Design And Implementation Of Traffic Guidance Service Platform Based On PHP Technology

With a top speed of expansion of city size, the city has been unable to catch up with the traffic rate of expansion of resources of the city. Due to intense traffic resources, led to a series of social problems:traffic jams, accidents frequent, lengthy travel time and so on. With nearly two things, vehicle networking, car road big data collaboration and the Internet to flourish, the integration of intelligent traffic guidance systems in various fields leading technology emerged. However, the current traffic guidance service platform exists the following problems:You can not carry a large number of users, developers and test cycle is very long, massive data processing capacity can not keep up.In this paper, the research frontier in research in various fields, the response to these problems put forward a set of targeted solutions. PHP is currently the most efficient development of language, and therefore induced by PHP development services platform has a unique advantage. In order to ensure a platform capable of supporting the service requests mass, this paper presents a distributed system architecture allows the system to smoothly achieve horizontal expansion. Due to performance bottlenecks PHP language itself, so a core algorithm implementation and migration HHVM C extensions to ensure the performance of the system is not shackles.Meanwhile, this paper presents a new algorithm for heterogeneous sensor nodes deployed, can greatly improve the efficiency of network nodes deployed. Through seamless integration RSSI, GPS, INS inertial navigation system, a multi-mode convergence differential Speedway under fusion location algorithm. Collected by floating car OD matrix parameters of road network, the traditional Dijkstra algorithm optimization, we propose a funny dynamic guidance algorithm.Finally, the above theoretical analysis and research, said in an open private cloud host implementation and the deployment of traffic guidance service platform demonstration system, and some of the key features were tested and analyzed, in line with expectations.
