Automatic control in vehicles" is a unique speed governor for vehicles at specified zones. This system ensures that the car will travel at or below the speed limit specified at designated areas. Transmitters are installed at the entry point of specified zones, primarily on the speed sign boards to reduce project implementation cost. The Transmitter consists of an encoder and a RF transmitter module with 433 MHz carrier frequency and ASK modulation which transmits the speed limit of that area. The Receivers are installed in all vehicles. A Receiver consists of a decoder, RF receiver module and a micro controller "89S51" along with sensors viz. Alcohol sensor, collision sensor and theft sensor. Upon the detection of drunken driving or collision the car decelerates to a stop. The Receiver has a GSM module which sends the message to the respected mobile user upon the event of collision, theft and drunk driving. In the microcontroller, the speed of the vehicle is compared to the speed limit of that area and the speed is then accordingly controlled.

Digital Technologies and Applications

Every year, millions of people around the world die from road accidents, excessive or unsuitable speed is one of the main factors responsible for accidents, and it is implicated in a third of deaths. The main objective of this paper is to follow the driver from the speed of the vehicle as well as to know his behavior and his physical state on the roads to reduce the risk of accidents. In this paper, we monitor the instantaneous speed of the vehicle using a control system that can be mounted in any vehicle equipped with the OBD-2 protocol (on-board diagnostics). A monitoring chain based on a PIC microcontroller will be mounted in the vehicle as well as other peripherals such as an SD memory card module, a GPS geographic positioning sensor, a shock sensor and a global system for mobile communications GSM module. Unauthorized speed and the location data of the vehicle will be recorded in the SD memory card with accurate date and clock. In the event of an accident, an emergency message containing the latest speed and position data will be sent through the GSM module to the nearby medical center and local police as well as to the operator or owner (in case of car rental).

An intelligent traffic guidance system is designed to provide real time information about the vehicle traffic situation online. In this concept, every vehicle on road is equipped with a RF-ID tag and a GSM module. RF-ID Receivers would be employed at particular zones and intersections, which will sense traffic conditions based on the RF-ID tags of vehicles. The information would be provided to a server or central governance system which would be analyzed and further forwarded to the user about traffic condition through GSM network. This information will be displayed on LCD screen in form of Maps and real time condition. This data would also be useful in routing the traffic through traffic signals based on traffic density and avoid traffic jams and chaos. Moreover special RF-ID’s would be provided to the emergency vehicles (i.e. Police, Ambulance etc). During emergency these vehicles will be detected and the traffic ahead will be notified to make way for the vehicle. Further every ve...

Abstract: Vehicle speed is a daemon in road safety. Accidents on motorways have become a critical concern for the governments of various developed and developing countries. Speed detection and alerting the driver best possible by Intelligent Transport System (ITS). ITS also has capability to take over the speed control of vehicles by using satellite. Intelligent Speed Adaptation (ISA) uses satellite based GPS technology to indicate to a vehicle about its own location and the speed limits. ‘Active’ ISA then exercises automatic control to the vehicle’s engine and braking system so that the driver cannot exceed the speed limit. The trials of ISA are under process in the UK, the Netherlands and Sweden. Evaluation of the UK trial indicates that mandatory active ISA could achieve significant annual fuel savings. There are mainly three speeds related to design and operation of every road, these are, Design Speed (Highest speed used for design of a road), Posted Speed (Allowed maximum speed limit for drivers) and Operating Speed (Normal speed of vehicles on a motorway, which is less than Design speed and the Posted speed). A serious study is presented in this paper for general public as well as researchers across the world. It is therefore an invaluable document for interested users.

Driving or Riding a vehicle in India is by large becoming a dangerous experience. Of Worldwide annual average of 70,000 road accidents, 10 percent occur in India. The latest annual statistics indicate that over 80,000 people are killed on Indian roads due to not following the traffic regulations by the driver. The project addresses this serious issue and proposes a low-cost dynamic electronic speed monitoring unit. The proposed project comprises of hardware design using a low-cost 8-bit AT89S52 microcontroller and the complete hardware design will be proposed which will continuously monitor the speed of the vehicle and senses the other vehicles which are going front and back, computing the distances of the vehicles during the journeys. The embedded software design is proposed using keil µ vision 4IDE that will continuously update the accidental danger zone threshold limit in front and back. The system uses an IR sensor based hardware design connected to the 8-bit CPU for real-time speed adjuster and threshold mapping. A relay indicator is connected to alert the driver if any vehicle is running on either side of the vehicle, within the threshold danger limit. The system design uses various debugging tools such as Null modem checking, Keil µ vision 4C51 debugger and serial debugging utilities are used for testing the design during the implementation phase.

