Introduction

In our generation today, bicycling is one of the essential form of transportation. Bicycle is an eco-friendly vehicle that doesn’t emits anything that may harm the environment. The activity of bicycling help to develop our physical body, enhances our sense of sight and hearing. It saves cyclists in heavy traffic by passing through narrow spaces. As the traffic and number of large vehicles are getting tough, any people was about to choose cycling rather than to drive any vehicle. Among all advantages get form cycling, there is a problem encounter by many of the cyclists. Many of drivers are not aware for some of the cyclists who can’t give a hand signal if they are about to turn, which averts a possible collision and misunderstanding between vehicles. One of the reasons why there are cyclists who get through accident. Turn signal actuators are indispensable piece of devices for every vehicle that can be also applied in bicycle. The device is particularly used for switching or flashing the side indicator lights (left or right) of a bicycle while making a turn or a deviation from its normal path. Basically the flashing of the LED acts like a warning signal and makes it easier for the other vehicles to identify the track of the indicating vehicle. This averts a possible collision and misunderstanding between vehicles. The device thus specifically helps in avoiding accidents and mishaps. Accompanied with an audio indication like a buzzer or a beeper which may produce a rhythmic note with the light switching. This facility proves to be useful in two ways, first: it assures the driver regarding the perfect working of the entire system and second: when the necessary deviating move or a turn is completed, the audio note keeps reminding the driver that the unit is still ON and needs to be switched off, thus saving precious battery power and false indications.

COLLEGE OF ENGINEERING Statement of the Problem This project is focused on designing and developing a system that can be applied on ordinary bicycle. It gives low-cost simple signal blinkers that can provide a very useful accessory to your bicycle. This project aims to answer the questions: 1) How can a device be developed in a way that identifies when bicycle turns? 2) What enhancement can be further made to an ordinary bicycle to provide convenience in its usage? 3) How can this device helps the bicycles user eliminates the need of giving hand signals?

Objectives of the Study Aims to develop a device that will notify other motorists. The main objectives of the study are as follows: 1. To develop a device that can notify motorists that the bicycle will turn. 2. To reduce bicycle accident in the road. 3. To help bicycle users, giving an alternative low-cost simple solid state signal blinker. 4. To make an easier way of giving signals by developing a “one click” turning indicator instead of hand signal of the cyclist.

Conceptual Framework

INPUT Pressing the SPDT switch onto the side with respect to what side you’ll track.

PROCESS As switch was pressed in right, the electron from the battery flows to the conducting circuit through the positive connections of both LED lights on the right side with the beeper connected to it which causes continuity of current flow through that path.

OUTPUT The LED lights with respect to what side you’ve pressed the switch will produce a blinking light and the buzzer connected to it will simultaneously produce a beeping sound with respect from the blinking rate of light.

* likewise for the left part of the switch

Figure 1

As shown in figure 1, the input of this device is the steering of bicycle handle bar sideways. After this, the device will receives the signal from the turning of the handle bar that will cause for the light bulbs to produce blinking light.

CHAPTER II

REVIEW OF RELATED LITERATURE AND STUDIES This chapter covers the review of related local and foreign literatures and studies that the proponents gathered from the internet, articles, studies and other unpublished theses conducted by particular research groups or individuals. This chapter expands the concepts and ideas of what the readers has in mind. Conceptual Literature Foreign Literatures According to the Vienna Convention, a cycle is a vehicle with at least two wheels that is propelled solely by the muscular energy of the person riding on that vehicle, in particular by means of pedals or hand-cranks. Furthermore, the Convention states that a cycle shall: a) have an efficient brake, b) be equipped with a bell capable of being heard at a sufficient distance and c) be equipped with a red reflecting device at the rear, and devices ensuring that the bicycle can show a white or yellow light at the front and a red light at the rear. In addition to the abovementioned "conditions for the admission of cycles to international traffic", some countries such as Germany and the Netherlands have supplementary regulations regarding mandatory equipment to ensure cyclists' visibility. Examples are a.) One white reflecting device visible from the front and b.)Orange pedal reflectors visible from the front and rear. Two wheel-mounted orange spoke reflectors on each wheel, arranged at an angle of 180˚ and visible from the side, or continuous white circular retro-reflector strips on the tires or on the spokes of the front and rear wheels. One additional red large-surface reflector on the rear. Mudguards to prevent mud from reducing the visibility of lights and reflectors. In some countries (the Netherlands, for example), standards for accessories such as children's bicycle seats have been drawn up. These standards include requirements and recommendations regarding seat attachment, dimensions, footrests, and protection against feet coming into contact with the spokes.

