Design And Realization Of The Intelligent Transportation Information Issuing System Based On IOS

With the development of socio-economic and people’s living conditions, the process of urbanization continues to accelerate. Vehicles is greatly increased, which is much larger than the growth rate of roads and other transport facilities. Therefore, a series of traffic problems such as traffic congestion, surging accident, and pollution. That has caused energy waste and economic losses. Proofed by the theory and practice at home and abroad, the implementation of ITS is the main way to solve the traffic problems. It’s not only beneficial to the traffic security and roads efficiency improvement,but also to the rational use of land and energy, the improvement of environmental pollution and noise, health and sustainable development of national economy.As the last tache of ITS, information issuance system is also the kernel tache, which integrates Global Satellite Positioning Technology, Geographical Information Systems, Modern Communication Technology and Technique of Database, to realize real time information issuance, and to help drivers to reach the destination exactly, safely and rapidly. It is very important to improve roads utilization and relieve traffic pressure.Based on the development of the traffic information issuance system and combined with the advanced iPhone operating system, geographic information technologies and artificial intelligence theory, this article design a kind of traffic information issuance system based on the iso. This system has four functions:Firstly, the system has realized the function of positioning and map display. The function could display your position and update it in real time., users can get the information of nearby roads, hospitals, schools and hotels by sliding the screen, it also could zoom in and out the map.Secondly, the system has realized the function of displaying geographic information. The function can display the view of geographic information, and the view shows the latitude, longitude, sea level, the display accuracy and driving distance. Users can get the information such as the latitude of his position.Thirdly, the system has realized the function of searching. The view of the function has search bar and a picker, and based on the similarity, the picker will show series of positions to be selected, and the result display information of the selected position.Fourthly, the system has realized dynamic route guidance function. This function is mainly to get the shortest route. When users want to get to a place, he can enter the initial position and the destination using the picker to select the positions. Then click the search button, and we could get the best route. Nowadays, most route guidance system use the Dijkstra algorithm. Although it could get the best route, it has to check many nodes, with a lower operating efficiency, and it is generally used in static situations. So this algorithm could not meet the users’dynamic demand. Here we use the dynamic route guidance algorithm based on artificial immune theory, and the result shows that this algorithm operating efficiency is high and the results are accurate. Moreover, this algorithm, referring to immune memory function of biologic immune system, can get K suboptimal paths without any calculations again. It not only balances network load reasonably,but also avoids local jams. This algorithm can meet the requirements of dynamic route guidance system better. This paper based on applying this algorithm to mobile terminal equipment to get optimal path, to some degrees, has some referential significances.Based on the research above, we finally give the implementation results of the system, make a conclusion and propose the future research in this direction.