Here, the focus is to control the traffic on bridge as well as on road by using the traffic control optimizer, this setup is provided for the foot path and also the divider of the road which is used to control the traffic by providing extra space on the road during over crowd conditions. Traffic is a major problem in modern era. Morning to evening, till late night, each one is facing a problem every day. According to the survey, According to "TRAFFIC CORPORATION OF INDIA and IIM KOLKATA" in the year 2012 there is loss of 60,000 crore rupees of India per year due to traffic jam. The study revealed that on 17 big routes of country there is a national fuel mileage of 3.96 kilometres per litre. According to the survey of "Centre for Transforming India" in 2010, there is loss of 2.5 litre of fuel per day in car and 0.7 litre of fuel per day in bike. Due to traffic jam, there is a loss of 90 minutes per day of an average person, if we would calculate it in years, about 23 days an average person wastes in traffic. According to study of IBM the 40% of productivity of the country decreases due to wasted time in traffic jams. Thus the main purpose of making this optimizer is to control the jam by shift down of the footpath (using IR sensor), if there is no crowd on other side of lane then it shifts the divider towards the other side of road at some definite length. In this whole phenomena, IR sensor which sends signal to the microcontroller and operates motorised scissor jack which provides path on the road.

For today's life the control of the speed of vehicle has become mandatory and very essential for life purpose. Thus, the prior aim is to control the speed of the vehicles in different areas of cities as well as in the speed restricted zones such as hospitals, schools, colleges, parks, more people populated zones, speed breakers areas, etc. In today's day to day fast life people in the world tends to lose their self-control on their vehicle. They drive in such a high speed which can be dangerous for themselves as well as for the surrounding. Even the monitoring of police is not sufficient in such cases. Some situations can also be fatal. In automobiles from the inputs received through the accelerator pedal position sensor to the Electronic Control Unit we control the throttle position so that the variation according to the load and speed can be arranged. However in this model the input of pedal position from sensor is received to a microcontroller unit which acts as an primary interface with the input and then transmits to the ECU. [1] There are RFID Tag zones which are programmed in such a manner that whenever the RFID reader comes in proximity to its zone this Tags get actuated .In this actuation vehicle's speed is controlled through the code signal automatically due to the microcontroller unit installed in the vehicle. Such tags are placed mostly in the accident prone areas where speed reduction is mandatory.

In this paper, this paper seeks an answer to the question: can a vehicle automatically report to the emergency units its position and speed when an accident is occurred? It presents an approach that relates to an accident detection and prevention system. It is particularly related to a system that sends a message to designated parties (such as vehicle owner and emergency helpers) when a certain speed has been detected and when an accident has been detected with a resulting speed below a certain threshold. The proposed system includes a microcontroller, modem, nock sensor, and speed selection box is used to send messages when a certain speed has been exceeded and when an accident has occurred and the resulting speed of the vehicle is less than a predetermined threshold. The message sent can be a text message sent over a GSM modem.

In the present day scenario traffic rules are frequently violated by the drivers and over speeding occur due to bad driving behavior's. So driver assistance system is provided to prevent over speed, violations of road rules and also to display alert messages on LCD. The proposed violation management system has an alerting, reporting and recording system for over speed violation management. The RF transmitter sends the speed limit of the particular lane entered by the vehicle in LCD. The receiver unit placed in the vehicle receives the messages and sends to the microcontroller and stores the speed limit of zone. When speed of the vehicle near the speed limit it displays the warning and if it exceeds the speed limit, the microcontroller records the violated speed and time. The LCD displays the lane speed limit and RF Tx module sends message to the nearest traffic personnel immediately after a violation occurs. An authenticated module is also provided, which can be operated only by...
