Design of Adaptive Road Traffic Control System through Unified Modeling Language

In recent years, Unified Modeling Language (UML) has become most popular among modeling languages. UML is commonly used in the design and implementation of any system and software architectures. UML models help to achieve functional and non-functional requirements of the system. Furthermore, UML tools have enabled the creation of source code from UML diagrams in order to initiate the programming phase of building software. However, due to lack of clearly defined semantics in UML, creating source code from UML models have become challenging. Hence different UML diagrams have been used to represent the functionality of the system. The main objective of this paper is to model an Adaptive Road Traffic Control System using UML. Traffic congestion is an ever increasing problem in towns and cities all over the world. Local authorities must continually work to maximize the efficiency of their road networks and to minimize any disruptions caused by accidents and events. In this paper we proposed a UML model for an Adaptive Road Traffic Control system which provides a technique for controlling the traffic in highway network using signals that are automatically controlled by detectors. It coordinates the operation of the traffic signals in entire area (city or town) to give good progression to vehicles through the road network. Whilst coordinating all the signals, the signal timing fluctuates throughout the day, responding intelligently and continuously as per the changes in traffic flow. It removes the dependence of less sophisticated systems on signal plans, which have to be expensively updated.
