Driver Error

The factor of driver error in driving (human error) is one of the causes of the high number of traffic accidents in the present. To anticipate this, the discipline and concentration of the driver when driving is needed. However, when drivers have discipline and sufficient concentration of accidents can still occur. Therefore, the quality of the vehicle security system also greatly affects safety when driving. With the development of science and technology today it is very possible for humans to make security systems in vehicles. Accidents are often caused by the driver being unable to react quickly when there is a sudden blocking of objects. Especially when the driver is driving at high speed. This can be overcome by automating the braking system, so that the vehicle's speed will slow down even though the driver does not step on the brake lever. So that the possibility of an accident can be avoided. And automation is expected to be implemented in vehicles widely. In this study, designed a brake automation system using fuzzy logic by making a prototype. This prototype serves as a visual aid to evaluate the workings of the membership functions that will be used. From this evaluation it is known the value of each membership function. These values ​​are used as the main parameters in determining the Rules that will affect the output value of the brake force. With these Rules, automation of the brake system can work optimally. And it is known that the distance of the prototype car can run between other obstacle with a width of 50cm and the braking of the prototype car stops completely when the prototype is ± 5-10 cm with the obstacle in front of it. Keywords: Automation of Brake Systems, Fuzzy Logic, Distance, Speed.

Ari Hidayanto, Heru Winarno  in this paper explain that The high number of traffic accidents is currently a factor in the driver's error in driving (human error). One of the accidents that often occur include car accidents. Of the several incidents that have occurred, the average accident occurred because of the driver's lack of concentration in driving his car. This resulted in the driver not being able to control the speed of the vehicle immediately when there was a sudden object in front, moreover this happened when the vehicle drove at high speed. To avoid this, when driving, it really needs a vehicle security system that also greatly affects the driver's safety. With the development of existing science and technology allows humans to make security systems in motorized vehicles. Accidents due to driver negligence can be overcome by making the braking system automatic then the vehicle speed will slow down and carry out mechanical braking (disc brake) automatically based on the minimum distance of the car with the barrier even though the driver does not pull the brake lever. Realizing this, an autobrake system (automatic braking) was designed based on the distance of the car with the barrier using the HC-SR04 ultrasonic distance sensor. When between a sensor and a barrier at a distance of <= 70 cm, the central lock actuator will go forward and press the disc brake lever. System notifications will be displayed via 20X4 LCD, LED and Buzzer. The system work will be controlled by Arduino Mega 2560. Keywords: Autobrake, Disc Brake, Ultrasonic sensor HC-SR04, Central Lock,  LCD 20x4, Arduino Mega 2560ReferencesAgus Setya Abadi, Delta. 2008.

Recently, accidents involving ground transportations are getting worse and more serious. Indonesian State Police (Korlantas POLRI) recorded the number of accidents in 2018 as many as 109,215 accidents. The number has incresed 4.69 percent compared to 2017 as many as 104,327 events. Road traffic accidents are caused by human error, the driver in this case. The driver's mistake is influenced by several factors, one of them is they cannot expect the road condition when they drive a vehicle at high speed. To solve this problem, drivers need information that can show road conditions. So, we present a new approach for detecting damaged roads by applying augmented reality technology. This research produces a road condition information system to help drivers get information about road conditions via smartphone. This system uses augmented reality technology with a markerless GPS Based Tracking method. The development of this system requires several stages such as collecting the data, data conversion, data classification, and views road condition. The researchers gathered the road condition data from the Public Work Department Semarang. This department itself undertakes a task to control the road condition in Semarang The trial of this system includes all drivers in Semarang city. Based on the results of the questionnaire responded to by 93 respondents, this test obtained an average value of 68%. So this system gets a pretty good response from the driver. Through this system, all drivers can avoid the damaged road condition which can cause traffic-congested and accident.

This paper proposes a cheap and effective method to interface the concept of FUZZY LOGIC and (Antilock Braking System) ABS system used in cars and bikes for preventing the condition of wheel locking and wheel slipping and if wheel slipping occurs then how much of intensity of brake should be applied to keep the vehicle in control of the user. This decision is taken by Fuzzy System which makes decision based on user inputs namely Obstacle, Brake force and Slip ratio. The Fuzzy system gives an Pulse Width Modulation output based on three intensity levels of brake will be applied such as High Brake , Medium Brake and No Brake. Hardware Implementation consists of an MCU which is interfaced with an LCD and DC Series motor which displays intensity of brake applied and motor represents the motion of the actual wheel of a vehicle respectively.

Jakarta merupakan salah satu kota megapolitan yang mempunyai jumlah angka kepadatan penduduk yang sangat tinggi. Tingginya angka kepadatan penduduk di Jakarta membuat laju pertumbuhan pengguna kendaraan bermotor menjadi sangat besar yang menimbulkan kemacetan. Kemacetan yang sering melanda Jakarta membuat masyarakat berganti untuk menggunakan moda transportasi lain yaitu KRL (Kereta Rel Listrik) yang diyakini masyarakat Jakarta sebagai moda transportasi yang aman, murah, dan cepat. Namun, seiring berjalannya waktu minimnya pengembangan teknologi pada transportasi KRL menyebabkan terjadinya beberapa kasus kecelakaan tabrakan pada kereta rel listrik. Banyak faktor yang mempengaruhi tingkat kecelakaan tabrakan seperti sistem komunikasi yang kurang baik, human error, dan pengguna kendaraan bermotor yang tidak tertib saat melintas palang pintu perlintasan kereta. Hal tersebut membuat tingkat keselamatan para pengguna moda transportasi KRL menjadi menurun. Pada penelitian ini, teknologi AEB yang sering digunakan pada mobil akan diaplikasikan penerapannya pada sistem pengaturan rem otomatis yang terintegrasi pada kereta api. Didukung melalui inovasi teknologi ini yang mengusung metode sistem otomatisasi (Automation System) berupa sistem pengaturan rem otomatis yang saling terintegrasi menggunakan sistem berbasis Embedded System pada sensor ultrasonik yang berfungsi untuk mendeteksi jarak obyek yang melintas di depan rangkaian kereta rel listrik. Data yang dikirimkan oleh sensor akan diproses oleh kontroler untuk mengkalkulasi jarak obyek dari sensor yang berguna untuk pengaturan rem otomatis. Sehingga diharapkan AEB dapat menjadi sebuah solusi untuk membantu meminimalisir tingkat kecelakaan tabrakan pada KRL (Kereta Rel Listrik).

In all kinds of traffic accidents, the unconscious departure of the vehicle from the lane is one of the most important reasons leading to the occurrence of these accidents. In view of the specific problem of lane departure, a lane departure decision-making method is established without calibration relying on the Kalman filtering fuzzy logic algorithm, according to the characteristics of expressway lanes, based on the machine vision and hearing fusion analysis of lane departure, integrating the extraction of the linear lane line model and the region of interest (ROI) in this paper to judge the degree of vehicle departure from the lane by integrating the slope values of the 2 lane lines in the road image. The results show that the system has good lane recognition capabilities and accurate departure decision-making capabilities, and meet the lane departure warning requirements in the expressway environment.