Germany has recently added new elements to its traffic code for cyclists. Since then, cyclists are allowed to ride contraflow in selected one-way streets, and in so-called bicycle streets cyclists may make use of the whole street whereas cars have to stay behind the cyclists. As in some Scandinavian countries, cycle tracks in Germany can be made compulsory only if they meet appropriate minimum quality standard, otherwise cyclists may choose not to use cycle tracks. In the study of John Duggan an avid cyclist and Seattle attorney who represents injured cyclists. Washington law states: "Every bicycle when in use during the hours of darkness...shall be equipped with a lamp on the front which shall emit a white light visible from a distance of at least five hundred feet to the front..." The law defines darkness as "a half hour after sunset to a half hour before sunrise." Because the statute states "every bicycle shall be equipped with a lamp" a helmet-mounted light alone would not comply with the strict interpretation of the statute. Furthermore, a red flashing tailight alone may not strictly comply with the statute either. Based on the wording, it appears that the primary purpose of requiring bicycle lights is so that motor vehicles can see you, not necessarily so that you can see. Although the law only requires that bicycle lights be used during the defined hours of darkness, "being seen" is just as important during the day as it is at night. I have investigated hundreds of bike/car incidents in the Seattle area. The common thread in nearly every one of these incidents is that the car driver was not aware of the cyclist until it was too late and often not until the moment of impact. The most common accident involves a left-turning car driver who simply does not see the oncoming cyclist. Awareness is the key. Cyclists simply do not have the mass or size of a car and are essentially invisible to motorists. Furthermore, there are not enough cyclists on the roads to make an impact. The everyday car driver is not accustomed to seeing cyclists on the road and, therefore, cyclists are not on the driver's radar screen. If a car driver only sees the occasional cyclist, he does not have a heightened awareness or an anticipatory thought process -- "Before I change lanes, I better look over my shoulder to see if there is a cyclist to my right." Or, "Although there are no cars approaching, I better scan to check for cyclists." Until there is a dramatic increase in the number of cyclists sharing the road with cars, this automatic, reflexive thought process

COLLEGE OF ENGINEERING on the part of motor vehicle drivers will not occur. Over the past few years, the market has been flooded with an abundance of small, lightweight and inexpensive LED flashers/strobes. The lights are simple to use and clip onto your handlebars or helmet in seconds. Using one of these inexpensive LED strobes during the day is the simplest and maybe the most effective thing you can do to increase your visibility during the daylight areas.

Local Literatures In the study of Richmond Sim (2015), with estimates of around P2.4 billion lost daily from our economy due to traffic congestion in Metro Manila, the current transportation bottleneck is something that should concern every Filipino. The amount could swell up to P6 billion by 2030 if unaddressed, according to Senator Paolo Aquino IV. The amount is no joke, and if we sum up the daily losses incurred by this situation, it could have been used to build world-class hospitals, research facilities, academic institutes, and defense equipment, among others. It would be easy for us to rather censure government offices such as the Metropolitan Manila Development Authority (MMDA) or the local government units (LGUs) that are responsible for ministering the traffic on their areas of responsibility, but playing the blame game would lead us to nowhere. I highly appreciate efforts from Malacañang by putting the Philippine National Police’ Highway Patrol Group (HPG) on the roads to man the flow of vehicles, but I believe this solution is only temporary and would eventually require long-term plans and solutions. The promotion of bicycles as a means of transportation should be supported by the government because not only is it economic but is also healthy for the cyclists and for the environment. Some may argue that riding a bicycle may actually be a health hazard and is dangerous in the metropolis because of high levels of pollution and the risk of getting along with vehicles. In this case, I strongly suggest for exclusive bicycle lanes.

