Research Of Limited-speed System On The Superhighway

It is a problem to control limited-speed of vehicle on the superhighway reasonability with concerned and researched by all countries transportation. In each country , it is certain that limited-speed of vehicle influence transportation safety soon. But it is different that made order and measure to limited-speed because of actual status difference in each country. Even if a same nation, under the different stage, different period, different region and economic term, to the limited-speed that not proper adoption one of limited-speed speed limit system that the highway is soon worth, but is should according to main road of actual line, transportation, weather... etc. Of superhighway the term adoption is the most reasonable, the most economic safe limited-speed is soon, and this is variable to control.This study speed for device for variable limited-speed for research to manufacturing expert system is pointing installing establishing on the superhighway, can according to weather, road condition and vehicle etc. term automatically proceeding variable limited-speed soon, it can making the highway the transportation on the trunk line the traffic with the current road segment changes of term transportation but variety, from but biggest limit ground guarantee the transportation the safety, the traffic is even, stability, guarantee tallest road to go through the ability at the same time with the transit efficiency.On the item' s research target, this study new concept for bring upping automatically variable limited-speed soon showing the technique, established the limited-speed soon mathematics model, realizes the limited-speed is soon expert system. That technique and domestic and international of the same kind technique comparison, realizes automatic road condition examination, the automatic limited-speed soon show, control from a distance the intelligence report show with have the independent work and so forth of function. In the aegis line car safety, let up economy lose with increase the highway to go through the efficiency to wait the aspect to all have the important meaning with practical value.
