India ABSTRACT Traffic modeling has become a major issue for many cities throughout the world. There are number of simulation tools and websites available which can depict the urban Traffic situations. Our work extends the concept of Traffic Website Design which should be independent of platform as well as device. Keywords: OPEN(Object Process Environment Notation). 1 INTRODUCTION where the abstract platform is defined. In order to design complex abstract platform, we can use UML In this paper we will be focusing on a web site 20 composite structure to break up a complex design design specially designated for urban Traffic into smaller pieces. Generally for urban traffic commuters as well Traffic Management official. To modeling we have used state-machine and activity begin with we are focusing integration of platform diagrams which encapsulates classifiers to define independent modeling being UML. The concepts that their behaviour. Since the behaviour of the abstract plain UML prescribes for specifying communication platform is also described in UML, it may be between application parts (Objects and components) necessary to continue the explicit and the implicit imply an abstract platform that is based on request abstract platform definition approaches. In the next response model and on message passing. In UML 2.0 half of the paper we will be concentrating of device meta-model, behavioral operations represent the independent website design of urban traffic which capability of classifier to receive and to respond to can provide the information so the common user requests. Requests are sent when objects exercise about traffic conditions on his mobiles, PDA and signal instances, which are sent asynchronously by telephones equipped with speech recognition other objects when these execute send signal actions software's. and Broad cast signal actions. During late 90's it was general conception that The specialization of UML for defining website means it has to be supported by browser of a abstract platform characteristics can be made more personnel computer or a laptop. It is very well shown manageable and clearly defined through the use of by Ginage and Murugesan in their paper on web UML profiles. Profiles are language extensions engineering that by the help of XML/XDL we can consisting of metamodel elements[1,3] that achieve browser loss web providing in basic flexible specialise elements of a reference model. The infrastructure to independently define content and specialised elements can be given specific semantic presentation. We will be using UML modeling variation points. technique to develop the device independent website. To further define an abstract platform model, 2 PLATFORM INDEPENDENT WEB library packages are accommodated in UML 2.0. The MODELING abstract platform model library package can be imported by platform Independent Model of the Consider an example of Traffic information application. Then we will be creating a dependency website in which a user can enquire about the latest between the package where platform independence model is defined and the model library package Traffic conditions on a particular route through Ubiquitous Computing and Communication Journal - 11- online query mechanisms with system 2.2 Discussion of the above model administration. We can call this abstract platform the From the above UML model we are able to Traffic Abstract Platform. In order to define the define the behavioural aspects of components taking composition of the Traffic binding object with the part in a web model designing. Secondly the if a application, we use reachable exchange of designer is following some language then he or she asynchronous signal exchange with the implicit may favour directly some platforms over the other. approach, by defining a UML profile. We can show The UML composite structure proposed in Fig. 2 and the relationship between platform independent Fig. 3. The composite structure of transportation modeling of the application and the abstract website can be created or destroyed along with platform. components to which they are attached if the port The main of modeling elements used in Figure 1 are connecting to them is destroyed first. This implies that if we want to model our unbounded number of class and association. There are certain additional distinct users may use the component through ports : features to enhance the basic conceptual model. We can further extend this abstract modeling for System Device Independent modeling using XML and UML Application concepts.
