Applying SOFL to Constructing a Smart Traffic Light Specification

摘要

Smart Traffic Light (STL) is a system for controlling traffic lights based on patterns of traffic loads in related intersection. Since this is a safety-critical system, we need to construct an accurate specification to build a firm foundation for implementation of the system. In this paper, we describe how the SOFL formal engineering method is applied to construct a Smart Traffic Light specification through the three-step modeling approach of SOFL that helps us manage the complexity and difficulty of constructing a formal specification.
