What challenge/problem are you trying to solve through your application:
•You are at a traffic signal and in front of you there is a big truck blocking the view of the signal. Come up with a solution as how can you be able to view the signal
•How we can tackle the issue of noise pollution through use of electronics in vehicles. E.g.. Developing Soundless horns
•During winter season, visibility is limited because of fog both during early morning and night. Can you think of a solution that uses a sensor in order to detect the obstacles and alert the driver
How does your application solves the above mentioned challenge/problem:
The proposed system overcomes these problems by using RF Rx to know traffic signal. FM Tx/Rx is used for soundless digital horn to reduce sound pollution and ultrasonic sensor is used to detect the vehicles and objects when visibility is low.
1. The RF transmitter continuously transmits traffic signals. The RF receiver placed in vehicle receives the signal from the RF transmitter and received signal is decoded using decoder and shows traffic status to driver in his vehicle.
2. Whenever driver wants to horn he can intimate the surrounding vehicles by pressing FM transmitter switch which transmits signal to the surrounding vehicles. The FM receiver inside the vehicle receives the signal from FM transmitter and gives display and sound indication only to the driver.
3. Ultrasonic sensor is placed in front of the vehicle If there is any obstacle or vehicle in front of the vehicle, the signal transmitted by ultrasonic is reflected back and is received by the ultrasonic receiver. The received signal is given to the controller to give display and sound indication to the driver.
Description of Project:
The main concept in this system is to reduce accidents and noise pollution due to vehicle. When a vehicle is at a traffic signal and in front of the vehicle there is a big truck blocking the view of the signal, this can lead to an accident because the present system does not display the lane status in vehicle i.e. whether the signal is red or green. The proposed project uses RF transmitter at the traffic junction to transmit the current status of traffic signals of each lane. The RF receiver in the vehicle receives the status of traffic signal from the RF transmitter which is located at traffic junction. A microcontroller is used at transmitter in order to control the sequence of the traffic signal in round robin fashion. The present systems are based on static approach, in which the time is allocated to a path is fixed irrespective of amount of traffic flowing on that path. In this system density controlled traffic signaling is used which allocates the time to each lane depending on the density of vehicles.
The proposed system uses RF transmitter at the traffic junction, a RF receiver is placed inside the vehicle which receives the traffic information transmitted by the transmitter at the junction. Using RF we can achieve up to 100meter range i.e. 100meter before the traffic junction, lane information is displayed in vehicle.
The horning of vehicles is increasing with traffic and number of vehicle, this leads to sound pollution. Especially near schools, colleges, hospitals and at traffic junction the sound pollution is more due to the vehicle horning. The digital horn proposed in this system avoids this sound pollution using FM transceiver placed in vehicle whenever the driver wants to horn, a code is sent to the surrounding vehicles using the FM transmitter, the code is received by the surrounding vehicle using FM receiver and the horn is identified.
Many times, while raining and in early morning the driver unable to see the objects in front of vehicle this leads to accidents. Here the system uses the ultrasonic sensor mounted on front of vehicle which detects the objects and informs the driver. For the sound less digital horn and obstacle detection we are using interrupt programming and highest priority is given to the obstacle detection since it important than horn.
CONCLUSION:
In this paper it is showed that the transmission of traffic signals to the vehicles will assist the driver to get the traffic information in the car itself. The traffic information which is transmitted is a density based i.e. the amount of time given to each lane depends on the number of vehicles waiting at the traffic pole in that lane. This will solve the problem both static traffic signaling and the visibility of traffic lights in case of any big abstraction. The use of FM transreceivers as digital horn will reduce the sound pollution caused by the vehicles and makes the system environment friendly. This will help the driver when all wind shields are closed and the driver cannot hear the outside sound. The use of ultrasonic detector as an obstacle detector will ensure vehicle safety by indicating the presence of obstacle to driver. This will reduce the number of accidents due to low visibility. The system uses a simple micro controller and RF transreceivers and ultra sonic detector to accomplish the above mentioned processes. The system is cost effective and needs less maintenance.
