INTRODUCTION:Philippines is an archipelago and mostly has mountainous

terrains. Due to that, transportation in the Philippines is relatively undeveloped.

In Tagbilaran City, most people rely on tricycles.

Problem:

Overcharged fares for passengers

Solution:

Advanced Digital Fare Meter for Tricycles

STATEMENT OF THE PROBLEM:The normal rate for tricycles in Tagbilaran City is eight pesos for

the first 1 km and additional 50 cents for every succeeding 500 meters, so getting around the city shouldn't cost you more than 50 pesos. So we picked 3 main problems:

Abusive Tricycle Drivers

Overpriced Fare

Demanding Passengers

OBJECTIVES OF THE STUDY:The researchers' objective of the study is to be able to make fare

meter for tricycles that can compute the amount due to the passengers which corresponds to distance travelled. It is composed of:

A GPS

An odometer

A microcontroller

An LCD

Push buttons

More specifically, the research aims to:

Set parameters & techniques

Come up with a system prototype

Come up with a fare rate

SCOPE AND LIMITATIONS: This project is designed for tricycles operating within Tagbilaran City.

The project is intended for the use of only two passengers.

The project is not intended to change the fare rate mandated by the Sangguniang Panglungsod of Tagbilaran City.

The GPS will sometimes lag causing the system to slow down and give inaccurate results.

Tricycles that would practice cheating like putting two or more magnets on the wheel.

PROJECT DESCRIPTION:1. GPS(Global Positioning System) receiver module A space based satellite navigation system Calculate geographical positions, accurate to a matter of meters

How It Works

2. Odometer it indicates distance traveled by a vehicle3. Microcontroller it can be interfaced with other devices temporarily stores data can do math computations4. LCD able to display characters can be interfaced with microcontrollers5. Push button can be used as switch

METHOLODOGY

INTRODUCTION:• These are the Magnetic Reed switch and the GPS module that is

responsible for the data which is computed by the Arduino.• The Arduino has the most user friendly interface for programming

prototype microcontrollers which gives the advantage of easy programming, debugging and testing of the program.

• In order for the system to detect if a passenger has rode the tricycle, a push button is set up to wait for input of passengers, in order for the system to start computing the fare.

• For the system to continue the interaction between human and system, the data computed by Arduino is then displayed on the LCD in order for the driver and passenger to clearly see and understand the data from the Arduino.

Pin to Pin Configuration

Result and Discussions:• The System is composed of the following components such as GPS

module for time and location, Magnetic Reed for switching and use for calculating the distance.• System attributes are observed and properly working such as

displaying the right value or amount, correct time and location and distance computation.• To get the distance travel (Dt) by the vehicles the number of rotation

(R) that the reed switch reads times the circumference (C) of the wheel represented by a formula Dt = R x C.• The GPS message makes the microcontroller takes noticeable time

to decode the messages and causes the system to malfunction and give inaccurate distance traveled.

• Another advantage of the system is that we used affordable yet efficient components in building it, therefore we can guarantee the drivers that they can afford to buy this system as well as providing them with better, working, and effective device.

• The GPS also takes time to lock on to satellites due to some reasons: the GPS must lock on to at least four different satellites before it can achieve 3D lock and start tracking your position and maybe the GPS is positioned to areas with obstructions, like traveling under trees, tall buildings, and other reflecting and signal blocking signals.

Conclusion:

Recommendation:• The tricycle fare meter practically achieved the objectives that were

envisioned by the researchers, still recommendations should be made in order to increase its reliability, stability, and efficiency as well as open new doors for further development.

• The researchers used one microcontroller in controlling the GPS and the magnetic reed as the odometer in tricycle fare meter.

• Lastly, the proposed fare meter is specially designed for tricycle in Tagbilaran only but it can be developed to be compatible with other vehicles.