COLLEGE OF ENGINEERING According to RIDENA (2015) a dedicated social hub for the biking community, many of the biking laws in the Philippines are similar to that in any other country. Some of the most common points include: 

All bicyclists must use helmets while riding bikes.



A permanent and regular seat should be attached to every bicycle.



While travelling at night, use rear reflectors and reflective material on the front and rear of each pedal or simply use front lamps.

Apart from that the bill has imposed restrictions on anyone carrying more persons on a bicycle than it was designed to carry and parking bikes in areas which are not marked for bicycles. Also, once bike lanes have been established, people travelling in automobiles or motorcycles will be prohibited from driving in bike ways. Other general etiquettes of riding a bike anywhere in the world include: 

Bicyclists must obey all traffic laws, including yielding to pedestrians.



Bikers must always keep at least one hand on the handlebars at all times.



Bicyclists should always stick to one lane and should not maneuver between vehicles.



Operators must report to local law enforcement, any accident involving either personal injury or property damage.



They must signal by hand if they have any intentions to stop or turn and give audible warnings whenever necessary to ensure safety.

Foreign Studies

Based on the studies of Conor CO Reynold, M Anne Harris, Kay Teschke, Peter A Cripton and Meghan Winters bicycling safety is usually quantified by measuring one or more of the following metrics: injuries; crashes; and conflicts. A conflict is normally defined as an interaction between a bicyclist and another road user such that at least one of the parties has to change speed or direction to avoid a collision. Types of conflict examined in bicycling safety studies include avoidance maneuvers at intersections bicycle-motor vehicle interactions during passing events on roads, lanes, or paths and "wrong side passing events" on multi-use paths. Conflict studies may offer valuable insights into how cyclists and other road users behave during their interactions on various types of transportation infrastructure. However, it is not possible to determine whether the safety of the cyclists was compromised during the conflict events. In addition, the conflict studies we identified were generally based on a small number of observed events, which were made over a limited time period (usually several hours), and often in a single geographical location. Ten of the 23 studies reviewed used injuries (or both injuries and crashes) as a metric of bicyclist safety, four examined injury severity, and nine examined crashes (i.e. collisions and/or falls). Most of the studies were published since 1994, except two US studies which were published in the mid-70s and one which was published in 1988. All the study designs were observational. Five of the intersection-related papers but only one of the road/lane/path-related papers were "before-after" studies that quantified the change in cyclist safety before and after some infrastructure-related intervention took place. The remaining papers were classified as "non-intervention" observational studies. Most of the studies based their analyses and conclusions on at least 150 observations of injury or crash events, and seven studies based their analyses on more than one thousand observations. However one study of roundabouts examined only 67 crashes, 58 of which resulted in injuries and two non-intersection studies examined 87 and 89 crashes on roads with and without marked bike lanes and on sidewalks versus roads respectively.

Based on the studies of Bert van Wee &Kees Maat the two studies of the safety effect of marked bicycle crossings at intersections looked at different design aspects (one on physically elevated crossings, one on colored crossings) and did not provide clear conclusions. Although the study on elevated crossings showed a small increase in the number of crashes after the crossing was installed, the bicycle traffic volume grew by 50% on the streets after the intervention, as compared to unchanged streets in the area, and this was not adjusted for in the analysis. The second study showed a reduction in injury or crash risk when there was one colored bicycle crossing at an intersection, but an increase in injury or crash risk when there were two or more colored crossings.

On-road marked bike lanes were found to have a positive safety effect in five studies, consistently reducing injury rate, collision frequency or crash rates by about 50% compared to unmodified roadways. Three of those studies found a similar effect for bike routes. One study found that there was an increase in crash rates in the year following installation of marked bike lanes on a major road, especially for a section counter to onroad traffic flow, but this effect was not sustained over the long term. There is less consistent evidence about off-road riding, possibly because this category encompassed a wide variety of facility types. There may have been confounding factors such as whether the surface was paved or unpaved, or for bicycles only or multiple user groups. Two studies examined off-road bike paths and found reduced risks, ranging from 0.11 to 0.67 times the risk of cycling on minor roads. Two studies that grouped paved and unpaved, bicycle only and multi-use urban trails in their off-road path category found elevated risks, 1.6 to 3.5 times higher than riding on-road. Studies that examined unpaved off-road trails as a separate category found risks of injury 2.5 to 7.2 times higher than onroad cycling and 8 to 12 times higher than bike routes, lanes, or paths.

