Problem Summary

There has been series of problems resulting from poor control of traffic. This has been happening in both developed and developing countries. Lack of proper plans and strategy each year makes road users to encounter the same problems. People spend longer than they estimated their travel time to be, especially in heavy traffic jams, many accidents due to rush have significantly increased and also increase of the pollutants to the environment due to the constant idling of the vehicles as they are not moving.

Heavy noise from impatient drivers hooting their next vehicles in front of them create noise pollution. Poorly developed methods and strategies to avert the situation from the government side have been the major problem ever since. Local government should take the initiative to design the new mechanism to ensure that traffic is decongested to all roads especially to those near the major towns and cities. Another key point to consider is the growing number of private vehicles on the road. This makes the challenge of controlling traffic to be a bit hard.

The same problem is face by Kuwait nearly every day and standard traffic lights which are set up at various junctions in Kuwait operate upon predefined timing schemes, which are set at the time of installation and can be further reset. The timing schemes are arrived by considering normal traffic conditions. There should be different timing schemes for different junctions but many lights operate under a simplified sequence.

This problem has encouraged the need to solve the timing problem. In order to design and develop an effective as well as intelligent traffic control method, a number of factors regarding the condition of roads should be considered. A number of intelligent traffic lights used now a day have sensors which feed a predefined algorithm which in turn control the operation of lights. This algorithm presumes the traffic to be moving smoothly and thereby doesn’t require external management. However, in cases of congestion or any untoward incident, the lights fail to adapt to the scenario.

The proposed RFID traffic control avoids problems that usually arise with standard traffic control systems, especially those related to image processing and beam interruption techniques. This RFID technique deals with a multi-vehicle, multilane, multi road junction area. It provides an efficient time management scheme, in which a dynamic time schedule is worked out in real time for the passage of each traffic column. The real time operation of the system emulates the judgment of a traffic policeman on duty. The number of vehicles in each column and the routing are proprieties, upon which the calculations and the judgments are based.

The main areas for which the RFID traffic system has an advantage over the conventional are the areas of image processing along with beam interruption methods. This method is applicable in case of multi vehicle, multi road junction area and multi lanes. Its changes the algorithms for each traffic lane in real time for smooth traffic flow. It does its job by simulating a traffic policeman’s decisions at the same scenario.

The routing as well as the number of vehicles in each lane are the parameters for the calculations and decisions. The RFID consists of four important parts, the AersoScout RFID tags, the Cisco access point, the Wide Area Network along with the Cisco location server. The responsibilities of the parts are simulating moving vehicles, detecting the RFID tags, simulating the omnipresent surroundings and the RFID software respectively.

The microcontroller of the system is the location server. It feeds the location and the time of tagging from the sensors through the internet to the management system. The system then processes the incoming information and takes decisions accordingly to control the traffic. The detailed diagram showing the working is given below: -

objectives that the material will cover are as follows: -

a) To understand the use of RFID system in managing traffic issues.

b) To understand the problem associated with static traffic light and how dynamic traffic light using RFID will solve the problem.

c) To understand the working of static and dynamic traffic light system.

d) To understand how dynamic system will help in improving quality of services to Emergency vehicles, violation system and tracing out of stolen vehicles using RFID.
