AbstractThe number of on-road vehicles have increasing day by day, thereby increasing the air pollution, wasting the fuels in traffic and parking areas particularly in metropolitan cities. In these areas most of the traffic jams where happening. At the time all the vehicles have run only in 1st gear or 2 nd gear, by this way there is huge amount of fuels get wasted. To overcome this situation the switch over method is used in it, which means at the time of traffic and parking area the vehicles have run through the DC motors by the help of ultrasonic sensors, line following sensors. At that time hand brake and car steering get unlocked. It can be controlled through the wireless sensor network. In the parking area whether the vehicle identifies any space, it automatically gets parked at the available space with help of line following technique and after that hand brake and car steering get locked and also motor get into off condition after the vehicle get parked. Again the user can pick up their car through RFID. In that situation hand brake and car steering get unlocked and motor get starts automatically. And then in the traffic area by using the obstacle detector the vehicle moves autonomously and separate space is allocated for ambulance and two wheelers for emergency purpose. In this driving the power supply is given to the motors through the solar panel and car dynamo.

I. INTRODUCTION

In this world the daily requirements are very difficult to produce as well as the people supposed to destroy the environment for their needs. By using vehicles like four wheelers are wasting the fuels in the traffic and parking area.To control this situation there is the idea to make the vehicle to run autonomously by the help of DC motors without starting the engine. Because electric car does not give more efficient mileage for long travelling. So to implement this concept in fuel cars to avoid more fuel wastages. In the Fig 1 and Fig 2 says many countries launched the rules in traffic and parking areas. By using this method to the idea can implement in it.

1. EXISTING METHOD

   1. Traffic System

      In traffic & parking area mostly all the vehicles moving in 1st or 2nd gear, in that way there is more number of fuels get wasted. In the below screenshots indicates the wastage of fuels in one metropolitan city. In below Fig 3 represents the proof of google search.

      Fig 3 : Google search of fuel wastage

      In the below concept Fig 4 represents the traffic areas are monitored and stored in the database by the cloud computing process. In that way the traffic instruction are communicate to the vehicle drivers. Through that the drivers are change their direction in the less traffic way. In this way the travellers can save their time.

   identifies any space, it automatically gets parked at the available space with help of line following technique. The instruction to the vehicle is giving through RFID. And also in traffic area this technique is used to run the car automatically. By using the obstacle detector sensor the car can drive safely and then the vehicle could not overtake another vehicles to avoid the accidents in traffic jams.

2. PROPOSED METHOD

   1. Hand Unit

      Fig 6 : Proposed method Block Diagram (Hand Unit)

      In this unit Fig 6 represents there is two types of the control should be handled in the appropriate areas. In the parking area all the sensors have worked for accurate parking. And in the traffic areas the obstacle detector sensor have work to avoid the overtaking another vehicles and also to avoid accident.

   2. Vehicle Unit

   To Overcome the existing method Fig 7 represents there is the idea to introduce the new techniques. To find the space availability, ultrasonic sensors are used. Whether the vehicle

3. SYSTEM WORKING

   The proposed idea is to make the vehicles parking easy and safely. This project consist of two units, vehicle unit and hand unit. The vehicle unit is controlled through the RFID. In that time the vehicle is switch over the control of engine to the DC motors. And then to find the space availability,ultrasonic sensors are used. Whether. the vehicle identifies any space, it automatically gets parked at the available space with help of line following technique. This project will reduce the constraints in parking and saving the precious time of vehicle owners and also the consume more fuel. It should also helpful in Traffic area.

4. HARDWARE USED

   1. Microcontroller

      PICs are popular with both industrial developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability Various microcontrollers offer different kinds of memories. EEPROM, EPROM, FLASH etc. are some of the memories of which FLASH is the most recently developed. Technology that is used in PIC 16877 is flash technology, so

      that data is retained even when the power is switched off. Easy programming and erasing are other features of PIC 16F877. PIC16F877A microcontroller is used in the project.

      PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1640.Originally developed by General Instrument's Micro electronics Division. The name PIC initially referred to "Programmable Interface Controller".Microcontroller is a general purpose device, which integrates a number of the components of a microprocessor system PICs are popular with both industrial developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability. Microchip announced on February 2008 the shipment of its six billionth PIC processor.

      • It has inbuilt CPU, memory and peripherals to make it as a mini computer. A microcontroller combines on to the same microchip:

      • CPU core

      • Memory (both ROM and RAM)

   2. IR Sensor

      IR Transmitter

      An IR LED also known as IR transmitter, is a special purpose LED that transmits infrared ray in the range of 760nm wavelength.

      Fig 9 : IR LED

      An IR LED shown in Fig 9 also known as IR transmitter, is a special purpose LED that transmits infrared ray in the range of 760nm wavelength. Such LEDs are usually made of gallium arsenide. The appearance is same as a common LED. Since the human eye cannot see the infrared radiations, it is not possible for a person to identify whether the IR LED is working or not, unlike a common LED.

      IR Receiver :

      An IR led is operated in forward bias just like any ordinary led. When it is in reversed biased condition if there is no light falling on the diode it will decreased and TX. The basic sensor circuit will be as follows

      Fig 10 : Circuit Diagram of IR receiver

      When the sensor is placed in front of a white surface the light emitted from led gets reflected on to diode so the

      photodiode act as a short circuit. So the voltage at the output will be almost equal to 0v in case of black body or space then no light falls on the diode so it will act like an open circuit. So voltage at output will be almost equal to 5v.

   3. Ultrasonic Sensor

      Fig 11 : Ultrasonic Sensor

      1. Working Principle

         In fig 8 represents the Ultrasonic ranging module offers a 2cm – 400cm non-contact measurement function, the ranging accuracy could reach up to 3mm. The building

         modules includes ultrasonic transmitters, receiver and control

         circuit.

         The basic principle:

         1. Making use of IO trigger for at least 10us high level signal

         2. The Unit inevitably sends eight 40 kHz and detects whether there is any pulse signal back.

         3. If any of a signal is received back in a high level, time of high output IO duration is the time from sending ultrasonic signal and receiving it back.

            Test distance = (high level time× velocity of sound

            (340M/S) / 2

            RFID reader for its operating power and undoubtedly have a lower range limited up to few meters.

            Fig 12 :Hardware of RFID E. Encoder HT12E:

            The HT12E encoder is a CMOS IC built especially for remote control system applications. It is capable of encoding 8 bits of address (A0-A7) and 4 bits of data (AD8-AD11) information. Each address/data input can be set to one of the two logic states, 0 or 1. Grounding the pins is taken as a 0 while a high can be given by giving +5V or leaving the pins open (no connection). Upon reception of transmit enable (TE- active low), the programmed address/data are transmitted together with the header bits via an RF medium.

      2. Operation

      Here electrical energy is transformed into sound to send the pulse. The sound that is received back is converted into electricity. Thus the time lag between the sent and received sound signal is used to estimate the distance to the object. Spacing between sensors is dogged by their beam angles. The sensors must be spaced so that they do not interfere with each other. This interference is sometimes referred to as crosstalk. The target should be mounted perpendicular to the axis of the sensor.

   4. RFID Transmitter and Receiver

   RFID tag is a tiny device is represents in Fig 12 that stores and forwards the data to RFID reader. They are characterized in two types active tag and passive tag. Active tags are contains an inherent internal battery and do not demands power from the reader. Stereotypically active tags have a longer distance range than passive tags. Passive tags are slighter and lighter in dimensions than that of the active tags. They do not contain an inbuilt battery and thus they look upon

   1. Decoder HT12D

      The HT12D is a decoder IC made especially to pair with the HT12E encoder. It is a CMOS IC made for remote control system application. The decoder is capable of decoding 8 bits of address (A0-A7) and 4 bits of data (AD8-AD11) information. For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen. The decoders receive serial addresses and data from programmed encoders that are transmitted by a carrier using an RF or an IR transmission medium. They compare the serial input data three times continuously with their local addresses.
