Abstract
In an intelligent smart city like Sejong city in Korea, automatic and smart software is absolutely necessary for autonomous traffic and vehicles control systems. Therefore, these systems need to have an accurate and timely performance; otherwise, safety issues may arise. To resolve this, we propose our code visualization approach to adapt an object-oriented smart traffic control simulator, which analyzes Java code’s complexity and identifies bad codes against performance. To achieve an accurate performance, we must repeatedly perform refactoring until attaining a range of system-defined performances through effective code visualization. As a result, we enhance the code complexity of the cyber-physical system-based software to achieve the exact performance. With this approach, we expect to obtain an accurate performance and complexity improvement of the object-oriented traffic control simulator without significant power consumption.
Highlights
In the fourth Industrial Revolution, the smart Sejong city in Korea is focused on solving energy and transportation problems including environmental monitoring, traffic information analysis, utility monitoring, public transportation, and incident reporting
This tool can simulate a variety of environments and situations before operating a real smart traffic control system
After identifying CarModule with the highest coupling value of baseline time in terms of the level of the coupling mechanism in Table 5, we focus on improving the performance degradation factors of CarModule
Summary
In the fourth Industrial Revolution, the smart Sejong city in Korea is focused on solving energy and transportation problems including environmental monitoring, traffic information analysis, utility monitoring, public transportation, and incident reporting. Development of smart cities requires smart technologies and smart infrastructure. Software plays a key role in integrating these technologies. The cyber-physical system (CPS) technology is used to monitor and integrate smart city technologies [1,2]. CPS may include an extended concept of the existing embedded system, which has limited resources such as available power and memory and performance limitations leading to several operational problems [3]. It is necessary that the software should operate reliably to deliver a high performance even in a limited resource environment
