UML Class Diagram Example for Transport System

This vehicular network diagram sample was drawn on the base of picture illustrating the post "Intelligent transportation system" from the blog "Technology New Here".
"Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities.
The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of increasing population, increasing amount of transportation vehicles and increasing urbanization."

The vehicular network diagram example "Intelligent transportation system" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Vehicular Networking solution from the Computer and Networks area of ConceptDraw Solution Park.

"The Process Flow Chart provides a visual representation of the steps in a process. ...
When to Use:
One of the first activities of a process improvement effort is constructing a flowchart. It provides the following benefits:
1- It give you and everyone a clear understanding of the process.
2- Facilitates teamwork and communication.
3- Helps to identify non-value-added operations."

This TQM diagram example shows a business process that can be then analyzed to improve the effectiveness and diagnose quality issues that require resolution.
This example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Total Quality Management (TQM) Diagrams solution from the Quality area of ConceptDraw Solution Park.

This TQM diagram example was redesigned from the illustration of the Highway Performance Monitoring System (HPMS) Field Manual from the website of the Federal Highway Administration (FHWA).

"Highway Performance Monitoring System (HPMS).
The HPMS is a national level highway information system that includes data on the extent, condition, performance, use and operating characteristics of the nation's highways. The HPMS contains administrative and extent of system information on all public roads, while information on other characteristics is represented in HPMS as a mix of universe and sample data for arterial and collector functional systems. Limited information on travel and paved miles is included in summary form for the lowest functional systems.
HPMS was developed in 1978 as a continuing database, replacing the special biennial condition studies that had been conducted since 1965. The HPMS has been modified several times since its inception. Changes have been made to reflect changes in the highway systems, legislation, and national priorities, to reflect new technology, and to consolidate or streamline reporting requirements."

The TQM flowchart example "Software workflow diagram" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Total Quality Management (TQM) Diagrams solution from the Quality area of ConceptDraw Solution Park.

This diagram sample shows the different situations that cooperative positioning may be helpful for vehicular networks. It was designed on the base of Wikimedia Commons file: CPsituations.jpg.

"Vehicular Ad Hoc Networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) - the spontaneous creation of a wireless network for data exchange - to the domain of vehicles. They are a key component of intelligent transportation systems (ITS).
While, in the early 2000s, VANETs were seen as a mere one-to-one application of MANET principles, they have since then developed into a field of research in their own right. By 2015, the term VANET became mostly synonymous with the more generic term inter-vehicle communication (IVC), although the focus remains on the aspect of spontaneous networking, much less on the use of infrastructure like Road Side Units (RSUs) or cellular networks."
