the location. The user can then click on the marker and view a picture of the establishment and all important information related on that establishment are displayed. The system also identifies the nearest type of establishment a traveler/tourist may want to visit. A search field is provided for the user to input the desired establishment he/she wants to visit.

CONCLUSION The Online Electronic Directory System of Tagbilaran City with A* algorithm indeed provides another way of traveling in Tagbilaran City without the use of the conventional paper map. It is better than the paper map since the system not only displays the road map details but also the image of an establishment and the basic information. The image can be viewed by clicking the hover on the map. The location of the hover on the map is also the actual location of the establishment. This system is unique since it also determines the shortest path towards an establishment. This functionality is attributed to the A* path finding algorithm which gave a 100 % accuracy. This allows a tourist to gain sight of the path towards that establishment.

RECOMMENDATIONS There are a lot of things that have been considered in doing this project like correctness, user friendliness and algorithms. The core study of the researcher is the implementation of the A * algorithm. The researcher just considers it appropriate that whoever would think of implementing a new version of this project, the following recommendations shall be employed: 1. Create a GUI that is more pleasing to the users. 2.Update map information and details on establishment. 3.Develop more functionality of the system aside from the shortest path and nearest establishment functionality such as traffic updates and other possible routes towards the establishment. 4.Create more functionality on the administrator side such as add map and traffic update.
