Traffic Controller System Data flow diagram is often used as a preliminary step to create an overview of the Traffic without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Traffic process. It contains all of the userflow and their entities such all the flow of Traffic, Routes, Length, Traffic Police, Diversions, Traffic Light, Login. All of the below diagrams has been used for the visualization of data processing and structured design of the Traffic process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Traffic Controller System :
This is the Zero Level DFD of Traffic Controller System, where we have eloborated the high level process of Traffic. It’s a basic overview of the whole Traffic Controller System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Diversions,Traffic Light and Login showing the system as a single high-level process, with its relationship to external entities of Traffic,Routes and Length. It should be easily understood by a wide audience, including Traffic,Length and Diversions In zero leve DFD of Traffic Controller System, we have described the high level flow of the Traffic system.High Level Entities and proccess flow of Traffic Controller System:
- Managing all the Traffic
- Managing all the Routes
- Managing all the Length
- Managing all the Traffic Police
- Managing all the Diversions
- Managing all the Traffic Light
- Managing all the Login
First Level Data flow Diagram(1st Level DFD) of Traffic Controller System :
First Level DFD (1st Level) of Traffic Controller System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Traffic Controller System system as a whole. It also identifies internal data stores of Login, Traffic Light, Diversions, Traffic Police, Length that must be present in order for the Traffic system to do its job, and shows the flow of data between the various parts of Traffic, Length, Traffic Light, Login, Diversions of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Traffic.Main entities and output of First Level DFD (1st Level DFD):
- Processing Traffic records and generate report of all Traffic
- Processing Routes records and generate report of all Routes
- Processing Length records and generate report of all Length
- Processing Traffic Police records and generate report of all Traffic Police
- Processing Diversions records and generate report of all Diversions
- Processing Traffic Light records and generate report of all Traffic Light
- Processing Login records and generate report of all Login
Second Level Data flow Diagram(2nd Level DFD) of Traffic Controller System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Traffic. It may require more functionalities of Traffic to reach the necessary level of detail about the Traffic functioning. First Level DFD (1st Level) of Traffic Controller System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Traffic Light, Diversions, Traffic Police, Length, Routes, Traffic.Low level functionalities of Traffic Controller System
- Admin logins to the system and manage all the functionalities of Traffic Controller System
- Admin can add, edit, delete and view the records of Traffic, Length, Diversions, Login
- Admin can manage all the details of Routes, Traffic Police, Traffic Light
- Admin can also generate reports of Traffic, Routes, Length, Traffic Police, Diversions, Traffic Light
- Admin can search the details of Routes, Diversions, Traffic Light
- Admin can apply different level of filters on report of Traffic, Traffic Police, Diversions
- Admin can tracks the detailed information of Routes, Length, Traffic Police, , Diversions
