1. Common goal:
Now the intelligent transportation domain information platform has two kinds;
First: "GPS satellite navigational system" information platform.
Second: "The highway 拖影 type dynamic total information system" the patent technology provides "拖影 the type dynamic total information system" the information platform.
These two kind of information platform common goal is;
Real-time provides, accurate, the highly effective information platform, provides the basic security for the highway traffic transportation, quickly guaranteed. It is the advanced information technology, the data communication technology, the electronic control technology and the computer processing technology and so on, effectively synthesizes applies to the ground traffic control system, thus establishes one kind of wide range, the omni-directional display function, real-time, accurate, highly effective intelligence transportation system.
These two kinds do not use the information platform uses different information gathering, the transmission mode, has the different application effect, in order to analyze this different effect, it is necessary to carry on the comparison to these two kind of information platform, in order to enhances strong points and avoid weaknesses maximum limit plays the information platform role which these two kinds does not use. With the smallest investment, obtains the greatest income.

Two: Two kind of information platforms basic situation:
1, "GPS satellite navigational system" information platform.
Depends upon the information platform which the GPS satellite navigation provides, GPS by three big subsystems constitutes: Space satellite system, ground monitoring system, user receiving system. The space satellite system by evenly distributes in 6 tracks planes 24 high track works satellite constitution, the spatial satellite is away from the ground 12,000 kilometers upper airs, every 12 hours circle an Earth week. The ground monitoring system by evenly distributes in the US territory and on the three principal oceans United States military base 5 inspection stations, a master station and three 注入?constitutions. This system function is: Carries on the monitor, the control to the space satellite system, and pours into the renewal to each satellite the navigation telegram text. The GPS satellite has two kind of data codes to the user communities transmission navigation telegram text, one kind for is the precise code, the precise code survey result may achieve the millimeter level precision, US for own benefit, only supplies the American military, the governmental agency as well as obtains the civil user use which the American government authorizes, another kind is the thick code, its localization and the time precision are low, at present, the world civil guest average per household may not limit the free use. In the civil customer the single plane pointing accuracy general several hundred meters, surpass 10 meters compared with the good pointing accuracy. At present in the world uses the GPS satellite navigational system all is US which uses launches and the control navigation satellite, China has a slang, calls innately 自便. In order to prevent American coercing with the control, China and European Union has "the Galileo project cooperation" the plan, the plan development belongs to the navigation satellite which China and European Union altogether has, at the appointed time our Chinese also had own precise code, again is not discriminated the others.
The GPS satellite navigation is by the GPS receiver, receives the GPS satellite signal (above three), extracts this information and so on spot latitude and longitude coordinates, speed, time. In order to increase the automobile navigation pointing accuracy, usually uses the difference GPS technology. When the automobile goes to the underground tunnel, the high level buildings cluster, the highway and so on covers up thing when with capture not to GPS satellite signal, the system may automatically induct the autonomy guidance system, this time examines the automobile by the vehicle speed sensor the approaching speed, through the micro processing unit data processing, directly figures out the advance from the speed and the time the distance, the gyroscopic sensor directly examines the advance the direction, the gyroscope also can automatically save each kind of data, even if when replaces the tire temporarily stops, the system also may reestablish.
Automobile position coordinates data, advance direction measure which from the GPS satellite navigation and the autonomy navigation all with actual travel route path existence certain error, in order to revise these two errors, unifies with the map on route, must use the map match technology, adds a map match circuit, the path error carries on the real-time correlation match to on the automobile travel route and the electronic map to make the automatic revision, this time the map match circuit is carries on fast processing through the micro processing unit reorganization procedure, obtains the automobile on electronic map correct position, instructs the correct travel route. CD-ROM uses in to save information and so on path data, the LCD monitor uses in to demonstrate the navigation the related information.
