In Tanzania, motorcycles taxi has emerged as the key mode of transport for both rural and urban areas. The numbers of motorcycles and motorized tricycles in Tanzania has increased rapidly in recent years, changing the face of accessibility and mobility. Motorcycles provide employment and business opportunities for tens and thousands of people. However, the increase of motorcycles causes the increases in fatal accidents which takes the lives of much younger one and leave many others crippled. The governments of Tanzania and other stakeholders have been intervening for the purpose of reducing fatal accidents though instituted efforts have not been able to solve the problem. Among others consuming excessive alcohols and not wearing helmets have been the major causes of fatal accidents and injuries. This research aim at solving the problem by preventing riders accessing the motorcycle when they are either drunk or have not worn the helmet, the research develops a prototype which automatically prevents the motorcycle from starting when any of the two requirements are not met. A sample of eighty(80) respondents was visited using a structured questionnaire using simple random sampling technique, to present findings data were analyzed used an IBM SPSS software.

In present time many cases of bike accident can be seen around us. peoples get injured or might be dead and one of the reason is not wearing helmet. Many peoples could save their life in accident cases if they weared helmet at the time of accident. Continuously road rules are violated. So as to overcome these problems, an Smart helmet is proposed having a control system built inside a helmet. Smart Helmet for Motorcyclist is a project undertaken to increase the rate of road safety among motorcyclists. The idea is obtained after knowing that the increasing number of fatal road accidents over the years is cause for concern among motorcyclists. It consist a RF transmitter and a RF receiver system. the bike will not get start without wearing helmet by the user, as user wear helmet a rf signal radiate from transmitter and once these rf signal get sensed by the receiver placed in the ignition switch of the bike, bike will get start. Security system applied in this project meet the characteristics of a perfect rider and the application should be highlighted. The project is expected to improve safety and reduce accidents, especially fatal to the motorcyclist.

The objective of our smart helmet is to provide the means for detecting and reporting accidents. The working of this smart helmet is very simple; vibration sensors are placed in different places of the helmet where the probability of hitting is more, which are connected to the microcontroller board. When the rider met with an accident and the helmet hits the ground, these sensors sense and gives to the microcontroller board, then controller extracts GPS location using the GPS module that is interfaced to it. When the data exceeds the minimum stress limit then the GSM module automatically sends a message to the registered emergency contacts and the link through which the location and the speed of the victim will be displayed in the mobile application and in a web application.

An accident is an unexpected, unusual, unintended external action which occurs in particular time and place. Carelessness of the driver is the major factor for accident. The government has made rules that rider should compulsory wear the helmet and not consume alcohol and drive. Still the riders do not obey the rules. These accidents are caused due to negligence of the rider. Not wearing the helmet causes the rider with head injuries which may lead to death of the rider. In order to overcome this an intelligent system, smart helmet is proposed, it detects the helmet and also the alcohol present in rider’s breath. This system has a pair of transmitter and receiver, the transmitter is placed in the helmet and the receiver is placed at the bike ignition. There are different sensors to ensure the helmet is on the head. These vibration sensors are placed in helmet where the probability of hitting is more. An alcohol sensor is placed near mouth of the rider. The alcohol sensor detects the presence of alcohol in rider’s breath. The data of the detection of helmet and alcohol is coded with RF encoder and then transmitted through radio frequency transmitter. The receiver at the bike receives the data and the data is decoded using RF decoder. The result of presence of helmet and the alcohol detection is analyzed on the smart phone. The proposed system will be so designed that if one of the two conditions are violated then also the bike won’t start. The bike will start only if the both conditions are followed. This smart helmet will help the rider to compulsory wear helmet and restrict drink and drive condition. MCU controls the function of relay and the ignition, it control the engine through a relay and a relay interfacing circuit.

