The Test And Detect Speed Module Algorithm Improvement Of TTS System

The main research of the paper is the test and detect speed module algorithm improvement of TTS system. TTS system is a advanced level system of 97 intersections to collect,analyze,manage and issue traffic travel time in some city. Software test is a important loop in TTS system's software development. Software test can avoid producing of error and eliminate error which was produced. It can make the error of program to low grade. It ensure consign high-quality and high-powered system to users.There were four works in the paper. One is test of TTS system video collection part, the second is test of TTS system detect speed module, the third is test of TTS system user interface, the forth is detect speed module algorithm improvement.Video collection part of TTS system is video collection module of forward equipment which is installed in the intersection. It can inspect automobile in the roadway and capture their vehicle-plate. Forward equipment will send the information of vehicle-plate and vehicle stream to the center system. Author tested camera control,shields and so on. Detect speed module of TTS system is a kernel module which used in communication equipment. Detect speed module can estimate if vehicle run in excessive speed. If vehicle run in excessive speed, the information of vehicle will enter blacklist police. TTS system user interface test is mainly test user interface whether according with criterion,such as intuitional, consistency,agility,easiness,correctness,practicability. The improvement of detect speed module algorithm mainly is using virtual loop instead of practical inductive loop,though setting a threshold, we can verdict whether vehicle passed the loop or not. After vehicle passed the front loop and the back loop, we can use vehicle's run-time and distance calculating vehicle's speed. Because detect equipment is practical inductive loop before algorithm improvement, its maintenance and installation...
