The Design Of Sensory Data Based Traffic Information Management And Service System Software Architecture

The obtaining of real-time traffic information has become an important part of theTraffic Information Management and Service System (TIMSS) and the sensory Databased traffic flow estimation and prediction is more accurate. The real-time, dynamicand predicted traffic information applied in traffic management and service, helpingthe process of traffic management business. With the Increasing pressure andcomplexity of system engineering, SA guidance theory and method is urgently neededto ensure the construction quality and maturity of TIMSS. The article conducted thetraffic management system domain system structure design, mainly made thefollowing research achievements:1. Proposed the domain model of TIMSS. According to the domain of TIMSS,the mandatory requirement, domain variability and boundary is identify to establishthe domain model, and the composition of the domain model (scene model, rolemodel, information model, feature model, business model) are described throughontology language.2. Proposed the TIMSS SA. Based on the Domain Specific Software Structure(DSSA)，the solution about the requirement of TIMSS domain model is described andthe core model of the SA is defined. We designed reasonable components, connectorsand configuration, used Z-language to realize the formalization description of SA.3. Based on domain SA, we formed a TIMSS framework, designed anddeveloped prototype system. We preliminary probed into the TIMSS systemimplementation and application process based on the SA design, to draw out of othersmore valuable opinions upon the TIMSS development.This topic extracted from the actual construction requirements and experience ofTIMSS. The research results will be used to guide future research. This article madedomain engineering methodology as a guide. It is a good innovation on domainmodeling and SA design of traffic management and has a certain guiding significancein this domain.