The impact when a motorcyclist involves in a high-speed accident without wearing a helmet is very dangerous and can cause fatality. Wearing a helmet can reduce shock from the impact and may save a life. There are many countries enforcing a regulation that requires the motorcycle's rider to wear a helmet when riding on their motorcycle, Malaysia is an example. A smart helmet is a special idea which makes motorcycle driving safer than before. This is implemented using GSM and GPS technology. The working of this smart helmet is very simple, vibration sensors are placed in different places of helmet where the probability of hitting is more which are connected to microcontroller board. So when the rider crashes and the helmet hit the ground, these sensors sense and gives to the microcontroller board, then controller extract GPS data using the GPS module that is interfaced to it. When the data exceeds minimum stress limit then GSM module automatically sends message to ambulance or family members. It also has an alcohol detector sensor which detects whether the person is drunk and switches off the engine if the sensor output is high.

This paper focuses on implementing Microcontroller based "Smart locking system". Programmable Microcontrollers are used in order to perform required operation. The research survey includes the current technology/scenario of locking system. This helmet locking system is implemented to assure that the rider wears a helmet before rides the bike. Just in case the user takes out the helmet from the lock but doesn't wear it, the helmet is installed with two-step verification by implementing a limit switch in the helmet and communicate with the system wirelessly. It also assures that the bike speed doesn't cross a threshold limit and if at all the speed exceeds the pre-set limit there is an intimation and the rider is asked to slow down. Ultra-sonic sensor, limit switch sensor, speed sensor, rotary sensor and LCD are used as components. RF transmitter and RF Receiver are used for exchange of information. Carbon di oxide sensor is implemented to the exhaust which gives the percentage of the unburnt fuel. As a result, the bike ride becomes safer than before.

An accident is a specific, unexpected, unusual and unintended external action which occurs in a particular time and place, with no apparent and deliberate cause but with marked effects. Carelessness of the driver is the major factor of such accidents [1]. The traffic authorities give a lot of instructions to the vehicle operators. But many of them do not obey the rules. Nowadays most of the countries are forcing the motor riders to wear the helmet and not to use the vehicles when the person is in drunken condition. But still the rules are being violated by the users. In order to overcome this we introduces an intelligent system, Smart Helmet, which automatically checks whether the person is wearing the helmet and has non-alcoholic breath while driving. Here we have a transmitter at the helmet and the receiver at the bike. There is a switch used to sure the wearing of helmet on the head. The ON condition of the switch ensures the placing of the helmet in proper manner. An alcohol sensor is placed near to the mouth of the driver in the helmet to detect the presence of alcohol. The data to be transferred is coded with RF encoder and transmitted through radio frequency transmitter. The receiver at the bike receives the data and decodes it through RF decoder. The engine should not ON if any of the two conditions is violated. MCU controls the function of relay and thus the ignition, it control the engine through a relay and a relay interfacing circuit.

The system is to build a safety system, which is integrated with the smart system and intelligent bike to reduce the probability of two-wheeler accidents and drunk, and drive cases. Alcohol sensors detect the alcoholic content in the rider's breath. When the rider is on the bike if there is alcohol content found in rider's breath, the bike remains off. The bike will not start until the rider blows the air and if there is no alcoholic content present stating that rider did not consume alcohol. When the rider crashes, bike hits the ground and sensors detect the motion, tilt of bike, and report the occurrence of an accident and sends information of the location of accident to the family members of the rider and the emergency contact numbers.

An accident is a specific, unexpected, unusual and unintended external action which occurs in a particular time and place, with no apparent and deliberate cause but with marked effects. Carelessness of the driver is the major factor of such accidents. The traffic authorities give a lot of instructions to the vehicle operators. But many of them do not obey the rules. Nowadays most of the countries are forcing the motor riders to wear the helmet and not to use the vehicles when the person is in drunken condition. But still the rules are being violated by the users. India has the largest number of road accidents in the world out of which 22.4% of victims are occupants of two wheelers, 30% of road accidents victims die at crash site, 14% in ambulance and rest in hospital. Our proposal is to reduce the number of deaths which occur at crash site and on the way to the hospital due to delay in Emergency Trauma Care Services.

The idea of developing this paper comes from the social responsibility to prevent the people from the road accidents. This aims the safety and security for the bike rider. The purpose of the paper to encourage the people to wearing helmet. This system ensures that the bike will not start unless the driver does not wear the helmet and has not consumed alcohol. This system alerts the bike rider if any obstacle comes to rear part of bike. If accident occurs then the GSM module sends the message signal to the nearest police station, relatives and other people whose name is registered in module.