Local Studies According to Gozun, Brian C. (1999) the benefits of bicycle transportation range from the creation of mobility for commuters to the overall improvement of the environment and the commuters’ health. Of course, cycling contributes to the sustainability of the urban development. However, given cycling’s numerous advantages, only 2% of trips in the National Capital Region are made by bicycles and most of these trips are in less congested areas of the big cities (Promoting 2005). In order to find out the main reasons why bicycle has never really been a significant transportation mode choice, a study by Gozun (1999) focused on the role of personal attitudes and community values that that could affect the potential use of cycling in the non-cycling community of the University of the Philippines (UP) in Diliman, Quezon City, Philippines. The study of attitudes and perception is important in the overall transportation planning process where the first step usually takes into account the perceptions of the commuters in the possibility of adding a new transportation mode. Moreover, the study focuses on UP Diliman’s student population in the belief that college students have a higher rate of cycling compared to the general population (Baltes 1996). College students are more likely to cycle for a number of reasons: low incomes, limited campus parking, predominance of short trips to classes and nearby activities, and compatibility with cycling’s casualness and sporty image. However, in UP, the main barriers stated are the unavailability of bicycles, inability to use bicycles, security issues and a perceived hostile environment. A major issue among the respondents is that there is no “image” of bicycle as a useful transportation mode. In fact, even respondents who find cycling as a good recreational sport do not think of cycling as a viable transportation mode. There is a common misconception that lingers where cycling is not considered a commute mode. Another interesting fact is that there is also a seeming gap between potential users and supporters of a cycling policy. The study revealed that not all supporters of a cycling policy are potential users of bicycle facilities. Although XIII Back to menu Retour au sommaire 4 supporting cycling is beneficial, there is still a need to transform these supporters into actual users in order to instill a tradition of cycling for utilitarian purposes.

According to the study of Guillen, Marie Danielle (2000) the University of the Philippines Diliman is located in a sprawling 493-hectare lot with academic zones and residential zones and in it is a good place to cycle given its flat terrain and abundance of trees. The study also revealed that respondents are willing to use bicycle facilities if ever built in the campus. Given this premise, a student organization called UP Mountaineers has initiated a project called “Padyak” is the Philippine word for “to pedal”). This project was spearheaded by the alumni of this organization where they rent out bicycles to promote cycling, environmental protection and a healthy lifestyle. Although the project is in its infancy stage (it only has 16 bicycles at present), the response of the students has been overwhelming given the long waiting list. The organization is now actively encouraging the university administrators to build and maintain bicycle racks in order to guard from the possibility of theft which is a high concern of students. Of all the municipalities and cities in the Philippines, the most commendable is Marikina which is located one hour east of Manila. In fact, Marikina City has been adjudged as the “Healthy City” for promoting bicycle use and building a 30-kilometer exclusive bicycle lane which is a first in the country. The program has been a success for they are now building the next 30 kilometer stretch of the bicycle lane. One of the factors that have contributed to the success of the program is the city council’s forward-looking land use and transportation plans which include an integrated bikeways system. The presence of a bikeway office that conducts bicycle safety education campaigns has been very beneficial in promoting cycling use. Moreover the presence of bicycle patrol volunteers that roam around the city and report untoward incidents to the police. There are also interest-free bicycle loan programs for low-income city employees as well as annual summer cycling events and competitions that promote the use of cycling

RESEARCH AND METHODOLOGY

This chapter presents the particular of the research, the design, research method, procedures, components utilized and evaluation of the design project. It will deals with the methodologies that will be used as well as source of data materials utilized to obtain the objective of the study. It includes project design, research design, project development, operation, testing and procedures.

