Application Research And Design On Intelligent System Of Chongqing Expressway Network

With the fast growth of domestic expressway, the dimensions of the Expressway Network Tolling System expand rapidly, the road-network structure is more and more complicated, the road-network information expands fast. Especially after the ring-road network takes, one can reach the route and present variety in two charge stations, a traditional one artificial to calculate route information and toll rate form can meet the complicated road network structure already, so, it needs a software of intelligence to calculate route information and toll rate form.The Intelligent system of the road network is the accessory system of the Expressway Network Tolling System. it's an information-based project of Chongqing Communication Commission, it's an item of the Information Project of Chongqing Science & Technology Commission too.In this paper, we introduce that manage the problem faced in operation after the expressway networking charges, explain the background of performing to the road network Intelligent system, faced the question in view of the networking charge system propose the road network Intelligent system general goals and the realization strategy. This paper introduces in detail design and the realization of the road network Intelligent system, unified the Floyd algorithm, the Dijkstra algorithm and the recursion algorithm in detail elaborated the way and the tariff computation realization, enhanced the system operating efficiency using the object dynamic production technology. This article also to the road network intelligent system data structure, the fault-tolerant design, the user interface and so on has made the detailed elaboration, has carried on the brief introduction to the system classical flow and the run-time interface , too. Finally, this paper unifies the specific case showing road network intelligent system practical to be valid, performs to the system application and the promoted value to introduce, including result and economic efficiency which obtainsThe road network intelligent system synthesis has utilized the computer software technology, the software engineering, the algorithm technology, the database technology as well as the highway mechanical and electrical engineering and so on the specialized technical knowledge, will be an essential assistant of scientific and technical operation in the expressway networking charges.
