So, it minimizes the number of accidents involving emergency vehicles nowadays during emergency case. The Radio Frequency (RF) transmitter and receiver circuit is the main circuit in the system. The RF transmitter circuit has the transmitter module and encoder to send the signal to the RF receiver circuit. The RF receiver circuit has a receiver module to receive the signal and decoder to convert the signal into original signal and send it to the output. The RF receiver circuit is combining with the traffic light circuit control by arm based LPC 2148 processor. Traffic lights play an imperative role in traffic management. Traffic lights play an important role in the traffic management. Existing Automatic Traffic Light Violation Detection System is based on the camera’s to detect the violator. This system has a number of limitations like blurry image due to motion , poor image resolution because the number plate is far away, poor lightening, different fonts . The proposed system improves the accuracy of Automatic Traffic Light Violation Detection system as well as helps to trace out the stolen vehicles using RFID. The real time implementation of both the modules, which are named as The traffic light control system for emergency vehicles Automatic detection of traffic signal violation is one of the ways in saving lives making the traffic system safe, driver friendly and convenient at the same time as well. Dept of ECE, NHCE 1 Traffic light control for emergency vehicles & Automatic detection of signal violation CHAPTER 2 2.1 LITERATURE SURVEY 2.1.1 Overview Literature survey is the most important step in development process. Before developing the tool it is necessary to determine the time factor, economy and company strength. Once these things are satisfied, then next steps is to determine which operating system and language can be used for developing the tool. Once the programmers start building the tool the programmers need lot of external support. This support can be obtained from senior programmers, from book or from websites. Before building the system the above consideration are taken into account for developing the proposed system. This chapter will explain the research related to the wireless communication system and how the knowledge can be manipulated to make use of “Intelligence RF Traffic Light Control for Ambulance”. Next, the basic information about component parts will be discussed briefly. This chapter increase deeper understanding about basic wireless communication system and several component parts are use according. 2.1.2 Current Study of Traffic Light Road signs in Malaysia are standardized road signs similar to those used in other nations but with certain distinctions. Until the early 1980s, Malaysia closely followed Australian and Japanese practice in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Signs usually use the series fonts (Highway Gothic) typeface also used in the United States, Canada, and Australia, although some signs on recently completed expressways use transport heavy Malaysian traffic signs use Malay, the official and national language in Malaysia. The use of traffic lights to control the movement of traffic differs regionally and internationally in certain respects. In Malaysia, flashing red is the equivalent of a stop sign while flashing yellow indicates that the opposing traffic may enter the intersection at any time, but drivers should exercise Dept of ECE, NHCE 2 Traffic light control for emergency vehicles & Automatic detection of signal violation caution. This may be used when there is a malfunction with the signals, or late at night when there is little traffic. A single four-way flashing yellow light (with no red light above or green below) may be used at more major intersections on otherwise fast, low traffic rural roads (where full traffic lights or four-way stop signs may not be entirely appropriate, and static Stop/Yield signs may be ignored, obscured, or even stolen) as an advanced warning to slow down and proceed across with caution.