Project/Research Design As stated the purpose of this project is to create a “one click” turn light that can helps the bicycle enthusiast to lessen their bicycle accident. Normally, the electromechanical types of turn signal indicators are not reliable due to low consistency and vulnerability to changing weather conditions. The present design easily withstands the in any weather condition and more importantly consists of an attached buzzer indication facility. The inclusion of an audible signal makes it sure that once the required deviating turn is completed by the vehicle; the cyclists remembers to switch off the unit and save precious battery power. Conventionally a turn signal indicator will require three output terminals for its correct operation. Uniquely the proposed circuit works with just a couple of terminals, and incorporates a built-in buzzer.

Project development These are the actions made by the proponents in creating the design project. 1) Planning

In this stage, the proponents planned the design of the bicycle turning indicator. The proponents decided to use the usual size of the bicycle. The proponents studied the JFET and MOSFET application. The proponents used the SPDT switch as switch as an oscillator The proponents together with the advice of their professor, the mechanism of the bicycle turning indicator was designed to eliminate hand sign and to lessen the bicycle accident. 2) Prototyping

In this stage, the proponents designed the circuit that will be used as an indicator. The design was made. The overall appearance and mechanism of this design is also part of this stage.

3) Testing For testing, the proponents tried to ride the bicycle and observe its effectiveness and other circumstances which can be improved and innovate. 4) Documentation The documents that supported this design project are used to aid the future proponents in understanding the deeper technical side, aspects, and

16

Pamantasan ng Cabuyao Katapatan Subd., Banay-banay Cabuyao, Laguna

COLLEGE OF ENGINEERING theories involved. This involves the components and circuits used, tables, and diagram that are needed to further understand the process.

Making this project happen has been a great learning experience, especially on time management and project planning. The proponents were able to get a prototype and running on a breadboard but the most time consuming part of this project was the construction of the project. In order to make this project more permanent, the proponents decided to transfer the prototype to small PCB together with the battery and the switch.

Operation The operation that happen in the circuit was stated as it how it operates. 1. As the SW1 in “on” state and SW2 in “on” state in its side, the current from the battery starts to flow in the conducting circuit. 2. The one transistor is in saturation region, other transistor will be in the cutoff region, so the LED in cutoff region will glow and the LED in saturation region will not glow. On the next cycle, the cutoff transistor will goes to saturation region and the other will be vice versa and the output get inverse. 3. The capacitor ionize when the voltage got high enough, lighting up and conducting until it had discharged enough the capacitor. On that stage it could no longer stay ionized and then stop conducting for another charging cycle. 4. The output from the capacitor will be receive by the potentiometer that will resist the voltage which flows through it. As the resistance of the potentiometer increases, the current will decreases which results in a slow rate of blinking of light and beeping sound. Otherwise, the current will increases which results in a fast rate of blinking of light and beeping sound. 5. As the SW2 is “on” state where the LED lights and buzzer connected, the resistors controlled the brightness which limits the LED current and ensures that the amount of current that flows does not exceed what the circuit can safely handle .As the current passes through LED lights and buzzer, it emits visible blinking light and produce a beeping sound, respectively.

Capacitor

Determined the flashing duration together with potentiometer, which would ionize when the voltage got high enough, lighting up and conducting until it had discharged enough the capacitor.

Resistor (Potentiometer)

Determined the flashing duration together with the capacitor where time width of output pulse may vary, current-limiting resistor that control blinking rate of the LED. Potentiometer needs to be dynamically changed to control the current across the LED to increase or decrease the flashing rate. 

Switch

Used to function the project. A constituent electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another. 

SPDT Switch (Single-Pole Double Throw)

An indicator for the signal light (left or right), serve to connect in two various paths that may need to function. Serve as on and off switch that can connect ready mode and standby signal light. 

Transistor

The main heart of the project act as a stable switch, which work in its saturation and cut off region, acts like a two switch which gives the complement outputs. The basics is that when one transistor is in saturation region, the other transistor will be in the cutoff region, so the LED in cutoff region will glow and the LED in saturation region will not glow. On the next cycle, the cutoff transistor will goes to saturation region and the other will be vice versa and the output get inverse.

COLLEGE OF ENGINEERING Recommendation This project has potential for improvement. 1) This device can be upgraded to a case which is more stronger by creating more a customized hard case made by professional welders. 2) Do not do this circuit like we used to do. This device made me feel bangag more than ever. It will only make you feel upset and sleepy because sleeping is not available.
